宝马未来实验室探秘

电池棚

    在停车场的一个棚子里，宝马保存了从电动汽车上拆下来的锂离子电池。登普斯特说，用这些电池可以开展许多具有潜力的项目。有朝一日，这些项目可以根据一些因素，包括我们未来购买电动汽车的方式，来支持一个废弃锂离子电池的市场。

如今，电池棚为宝马的一些汽车充电器提供能源。通常情况下，山景城的标准电力负荷是30千瓦，而一个快速充电器需要50千瓦时的电力。登普斯特说：“所以如果我们能利用这些电池，而不是仅仅通过电网充电，就能创造更有效益的系统。我们目前正在研究这个课题。”

The battery shed

    In a shed in the parking lot, BMW keeps lithium-ion batteries after they've been removed from electric cars. There are all kinds of potential projects for these batteries, Dempster says. Someday, the industry could support an end-of-life lithium-ion battery market, depending on several factors, including the way we finance electric cars in the future.

Right now, the shed of batteries provides energy to some of the car chargers at BMW. Usually, a fast charger accounts for 50 kilowatt-hours of demand to the Mountain View facility's typical 30 kW load, Dempster says. "So if we can use the battery instead of just charging from the grid, it's a much more cost-effective system. We're investigating that."
