Electric accessory integration control system for pure electric passenger vehicle

Abstract

The invention discloses an electric accessory integration control system for a pure electric passenger vehicle. The electric accessory integration control system comprises a birotor motor, an electric accessory system, a power supplying system and a control system, wherein the birotor motor is respectively electrically connected with the electric accessory, the power supplying system and the control system. With the above method, a steering power-assisting oil pump, a blast pump and a compressor can be integrated by the use of the electric accessory integration control system, so the three accessories can share the same power source; the electric accessory integration control system size and weight can be obviously reduced, so a series of power driving components and corresponding control components can be reduced; cost of the electric accessory integral control system can be reduced and energy conversion between the driving component and the electric accessory can be reduced; energy conversion efficiency of the electric accessory integral control system can be improved; and the electric accessory integration control system for the pure electric passenger vehicle has wide market prospect and can be widely popularized.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electrical accessory integrated control system for pure electric passenger vehicles. Background technique [0002] Nowadays, the requirements for vehicle lightweight and electric unit integration are getting higher and higher, especially for new energy vehicles. The electrical accessories of existing pure electric vehicles include air pumps, power steering oil pumps and compressors. Pure electric vehicles have canceled traditional engines, and their electrical accessories require additional power sources. Due to the limited overall space of pure electric vehicles, too much space occupied by electrical accessories will inevitably lead to a reduction in the space available for personnel; under current technical conditions, the air pump, power steering oil pump and compressor all use independent power The source requires three motors to drive and the corresponding mo...

Due to the limited overall space of pure electric vehicles, too much space occupied by electrical accessories will inevitably lead to a reduction in the space available for personnel; under current technical conditions, the air pump, power steering oil pump and compressor all use independent power The source requires three motors to drive and the corresponding motor controller to control, resulting in an increase in the cost of electrical accessories and low energy conversion efficiency

[0003] Invention patent CN201410849104.X proposes an integrated system of air pump and steering oil pump for new energy vehicles. This invention patent proposes an integration scheme of air pump and power steering oil pump, but does not integrate electric air conditioner

Because the rated speed of the air pump and the power steering oil pump are close, the same motor can be used to drive, but the speed of the motor driving the air conditioner compressor is much higher than the rated speed of the power steering oil pump, so the air pump, power steering oil pump and power steering oil pump are integrated at the same time. Compressors are a problem
