Electric vehicles are the second largest type of transportation in China, and many low- and middle-income families regard electric vehicles as their most important means of transportation. Electric vehicles are small and lightweight, and the driving speed is faster than bicycles, which provides a lot of convenience for everyone to travel. But electric cars also have a big flaw that upsets people – batteries aren't durable.
Many electric vehicles with a year or two after the endurance of the shrinkage of half, the night before just charged, the second day there is no electricity, especially in the winter, just charged not long after the battery jumped the green light, but when they ride, a twist to accelerate the handle power fell to 50%.
Some people feel that this is the quality of the electric vehicle itself, other people's electric vehicles have not appeared in two years, their own car riding a year on such a situation, it is definitely the battery quality is not good. However, the maintenance master said that this is not necessarily all caused by the quality of the battery, and sometimes the way the individual charges and the charging plug will also affect the life of the battery.
The first reason is that the charging current does not match
Different electric vehicle batteries have different battery capacities, and the current required for charging is also different. But some car owners have never paid attention to this problem, thinking that all electric vehicles can be charged with the same plug, and they don't care how much ampere the current of this plug is.
The smaller the current, the longer the charging time, if it is still calculated according to the original charging time, the battery is always in a state of dissatisfaction, it is easy to appear that it has been fully charged, but as soon as you ride out, the battery drops half of the electricity.
When charging, it is best to see how many amperes are used in the home socket, if it is smaller than the current required by the electric vehicle battery, extend the charging time, and do not unplug the plug in one to 6 hours.
The second reason is that the battery cable is loose
There are many cables in the battery pack, and abnormal connection lines will affect the efficiency of vehicle charging, sometimes it is not charged, and sometimes it is full as soon as it is charged. If you find that the electric vehicle is full of charging and dropping two electricity when you twist the handle, you can check whether the connection line in the battery pack is loose.
The third reason is that the battery has aged
The battery of an electric bicycle, like the battery of an electric vehicle, has a service life. After a long time of use, the battery will have problems such as crystallization and vulcanization. When the battery activity decreases, charging becomes difficult and the range is greatly reduced.
The battery of the current electric vehicle is basically composed of a battery pack, and the battery pack with a general capacity of 48V will have 4 small batteries. These 4 batteries will not age at the same time, you can go to the maintenance worker to test it, find out the battery in question, replace it, and save hundreds of dollars.
The fourth reason, the charger is faulty
Sometimes the battery is not charged enough to be faulty, but the charger is broken. Some electric bicycles match the original charger quality is not good, it can not be used a few times there will be a short circuit problem, and it will become a green light soon after the power is connected. The owner did not know this situation, and thought that it was fully charged and pulled the plug, only to find that it was not charged at all when using the car.
This problem is better solved, if it is a charger, the fault can directly buy a charger again. A battery charger is not expensive, and it can be solved by spending dozens of dollars.
