▎ 摘　　要

NOVELTY - The system has a battery information collecting unit (10) connected with a control unit (16)for collecting battery parameter information. A temperature sensor (12) is connected with the control unit to collect battery temperature information. The control unit is connected to the battery information collection unit, the temperature sensor and an execution unit (14). The battery information acquisition unit receives the battery parameters information sent by the battery collection unit for receiving the temperature information of the battery sent by a temperature sensor. The execution unit generates an operation instruction according to the voltage information and the battery voltage information, and sends the operation instruction to the execution unit. USE - lithium titanate graphene conductive medium power supply system charging and discharging protection system. ADVANTAGE - The system monitors the battery parameter information and battery temperature information in real time through the control unit, and the fuse operation is performed by three-end fuse fuse, so as to provide protection to the power supply system. The battery information collecting unit collects battery capacity, charging voltage, discharging voltage, charging current and discharging current, and obtains the battery temperature through the temperature sensor. The system timely executes the three- end fuse fuse fuse instruction through the executing unit, so that the battery of the system, power supply and external load can be protected, thus improving the safety of the battery and the system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium titanate graphene conductive medium power supply system charging and discharging protection method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a lithium titanate graphene conductive medium power supply system charging and discharging protection system.
