Why can't electric cars go far in cold weather?

Recently often have customer reaction, electric car bought how to ride for a while not long not far, is not the battery has a problem, in fact, most of the cases are customers to electric car and battery related knowledge too little, even there are some understanding of the error. Many customers ignore the following factors.

1. Lower temperature will lead to lower mileage of electric vehicles. This is a normal phenomenon, after the year the temperature rises, the mileage will be restored, the most suitable temperature for electric vehicle battery is 25 ~ 35 degrees, the lower the temperature, the weaker the battery charging and discharging ability. If the temperature drops to 0 degrees or below, the range can be reduced by one-third to one-half. If the ambient temperature reaches 15 degrees below zero, the battery almost loses its ability to charge and discharge. Seeing the winter, the weather suddenly cold, electric vehicle mileage reduction is a normal phenomenon, not necessarily electric vehicles or battery failure.

2. Load quality has a great influence on the mileage of electric vehicles. Electric cars are designed to be lightweight and efficient. Two-wheeled electric cars typically weigh 100 kilograms, slightly more than the normal weight of an adult.

3. The driving speed has a great influence on the driving range of electric vehicles. We all know that the higher the speed of cars, the higher the fuel consumption. The same is true for electric cars. There is also an economic speed. The range data given by the manufacturer is also tested within the economic speed limit. However, we are usually used to using the maximum speed when driving electric vehicles, so we often fail to achieve the maximum range claimed by the manufacturer.

4. Other common reasons. For example, the driving resistance caused by insufficient tire air and low air pressure is too large, the braking adjustment of the electric vehicle is too tight or the brake is not completely returned, the road condition is bad, resulting in frequent acceleration, deceleration and braking, too many ramps, driving against the wind and so on.

5. Misled by some customers. Once a customer told me that his electric vehicle 48V12AH battery can run 150 miles, not to mention his words is true or false, if the customer according to this standard requirements of the battery is estimated that all this type of electric vehicles are not up to. Some customers like to exaggerate, and some customers believe it, so the car is not a problem.

The range of a single charge of an electric vehicle is a comprehensive reflection of the battery capacity of an electric vehicle, the matching quality of the motor and the controller, and the operating environment. It is not only determined by the battery. It is also a reference standard for users to evaluate the quality of an electric vehicle. For many users, especially the new electric vehicles, if the mileage does not meet their own requirements, it is often attributed to poor battery quality or electric vehicle quality problems, and just ignore the use of the environment on the electric vehicle mileage impact this important factor. Battery problems are mainly reflected in the use of the same environment, the mileage than before has greatly shortened, customers should take this experience as a reference standard, the real problem of the battery in a timely manner.
