Abstract

The invention discloses a power system of an electric car. The power system comprises a first power subsystem, a second power subsystem, a gearbox and a vehicle control unit, wherein the first power subsystem comprises a first power battery, a first battery managing device connected with the first power battery, a first motor controller connected with the first battery managing device, and a first motor connected with the first motor controller; the second power subsystem comprises a second power battery, a second battery managing device connected with the second power battery, a second motor controller connected with the second battery managing device, and a second motor connected with the second motor controller; the gearbox is respectively connected with the first motor and the second motor; the vehicle control unit is respectively connected with the first motor controller and the second motor controller and used for controlling the first power subsystem and the second power subsystem according to the working mode of the electric car. The power system is high in reliability and high in usability, and can ensure the safety of the electric car in running.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power system of the electric vehicle. Background technique [0002] With the shortage of energy, people pay more and more attention to new energy vehicles, and both pure electric vehicles and hybrid vehicles have been developed rapidly. [0003] Among them, pure electric vehicles use electric energy as energy, have the advantages of zero emission and no pollution, and have broad development prospects. In pure electric vehicles, the power battery, motor and vehicle control system are the three cores of pure electric vehicles, forming the architecture of the power system, which is of great significance for outputting vehicle driving force and ensuring vehicle driving safety. [0004] The main driving modes of existing electric vehicles include centralized drive, dual-motor independent drive (front-drive and rear-drive), four-motor and four-wheel independent drive, etc....
