电动车电池坏损成因、修复和保养方法（Causes, repair and maintenance of battery damage in electric vehicle） Causes, repair and maintenance of battery damage in electric vehicle The battery as convenient power has been widely used by people, is also rare in 2003 before the ordinary people used directly with the electric car in Chinas popularization of battery continues to improve, more and more people living close to people, but also on the battery solution: whether the little knowledge of how bad loss too fast, battery capacity the battery can reduce the repair, how to maintain the battery question and so on, here we only on the electric vehicle battery damage, repair and maintenance of the causes are as follows, for reference. Causes of battery damage Electric vehicles generally use maintenance free lead-acid batteries, the electrolyte is colloidal, divided into 24V, 36V, 48V and 60V. On the market, 36V and 48V are many, 24V and 60V are few. 24V is two, the 36V is three, the 48V is four, and the 60V is five 12V. The single cell battery is connected in series. Each cell is 12V, and consists of 6 separated series. Every 2V, there are positive and negative plates and colloid electrolyte every day. Battery damage reason is very complex, roughly divided into the following 6 kinds: 1, overcharge lead to battery damage. Overcharge is a phenomenon that destroys the chemical and physical properties of a battery when it is charged too much to the battery. Overcharge is the first cause of the charger. The current electric car charger has a safe charging voltage settings, charging voltage is generally set in the battery standard voltage of less than 1.2 times, such as 48V batteries, charging voltage is set within 57.2V. The battery in the discharge process, the voltage will gradually decline, when once again to the battery charging, the charger will be bright red, said charging, when the battery power input voltage constant, will continue to rise, to close or equal to the charging voltage of the
