■ EV Quick Charger Monitoring System
The EV Quick Charger Monitoring System is a device to monitor CHAdeMO quick chargers.
It has been developed specifically for EV quick charger manufacturers.

What is CHAdeMO?
CHAdeMO is a standard for a quick charging method for electric vehicles delivering up to 62.5 kW of high-voltage direct current (DC) via a special electrical connector. It is proposed as a global industry standard by CHAdeMo Association.
The CHAdeMo method achieves quick charge in a short time without damage to the battery. The Electronic control unit (ECU) of electric vehicle (EV) specifies the optimal charging current depending on the battery conditions. And an external charger delivers DC to an EV in accordance with the commands from the ECU.
