Abstract

The invention provides an electric automobile high-voltage power distribution system which comprises a power supply module, a power transmission module and a load module. The power supply module comprises a battery unit, a switch unit and a pre-charging unit. The switch unit is electrically connected with the power transmission module and the load module. The pre-charging unit is electrically connected with the load module. The power transmission module comprises an interface unit and a conversion control unit. The interface unit is electrically connected with the load module and the switch unit. The conversion control unit is electrically connected with the load module. The load module comprises a first load unit, a second load unit and a third load unit. Through design of the switch unit, the interface unit and the conversion control unit, different load devices can be independently controlled, so that potential safety hazards caused by integrated control are prevented, the stabilityof the power distribution system is improved, and through design of the pre-charging unit, the situation that the load devices are damaged due to quick power supply is prevented, and the stability ofthe power distribution system is further improved.

Description

technical field [0001] The invention relates to the technical field of power distribution for automobiles, in particular to a high-voltage power distribution system for electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power battery and driven by a motor to drive the wheels. The power battery provides electric energy for the driving motor of the electric vehicle, and the electric motor converts the electric energy of the power battery into mechanical energy, and drives the wheels and working devices through the transmission or directly. In an electric vehicle, there are far more electrical devices than in conventional vehicles. Therefore, in addition to the low-voltage control system, there is also a high-voltage transmission system in the vehicle. The operating voltage of many components in electric vehicles is as high as hundreds of volts, and the current is as high as tens of amps, or even hundreds of a...
