The controller mainly comprises a microprocessor module, a power supply module, an analogue input module, a temperature acquiring module, a switching quantity input module, a switching quantity output module, a CAN interface module, a balancing module and a voltage acquiring module, wherein the analogue input module and the temperature acquiring module are respectively used for connecting signals to the microprocessor module; the power module is respectively connected with the switching quantity input module, the switching quantity output module, the CAN interface module, the balancing module, the voltage acquiring module; the switching quantity input module, the switching quantity output module, the CAN interface module, the balancing module and the voltage acquiring module are respectively connected with the microprocessor module through a first isolating circuits. According to the controller, the car can be controlled to normally run according to the battery management and the complete control; the fault can be determined; the charge and discharge states can be obtained; the charge can be balanced to ensure the consistency of batteries.

Description

technical field [0001] The invention relates to the field of battery management and vehicle control, in particular to an integrated controller for battery management and vehicle control, which is suitable for the integrated control system of battery management and vehicle control for short-distance sightseeing electric vehicles. Background technique [0002] Vehicle controller (VCU) and battery management system (BMS), as the core components of electric vehicles, have gradually attracted widespread attention. Due to the simple structure of short-distance sightseeing electric vehicles, VCU and BMS are used as separate control devices, which causes a waste of resources and increases the cost of the entire vehicle. [0003] The integration of BMS and VCU is completely conditional and necessary. The present invention provides a battery management integrated vehicle control integrated controller for this problem, which is used for the electronic control unit of short-distance sig...
