48V iron-lithium battery pack intelligent balance module
Design principle:
* The BM3000 system is different from the traditional passive design scheme, mainly adopting different active balancing strategies for different working modes of charging and discharging:
* When charging, the overall high-current main charge is used. When the voltage of any single battery in the system reaches the upper limit of the charging protection, the main charge is cut off, and the high-efficiency built-in DCDC module is used to charge each single cell individually. The traditional The battery BMS just cuts off the main charge and it stops. In this way, the energy of the battery pack can be quickly supplemented, and each battery cell can be fully and independently balanced.
* The strategy of “robbing the rich and helping the poor” is adopted when discharging, and a small part of the energy is extracted from the entire battery pack, and injected into the lower-capacity single cell through the high-efficiency DCDC module, which can be understood as making the larger-capacity battery output relatively large , The output of a battery with a small capacity is relatively small, and the maximum discharge potential of the entire group of batteries is realized, which can extend the discharge time without over-discharging any cell.
