Stationary storage provides the missing link between EVs and renewable energy. Tesla made it trendy, but other automakers, including Nissan, GM and Toyota, have been exploring the technology for some time.
Now BMW has announced a stationary storage solution that integrates its i3 vehicle battery.
BMW’s new system, announced at the recent Electric Vehicle Symposium & Exhibition in Montréal, uses BMW i3 high-voltage batteries, and can be expanded to incorporate second-life batteries as they become available on the market.
Developed in partnership with BECK Automation, the system includes a voltage converter and power electronics to manage the energy flow between renewable energy sources, a home interface, and the battery. It’s designed to be stored in a basement or garage, and has a capacity of 22 or 33 kWh, which BMW says should be sufficient to operate a variety of appliances and entertainment devices for up to 24 hours.
“The advantage in using BMW i3 batteries as a plug-and-play storage application is the ability to tap into an alternative resource for residential and commercial backup power, thus using renewable energy much more efficiently, and enabling additional revenues from the energy market,” said Manager of Connected eMobility Cliff Fietzek.
