SECC - Supply Equipment Communication Controller

EVIS511 Topview

EVI is a standard Supply Equipment Communication Controller (SECC) that manages CCS controller (DIN 70121 and ISO 15118-2 and ISO 15118-20) and CHAdeMO (via an Extension Board) to interface the EVs.

A powerful processor runs the EV communication stack, an IMD (Insulation Monitoring Device), voltage measurement, plus other demanding applications (OCPP, EVSE master, etc.).

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

  • MPU - Unidirectional Power Units
  • BMPU - Bidirectional Power Units

An optional extension board (EVIX) is available if you want to implement additional functions, such as:

  • Addressing >6 Power Units (up to 14 MPU-R3 or 16 BMPU-R2) ;
  • CHAdeMO interface ;
  • IOs and additional peripherals: analog inputs, 4G access, PWM outputs, LEDs, extra CAN bus.

Designed for smart grid applications, its modular conception makes it capable of controlling multiple independent charge points (CHAdeMO & CCS), and up to 14 MPU-R3 Power Units in a high-power system of 350 kW.
