DC Charger Building ＥＶ Communication controller

Communication Power converter Cable & Connector control Traction battery

AC Power

Quick Charger Vehicle Signal the start-of-charging setup (‘d1’ on) Start CAN communication (‘f’ on)

Transmit battery parameters: Target charge voltage, Compatibility check battery capacity, maximum charging time etc.

Transmit charger parameters: Available output Compatibility check voltage/current, Error thresholds etc.

Receive charging permission signal (‘j‘ on) Signal the completion of vehicle setup (‘k’ on)

Lock the connector and perform insulation test Receive charging start signal (‘g’ on) Signal the completion of charger setup (‘d2’ on) Turn on EV main relays

Charging current control Calculate optimal current based on battery condition Control output current Transmit current order value (every 100msec) Monitor charging errors and charging timer Monitor supplied current and error

Battery energy has reached the threshold value

Terminate outputting current Signal the completion of battery charging

Receive charging termination signal (‘j’ off) Confirm that DC current on main circuit is below 5A Terminate charging session (‘d1’, ‘d2’ off) Turn off EV main relays Unlock the connector Terminate charging session (‘k’ off)
