Customer ServiceToday we will share with you the voltage difference between the cells of a battery pack. Actually, the difference within a certain range is acceptable, usually within 0.05V for static voltage and within 0.1V for dynamic voltage. Static voltage is when a battery is resting, and dynamic is when a battery is in use.
Conversely, the larger the voltage difference, the less consistent the battery pack--and as a result, the discharge performance will be adversely affected. The discharge energy of the battery pack becomes insufficient, and it gradually deteriorates as the number of cycles increases.
In addition, the battery pack is affected by factors such as charging conditions and temperatures, which can cause voltage differences to appear and gradually increase. If we compare a battery pack to a reservoir made up of individual tanks connected together with the water pressure in each tank being the same, their output will also be the same.
If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference. This is all that we’re covering today.
The best method in preventing cell voltage difference is to match the cells before the battery pack is assembled and to select the cells with the closest consistency for assembly. To put it simply, you match the batteries with the most similar specifications according to the configuration of the battery pack.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
