Bidirectional Charging & Energy Storage Solutions
The technology enables charging the batteries of electric vehicles and transferring the stored energy back to the stationary storage system in the building or to the grid when
In contrast to stationary storage and generation which must stay at a selected site, bidirectional EVs employed as mobile storage can be mobilized to a site prior to planned outages or arrive shortly after an unexpected power outage to supplement local generation or serve as an emergency reserve.
OEMs such as Volkswagen, BMW, Ford, Kia, and Hyundai already manufacture vehicles with DC bidirectional charging with the other OEMs expected to follow. On the other hand, the majority of manufacturers of chargers are also incorporating bidirectional chargers, especially “wall box” versions for residences or offices for vehicle fleets.
Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site's building infrastructure.
The typical case of using a bidirectional charger is the most beneficial in photovoltaic generation with connected battery storage. If we are able to power the vehicles at cheaper rates or use the car battery to store excess energy from a photovoltaic installation, this energy can be used at times when energy is more expensive.
