The present invention provides a control method for a battery management system, including: setting a state machine for the battery management system, and the state machine periodically schedules the working state of the battery management system according to the working state of the state machine. If the state machine is in the current working state If the abnormal exit condition is not met, it is judged whether the current working state is consistent with the new working state to be jumped. If they are consistent, continue to execute the current working state; if not, jump to a new working state. If the state machine meets the abnormal exit condition in the current working state, exit the current working state of the state machine and jump to the new working state to be jumped. This solution periodically schedules the working status of the battery management system through the control module of the state machine according to the working status of the state machine. By setting the operations and work scheduling that can be performed under different working statuses, the battery management system can be clearly and quickly Control.
Description
technical field [0001] The invention relates to the field of battery management systems of electric vehicles, in particular to a control method of the battery management system. Background technique [0002] The battery management system (BATTERY MANAGEMENT SYSTEM, BMS) refers to the detection of basic information such as battery pack voltage, temperature, total voltage, and current through technical means, and realizes the state of charge (State of Charge, SOC) of the battery pack through specific algorithms ), and prevent the battery pack from overcharging and over-discharging through fault alarms, thereby prolonging the service life of the battery pack. Therefore, the battery management system has a great influence on the development of new energy vehicles. How to control the working status of the battery management system has also become a problem that major automakers have been exploring. [0003] The software modules of most current battery management systems usually...
