A compact EV DC Wallbox charger


The compact wallbox EVC500 charger allows to charge electric vehicles (EV) by DC current via the CCS or CHAdeMO connectors.

The charger is available in two versions: 25 kW and 30 kW. Is equipped with an RFID reader and a 7” touch screen display. It supports the OCPP communication protocol version 1.6 and can be equipped with a GSM modem.

The charger optionally can work with energy storage systems as well as photovoltaic and wind installations. It also has the ability to implement the V2G standard.

Compact dimensions increase the versatility of its applications.



  • Fast DC charging of compatible electric vehicles

  • DC output: 25 kW or 30 kW
  • Two EV charging standards: CCS and CHAdeMO
  • Communication protocol: OCPP 1.6
  • Monitoring of station parameters is possible via built-in GSM modem (option)
  • Active rectifier ensures low of THDi current distortion factor
  • Possibility to implement the V2G standard
  • Adaptable to DC power supply from energy storage systems
  • High-contrast 7" touch panel
  • Compact dimensions
  • Product entirely developed and manufactured in Poland
  • Easy to install



The EVC500 charger is compatible with all types of electric vehicles that support the CCS and CHAdeMO charging standards. Compact dimensions and low weight make it stable for both commercial and private application properties. The charger is designed to wall or pole mounting.

EVC500 comes in three varieties:

  • AD/DC - for typical applications, mains power supply 3x400 V AC
  • AC/DC V2G - support for the V2G standard, in which the car's battery is treated as a mobile energy storage (CHAdeMO only)
  • DC/DC - cooperation with energy storage, photovoltaic and wind installations as well as use in mobile chargers for emergency charging of an electric car
