Embodiment Construction

[0024] The present invention considers five independent controllers of the high-voltage system, and has disadvantages such as long R&D and debugging period, high R&D and batch costs, scattered controller strategies, and large quality ratio. According to the functional characteristics of the high-voltage system of electric vehicles. Invented a new energy vehicle power system integration scheme. To integrate five independent high-voltage control systems into a single controller, this solution uses multi-core control chips to reduce software complexity.

[0025] Such as figure 1 As shown, the new energy vehicle power system controller 2 is composed of a control board 11 , a drive board 10 , a high voltage board 9 , a signal control line 13 , a drive control line 12 , and an interactive wiring harness 14 .

[0026] Among them, the control board 11 is composed of a processing chip, which mainly realizes driver demand analysis, vehicle torque drive, vehicle high-voltage power-on / o...

Abstract

A power system of a new energy vehicle is disclosed, The system is provided with a power system controller, the power system controller comprises a control board integrated in the same housing, A drive plate and a high-pressure plate are formed, the control board outputs a control signal to the driving board through a signal control line, The driving plate outputs a driving signal to a high-pressure plate through a driving control line, the high-pressure plate obtains a feedback signal of the connector and transmits the feedback signal to the driving plate through the driving control line, andthe driving plate transmits the feedback signal to the control plate through the signal control line. The invention simplifies the structure of the high-voltage system of the new energy electric vehicle, effectively saves the high-voltage wiring harness, the controller shell, the controller internal hardware circuit and the chip, etc., and greatly reduces the cost of the new energy electric vehicle. In the whole vehicle research and development, the electric vehicle research and development debugging cycle is shortened, and the research and development cost is reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicles, including various electric vehicles, various hybrid vehicles, vinyl vehicles and vinyl vehicles, and the like. It specifically relates to a new power system of a new energy vehicle. Background technique [0002] At present, the existing new energy electric vehicles are composed of a battery and an electric drive system. The battery of the electric vehicle is charged through the mains power, and the electric energy is stored in the battery. When the vehicle is running, the whole vehicle is driven by the electric drive system through the conversion of electrical energy into mechanical energy.
