The battery pack monitoring scheme mainly includes four parts: communication management module, voltage monitoring module, current sensor, and battery temperature sensor.
Main functions
（1）Real time collection of voltage and surface temperature of each battery by each module;
（2）Equipped with automatic address allocation function, convenient on-site debugging and maintenance, and strong availability;
（3）Using intelligent analysis technology to provide forecasts for the backup time of battery packs during power outages in the city;
（5） The input port of the battery module is designed with anti reverse and recoverable fuse protection to prevent damage caused by improper construction, ensuring high system safety;
（6）Module structure design allows for flexible configuration of different numbers of battery packs, achievingLow cost solutionPlan;
（7） Provide RS485 communication interface to achieve remote monitoring function, which can be easily integrated into the application systems of third-party companies;
（8）The circuit port has EMC design and strong anti electromagnetic interference capability, especially for UPS battery packs with strong high-frequency interference, which can achieve high measurement accuracy;
