(1) Advanced internal resistance detection technology - small signal pulse AC method, real-time online monitoring and analysis of the trend of internal resistance changes in batteries, predicting outdated batteries in battery packs;
(2)High security. Equipped with multiple protections such as power isolation, optocoupler isolation, and fuse protection, it does not affect the operation of the battery pack;
(3)Real time collection of voltage, internal resistance, temperature, and total current of each battery cell;
(4)The battery monitoring module address has an automatic allocation function, making debugging "foolproof" and simple and practical;
(5)Reserve one analog acquisition channel, connected to 4-20mA sensor signals, for detecting environmental temperature, mains voltage and other parameters;
(6)Dual watchdog design with self recovery function and strong stability;
(7)Provide early prediction of the operating status of the battery pack, and provide reliable basis for battery maintenance or replacement;
(8)The circuit port has EMC design and strong anti electromagnetic interference capability, especially for high-frequency UPS battery packs, which can achieve high measurement accuracy;
(9)Provide RS485 communication port to achieve remote monitoring function and facilitate access to third-party company application systems.
