Problems solved by technology

The specific heat capacity of the coolant is larger than that of the air. The circulation of the coolant can quickly dissipate heat from the on-board charger, and the cooling device is integrated with the on-board charger, that is, the cooling device is installed inside the on-board charger to effectively save space. During the use of the charger, the connection of the plug will often cause poor contact due to accidental touch or other reasons. The poor contact will cause damage to the vehicle battery and the circuit. At the same time, the charger can only charge and cannot discharge. It is also difficult to switch between charging and discharging when powered by electrical appliances

Abstract

The invention discloses a bidirectional vehicle-mounted charging system with a poor contact prevention function and relates to the technical field of vehicle charging. The system comprises a plug connected with a charging pile and a vehicle-mounted socket hinged with a dust cover, one side of the vehicle-mounted socket is connected with a connecting device, and the vehicle-mounted socket and the connecting device are mounted in a vehicle. A charging device and a discharging device are installed in the connecting device, the vehicle-mounted socket is in contact with the plug for charging, the vehicle-mounted socket is not in contact with the plug during discharging, and a conversion device is arranged in the connecting device and used for conversion between charging and discharging. The plug is provided with the electromagnetic limiting assembly, it can be guaranteed that the plug and the vehicle-mounted socket always keep tight contact in the power-on period, the plug is further provided with the threaded hole and the bolt, loosening is further prevented through the threaded hole and the bolt in the plug-in connection process of the plug and the vehicle-mounted socket, and the situation of poor contact is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle charging, in particular to a bidirectional charging vehicle charging system with the function of preventing poor contact. Background technique [0002] The electric vehicle charger is a device specially designed for charging the battery of an electric vehicle. It is a power conversion device with specific functions used when charging the battery. The function of the charging pile is similar to that of the fuel dispenser in the gas station, which can On the ground or walls, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations, it can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide tw...
