Terra AC W11’s OCPP 2.0 protocol enables integration with charge point management systems for energy reporting, access control, and load management without proprietary cloud lock-in. Dynamic power management feature reads a household energy meter signal and automatically reduces EV charging current when total home consumption approaches the grid connection limit, preventing fuse trips. RFID card reader controls charging access in multi-tenant buildings and commercial car parks, enabling billing per kWh via the connected CPMS. The MyCharger app lets the vehicle owner schedule charging during off-peak tariff windows and monitor session energy and cost. ABB Ability energy management integration connects Terra AC to building energy management systems for coordinated EV and HVAC load shifting.
