India's only completely indigenous EV/EVSE PLC — and its controller.
The entire powerline-communication stack — DIN 70121, ISO 15118-2 / -20, SLAC, Plug & Charge — written in-house, paired with a quad-core Linux supervisory Controller running OCPP 1.6J / 2.0.1 and scaling to megawatt sites. Our own battle-tested, platform-independent V2G Core runs through it all.
JP-ControllerA split-brain design — controller plus indigenous PLC.
The Controller (host) manages DC power modules, metering, OCPP, HMI, RFID, logs and platform functions. The PLC board — India's only completely indigenous EV/EVSE PLC — handles IEC 61851 CP/PWM, ISO 15118 / DIN 70121 high-level comms, Plug & Charge and the contactor / safety chain with deterministic safe-stop logic. V2G-ready by design.
