Recently many customers reflect that electric cars bought not long, why it can not drove far, whether there was something wrong with the battery, In fact, most of the time, customers have too little knowledge about electric vehicles and batteries. There are even some misunderstandings. Many customers have overlooked the following factors.
1. The temperature drop will cause a decline in electric vehicle mileage. This is normal phenomenon, after the year, temperature will rise and mileage will resume, the optimum temperature for electric vehicle batteries is 25 to 35 degrees. The lower the temperature is, the weaker the battery charge and discharge capacity. If the temperature drops to 0 degrees or less, the mileage of the electric vehicle 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. Winter is coming, the weather suddenly becomes cold. It is normal for the mileage of the electric vehicle to fall. It is not necessarily the malfunction of the electric vehicle or the battery.
2. The loading has a great influence on the mileage of electric vehicles. The electric vehicle is design for light and efficient. The loading 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 be greatly reduced.
3. The driving speed also has a great influence 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. Regardless of true and false, if according to this standard, all this type of electric vehicle cannot be reached it. 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 performance 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 car. For many users, especially new electric vehicles, if the mileage does not match 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. The battery problem is mainly reflected in the fact that the operating environment is the same, when the mileage is much shorter than before, customers should use this experience standard as a reference to detect the battery with real problems.
