Smart grids that track load and manage smart charging are already being introduced in many countries such as the US and Portugal. At least partial smart grid deployment by the end of the decade is expected to help reduce the need for grid upgrades caused by EV charging by reducing or avoiding peak load events. In the long run, with EVs accounting for more than a third of the total stock, smart grid deployment will be needed to avoid very large investment needs. In the long run, vehicle to grid (V2G) technologies will allow vehicles to be connected to smart chargers in order to help balance the system. EVs will support grid stability instead of being a bottleneck to network balancing requirements.
