Saft is supplying a lithium-ion battery system to provide energy storage for one of the Solar Energy Grid Integration Systems (SEGIS) projects funded by the US Department of Energy (DOE). The design will incorporate energy storage and two-way communications between solar electrical systems and utilities.

Together with other highly-flexible controllable systems in the BMW Group production network, they will contribute to the stability of the public grid outside of the plant. Electricity generation from variable renewable electricity sources (VRE) such as wind and solar power has grown rapidly and is expected to continue to do so.

This project will demonstrate and test an electric vehicle’s ability to receive and respond to charge instructions based on the grid condition and the vehicle’s battery state. Using this aggregated data, the vehicle has the intelligence to charge to the level that is needed while factoring any current grid constraints.

BMW supplemented the smart charging of these vehicles with a solar-powered battery system made from BMW Group second-life EV batteries to support the grid during these demand response events, as necessary. If a customer does not opt-out, the vehicle charging can be shifted to meet the needs of the energy grid.

The service also seeks to return excess energy to the electrical grid, effectively converting EVs into publicly shared batteries. Logistically, this would help soften the blow for public utilities hoping to deliver energy when demand surges throughout the day.
