The worst thing that can happen is thermal runaway. As we know lithium cells are very sensitive to overcharging and over discharging. In a pack of four cells if one cell is 3.5V while the other are 3.2V the charge will charging all the cells together since they are in series and it will charge the 3.5V cell to more than recommended voltage since the other batteries are still …
To efficiently evacuate gases generated during TR, degassing valves are installed in the battery pack housing. The type and number of valves are designed based on the cell''s gas mass flow. To prevent ignition of the gas/air mixture outside the battery pack, large smoldering particles must be kept inside, for example, by using filters.
