BMS stands for Battery Management System. It protects the battery from over-voltage, under-voltage, over-current, high temperature, or short circuits. Additionally, the BMS will shut off the battery to protect it from unsafe operating conditions. All Polinovel batteries have a built-in BMS. 


The reason may be related to the the conformity of the battery. In this connection, it is more difficult to make good conformity on different batteries, or the cells in different batteries. The voltage difference between the batteries will get large too, which in turn may lead to high impact current inside the batteries, and damage the BMS.

Active balancing is realized in the form of power transfer, which relies on expensive chips and transformers, and also requires peripheral components that are larger and more costly. It is mainly used in electric vehicle applications. Balancing plays an auxiliary, not a deciding role. The core is to guarantee the battery’s conformity.
