How You Can Charge Your EV If You Don't Own a House (yahoo.com) 186

"According to one study, homeowners are three times more likely than renters to own an electric vehicle," writes the Washington Post. But others still have options: Drivers who park on the street have found novel ways to charge their vehicles, using extension cords running over the sidewalk or even into the branches of a nearby tree... [S]ome municipalities explicitly allow over-the-sidewalk charging as part of a broader strategy to cut transportation emissions... In some areas, homeowners can also hire an electrician to run power under the sidewalk to a curbside charging port. But homeowners should check local rules and permitting requirements for curbside charging. In some highly EV-friendly cities, local governments will cover the costs. In Seattle, a pilot program is installing faster curbside charging to residents who opt in to the program...

If home charging simply isn't an option, some drivers rely on public charging — either using workplace chargers or charging occasionally on DC fast chargers, which can bring an EV battery from 0 to 80 percent in around 20 minutes. The problem is that public charging is more expensive than charging at home — although in most places, still less expensive than gas... For drivers who have access to Tesla superchargers, public charging might still be a solid option — but for non-Tesla drivers, it's still a challenge. Many fast chargers can be broken for days or weeks on end, or can be crowded with other drivers. The popular charging app PlugShare can help EV owners find available charging ports, but relying on public fast charging can quickly become a pain for drivers used to quickly filling up on gas. In those situations, a plug-in hybrid or regular hybrid car might be a better option.

And beyond that, "experts say that there are a key few steps that renters or condo owners can take to access charging," according to the article: The first is looking up local "right-to-charge" laws — regulations that require homeowners' associations or landlords to allow residents to install Level 1 or Level 2 charging. Ten states have "right-to-charge" laws on the books. In California and Colorado, for example, renters or homeowners have the right to install charging at their private parking space or, in some cases, in a public area at their apartment building. Other states, including Florida, Hawaii and New Jersey, have similar but limited laws. Residents can also reach out to landlords or property owners directly and make the case for installing charging infrastructure. All of this "puts a fair amount of onus on the driver," said Ben Prochazka, the executive director of the Electrification Coalition. But, he added, many EV advocacy groups are working on changing building codes in cities and states so that all multifamily homes with parking have to be "EV-ready."
Ingrid Malmgren, policy director at the EV advocacy group Plug In America, tells the newspaper that "communities all over the country are coming up with creative solutions. And it's just going to get easier and easier."

      It should also be understood that when Tesla owners enable their security features when not driving, the burn-down of the battery is incredible, and apartment dwellers are more likely to do this than private garage owners. For people who fill up the gas cars and then don't drive for a week, they won't understand how that is a terrible idea for a Tesla. If you're a Tesla owner you have to turn off that stupid sentry shit or be prepared to see half of more of your charge consumed running computers to watch the cameras. No shit.

      No consideration has ever been given for Tesla owners who don't have access to a private garage with charging and WiFi. You do it Musk's way or FU.

        You mean, you do it Musk's way or you go into the car settings and flip a switch.

        I say this respectfully, but of all the possible things Elon may or may not have done wrong, giving customers the choice to have their camera watch and record motion seems like really small fries.

        At the absolute most, you're complaining about whether the switch is on or off by default (or always prompts the user for a setting during initial car setup). A veritable molehill.

        Have they removed the ultrasonic sensors from Teslas? Seems like you could just use those to determine when to turn the cameras on, rather than doing machine vision.

        Or use an accelerometer to determine when something bumps the car. That's was a lot of dashcams do.

      Apartments are a problem for charging. In one apartment block built only 6 years ago the developer did not plan on huge upgrades to the electrical supply and when owners starting asking for chargers they had to deny the request after determining only 4-6 chargers (they have over 250 apartments) would exceed the supply to the building. so who will get those chargers and shared chargers mean constantly shifting cars or aggravation when someone doesn't move their charged vehicle. Even buildings built last year lack enough supply for charging. Recent changes in Building code now requires 100% of spaces to be able supply 12KwH between 11pm and 7am In our above example thats 3 Megawatts minimum (many apartments have 2 spaces BTW so 4.5 MwH) the area where that building is has over 150 buildings similar to that, now we need a new power station.
      • You can build as many chargers as you want, you just can't have them all charge at the same time. 250 appartments and capacity for 6 charging at the same time means every appartment gets half an hour per day, a quarter hour if all charging is done at night. That is a bit scant if you're looking at a future with 100% electric cars, but an immediate upgrade of the building power station is probably unnecessary.

