7 tips for identifying electric cars new battery cycle life

It is the new battery of electric cars battery, but use after a period of time, battery is becoming worse and worse to use. It does not run for a long time before the power goes out, what is going on?

Electric cars to replace new batteries far range after cause analysis:

1, motor.This will be the first thought.Power consumption current is big, such as motor demagnetization.

2, the controller.With drift after a period of time parameters, for instance by high voltage.

3, mechanical resistance problem.Such as insufficient TaiQi, bearing, brake, etc.

4, the influence of the low voltage charger to the battery.48 V electric vehicle batteries, for example, to reach full time at 58.8 + / - 0.2 V voltage.If the charger highest load voltage is lower than this value, which can determine the charger could not make electric vehicle batteries fully charged.Battery, will naturally affect the range of electric vehicles.

5, line.There is nothing wrong with the parts problems belong to the soft fault, circuit, just on the connection of resistance, the resistance is the partial pressure, and the bigger current partial pressure.New battery twist to turn off the lamp.This problem is very common, run not far from the nine times out of ten is it.

6. In the process of electric vehicle battery and charging and discharging, there will be a "cure" phenomenon influence the battery capacity.Sulfide is refers to the battery in use process due to the electrochemical reaction, the plate will gradually covered by hard lead sulfate crystallization, results in the decrease of active plate area is reduced gradually and acid concentration and battery capacity decline.

7. Electric vehicle battery voltage during summer and winter seasons, such as the environment variable pressure without the right to adjust the charger, battery overcharge will make the summer causes deformation, battery fluid loss eventually lead to beat, a drop in mileage.

Electric vehicle battery life depends mainly on the above aspects.Battery is good or bad will directly affect the service life and range.So usually need to pay special attention to the maintenance of the battery.

Can be said to be the life of the electric vehicle batteries, if some is not very good quality battery gears will be replaced the cost will not buy a relatively safe, good quality battery to safety, so in choosing a battery try to choose high quality, strong stability of high-end battery.
