There are many kinds of signals in the battery system for 14.8V Lithium Battery Rechargeable, and the battery management system is generally distributed. In the process of signal acquisition, different control sub-board signals will have synchronization problems, which will affect the real-time monitoring algorithm. When designing BMS, it is necessary to put forward corresponding requirements for sampling frequency and synchronization precision of signals.
New 14.8V lithium battery rechargeable cell using military-grade smart IC chip, with overcurrent, overpressure, overcharge, overcharge, undervoltage, short circuit, reverse connection, equilibrium voltage and equilibrium charging and other multiple protection functions) to ensure the safety and reliability of the battery pack
