This disclosure discusses systems, methods, and techniques for charging a plurality of electric vehicles (EVs). In one aspect, a system may include a plurality of electric vehicle supply equipment (EVSE), and the EVSEs are coupled between a power grid and the EVs. The system may also include a plurality of power meters, and a respective power meter may measure an amount of power received from a respective EV. The system may determine an instance of communication connectivity between the system and the EVs. After establishing communication, the system may communicate with the EVs using any communication protocol and/or standard. The communication may then enable the system to receive EV characteristics, for example, a state of charge of each EV. Based on the EV characteristics, the system may then determine power conversion efficiencies of each EVSE. By so doing, the system can determine power losses associated with each EVSE. Finally, based on the EV characteristics, the power losses associated with each EVSE, and/or a power availability, for example, from the power grid, the system may balance power loads associated with the EVSEs and/or the EVs.
