Europe Is Getting a Network of 'Ultra-Fast, High-Powered' EV Chargers (theverge.com) 72

Posted by BeauHD from the it-takes-two-to-tango dept.
An anonymous reader quotes a report from The Verge: BMW Group, Daimler AG, Ford, and Volkswagen have entered into a partnership to create a network of high-speed charging stations for electric vehicles across Europe. The new chargers will be capable of doling out up to 350 kW of power -- which would make them almost three times as powerful as Tesla's Supercharging stations. The result will be "the highest-powered charging network in Europe," according to a statement released by the manufacturers. The automakers say that construction will begin in 2017 with "about 400 sites" being targeted, and that the network will have "thousands of high-powered charging points" available by 2020. Those four major conglomerates will be "equal partners" in the joint venture, but according to the statement they are encouraging other manufacturers to "participate in the network." One of the reasons for bothering to call on other automakers to hook into this system is because there's a standards war happening with fast charging networks. The charging network announced today will use the Combined Charging System (CCS) technology, which is what that most major automakers already use for their EVs. But Nissan, Toyota, and Honda are notable holdouts from CCS, because many of their EVs and plug-in hybrids use a competing standard known as CHAdeMO.

    Why do tech companies even do this? Why can't everyone just agree on a standard and stick with it from the start instead of having a war that means us consumers who buy gear from the wrong side will suffer. No doubt there will be large dongle adapters between charging standards, but I bet an adapter that can handle 100+ kilowatts is pretty darn expensive.

    I mean, the basic requirements for a plug are that it be mechanically sound and inexpensive to manufacture. It ought to have several conductor pins, filled in by order of amperage, so a 2 pin plug is 50 amp and a 4 pin plug is 100 amp and so on. The plugs for lower amperage would be the same size plastic mold, just missing the conductors for higher amperage. Not that hard to get right. It needs a data pin to do handshaking with the destination.

    It's not worth fighting a war to get royalties, every electric car manufacturer has an incentive to use the standard used by the majority so everyone's vehicles can charge more places.

        The other reason is no one is an expert until it's actually tried. Each "standard" has their own pluses and minuses, each of which wasn't readily apparent when it was created.

        That, and most standards organizations are all about patent swapping - I'll get your patent into the standard, if you'll get my patent in the standard. They're less about pushing technology forward and more about how diplomatic you can be during negotiations.

        Indeed, when a new standard is called for, usually there's a call to industry to propose their ideas and implementations and if there's only one working one out there, it will likely be the standard regardless if there's a better version in R&D right now.

      We need new standards when the old standards are insufficient. Tesla developed their own standard because there wasn't anything else fast enough (CHAdeMO is slower). CCS is designed to work as an extension to the standard J1772 level-2 (240V) chargers, and I think it's faster.

      The good news is that it should be possible to create adaptors. Tesla already has CHAdeMO adaptors, and I suspect CSS adaptors will be available soon. I would suspect that CHAdeMO and CSS will have adaptors for each other at some point. For the short term, it means carrying around extra cables, but eventually it will be all sorted out.

      Building a high power charger is not easy. The connector has to be rugged enough to survive day to day use, waterproof, safe in the rain, and deliver tens or hundreds of kilowatts. When you get up to the 100kW range you start to need liquid cooling for the cable.

      The good news is that most of the work is generating the high current DC power needed, so a single charger can easily have both CHAdeMO and CCS connectors available. The ones Nissan paid for in the UK are like that.

      I have an idea for a few things you missed out. But I don't want to post them here or we'll end up with 2 different standards again.

      • Wouldn't mind, I'm sure they are way more complex. I was just thinking an all in one plug needs to support earlier cars with slower max charging rates and the cord/plug needs to be cheaper, saving you the weight and expense of several extra kilograms of copper that the high amperage cord would need.

        • Indeed but the cords already come with the cars. There's no reason even with the existing standards that a cord will be larger than what a car would need to charge.

          This isn't a standards war, it's stock standard (pun intended) evolution. The prior standard is based on a design from 1993 with CAN bus signalling. There's 2 major standards at the moment (3 if you count Tesla's). Some of them are largely compatible with the ability to adapt between the DC ones anyway. But none of them have the requirements need

          • ? I'm talking about the connector. The connector needs to support different charging rates by an array of parallel pins so slower cords can just have an empty connector for all but the minimum set of current carrying pins.

            • Right. But the metal inside the connector is an incredibly tiny portion of the cost of the connector, you're not saving much. Actually the opposite. Depending on the connector (if it's moulded around the pins like many such connectors are to improve their sturdiness) it may actually reduce the economies of scale. Also lots of parallel connectors have lower power capacity than single connectors at the correct size. Same reason why you can put 3 identical cables on a small cable tray, but when you put 10 next

              • Yeah that would be easier, wouldn't it. Requiring both high and low current chargers and high and low current cables to populate every conductor means the low current cables would have a long lifespan from having more total conductors than they need. So in your version, you'd make the low current cable have a thinner cable portion while the high current cable would have much thicker copper wires and even tubes for coolant water? (the coolant would be supplied by the charger)

      It looks like the new 350kW stations will be 800 or 1000 volts at 350 amps.
      However, the current CCS cable and connector is only good for 200 amps so something will need to change.
      The utilities are also likely to have something to say about people plugging and unplugging 350 kW loads for short periods of time.
      Current Tesla Superchargers usually have a 500 kW transformer to serve six or eight charging stations (which are paired to share power). This could accommodate one or two (at reduced power) of the new stations.

      Dongles tend to be a lot heavier and difficult to manage when dealing with that amount of power. There is an adapter for Tesla to use ChaDeMo and it's fairly large, in part due to the huge size of the ChaDeMo connector compared to the Tesla connector. There is also the problem where this charging standard uses a much higher voltage than CCS, ChaDeMo or Tesla standards which all use a similar voltage range.

      These new chargers have more than twice the capacity of a Tesla supercharger. Battery charge rates are improving. A vehicle with a 200 mile range which can recharge to 80% in 10 minutes is even more viable than a vehicle with a 300 mile range which can do it in 30, and that's coming but it's a few years off, yet these chargers will already accommodate that.
