Embodiment 2
[0057] Embodiment two: refer to figure 2 , the embodiment of the present invention discloses an explosion-proof automobile battery safety management method, comprising:
[0058] The BMS management system sends a handshake protocol to the charger, and the BMS management system communicates with the charger according to whether the charger receives the handshake protocol. Whether the charger receives the handshake protocol sent by the BMS management system determines whether the charger is managed by the BMS. The system can communicate, or the charger receives the corresponding identification code in the handshake protocol to judge that the charger can communicate with the BMS management system normally. By realizing whether the charger and the BMS management system communicate normally, it can ensure the normal data communication between the charger and the BMS management system, and prevent the entire system from being unable to operate due to one of the faults, so as to faci...

The invention discloses an explosion-proof automobile battery safety management method and system. The method comprises the steps that a BMS management system is in communication connection with a charger according to whether the charger receives a handshake protocol or not; the charger performs self-inspection to obtain a detection result and sends the detection result to a data monitoring platform; the BMS management system collects charging and discharging parameters; the BMS management system presets a charging and discharging parameter threshold value and compares the charging and discharging parameter threshold value with the charging and discharging parameter to obtain a charging and discharging comparison result and send the charging and discharging comparison result to the data monitoring platform; the data monitoring platform judges whether to send the detection result and the charging and discharging comparison result to the vehicle control unit or not; and the vehicle control unit controls the BMS management system and the battery to perform corresponding operation according to the detection result and the charging and discharging comparison result. If the charger performs self-inspection, the BMS management system detects whether the charging and discharging parameters exceed the preset charging and discharging parameter threshold, the data monitoring platform sends the result to the vehicle control unit, and the vehicle control unit performs corresponding operation according to the detection result and the charging and discharging comparison result, so that the safety of the battery is improved.
Description
technical field [0001] The invention relates to the technical field of explosion-proof automobiles, in particular to a battery safety management method and system for explosion-proof automobiles. Background technique [0002] In recent years, with the continuous development of motor and battery technology, electric vehicles have become the development trend of future vehicles. When the electric vehicle is running, the power battery pack is realized by mixing multiple single batteries, so the performance of the battery in terms of storage capacity, charge and discharge efficiency, charge and discharge current, charge and discharge voltage, and high temperature resistance affects the performance of the entire electric vehicle. . [0003] In the field of explosion-proof automobile technology, because the working environment of explosion-proof automobiles is in a dangerous working condition, the safety performance requirements for explosion-proof automobiles are extremely high....
