Checking and checking again

Any system can have a failure or an irregular operation. That is why it is important to perform multiple tests and verifications of each installation.

With battery systems the possibility of a failure or malfunction is multiplied by the number of the cells or the complexity of the installation. For a system with 2 cells, with 20 cells and with 200 cells the possibility of “problem” will be multiplied 2 times, 10 times and even 100 times.

The photo shows an example of a failure of the BMS system in a 4 cell installation. The BMS module reports a voltage and temperature that is not correct. Making a measurement of the cell proves the failure condition of the setup. In this case, caused by a defective BMS module that needs a replacement.

Our recommendation: the battery pack should have regular inspections and verifications performed.
