Charge Module E

Charge Module E is a compact charge module for AC and DC charging stations, real-time capable with a compact footprint and ready-to-use.

It adds DIN 70121 and ISO 15118 functionality to the EVSE side, as well as PWM generation and monitoring CP and PP states.

Real-Time Operating System

By seamlessly executing DIN70121 and ISO15118 communication in real-time, the module ensures efficient and reliable communication between the EV and your SECC.

Ready for bidirectional charging

Utilization of the latest communication protocols, making it fully prepared for ISO15118-20 for bidirectional charging and further features of the standard.
