EVI is a dual standard Supply Equipment Communication Controller (SECC) that includes all required signals for CCS controller (DIN 70121 and ISO 15118) and CHAdeMO (via Extension Board) to interface the EV Charging Controller (EVCC).

A powerful processor run the EV communications stack and/or other demanding applications (OCPP, EVSE master, etc)

EV communications stack can be pre-installed for CCS (DIN 70121 and ISO 15118) and CHAdeMO (0.9 to 1.2) or you can use your own stacks

In addition, EVI is capable of acting as a main controller for the charging process. It is readily compatible with:

  • EVSE supervisor (via CANopen bus)
  • Power Units for DC charging
    • MPU-R3 - Unidirectionnal Power Units 25kW
    • BMPU-R2 - Bidirectionnal Power Units 11kW

An optional extension board (EVIX) can add additional functions such as:

  • Addressing of 6 power units
  • CHAdeMO HW interface

Designed for smart grid applications, it features a modular conception capable of independent multi-charge point (CHAdeMO and CCS) and can control up to 14 MPU-25 power units in a high-power system up 350 kW.
