Problems solved by technology

[0003] However, the existing BMS system generally starts operation by timing wake-up after the terminal is powered on. Only after the BMS system wakes up can it monitor and alarm the voltage, temperature, insulation and other safety indicators of the battery unit.
Since the BMS system monitors and alarms the battery unit regularly, the real-time monitoring of the battery unit is poor, and it is prone to the risk of battery abnormalities and missed reports

Abstract

The invention discloses a BMS self-adaptive pressure awakening method and device and a storage medium. According to the method, a current atmospheric pressure value is monitored; obtaining a trigger pressure threshold value according to the atmospheric pressure value, the standard atmospheric pressure value and the trigger pressure threshold value; updating a trigger pressure threshold value currently stored by the air pressure monitoring unit; and the air pressure monitoring unit judges whether to wake up the battery management main control unit or not according to the updated trigger pressure threshold value and the current pressure value in the battery pack detected in real time, so that the awakened battery management main control unit performs battery pack abnormality monitoring on the single batteries in the battery pack. By considering the atmospheric pressure value of the current position, the BMS is accurately awakened through the self-adaptive pressure signal, so that the monitoring real-time performance of the battery unit is improved, and the risk of abnormal missed reporting of the battery is avoided.

Description

technical field [0001] The invention belongs to the technical field of battery management systems, and in particular relates to a BMS self-adaptive pressure wake-up method, device and storage medium. Background technique [0002] BMS (Battery Management System, battery management system) is the link between the battery and the user. It is mainly used to control and manage the battery, improve the utilization rate of the battery, and prevent the battery from overcharging and over-discharging. It can be applied to electric vehicles, battery cars, Robots, drones and other fields. [0003] However, the existing BMS system generally starts operation by timing wake-up after the terminal is powered on. Only after the BMS system wakes up can it monitor and alarm the safety indicators such as the voltage, temperature, and insulation of the battery unit. Since the BMS system monitors and alarms the battery unit regularly, the real-time monitoring of the battery unit is poor, and the ...
