The smart battery swap cabinet aims to solve the slow charging and charging safety problems of low-speed electric vehicle batteries, and solve the transportation capacity problem for high-frequency users of electric vehicles such as food delivery drivers. It can communicate with the battery in real time throughout the whole process, can use fast charging solutions for the battery, monitor the changes in current, voltage, power and surrounding environment during charging, and use the smart battery charging curve control algorithm to control the charging current to ensure the safety of charging input current. The battery swap cabinet also monitors BMS faults and whether there are abnormalities in the environment in real time. Once an abnormal phenomenon or safety hazard occurs, it will immediately stop charging and notify the operation and maintenance management personnel to deal with it in time, which can effectively prevent the occurrence of safety hazards during charging.
