ISOLATED BIDIRECTIONAL CONSTANT-CURRENT MAINTENANCE SYSTEM BASED ON POWER SUPPLY SOURCE OF SHARED DEVICE

摘要

An isolated bidirectional constant-current maintenance system based on a power supply source of a shared device, comprising a power supply source, an electronic switch (K1), a current sensor, a master controller of a battery management system and several slave controllers of the battery management system, wherein the power supply source is connected to the current sensor, the current sensor is respectively connected to the electronic switch (K1) and the master controller of the battery management system, the electronic switch (K1) is respectively connected to the master controller of the battery management system and the slave controllers of the battery management system, the master controller of the battery management system is respectively in communicative connection with the several slave controllers of the battery management system , and each of the slave controllers of the battery management system is connected to a battery pack respectively. The isolated bidirectional constant-current maintenance system based on a power supply source of a shared device has the advantages of small volume, low costs, high power source conversion efficiency, bidirectional constant-current maintenance, low requirements for a power supply source, etc. The system can quickly improve the utilization rate of a battery, and effectively prolongs the service life of a battery pack.
