　　Balancing principle of series UPS power battery pack

　　1. The series UPS power supply battery pack is a high-power battery pack that supplies power to the car in an electric vehicle. In order to ensure the capacity of the entire battery pack, it is necessary to perform balanced management of the battery.

　　2. Various battery management ICs on the market for series UPS power supply battery packs provide voltage equalization management functions, and users only need to connect some external components to realize it. Unfortunately, most battery management ICs use The balance between each battery is achieved by means of resistor shunting/power consumption.

　　3. Series UPS power supply battery pack In the era of lead-acid batteries, there have been various ways to balance the battery pack.

　　4. Resistive shunting and energy consumption of lithium-ion batteries connected in series. This method is the most common and easiest method on the market. The protection boards for battery packs exhibited at the 2009 Electric Bicycle Exhibition also include protection boards for electric vehicles, and their equalization methods are realized by resistors. The reason is also very simple: easy to implement, there is no better way. It is actually the cheapest way.
