50kw CHAdeMO EV Charger, DC Fast Charger

Which EV connector should you use?

RUIHUA DC fast chargers are equipped with two connector types – CCS (Combined Charging System) and CHAdeMO (Japanese Fast Charging Standard) – corresponding to the interface The corresponding interfaces can be quickly identified by the blue-green (CCS) or blue-green + green double logo (CHAdeMO) on the charging post.

• CCS connector: Charging speeds up to 350kW for fast and efficient charging.
• CHAdeMO connector: Charging speeds of up to 50kW for compatible EV models.

Tip: Check with your vehicle’s manufacturer or owner’s manual to learn your electric vehicle’s charging capabilities. capabilities.

Charging efficiency recommendations:

• If the vehicle supports the CCS 350kW protocol, the CCS interface is preferred to reduce charging time;
• CHAdeMO is suitable for daily replenishment scenarios without the need for overcharging.

What happens during the charging process?

When you start charging, the vehicle’s Battery Management System (BMS) sends the charging station the current battery level (SOC value), e.g., “Current level is 30%.” The SOC information can be viewed in real time on the charging station screen or in the app (some models support dynamic updates).

Mid-charging phase: dynamic regulation of power

• Stage 0-80%: The battery is rapidly charged at the maximum allowable current (e.g. 100kW), and the charging rate (kW value) remains high during this stage.
• Stage 80%-100%: BMS actively reduces current and enters “trickle charge” mode, charging speed may drop by 50%-80%.

Temperature and Battery Health Management

If the temperature of the battery exceeds 45℃ or the voltage of a single unit is abnormal, the BMS will force power limitation to prioritize safety.

End of charge: recommendations for optimizing efficiency

Explanation of the “bulk charging” phenomenon

Vehicles typically significantly reduce charging power (e.g. from 150kW to 30kW) at SOC ≥ 80% to extend battery life, when the time gain of continued charging is low.
