High-voltage distribution box of pure electric commercial vehicle

Abstract

The invention relates to a high-voltage distribution box of a pure electric commercial vehicle. An electric-controlled high-voltage DC contactor is used as an input terminal; an electric-controlled air breaker is used as an output terminal; a high-voltage distribution controller is used for controlling the input and output of the high voltage according to instructions; and a special electricity meter for the electric vehicle is arranged for respectively displaying the total energy consumption of the vehicle, the energy consumption of a driving motor, the energy consumption of an air conditioner, the energy consumption of an electric-assisting steering oil pump, the energy consumption of an electric air compressor and the like. The high-voltage distribution box in the invention can automatically distribute the power to the entire electric vehicle, ensure the safety utilization of power, and easily update the control parameters of the entire vehicle.

Description

technical field [0001] The invention belongs to the field of electric vehicles and relates to a high-voltage distribution box in the electric vehicle. Background technique [0002] Pure electric vehicles are an important branch of the field of new energy vehicles. In recent years, with the support of the Chinese government, pure electric vehicles have been greatly developed. The high-voltage distribution box is an important part of the control system of the pure electric vehicle. It is the interface between the energy storage device and the electrical equipment of the pure electric vehicle. It is the core of the management of the high-voltage power consumption of the whole vehicle. and safe use of electricity play a key role. However, there is currently no high-voltage distribution box specially designed for pure electric vehicles. The existing distribution boxes are difficult to ensure the safe and efficient power consumption of electric vehicles, let alone update the cont...
