What are the maintenance methods of electric vehicle battery? What behaviors will cause the loss of electric vehicle battery
4hw.org: electric vehicles are the means of transportation for many people to travel at present. They are energy-saving and environmental friendly. However, many people find that the batteries will become more and more useless after the electric vehicles are used for a period of time. What's the matter? How to maintain the battery of electric vehicle? Let's have a look!
How to use and maintain electric vehicles
1. First, adjust the height of saddle and handlebar to make them in the safest and most comfortable position, especially the height of saddle. It is better to land both feet at the same time when you need to stop during riding.
2. Test whether the braking device is effective and reliable, and whether the power supply is cut off and whether the motor has stopped working after braking.
3. Check the electric quantity: when the power is turned on, it is particularly important to watch the electric quantity on the display, especially when it is used after long-term use. In addition, it is also necessary to check whether the relevant driving safety components such as electric horn and light are effective!
4. Check the rotating parts: whether the front and rear wheels, pedals, cranks, sprockets, chains and flywheels operate normally, and whether there is any foreign object collision.

5. Check whether the tire pressure is appropriate.
6. In riding, first of all, obey the road traffic rules. Do not cross the red light. Ride in the slow lane. Do not ride in the fast lane. When the traffic is crowded, turn off the switch and ride by hand. Slow down when turning, avoid sharp turning at a small angle when driving at high speed, resulting in a car accident caused by too much centrifugal force.
7. Never take people. Due to the small battery capacity and low power of the motor, the load capacity of the general electric bicycle is about 80kg (including the rider). If riding with people, it will increase the motor load and accelerate the battery consumption, thus reducing the service life of the battery motor, and it also violates the provisions of the traffic laws and regulations.
8. When riding uphill, on the bridge and against the strong wind, power and manpower should be used at the same time to reduce the load of battery and motor. Starting riding method: generally, electric bicycles have zero starting function, that is, turning on the switch when stationary, and turning the speed control knob can start the car. But at this time, the starting current is two to three times that of normal driving, which has a great impact on the motor and battery, especially the battery. Therefore, in order to extend the continuous mileage of one-time charging and the service life of battery, it is necessary to start by foot first, and then connect the circuit when there is a certain speed for three or four turns of foot, especially in busy traffic and lots of traffic lights. Frequent zero start-up will certainly shorten the service life of the battery.

The reasons for the premature aging of electric vehicle battery
Why does your electric vehicle battery produce premature aging and short life? The following is a compilation of several key points, which is willing to help you understand the causes of premature battery aging:
1. The owner has no awareness of battery maintenance, which causes serious battery vulcanization damage. You have to wait for the battery to run out before you come to repair it. At this time, it is more difficult to repair it. In fact, six months of maintenance, life naturally extended a lot, but the car owners do not have this awareness. Battery damage, mostly from the charger caused by excessive water loss start.
2. Charger is a killer. Divided into poor charger and aging charger, these battery killers usually play a killer role after 8 months of battery life. The reason is that the new battery meets the taste of these battery killers. With the aging of the battery, the battery can not meet the requirements of killers. By June of each year, the battery quickly loses water and becomes deformed.
3. The large starting current of luxury electric vehicle causes the battery to be vulcanized. If the owner starts the car and accelerates slowly, the battery life and driving mileage will naturally increase by 20%.
4. The motor controller is damaged, resulting in short battery life. The probability is not great, but there are many.
5. Riding without power loss has a long life. The new battery can be charged every time it uses electricity above the red light, but it can't run without power. Each time there is a loss of power, the service life will be less. The new battery with 10 times of power loss will be scrapped soon. It is necessary to charge in time to avoid power loss.
6. The most important thing is to charge properly: some people say that "the battery is not damaged but charged", which is true. The charging performance of battery plays an important role in the service life and performance of battery, so we must pay attention to the way of charging. According to the situation of the vast majority of users, the best choice is to charge the battery once when the discharge depth is 50% - 70%, so as to achieve the best effect of battery life. At the same time, the influence of temperature on the charging is also considerable. In high temperature season, the battery is overcharged. The temperature of the battery shall be reduced as far as possible to ensure good heat dissipation and prevent charging after exposure to the sun. Exposure to the sun will increase the temperature of the battery, increase the activity of various active substances of the battery and affect the service life of the battery. On the contrary, at low temperature, the battery has the problems of poor charging acceptance and insufficient charging. In this case, it is necessary to increase the charging voltage and extend the charging time, and take heat preservation and anti freezing measures, so as to ensure sufficient electricity and extend the service life of the battery.
