3703 ChargeWorks EV Charger

Available as Single or Dual charger

Smart solutions for workplaces and other applications

EVSE is an established innovator in the electric vehicle battery charging industry with installations including Southern California Edison’s workplace charging locations, the largest smart grid/automated demand response deployment in the world.

For this application, SCE chose the 3703 ChargeWorks, EVSE’s competitively priced Level 2 and Level 1, 7.2 KW, single or dual wall- or pole-mounted electric car charger. Like all EVSE chargers, the 3703 can operate standalone or on a network, including Greenlots Open Charge Point Protocol (OCPP) to ensure universal access for all EV drivers – no member cards needed.

The model 3703 is capable of being controlled remotely to apply, reduce or disconnect power to the electric vehicle, and measures both voltage and current being supplied to the EV. Turn the charger on using simple On Activation, a mobile phone app or RFID card. The 3703 communicates directly with a Payment or Gateway Module, and five status lights clearly indicate the progress of the charging operation.

EVSE’s electric car charging units are smart-grid ready and now accept Automated Demand Response signals that control pricing and power during peak demand cycles. With a full line of EV charging stations, charger network management options including Open Charge Point Protocol (OCPP), usage reporting and payment options, and EV charger testers, our electric vehicle charging solutions easily adapt to your existing operations.
