The Munich-based automaker says that this is the first home energy storage system to use a complete vehicle battery, whereas something like Tesla Energy’s Powerwall isn’t built from a full Model S battery pack, for instance. The system is available in a 22 kWh or 33 kWh version, which would supply enough power to keep an average home operating for a full 24 hours, BMW says.
There’s no word on when or where the Beck systems will be available, but it’s likely that BMW will work directly with energy suppliers to make them available: in the US, it has worked with NextEra and PG&E for pilot programs in the past.