        If the building code requires each space to be able to supply 12 kWh in an 8 hour window, that's a t

      • by AmiMoJo ( 196126 )

        The solution is a group of chargers that share power. With a decent system they can actually measure the load on the entire building and use what is left over for charging. People with houses sometimes have them so they can e.g. run an electric shower and hob without overloading the supply when the car is plugged in.

          No. The solution is another drop from the local utility's transformer with 30-40 charging stations for an apartment unit of 250.
      • I don't own nor will I ever own an electric car. I just don't have that kind of money to spend on something. That means I have to subsidize these charging networks.

        If apartments were more competitive that would be less of an issue because there would be pressure to keep prices down but with the complete lack of competition in that market thanks to massive mergers and buyouts and apartment companies using apps to collude on pricing they can just pass the cost directly on to renters.

      for Chicago. A bunch of people in apartments had been using super chargers for their teslas, when the snow came and the temps got super cold there was a huge spike in demand for chargers and a lot of them couldn't get hooked up in time before their batteries died (not that long in the cold, since extreme cold kills range), resulting in a huge mess where they'd clog up the charging stations waiting for tows...

      It's a bit more complicated than that. Cold itself doesn't "kill range". Cold lowers your range by O(10%) at a few degrees below freezing because of differences in wind resistance when the air is more dense, higher rolling resistance on the tires, etc. The impact isn't reallythat big.

      Using the heat to keep the car warm, however, can lower the range by close to half if your car is one of the older ones with resistance heat. Newer, heat-pump-based cars don't take nearly as much of a hit. The seat heater is also a useful alternative to heating up the entire car if you're not planning a long trip, because that uses way less power. Using the seat heaters plus resistance heat, of course, has a horrible range impact.

      The bigger problem, however, is that temperatures make charging time increase pretty dramatically, by half an hour or more per charge session, because your car first must bring the battery up to a temperature where it can actually accept a charge. So instead of a Model Y charging to 80% in 27 minutes, it might take an hour, and instead of a Model X taking 75 minutes to reach 90%, it might take two hours.

      And although Tesla tries to preheat the battery on your way to the Supercharger (preconditioning), if the supercharger is completely full and you have to wait an hour after you get there, A. you've wasted power preconditioning for no reason, and B. the battery is going to cool back down before you plug in. Thus, you still pay the battery heating time penalty when you plug into the supercharger, but because you also used extra power on the unnecessary first preconditioning, you also pay an additional time hit to replace the energy spent for that extra unnecessary preconditioning.

      So there are lots of factors here:

      • A supercharger network that, in many cities, stays frequently at or near its limit during peak hours even in normal weather
      • Longer charge times because of battery heating time
      • Cars coming in with a lower SoC because the car preheats the battery two or three hours too early
      • People charging their cars to higher levels of charge "just in case they need more power than usual"
      • A complete lack of any sort of reservation system for the stalls
      • People therefore having to wait in their cars for 3+ hours with resistance heat and seat heaters turned on

      Between those factors, you have a recipe for people running out of power before they can charge if they come in at too low a state-of-charge.

      Tesla desperately needs a proper reservation system at superchargers. In fact, Tesla desperately needs to figure out which stall is best for incoming vehicles based on their state of charge. Sometimes, it might be faster for a car that's really low on charge to wait a couple of extra minutes to plug in and get on a group of chargers that will give them 250kW charging speed versus one where everybody else just plugged in and they'll get 120 kW or less.

      And having a functioning reservation system would entirely solve this problem, because people could see that they're going to have to wait three hours, and could go to a different, less busy supercharger before they get there, and if that isn't possible, they could at least leave their car and go inside a store and wait, rather than continuing to burn huge amounts of power to keep the car warm while they're waiting for a charger to open up.

      We've been complaining about the lack of a reservation system for many years now. Here's hoping this huge black mark will cause Tesla's management to pull their heads out of their collective a**es and finally implement it.

        My first Leaf had a heat pump, and it cost about 5% range with a full battery. Assuming you had it running constantly, but of course once heated up it cycled on and off.

