Why is the electric car not far away when it is cold?

Recently, there have been frequent customer reactions. It’s not long before the electric car is bought. It’s not a problem with the battery. In fact, most of the time, customers have little knowledge about electric vehicles and batteries. There are even some understandings. Misunderstanding, many customers have overlooked the following factors.

1. The temperature drop will cause the mileage of the electric vehicle to drop. This is a normal phenomenon. After the year, the temperature will rise and the mileage will be restored. The optimum temperature for electric vehicle batteries is 25 to 35 degrees, the lower the temperature, the weaker the battery charge and discharge capacity. If the temperature drops to 0 degrees or less, the mileage of electric vehicles can be shortened by one-third to one-half. If the ambient temperature reaches minus 15 degrees, the battery almost loses its charge and discharge capacity. Seeing that it enters the winter, the weather suddenly becomes cold. It is normal for the electric vehicle to travel down. It is not necessarily the electric vehicle or battery failure.

2. The load quality has a great influence on the mileage of electric vehicles. The electric vehicle is light and efficient. The weight of the two-wheeled electric vehicle is usually 100 kilograms, which is slightly larger than the normal weight of an adult. If the load of the manned load is too heavy, the mileage will drop a lot.

3, the driving speed has a greater impact on the mileage of electric vehicles. We all know that the higher the speed of the car, the more fuel-efficient, the same is true for electric vehicles, and there are economic speeds. The economic speeds of the 350-watt and 500-watt motors are usually 20 and 30 km respectively. The mileage data given by the manufacturer is also tested at economic speed, and we are usually used to the highest speed, so we often fail to reach the longest mileage claimed by the manufacturer.

4. Other common reasons besides this. For example, if the tire gas is insufficient and the air pressure is too low, the driving resistance is too large. The brake of the electric vehicle is too tight or the brakes are not fully returned. The road condition is not good, causing frequent acceleration and deceleration and braking, too many ramps, and driving against the wind.

5. Misleading by some customers. In the past, a customer told me that his electric vehicle 48V12AH battery can run 150 miles. It is true or false to say that if he asks for the battery according to this standard, it is estimated that all this type of electric vehicle cannot be reached. Some customers like to exaggerate their words, and some customers believe that it is true, so there is a problem with the car without problems.

The driving mileage of an electric vehicle on a single charge is a comprehensive manifestation of the electric vehicle battery capacity and the matching of the motor and the controller plus the use environment, not only determined by the battery. It is also one of the reference standards for users to evaluate the quality of an electric vehicle. For many users, especially new electric vehicles, if the mileage does not meet their own requirements, it is often attributed to the poor quality of the battery or the quality of the electric vehicle. It just ignores the importance of the use environment on the mileage of electric vehicles factor. The battery problem is mainly reflected in the fact that the driving range is significantly shortened compared with the previous one. The customer should use this experience standard as a reference to detect the battery with real problems.
