It's not charging right
< br >
Whether you are still using a mismatched charger to charge your small donkey, although this saves time and money, but do so for a long time, will lead to the battery charging when the power supply heat, excessive heat, shorten the battery life.
< br >
Correct approach: It is recommended not to easily use other brands of chargers, so that special cars are dedicated.
< br >
Fever caused by a problem with the charger
< br >
The general charger has no pulse function, but also no negative pulse to eliminate polarization function, such chargers usually can not be constant voltage in the late charging period, so that the battery voltage exceeds the allowable value, resulting in a large number of battery gas out, water loss, heat.
< br >
What to do: It is necessary to buy a better quality charger.
< br >
The battery itself
< br >
Continuous high temperature, electric vehicle battery is affected by the ambient temperature is easy to lose water, if the loss of too much water battery is not timely replenishment, then, when charging the charger will increase the current to charge the battery, making the battery more and more hot when charging, ultimately, resulting in the battery temperature exceeds the battery plastic shell can withstand the temperature, resulting in battery bulge deformation, accelerating the aging of the battery.
< br >
Correct approach: It is necessary to go to professional maintenance stores in time to replenish the battery, and at the same time, try to choose high quality and good reputation brand batteries when choosing batteries.

I hope that after understanding these reasons, you will pay more attention to strengthening the maintenance of electric vehicles and help your car to \"cool down a summer\".
Possible reasons are as follows:
● Discharge too fast, it may be that the lithium battery capacity is small, and the discharge current exceeds 0.5C for a long time
● When the rated voltage of the motor is low, the battery capacity is small, the working current is large, the voltage will be sharply reduced, and the capacity will soon be consumed, which is the most unfavorable to the battery.
Normal phenomenon, lithium battery heating phenomenon is a common phenomenon in life, often appear in the use of lithium battery as a power supply of mobile phones, laptops and other wireless household appliances, due to the lithium battery in the discharge of the battery inside the chemical reaction, produce a lot of heat energy, resulting in a rise in battery temperature, so that we touch the hand will feel the temperature, This is a common phenomenon in most lithium batteries.
