Dec 14, 2024 · The consistency of voltage in lithium batteries refers to the ability of individual cells within the same batch or system to maintain the same terminal voltage under identical conditions.
Do not let lithium batteries with different voltages in series. Due to the problem of consistency of lithium batteries, they are grouped in series under the same system (such as ternary or lithium iron), and they also need to be selected with the same voltage, internal resistance, and capacity.
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
Contributed Commentary by Anton Beck, Battery Product Manager, Epec When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
If different capacities or old and new lithium batteries are mixed together, there may be leakage, zero voltage and other phenomena. This is due to the difference in capacity during the charging process. Some batteries are overcharged when charging, and some batteries are not fully charged.
Do not let lithium batteries with different capacities in parallel. If different capacities or old and new lithium batteries are mixed together, there may be leakage, zero voltage and other phenomena.
In this paper, the single capacitor method is employed to achieve the energy balance between lithium-ion batteries. By controlling the on-off of the switch, the single battery with higher voltage in the battery pack is charged to the capacitor C, and then the capacitor C charges the battery with lower voltage.
