Abstract

The invention discloses a charging gun locking detection device and method, a communication controller and an electric automobile. According to the device, the first end of a first resistor is connected with a power source, and the second end of the first resistor is grounded through a second resistor; the first end of a grounding resistor is connected with the driving end of a motor, and the second end of the grounding resistor is grounded; the motor is used for driving a locking mechanism to lock a charging gun; and a microprocessor judges whether the charging gun is locked or not according to the voltage at the second end of the first resistor. The first resistor and the second resistor form a voltage dividing circuit; and when a switch in a locking device is closed, the second resistor is directly in a short circuit or another resistor is available to be connected with the second resistor in parallel, and then a new voltage dividing circuit is formed. Therefore, the microprocessor of the detection device can detect the state of the switch in the locking device, and whether the charging gun is locked or not is judged according to the state of the switch. The detection device has universality and can be suitable for various locking devices. The device has universality and is convenient to install and repair and convenient to maintain and upgrade in a later period.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a charging gun locking detection device, method, communication controller and electric vehicles. Background technique [0002] With the shortage of energy and environmental pollution, electric vehicles are more and more accepted by the public. Electric vehicles rely on power batteries to provide driving force. When the power battery is dead, it needs to be charged. At present, the charging gun is inserted into the car charging stand to charge the power battery. [0003] Due to the heavy weight of the charging gun, it needs to be locked after being inserted into the charging stand to prevent it from falling off. After the charging gun is inserted into the charging stand, it is necessary to check whether the charging gun is locked. [0004] However, at present, the charging gun locking devices designed by various manufacturers of electric vehicles are not uniform. The...
