EU Project Aims To Switch Data Centers To Second Hand Car Batteries

judgecorp writes "A €2.9 million European Commission funded project aims to make data centers more efficient, and one of its ideas is to use second hand car batteries to power data centers. The GreenDataNet consortium includes Nissan, which predicts a glut of still-usable second hand car batteries in around 15 years, when the cars start to wear out. Gathered into large units, these could store enough power to help with the big problem of the electricity grid — the mismatch between local renewable generation cycles and the peaks of demand for power."

Re:Why old?

Can someone explain why old car batteries are better suited than new ones?

Yes.

Is it perhaps that old car batteries just cannot produce the huge peak required to start the engine but that energy storage and extraction works fine at lower currents? And that therefore old batteries perform adequately at lower cost?

You.

This has been discussed previously with regards to the aging fleet of electric automobiles and their need to be replaced while still useful.

Perhaps you're thinking of a posting forum in which not reading the article is frowned upon?
