Tips for protecting batteries and chargers of electric vehicles at high temperatures
1. No inferior charger. Poor charger voltage and current instability, poor heat dissipation, often used not only to cause harm to the battery, but also may cause fire.
2, do not change the charger at will. The charger parameters of different electric cars are basically different. Don't change chargers or other chargers when you don't know the charger.
3. The charger is not allowed to be jolted for a long time. Generally, the charger is rarely used, most of which are bumpy in the course of riding, so the charger is not resistant to strong vibration, so the charger is generally not placed in the trunk of the electric bicycle and in the basket. The charger can be packed with foam plastics to prevent vibration and jolt.
4, develop the habit of charging every day. It is recommended that you charge every day, and the battery life will be extended. If it is not used frequently, the battery will produce a kind of "memory", which will affect its mileage and also lose its battery mission.
5, there should be plenty of electricity every day. When the charger is in the color of the indicator edge, it looks as if it is full of electricity. Actually, the battery is not full. In the long run, there will be a lack of charge accumulation. Therefore, the battery will continue to charge for a while after it becomes full of electricity, so that it can prevent the battery from being vulcanized.
6. Complete discharge on a regular basis. Under the normal load of flat pavement, ride to the first undervoltage protection, and complete the battery after complete discharge. A full discharge of the battery on a regular basis is also beneficial to the activation of the battery, which can slightly increase the capacity of the battery.
7, pay attention to the environment of charging. The best environmental temperature is 25 C, in winter or in summer, there will be overcharge or under charge, so batteries and chargers are generally arranged in a ventilated and room temperature environment of about 25 degrees C.
8, do not allow the battery to be insolate at high temperature. Don't put an electric car in the sun. The high temperature environment will increase the internal pressure of the battery and make the battery pressure limiting valve automatically open. The direct result is to increase the water loss of the battery. The excessive loss of water in the battery will inevitably lead to a decrease in the activity of the battery, the softening of the accelerating plate, the heating of the shell when charging, and the fatal damage of the shell such as drum and deformation.
9, develop a good habit of saving electricity. When a red light or downhill is about to happen, try to reduce the brakes as much as possible by using the early power cut and gliding deceleration. When starting, slowly turn the handle to avoid the impact of high current on the battery, and reduce the battery's power loss and life damage.
10, when charging, plug the battery box plug and plug in the power supply.
