Question:
0 ~6 t1 r( [' G9 R% U2 L& hA lot of battery chargers control the charging process with help of electronic circuits. Also safety functions (limiting of current, timer, etc.) are controlled by electronic circuits. The cells of corresponding battery packs include a valve for opening if the pressure! t1 B* Y% y) u" T
inside the cellis too high. This pressure increases, for example, if the electronics of the charger does not work in correct wayresulting in overloading ofthe battery pack. Is it possible to consider this valve like a safety valve for protection against abnormal conditions if the safety valve function is tested separately?
