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.
All parties must account for the added cost and time resulting from testing the printed circuit board assembly before assembling the battery pack. However, it pays dividends when the long term cost savings, thorough testing, troubleshooting, and ease of repair result in a high quality end product with a lower instance of failure in the field.
Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
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.
Hardware-type protection board: 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.
Testing the BMS software and hardware is typically done at the pack level to ensure that all parts of the battery work together and that the BMS performs safely and accurately. Engineers need to test the BMS to meet industry standards such as ISO 26262 and IEC 62304. Temp. Sensors BMS interfaces include pack inputs and outputs.

How to safely test a lithium battery management system board
I was thinking of buying for the first tests a 2s or 3s commercial lithium battery pack with protection (short circuit, overvoltage, undervoltage per cell,…) already integrated (unspecified IC). I am unsure whether that protection circuit might interfere with the normal operation (measurement accuracy,…) of the bq40z50, invalidating the test.
