Abstract

The invention discloses a high-performance power distribution circuit of an electric vehicle. The circuit comprises a power switch tube and a functional circuit connected with the power switch tube, wherein the input end of the power switch tube is connected with a DCDC converter of the electric vehicle, the output end of the power switch tube is connected with vehicle low-voltage equipment, a DCDC power supply is connected to the vehicle low-voltage equipment through the power distribution circuit to provide energy for the vehicle low-voltage equipment, and the functional circuit is used forprotecting the power switch tube. When power distribution is carried out on the electric vehicle, the operation is simple, and the performance is stronger. According to the invention, a voltage detection function, a current detection function, an overload protection function, an overcurrent limiting function and a short-circuit protection function can be realized; according to the electric vehiclepower distribution circuit, the functions are highly integrated, the design difficulty of the circuit is reduced, a quick response protection mode is adopted, and the product performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a high-performance power distribution circuit for electric vehicles. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Conventional electric vehicle power distribution circuits need to design relays, fuses, current detection devices, and voltage detection devices. There are many devices and unstable performance. Contents of the invention [0003] The purpose of the present invention is to provide a high-performance power distribution circuit for electric vehicles, so as to solve the technical problems of traditional power circuit design with many devices and unstable performance. [0004] I...
