Electric vehicle charging systems primarily connect the power grid and electric vehicles, and come into direct contact with consumers. Their safety and electromagnetic compatibility performance must comply with and meet strict standards and requirements to ensure that the charging system operates safely and stably, without causing harm to the human body, and without interfering with vehicles, power grids, and other equipment.
Main charging modes
• AC Charging:Electric vehicle charging stationsdirectly input AC power into the electric vehicle via a charging cable. The electric vehicle’s AC/DC converter then converts the AC power to DC power to charge the battery. Because theEV charging stationdoes not require a converter, charging time is longer, commonly known as “slow charging.”
• DC Charging: AC power is converted to DC power at the charging station, allowingdc fast charging stationsto use DC power to charge the battery. Due to high charging power and short charging time, it is commonly known as “fast charging.”
