| description | The utility model discloses a digital communication interface suitable for being used between multiple serial-parallel battery packs. An universal asynchronous sequence transmission interface is used, an uplink and downlink circuit constructed by a voltage isolation module as well as a battery core low-voltage protection signal and an overvoltage protection signal in a digital interface which is directly connected to each battery pack in series, and a receiving and transmission signal transmitted by an universal asynchronous sequence and a compulsory wakeup signal used to awake a battery pack protection board microprocessor are matched at the same time. A constructed battery monitoring system allows battery packs with the same specification to directly serially connect digital signals needed by monitoring batteries, is convenient for the serial-parallel connection use of the multiple battery packs, can randomly replace necessary battery packs during the maintenance, and can greatly reduce the cost for electri |
