Production fault - reversed polarity

Blog EVPower

Sometimes a mistake may happen…. This photo shows athat has areversed polarity marking. The problem was cased during the final part of the production, as the outer sleeve with the polarity symbols (plus/minus signs) was put in opposite direction. The cell is completely OK, only the marking is reversed.

This real situation shows that even, a faulty product may slip out. This case also shows the need for the final responsibility of checking during the installation of the cells. There is always need to check everything to the very last detail and not relying just on signs and marking.

Checking and checking again

Blog EVPower

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 systemsthe possibility of a failure or malfunction is multiplied by the number of the cellsor 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.
