Why are electric vehicle battery charging fever? Electric car battery heating

According to electric car owners reflect in electric vehicle battery charging fever phenomenon, now is the season of temperature rise, the electric car battery charging in the incidence of fever will gradually increase, it will become the electric car owners worry of! Therefore, I am here for the simple analysis of the cause of the battery heating electric car owners, thought that battery heating users don't know reason, hope can help to you! Electric vehicle battery fever has two cases, one kind is discharge fever, the other is a charging fever. 5 c. 1) When the motor rated voltage value, low battery capacity is small, working current is larger, the voltage will be drastically reduced, also quickly consumption capacity, most unfavorable for the battery. 2) Battery of the electrochemical reaction rate can only keep driving, often do the whole circulation charge and discharge, a bit not note will consume. Meet the wind uphill, great power consumption, rapid reaction force battery plate, the heat of the battery case is higher, can make the battery damage, shorten life. 3) Ideal is the battery of the electrochemical reaction rate fully supply enough electricity. Battery shell heat without exception, the battery capacity is enough. 2, charging in the process of hot charging fever, likely the cause of the problem are as follows: 1) Its problems, battery aging, internal resistance, electrolyte dried up, internal short circuit and cause fever. Battery with the increase of using the number of times, this includes discharge and recharge, progressive loss of water molecules in the battery, this is our battery analysis of gas and water loss, which leads to batteries in the electrochemical reaction heat; Other sulfuric acid is formed in the process of charging and discharging the battery solution crystallization and precipitation glue paste on the lead plate, which resulted in increased cell resistance and heat; These two types of problems can be through technical means, such as water, sulfur extremely. If the battery is for sprint away, fever caused by battery, the best replace new battery. 2) Charger, charger is not general pulse function, more no negative pulse elimination polarization functions, this kind of charger is not usually in the late charge constant pressure, and battery voltage exceeds allowable values, which leads to batteries a lot of gas, water and heat. Ordinary charger in the market now, just a hide of constant power charge, or the battery internal resistance, and so on and so forth can't timely detection, detected also cannot make and charging into the adjustment or can't give the best charging schemes, these are the cause of battery heating charging process. To fundamentally solve the battery heating caused by the charger problem, it must be correctly choose electric car chargers, battery charging process is an electrochemical reaction process, in this process, if appear trace heating is belong to normal batteries, if the fever is unusual, in the case of battery performance is good, belong to the charger.
