New Energy Sources WhatsApp$begingroup$ What would happen to the available current of the battery, if one of the cells was not at the same V level or charge capacity as the other 2 cells (e.g. 1 cell was 3.9V@75% charge & the other 2 cells were 4.2V@100%). The battery V would be less than 12.6V (as would be the case for 3 fully charged 4.2V cells), but how …
New Energy Sources WhatsAppThe battery configuration is S4 (four in series), and a fuse is connected to the positive side of the battery to shut it off when the current exceeds the limits. There is BMS Monitoring every cell voltage for balancing and fault detection. The current sensing unit will sense the charge and discharge its current to BMS.
New Energy Sources WhatsAppTo evaluate the strain and temperature from a 13.8 kWh battery pack, 96 FBGs are utilised spanning fourteen fibre optic sensor (FOS) strands. The FBG sensors were calibrated by putting the entire battery pack in a thermal chamber and subjecting it to temperature levels of 15 °C, 30 °C, and 45 °C.
