Are the charging ports of new energy vehicles the same?
1 Answers
New energy vehicles have different charging ports. Charging interface standards: Currently, charging interface standards have not achieved international unification. In China, the new national standard stipulates a unified charging interface standard for domestic new energy electric vehicles. There are two charging modes for electric vehicles in China: AC slow charging port and DC fast charging port. The slow charging port has 7-hole contacts, while the fast charging port has 9-hole contacts. Charging time: Slow charging is stable, safe, and takes a long time. Conventional charging piles are mostly slow charging with 220V household voltage, and civilian circuits can withstand the current and voltage requirements of slow charging. The slow charging time is usually 5 to 8 hours. Fast charging is quick and time-saving but has higher requirements. The fast charging method generally uses a special off-board DC charger for charging, and this type of charger is installed at fixed charging stations.
