Users who use electric vehicles on a daily basis must have experienced this experience: the electric vehicles are also fully charged. They can run for about a week in summer, but they may run out of electricity in two or three days in winter. Curious car owners may ask, "is the range of electric vehicles related to the temperature?" "Is it true that the higher the temperature, the longer the range of electric vehicles?" Now Xiaoxin will answer your questions on the above questions. As we all know, the higher the charge and discharge rate of electric vehicle battery, the longer the endurance mileage of electric vehicle. Theoretically, the charge and discharge rate of electric vehicle batteries can be as high as 105% in summer, 100% in spring and autumn when the temperature is about 20 degrees, and less than 80% in winter. It can be seen that within a certain range, the temperature is directly proportional to the range of electric vehicles (the higher the temperature, the longer the range of electric vehicles). In addition to the temperature, there are many other factors that affect the range of electric vehicles:

1、 Charging mode
Many electric vehicle users charge all night for more than ten hours, which is easy to cause overcharge damage of the battery and shorten the mileage.
The correct charging method is to select the charger matching the battery and charge it for 6-8 hours after 60% - 70% discharge. If the electric vehicle is not used for a long time, remember to charge it every two months. Otherwise, the long-term power loss of the battery will cause irreversible sulfation and accelerate the "decline" of the battery. The correct charging method can not only protect the battery, but also prolong the service life of the battery.

2、 Service life of complete vehicle
The service life of electric vehicles is generally 3-5 years. With the increase of service life, the performance of electric vehicles will naturally decline, and the endurance capacity is no exception. In addition to affecting the mileage, the lines of electric vehicles will also age, and there is a certain risk of spontaneous combustion. Xiaoxin reminds all car owners that in case of line aging, they must be replaced in time and safety first.

3、 Braking mode
Frequent emergency stop and brake will damage the battery due to high current discharge, thus affecting the mileage. When accelerating, especially when the electric vehicle starts, turn the handle as slowly as possible and continue to accelerate when the speed comes up. If you need to brake, you can release the handle in advance and try to let the car run by inertia.

4、 Tire pressure
When the electric vehicle runs under insufficient tire pressure for a long time, it will bring great friction resistance to the motor and double the power consumption of the electric vehicle. Long term high current power consumption will cause battery loss and shorter mileage.

5、 Load driving
At the beginning of electric vehicle design, considering the portability and efficiency, the load mass of two wheeled electric vehicle is generally 100kg, which is slightly larger than the normal weight of an adult. At ordinary times, if the load of people and goods is too heavy, the mileage of electric vehicles will also decrease. Many electric vehicles consume electricity quickly because they are not cherished every day, resulting in the situation of "small horses pulling big cars".

6、 Controller undervoltage point protection
Some controllers have poor quality, resulting in problems such as large current and parameter deviation of undervoltage value, which affect the battery power and shorten the driving mileage of electric vehicles. If the undervoltage protection point of the controller is set too high, the battery power will not be discharged completely.

To sum up, if you want electric vehicles to run farther, Xiaoxin suggests that car owners start with small daily maintenance matters, such as scientific charging, avoiding overload, driving at a constant speed, using brand electric vehicle batteries, etc. Only with proper daily maintenance can the electric vehicle ride smoothly.