        Typically heat pumps in cars are about 3kW peak, which handles both the cabin and battery. Maintaining cabin temperature is usually around 500W average, in very cold weather.

    • by Entropius ( 188861 ) on Sunday January 28, 2024 @12:03AM (#64193706)

      What happened here has been misstated a bit.

      The pile-up at the superchargers involved a lot of Uber drivers who had been using them -- not necessarily apartment dwellers. And a lot of those folks weren't especially familiar with the cars.

      Cold does three things to batteries: 1) it dramatically reduces the rate at which they can be charged, 2) it reduces the voltage they will supply at any given state of charge, 3) it creates increased demand for their energy to heat things up.

      As the experience of a ton of Canadians and Norwegians shows, Teslas and other EV's are fine in the cold. They can use the stored energy in their battery to warm said battery up, then go on about their merry way doing whatever they would do. If they're plugged in to a slower charger, they can even pre-warm the battery in preparation for departure. When it's moderately cold the waste heat from the motor/inverter/battery is enough to keep the battery warm; when it's extremely cold the battery needs to supply some extra power to do this.

      The problem here was the charging side. These batteries charge slowly in the cold and need to be preheated or "preconditioned" -- it prefers to be at 50 Celsius for fastest charging. I believe on Teslas you do this by putting a Supercharger address into the car's sat-nav, and it will figure this out and time the preheating so it's ready to charge when you get there.

      The trouble is that people showed up at the Supercharger not knowing to do this. So they plug in, their battery's at -20C, and it is charging VERY slowly until it gets heated up.

      Meanwhile there's a line of people waiting in the cold. Some of them probably properly preconditioned their batteries -- which is the right thing to do if you're about to connect to the Supercharger. But they get there and all the plugs are taken up by people charging at 5 kW with frozen batteries. Theirs are nice and toasty, but they are waiting in line to get there ... while continuing to expend energy keeping their batteries at temperature. At some point they have to either turn off preconditioning or run out of energy, leading to a cascade failure.

      This could have been solved with either better education about preconditioning or access to more plentiful slower ("Level 2") chargers. I don't know how those are in Chicago, but there are a zillion where I live in Syracuse.

    I get this is probably modeled after laws allowing renters to install better security, like deadbolts in doors and such.

    But putting in a Level 2 charger isn't chump change. I would seriously doubt anyone renting is planning on ponying up that much expense...in a rental.

    If it meant the 'gov' had to come do it, that's one thing. And it would increase the value for the landlord. Win/win really.

      Charger installation is around $1000 in the UK, including the cost of the charger itself. You save more than that in the first year of use, so it shouldn't be too much of an issue for tenants.

      But really the better option is to have landlords do it, because when the tenant leaves they can't take the installation with them.

My home is only 10 years old, and only has a 100 amp main breaker because in Oklahoma homes are built for natural gas (central heat, water heater, stove). If we had A/C on, the dryer running, and were charging a car we could easily trip the main breaker. It would cost quite a bit to upgrade the feed to the house and replace the breaker box.

I searched for some great news on hydrogen as a fuel before and I found plenty of items showing how hydrogen as a fuel is a really bad idea. Assume I did do a search just seconds ago and I could not find anything good from MIT on hydrogen fuel, how would you respond? My guess is do your own search, using search terms you didn't specify in your or

        • I agree, you are not my research assistant. What you are is someone that made a claim that hydrogen is some great alternative as zero-carbon alternative to fossil fuels, and you cited no source on this but instead gave some vague statement that there's supporting documents to find.

    • You can do Google searches to verify that: (1) the number of hydrogen fuel stations is about 1000 times less than the number of EV charging stations; and (2) the number of hydrogen-powered cars is about 1000 times less than the number of EVs. So even if a hydrogen-powered car is a good idea (and I don't think it is), the adoption rate for hydrogen cars and fueling infrastructure is so far behind that of EVs that there is very little chance of hydrogen cars succeeding at becoming mainstream.

    If municipalities are going to allow a power cord thrown over the fence, why not allow a householder to sell their electricity supply to whomever is parked outside their home?

    A house that faces the street might be able to charge 3 or more kerb-parked vehicles overnight. All they need is a simple way to meter the electricity they sell.

  • "...it's just going to get easier and easier."

