Electric vehicle battery charging and charging owe what harm

Electric vehicle battery charging and owe what harm of charging the electric vehicle battery charging current is greater than the current for the battery, the part is more charge, charging mainly produce electrolytic water side effects, because the battery positive electrode produce oxygen transfer to the cathode oxygen compound reaction, heat will happen, so charging amount actually converted into heat make a battery temperature, if not controlled, can cause a lot of water loss, serious cause collapse 'thermal runaway' capacity, and even fault deformation, etc. Owe charging popular speak is not often in charge are in the under charge, under the condition of extreme will gradually form a bulky solid lead sulfate, it almost insoluble, which produce the so-called 'irreversible sulfate, use common method can't charge it into electricity, so the capacity will again fast attenuation.
