Do not know if there is no such user, as soon as possible in order to full power, or when charging, the urgent need for the use, by increasing the current to the battery. This will not only reduce the charging time, while also ensuring full power, not less. Well, do you do that?
Not good! And is very bad. Why? Originally, every electric vehicle batteries in the production process are certain specifications, manufacturers in accordance with the specifications for production, all data have been fixed. And because the charging current is relatively small, battery charging time is relatively long, probably in about eight hours, so go home at night one night charge. The next day use just in time. However, some people often forget to charge in the evening, when the day to use electricity is not enough.
Therefore, want to overcome this problem by a large current. But it backfired, after the current increases, not only can not make electric vehicle batteries to charge capacity, but will cause the battery to heat up very fast, produce a lot of heat and gas, leading to internal battery active material shedding, thereby affecting the service life of the battery electric vehicle.
Not only that, professionals also pointed out that when the charging current, will lead to polarization phenomenon. So, what is the polarization phenomenon? Polarization phenomenon is a kind of phenomenon that the secondary charging, mainly electric vehicle battery charge and discharge, positive and negative polar reaction polarization, both potential move, which damage to the battery very large. After again and in the electric vehicle battery charging process, the concentration polarization will be more obvious, stop charging, diffusion will aggravate the disappearance, also is to say, although it is full of power, but he does not like the slow charging that use time long.
