What happens if a lithium battery is used in pack?

When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.

How to protect a lithium battery?

Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.

Can a lithium battery be overcharged?

Because of the material characteristics of the lithium battery itself, it can not be over-charge, over-discharge, over-current, short-circuit and ultra high or low temperature charge and discharge, so the application of lithium battery always needs a protection circuit.

Can a charge port and discharge port be separated?

But some customers’ charge port and discharge port share a common port, some customers require the charging port and discharge port can be separated wiring. The over-current capacity of the protective board is determined by the over-current capacity and quantity of the MOS tube.

What is a common port battery management system (BMS)?

One of the key benefits of a common port battery management system (BMS) is its simplicity. When building a battery pack with a common port BMS, you only need to wire a single set of cables to the battery. In contrast, separate port BMSs require running separate charge and discharge lines, adding complexity to the wiring.

What is the difference between charging and discharging circuit?

Charging and discharging circuit is different, i.e., charging and discharging port are separated. Charging and discharging circuit is the same circuit, i.e., charging and discharging share a same port. Why do we need to distinguish between common and separate port? For customers, generally do not care about the separate port or common port.
