Using managed charging to mitigate EV peak load 

EV-EVSE-Mercury architecture

The rapid adoption of EVs has the potential to create both challenges and opportunities for utilities. An EV with a daily commuting distance of 25 miles requires as little as 7 to as much as 18 kWh of electricity to recharge each day. Unlike the infrastructure that has evolved to refuel vehicles with internal combustion engines, which relies on commercial gas stations, it is likely that the majority of EV charging will take place at home, where many consumers will install a Level 2 EV charging system that consumes 7 kW when charging. While this represents a significant energy sales opportunity for utilities serving those customers, it also poses formidable capacity and at-scale stability risks to the grid.
