DSC_9274BMW announced a program that puts batteries from BMW i3 electric vehicles to good use when they can no longer serve to power the i3 itself.

What the Bavarian automaker termed a “stationary energy storage system solution” was announced this week at the Electric Vehicle Symposium & Exhibition 29 in Montreal, Canada. It essentially gives the batteries a second life by repurposing them for home use.

The system can be charged using electricity generated from solar panels, electricity generated from wind, or, when off-peak rates are available, the power grid. It can serve as both a backup power supply as well as a temporary replacement for the power grid when energy costs are high.

“By combining an eco-friendly power supplier with the convenience of the battery storage system electrified by BMW i at home or at a small business, our customers will be able to store renewable electricity and then use it at an ideal time to augment energy from the grid during periods of higher pricing, effectively reducing energy bills,” the company said in a statement.

The system uses real-time energy readings to determine the optimal time to charge or discharge the system, thereby contributing to overall lower electric bills.
