In the process of electric car battery, in addition to normal use and abnormal power consumption, there is a way of discharge, this way is very small, so often ignored by the people, but, after a long time the dangers of also is very big. And this way is to discharge. Actually, not to say there are a lot of users have feeling, sometimes, it is full of electricity, but place a week later, was full of electricity grid has turned out to be less than hundred, thought it was the battery, actually otherwise. This is all electric vehicle battery to discharge some normal phenomenon, as is often the case, the battery will automatically every day one percent to two percent of the battery discharge, after a long time will put off all electricity, therefore, place a month battery power only half would happen.
And the reason why the electric car battery discharge phenomenon, mainly due to the following reasons: first, the storage time is too long this is a normal consumption, so there is no need to worry about the place. After the battery is placed in a long term, it will be discharged because of the change of the density. Two, impure electrolyte containing electrolyte impurities in battery electric vehicle regular manufacturers are very pure, without impurities, so the discharge is very slow, in the normal range. And some electric car battery discharge speed is very fast, the main reason is that the electrolyte is not pure, containing impurities, so the formation of a certain amount of potential difference, resulting in battery short circuit, power consumption. Three, there is a short circuit or battery external bypass according to professionals, when the battery is extracted and the external wire body formed when the bypass, or battery wire, wrench and easy to form positive and negative when connectivity, there will be severe discharge phenomenon.In addition, when the battery shell or the top cover locations of the leakage of the electrolyte, it will lead to discharge. So, how to prevent the electric car battery self discharge it? There are also three methods: first, to strengthen the maintenance, timely charging and charged all of the goods, electric vehicle batteries also need maintenance, maintenance is not only in order to prolong the service life, but also to allow the battery to serve us better. In the maintenance process, should pay attention to the cleanliness of the battery, often check whether there is damage. In addition, the use of the battery, if found for fifty percent, it should be timely charging, do not wait until no electricity to think up to charge. Second, take care of the electrolyte battery is very important, so it must be handled with care in the process of moving, to avoid collision damage cause electrolyte leakage of the shell.
