Abstract

The invention discloses a control system integrating battery management and vehicle control functions, which is characterized in that it includes a main controller, a single acquisition slave controller, a high-voltage acquisition slave controller and an ISOSPI communication module, and the high-voltage acquisition slave controller The detector includes an information control module and several collection chambers, and each collection chamber includes a high-voltage collection module, a current collection module and a monitoring module. The present invention realizes the separation of high and low pressure from the structure of the whole vehicle; the position of the main controller is more selective in the layout of the whole vehicle; the backup and monitoring of several collection chambers make the data collection more stable.

Description

technical field [0001] The invention relates to the field of battery management and vehicle control, in particular to a control system integrating battery management and vehicle control functions. Background technique [0002] As the main development direction of future automobiles, new energy vehicles, especially pure electric vehicles, have been supported and encouraged by the state. With the strong support of national policies and the gradual breakthrough of key technologies, the prospect of the new energy automobile industry is good. Vehicle controller (VCU) and battery management system (BMS), as the core components of new energy vehicles, have gradually attracted widespread attention. VCU and BMS are used as separate control devices, which wastes resources and increases the cost of the vehicle. The integration of BMS and VCU is completely conditional and necessary. [0003] Based on the continuous upgrading and optimization of microprocessor technology, the current m...
