High-voltage connectors for new energy vehicles

New energy vehicle high-voltage circuits put new requirements on connectors. The circuit voltage in a conventional car is about 14V, and the connecting circuit uses a low-voltage connector, and the circuit is also used in the control system of a new energy vehicle (electric vehicle). 

The power system voltage of the new energy vehicle can reach 400-600V, the low-voltage connector can not meet the requirements, and the high-voltage connecting device is needed; the more insertion times, high temperature and severe vibration in use puts more stringent requirements on the performance of the connector. At the same time, in order to improve the charging efficiency and motor power, the operating current and voltage of new energy vehicles continue to increase, and the requirements for the working voltage and current of the connectors are also increasing.

In new energy systems, high-voltage connectors are used in a wide range of applications to connect charging infrastructure (charging stations and charging stations) with electric vehicles and internal components of electric vehicles. Variety of product categories: The charging gun that connects the charging pile to the car, the battery-replaceable power-changing connector, and various types of vehicle-mounted connectors.

New energy charging and replacing systems require special connection devices. The new energy vehicle power battery can only accept DC charging, and the AC power on the power grid needs to be converted by the charging pile before it can be used. Charging pile, in the industry standard, its terminology is “non-vehicle charger”, its function is to convert the alternating current in the power grid into a specified current, and connect with the electric vehicle through the cable connection assembly and the charging gun, which is the power of the electric vehicle. The battery provides electrical energy. 

The AC charging pile outputs AC power. The built-in “Car charger” of the electric vehicle converts the AC power into DC power to charge the battery. Due to the simple equipment, the household wall-mounted charging pile is usually an AC charging pile; and the DC charging pile can exchange the AC power of the power grid. Converted to DC power, directly charge the battery, charging power is large, can achieve fast charging, shopping mall parking lot, charging station is usually DC charging pile, in order to achieve efficient use of space, each charging pile is usually equipped with two or more Charging connection assembly.

The high-voltage connectors are frequently used in new energy vehicles. The high-voltage harness is the neural network of the high-voltage system of the new energy vehicle. It is connected with the high-voltage connector to form a high-voltage connection system, and the high-voltage device and the electric vehicle high-voltage box (PDU) are connected to form a high-voltage system. The high-voltage direct current output from the  battery pack is distributed by the electric vehicle high-voltage distribution box, and the steering motor and the power motor are driven by the motor controller inverter or the inverter, and simultaneously, through the DC voltage converter or the inverter, to the air-conditioning compressor. Water heater PTC charger, wind heating PTC and components for power supply.