    In California, the State government has a policy of eliminating local control over zoning requirements for new construction. Parking is one of those. New projects in urban areas within a half-mile of "transit" (loosely defined) are not allowed to require parking at all (AB 2097), and parking reductions are being forced in a number of other areas. Since most people still need to drive, parking is moving onto the streets. As a consequence, for residents of many ne

    • I may have seen some places like this when I last visited California. People gave up on parking on the street and started driving up the curb to park on what little piece of front yard they had. I once looked up how big a parking spot must be in a parking lot, 10 feet by 20 feet. That's for having the space for parking someone's Ford F-250 with dual rear wheels, if you drive some "smart car" then it can take half that space to park. People would pave over what little piece of green grass they had for a

      Do you have proof of this? Not forcing developers to build parking is not the same as forced parking reductions.

      Since most people still need to drive, parking is moving onto the streets. As a consequence, for residents of many new multifamily buildings there simply will be no place at home for a charger.

  • Since most people probably use their car to go to work, it seems logical for "workplaces" to install chargers in their parking lot.
    That only works for corporations with a private parking lot of course.
    Still, it seems better than running an electric cable through a tree or over the sidewalk.

    Charging in the parking while shopping seems a good option too.

    • As a bonus, if solar really takes off, charging during the day when solar power is plentiful would be a good way to optimize loads.

      For that matter, for much of the country: Solar car ports. In the summer down south, it also helps keep your car cool, and reduces wear. In the north, during winter, it's areas you don't have to plow, or end up having to brush off and scrape your car regularly.

      Note: There are ways to deal with snow buildup.

    • Why are people smart enough to buy an EV so dumb that they still drive to work each day?

      • Smarts or lack thereof has nothing to do with it. The pandemic is over, so it's back to the grind. Most employers don't care if you have to get a ICE, BEV, or a Flintstone's car and propel it with your feet - you're going back to the office. It's your problem to solve or they'll give your job to someone else who does have a set of wheels.

    • it hasn't had 100 years behind it

      It'd be pretty silly to imagine that battery technology has stood still over the last century as there are plenty of uses for batteries besides being incorporated into EVs. As for the cars themselves, EVs were the original easy to operate "grocery getters" over a century ago. Catch was, you had to be relatively well off to afford one.

    The goal should not ONLY be to provide more charging options to renters, but instead to FIRST minimize the need for charging in the first place. What if an EV could be made so efficient that it could charge from Level 2 (240 VAC charging) as fast as most current vehicles charge from DCFC (DC Fast Charging)?

    Let's step back a bit. When efficient ICE vehicles started flooding the market in the 1970s, we called the previous vehicles "gas hogs". We need a similar flood in the EV market to make it clear that the vast majority of today's EVs are "watt hogs".

    Current technology lets the weight of an affordable EV be cut in half, which, along with drag optimizations, means the battery size can be cut roughly in half WITHOUT reducing vehicle performance. Where are the vehicles making use of this technology? Well, until now, they've mainly been in luxury cars, hypercars and Formula One cars. The BMW i3 made some great steps in this direction, but failed in some of the other areas needed for a successful vehicle.

    I'm aware of only ONE vehicle company that has been laser-focused on efficiency in every step of their design and manufacturing processes. Manufacturing? Yes: If your super-tech vehicle can't be built at huge scales, then it can't directly affect the market.

    As for the design, it all starts with the shape. At highway speeds, the majority of a vehicle's energy goes into moving air out of the way. If you can reduce that energy, you win. Today's designs are making incremental progress on that goal, but they ALL continue to tweak the same basic shapes used by decades of ICE vehicles, rather than try something truly different and vastly more efficient.

    It's also important to target this efficiency at the market segments needing it most. Today, that would be those who commute to work, the vast majority of whom drive solo, run errands during lunch or on the way home, and on average commute just 40 miles per day. What would it mean to HALVE the energy use of all daily commutes everywhere?

    First, it would mean optimizing the vehicle for 2 occupants, mainly to keep minimize both the payload weight and the interior volume. Not a family vehicle, but a commuting vehicle, preferably with enough cargo space for Costco runs, and perhaps to fit a bicycle inside. Why inside? Putting ANYTHING on the outside of a vehicle (ICE or EV) greatly increases drag (especially at highway speeds), which would be a double no-no for a high-efficiency EV. Two people with decent cargo space is a good target to aim for. Which means it would be the second vehicle for a family, but could be the only vehicle for pretty much everyone else.

