Users’ safety is paramount. Securing a safe operation by the EV user in a self-service environment is essential since fast charging utilizes high input power with high electric voltage.

CHAdeMO takes all possible measures for making the charging of as safe as possible and protect the user against any potential hazard while charging.

CHAdeMO has mandated the following safety principles to guarantee its safe operation.

• Communication is duplicated through the exclusive pilot signals and the data signals via CAN communication. These two communication routes can prevent false operation by defining action by AND condition, and stop order by OR condition.
• The interlocking hardware is structured so that the coupler is never disconnected from the inlet while charging, and no active electricity comes to the exposed terminal parts when disconnected.
• Electricity leakage is prevented through its unique electrical circuit design and the insulation checking procedure.
