Distributed control electric power distribution system for multi-axle wheel-drive electric vehicle

Abstract

The invention belongs to the field of power distribution technologies for electric vehicles, and particularly relates to a distributed control electric power distribution system for a multi-axle wheel-drive electric vehicle. The distributed control electric power distribution system comprises a high-power box and a low-voltage storage battery, and is characterized by further comprising a plurality of axle unit power distribution boxes and a plurality of low-voltage chargers; the axle unit power distribution boxes are connected onto the high-power box in parallel, and the low-voltage chargers are connected onto the high-power box in parallel; the high-power box is connected with the low-voltage storage battery by high-safety fuses and a power master switch. The distributed control electric power distribution system has the advantages that various power supply circuits are provided with corresponding safety fuses, accordingly, devices of the vehicle can be effectively protected, and the safety of the vehicle can be improved; the problems of large quantities of motors of existing multi-axle wheel-drive vehicles, large quantities of controllers and difficulty in power distribution for the traditional structures can be solved by the aid of the distributed control electric power distribution system, and the distributed control electric power distribution system is good in reliability, safety and universality.

Description

technical field [0001] The invention belongs to the technical field of power distribution for electric vehicles, and in particular relates to a distributed control power distribution system for multi-axle wheel drive electric vehicles. Background technique [0002] Electric vehicles (including pure electric vehicles, hybrid electric vehicles and fuel electric vehicles), that is, vehicles that use electric energy to drive electric motors as power systems in whole or in part, have significant advantages such as high efficiency, energy saving, low noise, and zero emissions. It has incomparable advantages in energy saving. [0003] According to the location of the drive motor and the power transmission method, the electric vehicle drive system is usually divided into centralized single-motor drive, multi-motor drive, and electric wheel drive. For multi-axis wheel drive vehicles, due to the large number of motors and the large number of controllers, it is difficult to achieve po...
