Intelligent high-voltage power distribution manager

Abstract

The invention belongs to the field of electronic appliances and specifically relates to an intelligent high-voltage power distribution manager. The manager comprises a case, wherein a steering pump controller, an air compressor controller, a controller module, a fuse module, an intelligent control module, a DC / DC module, an interface module, a first pre-charging plate, a first capacitance plate, a second pre-charging plate and a second capacitance plate are disposed in the case; and the intelligent control module comprises a control mainboard, a communication module, a contact device control module, a touch point detection module, a voltage detection module, a current detection module, an environment detection module, a high-voltage interlocking module, a pre-charging detection / self-charging detection module, an insulation detection module, a firmware upgrade module, a system self-checking module, a power source isolation module and a historical failure code management module. The intelligent high-voltage power distribution manager provided by the invention has the advantages that multiple functions are integrated; data transmission can be achieved by the communication module; and external detection and data analysis can be conducted to a power source circuit system of an automobile easily.

Description

technical field [0001] The invention belongs to the field of electronic appliances, and in particular relates to an intelligent high-voltage power distribution manager. Background technique [0002] With the continuous improvement of human awareness of environmental protection, people are constantly looking for new energy sources that can replace oil. Among them, automobiles, as the main oil-consuming products, must be at the forefront of reform. In recent years, a large number of new energy vehicles have been launched on the market. In order to reduce the consumption of petroleum resources and protect the environment, new energy vehicles currently include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. [0003] Among them, a pure electric vehicle (Blade Electric Vehicles, BEV) is a vehicle that uses a single battery as an energy storage power source. . Its tech...
