Can provide 24 hours of usage during a power outage.

BMW has used the Electric Vehicle Symposium & Exhibition 29 (EVS29) to introduce its new stationary energy storage system which uses a battery sourced from the i3.

Designed to help customers "more fully realize their commitment to sustainability," the system seamlessly integrates with charging stations and solar panels so owners can offset peak energy usage costs as well as have an emergency energy supply during power outages.

Speaking of the latter, BMW says daily household energy usage in the United States is between 15-30 kilowatt hours so the i3's battery should provide up to 24 hours of use during an outage.

The system also seeks to save customers money as it is equipped with a real-time energy monitoring system which can measure energy supply and demand.  The energy storage system can then calculate the optimal time to charge or discharge the battery.

Interestingly, the system can be expanded to incorporate used i3 batteries.  The company says the repurposed batteries will offer "many additional years of service" and will extend their useful life beyond the vehicle.

According to BMW of North America's Manager of Connected eMobility, Cliff Fietzek, "The remarkable advantage for BMW customers 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."
