The invention discloses an emergency stop control device for an AC charging pile, comprising an emergency stop switch, an emergency stop drive circuit, a shunt tripping coil relay, and an air switch; the emergency stop switch is connected to a control terminal of the emergency stop drive circuit, The driving end of the emergency stop drive circuit is connected to the shunt tripping coil relay, and the air switch is connected to the power line of the AC charging pile through the normally open contact of the shunt tripping coil relay; the AC charging pile The AC power input switch controlled by the shunt coil in the air switch is provided on the power line, and the switch knife of the AC power input switch is connected with the gate of the normally closed switch of the shunt coil in the air switch through the linkage mechanism. Knife connection. The invention can quickly cut off the AC input power through the emergency stop switch when an emergency occurs, avoiding the risk of electric shock for users and enhancing the safety of charging. The invention also provides an AC charging pile.
Description
Technical field [0001] The present invention relates to the field of electric vehicle charging technology, and more particularly to an inter-AC charging pile emergency stop control device and an AC charging pile. Background technique [0002] As people pay attention to green travel, electric vehicles are increasingly popular, and the corresponding charging equipment and other charging equipment are also increasing, and the charging safety and reliability of these charging equipment are also received. [0003] However, the current partial charging pile products did not design an emergency stop protection function, and the AC power supply was unable to emerge in an emergency, causing an electric shock risk in the user side. Inventive content [0004] The present invention provides an alternating current charging pile emergency stop control device and an AC charging pile to solve the technical problem of lack of emergency stop protection functions in existing charging piles. The pr...
