1 Sorting: Batteries of different batches should not be used together in theory. Even cells of the same batch need to be screened, and cells with relatively concentrated parameters are placed in the same lithium battery pack and in the same battery pack.

2 Thermal management: For cells with inconsistent internal resistance, the heat generated is different. Adding a thermal management system can adjust the temperature difference of the entire lithium battery pack to keep it within a small range.

The cells that generate more heat still have a high temperature rise, but they will not open the gap with other cells, and there will be no obvious gap in the deterioration level.

3.Battery balance management: To solve this problem, the battery management system BMS has designed a balance function.

To ensure a good use environment for the lithium battery pack, try to ensure a constant temperature, reduce vibration, and ensure that water, dust, etc. contaminate the battery pole.

Master the development law of the inconsistency of single cells in the lithium battery pack, and adjust or replace the batteries with extreme parameters in time to ensure that the inconsistency of battery pack parameters does not increase with use time.

4.  Energy management strategy: In terms of energy management, when the output power allows, try to reduce the depth of battery discharge.

Introduce a practical battery pack energy management and balance system, formulate a reasonable battery balance strategy, actively intervene and reduce battery inconsistency.

Try to prevent the battery from being deeply discharged while avoiding overcharging of the battery.

    How to judge the consistency of the lithium battery pack?

The consistency of the lithium battery pack needs to be judged by using special tools to measure the capacity, internal resistance, and charge-discharge curve. Professional instruments and equipment are used here: lithium battery sorting machine,  sub-capacity cabinet,internal resistance tester, etc.
