![]() ![]() The size of a light-duty EV battery (approximately 15–100 kWh) makes individual bidirectional units ideal for smaller applications like individual buildings, where they can optimize the use of PV and replace or supplement emergency diesel generators. ![]() 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. V2B and V2G power solutions can complement solar photovoltaic (PV) arrays and other distributed energy resources (DERs), or supplement diesel generators as backup power. A bidirectional EV can receive energy (charge) from electric vehicle supply equipment (EVSE) and provide energy to an external load (discharge) when it is paired with a similarly capable EVSE.īidirectional vehicles can provide backup power to buildings or specific loads, sometimes as part of a microgrid, through vehicle to building (V2B) charging, or provide power to the grid through vehicle to grid (V2G) charging. Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site’s building infrastructure. ![]()
