In the battery system, battery inconsistency is the root cause of many problems in the current energy storage system, and the main factor affecting battery inconsistency is not only the battery itself, but also the more critical equalization capability of the BMS. Compared to passive equalization, active equalization compensates for the differences in battery packs in a fast and effective way with energy transfer, ensures battery consistency, extends the service life of the battery packs and the average time without failure, and effectively improves the economic benefits of the whole life cycle of the product.

Active equalization will be higher than passive equalization in the initial investment, so how to not increase the initial investment costs, but also when necessary to increase the active equalization on demand has become an urgent problem, XNeTech has developed a plug-in removable active equalization BMS for this demand, and according to the battery situation directional installation can significantly reduce the cost of active equalization. HipNeng Technology proposes: external split-targeted active equalization BMS solution - realizing on-demand equalization through the combination of hardware and software.

（external split-target active equalization BMS)

• External mounting, eliminating the need for wiring harness adapters, facilitates installation and maintenance.

• Split usage makes it possible to add active equalization on demand.

• Flexible increase or decrease of active equalization module, and according to the hardware selection target implementation of active and passive equalization strategy.

• Hardware circuitry does not borrow external power supply, truly plug and play.

• The software accurately determines the packs that need to be equipped with active equalization and makes prompts.

• Implement active equalization strategy for packs with active equalization through settings.
