Lithium batteries are designed to operate efficiently over a wide temperature range (from −20 °C to 60 °C). Li-ion and lithium-polymer (Li-Po) batteries, which function at typical ambient temperatures, are particularly well-suited for EV batteries. Li-ion and Li-Po offer high specific energy and power but exhibit lower power density
Anode: Typically made of graphite, the anode is where lithium ions are stored when the battery is charged.; Cathode: Made of lithium metal oxides (such as lithium cobalt oxide, lithium iron phosphate, or lithium manganese oxide), the cathode is where lithium ions migrate during discharge.; Electrolyte: A lithium salt in an organic solvent, the electrolyte facilitates the

Taking the example of a reservoir to describe the battery may not be appropriate, but the principle is the same. We must ensure the voltage and capacity of each cell are at the same level, otherwise, the duration time and life of lithium battery will be discounted, the battery performance will also be declined.

The worst thing that can happen is thermal runaway. As we know lithium cells are very sensitive to overcharging and over discharging. In a pack of four cells if one cell is 3.5V while the other are 3.2V the charge will charging all the cells together since they are in series and it will charge the 3.5V cell to more than recommended voltage since the other batteries are still

Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing.
Simply put, balancing restores the original state aftereach full charge (see Figure 2). Depending on the configuration of the battery system and the type of cell, a amount of time certain must be allowed for balancing during each charging cycle. In conventional balancing, the affected charge is dissipated and lost.
