Every winter, the three-wheeled electric vehicle obviously does not run far, but the test results show that everything is normal for the three-wheeled electric vehicle without any problems. Why is this? Does the three-wheeled electric car not run far have anything to do with the cold weather? When the temperature is around 25℃, the lead-acid battery can store electricity normally and can discharge to the maximum; when the temperature drops below 10℃, the power stored by the lead-acid battery will be reduced by 20%. When the temperature is below 0℃, the stored electricity will be reduced by 30% or more. Therefore, even the newly purchased three-wheeled electric vehicles may suffer from poor endurance in winter. In addition, it is caused by poor charging habits of consumers. Here are four secrets of battery charging in winter for everyone, listen and remember!
01 Can't wait for the battery to run out before charging
Lead-acid batteries are different from other batteries in that they have no memory effect, so no matter what state of charge the battery is in, it can be charged directly without discharging. Some early users of three-wheeled electric vehicles thought that it is best to recharge the batteries after they are basically used up. This view is incorrect. Frequent discharge of electricity has a greater impact on the life of the battery. If it is not used in winter, it is best to charge the battery twice a month to ensure the storage capacity of the lead-acid battery.
02 The charging environment should not be too cold or too hot
The best ambient temperature for charging is 25°C. Now most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better. When charging, it is best to arrange the battery and charger in a ventilated and temperature-regulated environment.
It is specially reminded that when the battery is in the northern winter and enters a warm indoor at a low outdoor temperature, frost and condensation will appear on the surface of the battery. In order to avoid battery leakage caused by frost and condensation, you should charge the battery after the battery temperature rises to close to the indoor temperature and is dry. It is recommended to charge the battery 30 minutes after entering the room.
03 Develop some good habits to save electricity
Under the premise of ensuring safety, braking and starting should be minimized during driving to save electric energy. When going downhill, take advantage of the advance power reduction and coasting to decelerate as much as possible. When going uphill, especially when climbing at a low speed, the current should not be too high. Before going out, check whether all the accessories are in good condition. In case of rain and snow, do not let the water flood the motor, so as to extend the life of the battery and motor.
04 Maintain the battery well and don’t use the charger indiscriminately
Misuse of different types of chargers may cause the battery to leak, generate heat, smoke, fire or explode. When the battery is deformed or swollen, the battery charging should be stopped immediately.
Nowadays, most of the three-wheel electric vehicle batteries use lead-acid batteries. The cruising range has a lot to do with the outdoor temperature. It is normal for the battery power to decrease in winter. But if you master the above charging tips, you can reduce the cruising range of your three-wheel electric vehicle at least!
