Cell Balancing for Maximum Battery Pack - ION Energy
Sep 02, 2019· Due to this, the capacity of the battery pack is limited by the imbalance in the cells of the pack. This reduces the energy usage efficiencies and shortens the lifetime of the battery pack. Therefore, battery cell balancing is a basic, but essential function of a Battery Management System (BMS) and is necessary for battery packs. The following

Lithium-ion battery - Wikipedia
A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging. Li-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode.