    Fortunately, there is an extremely efficient vehicle shape that achieves the goals of optimal aerodynamics for two occupants with room for cargo. It's called the "Morelli Shape", created by Antonio Morelli and his students in the 1970s. This shape is not only extremely aerodynamic, but it is also inherently strong, meaning it doesn't need to be made out of metal to get the needed strength performance, but can instead be made from composites that can be affordably produced in large quantities. Think along the lines of the Tesla Gigapress, but for composites, and you'll get an idea of what can be accomplished.

    OK, let's see what we have so far. We have 2 occupants with cargo space. We have a sleek composite body. Next comes the chassis and drivetrain. Being a small and light vehicle, an aluminum chassis can easily provide plenty of strength to carry everything while needing less material than an otherwise equivalent steel vehicle. On a chassis cost basis, it'll be roughly the same strength and cost as a steel chassis, but be significantly lighter and easier to make.

    Next comes the drivetrain. Let's assume no new technology. Conventional NMC lithium batteries will be used with silicon carbide (SiC) inverters and permanent magnet motors (PMMs). Nothing new or flashy there. But to maximize usable interior volume, let's move the motors into the wheels. Yes, it will increase th

    • Modern EV drivetrains are already incredibly efficient. What isn't efficient is pushing air molecules out of your way at highway speeds.

  • 1% of all cars in Texas are EVs. 10% of the apartments available for rent on Apartments.com have EV charging. Seems to me there is plenty of EV charging available here. This is a problem the free market will take care of itself.
  • One easy option is to just extend the already existing electric infra. Streets already have lighting and it should be cost effective to just add a charger there. Charge a small fee to cover costs, maintenance and expansion
  • EV's are great if you have a consistent place to park with electric service for charging. Otherwise it's a pain.
    Avoid the pain, just drive an ICE or a hybrid.

  • To start we'd need to set some assumptions. Assume a fairly typical BEV, with average to low-end range to give some room for doubters, I'll pick the Chevy Bolt with an advertised range of 240 miles for this. Assume a typical weekday commute from the fine article of 30 to 40 miles.

    If someone has their Bolt start on Monday morning with a full charge then that over 5 days of driving 30 miles each day that means 150 miles off the battery by Friday evening. That gives them the weekend to find a place to recha

      "So long as the PHEV has something like 50 miles all electric range per charge then having access to a 120VAC charger at one's apartment means all electric driving excepting some event that prevents plugging in each night, which should be rare for most drivers."

      But having access to charging every night means a BEV is every bit as a good a solution, plus it doesn't have a tank of gas that sits unused and goes bad nor does it have an engine that requires regular maintenance. And the PHEV in this arrangement

      • But having access to charging every night means a BEV is every bit as a good a solution...

        Yep, absolutely, no argument from me. Knock yourself out. Whatever floats your boat.

        A PHEV is absolutely the wrong solution if you do not have access to nightly charging. A PHEV REQUIRES daily charging to exploit its capabilities, unlike an ICE, hybrid or BEV. Worst of all worlds, from an efficiency standpoint.

        That's, like, your opinion, man.

        If you don't like the PHEV option then that's fine. I laid out why many expect BEV prices to climb as adoption of BEVs and PHEVs increase, this will increase demand for limited resources and prices will rise as a result. The assumption is that people will have nightly access to charging, that's because they rent the property and have some kind of assurance of being able to plug in. If the

If not, I have to sit in some random place late at night for an hour, provided there is a free spot with a working charger. I don't hate the planet, but my family's safety is a more immediate concern. Modular battery swapping is the way to go I would think.

    • I drive to other people's houses or AirBNBs quite often. What are the odds all of them will have chargers?

      I'd say the chances are near 100% for some definition of "charger".

      Perhaps I recall incorrectly but I recall that the National Electrical Code requires an outdoor outlet on the front and rear of every house. That means if you can drive up to close enough to the house that it is safe and practical to run an electrical cord from the house to the parking space for your vehicle then you should be able to get 1400 watts or so of charging power to your EV. If your EV didn't come with a portable 120VAC/15A charg

  • I wonder what kind of solution we might have in our case. We are a small group of apartments with a common parking lot, all by owners. Is there some kind of plug we could install and share *and* not pay extra on the electricity ?
