The 16-20S universal intelligent BMS protection board is designed specifically for 60-72V lithium batteries and is suitable for ternary lithium, lithium manganese oxide, lithium iron phosphate, and lithium titanate battery cells. Adopting a universal low edge (negative control) driving scheme, drawing inspiration from the automotive BMS architecture, providing multiple safety protections, effectively enhancing the safety of lithium battery products. Supports RS485 and CAN communication to meet various communication application needs of users. In addition to the conventional communication handshake mechanism, BMS and charger can also use patented technology of "single wire self-locking wire and identification control technology" for communication handshake, reducing costs while ensuring the safety and reliability of the charging process. Optional Bluetooth module, allowing users to view and set various battery information and parameters through a mobile mini program. In addition, by selecting GPS modules, multiple precise positioning based on LBS base stations, Beidou, GPS, etc. can be achieved, supporting remote power outages and real-time monitoring of voltage, charging and discharging current, battery cells, and other data.
