A fault prediction model corresponding to the battery number is constructed based on the number and cause of battery failures and the number and cause of battery maintenance. The fault prediction model is used to predict the probability and type of battery failure. A life prediction model corresponding to the battery number is constructed based on the number of battery uses, the number of charge and discharges, the number and cause of battery fixation, and the number and cause of battery maintenance. The life prediction model is used to predict the service life of the battery.

5. The integrated new energy vehicle battery swap station management network according to claim 4 is characterized by: The determination of whether the battery is faulty includes determining whether the battery is in a usable state according to the battery appearance image. When the determination result is "battery is ready to be used", the health state is evaluated. The health state is evaluated according to the health state score. The health state score is Through the function Obtain, where c1, c2, c3 and c4 are parameter indexes, and c1, c2, c3 and c4 are all greater than 1, and F is compared with the preset health score threshold Compare, when When the battery is available, When the battery is not available, When the battery is ready for use, and When the battery is maintained, it indicates that the battery is available. The judgment and evaluation results are transmitted to the battery maintenance unit and the charging management module.

6. The integrated new energy vehicle battery swap station management network according to claim 5 is characterized by: The battery maintenance unit is used to self-repair the battery through a battery swap station and / or repair it by professional maintenance personnel based on the battery status data and health status score.

7. The integrated new energy vehicle battery swap station management network according to claim 4 is characterized by: The optimization and scheduling unit includes an inventory optimization subunit, an intelligent scheduling subunit and a cross-regional management subunit. The inventory optimization subunit is used to manage the maintenance sequence of faulty batteries, the battery charging sequence and the recommended battery usage sequence. The intelligent scheduling subunit is used to combine the usage status of the batteries in the battery swap station, and intelligently mobilize the available batteries between the battery swap stations with sufficient available batteries and those with a shortage of available batteries, as well as intelligently mobilize the batteries between different battery swap stations based on the health status assessment results. The cross-regional management subunit is used to manage and track cross-regional batteries.

8. The integrated new energy vehicle battery swap station management network according to claim 5 is characterized by: The charging management module includes a charging setting unit and a charging and discharging maintenance unit. The charging and discharging maintenance unit is connected to the battery maintenance unit. The charging and discharging maintenance unit is used to perform self-repair by charging and discharging a battery that can be repaired by charging and discharging technology and / or to perform balanced power distribution on battery cells by balanced charging technology and / or to perform charging and discharging maintenance on batteries used in low frequency by charging and discharging cycle technology. The charging setting unit is used to set the charging current and voltage for energy replenishment of the battery and to predict the time required to complete charging.

9. The integrated new energy vehicle battery swap station management network according to claim 2 is characterized by: The safety management module includes a battery protection unit, a vehicle protection unit and a battery swap station protection unit. When the status monitoring module determines that the battery is in an unusable state through the battery appearance image and / or evaluates that the battery is unusable through the health status score, the battery protection unit will isolate and store the unusable battery and maintain the battery in a safe state. The vehicle protection unit is used to detect the safety state of the vehicle to be swapped based on the information of the vehicle to be swapped. The battery swap station protection unit is used to receive environmental data and charging equipment data to analyze the status of the battery swap station and the charging equipment in the battery swap station.

10. The integrated new energy vehicle battery swap station management network according to claim 3 is characterized by: The user usage layer includes an APP and / or mini-program and / or public account downloaded on a mobile device. The user usage layer is used to query the location of the battery swap station and the available battery inventory in the battery swap station, make battery recommendations based on the vehicle's compatible battery model and vehicle driving requirements, and pay for battery swap fees.
