Electric vehicles can be regarded as the most cost-effective means of transportation in life. It is really convenient to use, but sometimes it does make owners very “upset”. In particular, the endurance of electric vehicles is generally not far. Although there are a few models that can reach one hundred or even two hundred kilometers, most people use electric vehicles that have a endurance of about 50 to 70 kilometers. If you encounter the endurance decline, it will seriously affect the practicality of the vehicle.
If an electric car is several years old, it is understandable that the battery life is not good. But if the battery life of the electric car is reduced after only one year of riding, how to deal with this situation? What are the solutions? Xiaobian today to give you a few moves, hope to help these distressed owners.
Case one: Voltage difference between batteries
Inside each group of electric vehicle batteries are composed of multiple 12V group batteries. Once there is an obvious pressure difference between the group batteries, it will lead to a decline in the endurance of electric vehicles.
The appearance of pressure difference is mainly due to a group of batteries in multiple charging and discharging when the battery positive or negative electrode first discharge, first charge. This causes the voltage and current to be lower or higher than that of other batteries, resulting in voltage instability that affects battery life.
Solution: For this situation, we can install a battery equalizer for the electric vehicle, which can prevent the voltage imbalance between the battery cells inside the battery resulting in reduced service life. When the voltage imbalance between battery cells, different cell charging and discharging speed is different. When a cell is charged, other cells are in the state of overcharge or undercharge, and overcharge or undercharge will damage the battery, resulting in reduced battery capacity and shortened battery life. The battery equalizer ensures the power balance among battery cells in real time, extending the battery service life by 5-30%.
A battery equipped with an equalizer transfers the power from a battery with a high voltage to a battery with a low voltage to compensate through active equalization to achieve charge balance so that each battery is fully charged, and finally realizes energy transfer to extend the battery mileage and the service life of the battery pack.
Case two: The battery electrolyte is insufficient
Although most of the electric vehicle batteries now, the electrolyte can theoretically be used for 2 to 3 years, but some owners of the bad charging habits will lead to accelerated electrolyte consumption, when the electrolyte is insufficient, the activity of the active substance responsible for the conversion of electric energy decreases, charging and discharging efficiency will be reduced, battery storage will be reduced, affecting the battery life.
Solution: In this case, we can solve the problem by adding liquid on our own.
Case three: The brake does not return
Sometimes it is not necessarily a problem with the battery. After all, the battery of the electric vehicle that has only been used for one year is relatively new and the aging degree is not high. There is also a common situation that leads to the decline of electric vehicle endurance, that is, the brake does not return, resulting in greater resistance to vehicle driving and increased power consumption.
Solution: In this case, the solution is simple. We only need to find the brake pump assembly, the brake does not return is generally the screw loose here, we only need to take a wrench to screw the screw inside a circle, will find that the wheel rotation is easier, solve the problem of increased power consumption, can restore the endurance of the vehicle.
Summary: Electric vehicles have only been used for 1 year, even if there is a problem with the battery, it is far from the point of need to replace the battery, so in this case, Xiaobian is very disagree with some businesses directly require owners to change the battery proposal. Generally use 1 year electric vehicle endurance decline and “voltage difference, electrolyte shortage, brake not return” these factors are related, owners may wish to use small series for everyone to share the tips to try to repair. If you are not sure, you can also find business assistance, do not directly change the battery, can save you a lot of costs.
Finally, Xiaobian also needs to remind you that, in addition to the problems of electric vehicle endurance to be solved in time, if you can maintain good cycling habits and charging habits in the daily process of using the car, and with the help of scientific and technological means to maintain the electric vehicle battery, it can also make the battery life of electric vehicle better and longer.
