6 FAQs about [Solve the battery pack voltage difference by discharging]

What if there is a gap in a battery pack?

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.

How to increase the life of a battery pack?

One of the most significant factors is cell imbalance which varies each cell voltage in the battery pack overtime and hence decreases battery capacity rapidly. So as to increase the lifetime of the battery pack, the battery cells should be frequently equalized to keeps up the difference between the cells as small as possible.

How does voltage affect battery discharge performance?

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.

What is the voltage difference between cells of a battery pack?

Today 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.

How cell balancing is used in a battery pack?

There are different techniques of cell balancing have been presented for the battery pack. It is classified as passive and active cell balancing methods based on cell voltage and state of charge (SOC). The passive equivalent to the lowest level cell SOC. The active cell balancing transferring will be equal.

How to balance a battery pack correctly?

needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms.
