As soon as winter comes, do many people who ride electric vehicles find that it's easy for them to run not far in winter, and the electricity will be gone soon after not riding for a long time, do you know what causes it? Do you know what's the culprit for the short distance of electric vehicles in winter?
1. Lower temperatures can cause a drop in the mileage of electric vehicles.
This is a normal phenomenon. After the year, the temperature will rise and the driving mileage will recover. The most suitable temperature for electric vehicle battery is 25-35 degrees. The lower the temperature, the weaker the battery's charging and discharging ability. If the temperature drops to 0 ℃ or below, the driving mileage of electric vehicles can be shortened by one third to one half. If the ambient temperature reaches - 15 ℃, the battery will almost lose the ability of charge and discharge. It is a normal phenomenon that the weather suddenly turns cold in winter and the driving mileage of electric vehicle drops, not necessarily because of electric vehicle or battery failure.
2. The load quality has a great influence on the driving mileage of electric vehicles.
The electric vehicle is a light and efficient design. The load weight of the two wheel electric vehicle is usually 100 kg, which is slightly larger than the normal weight of an adult. If the load of the human load is too heavy, the driving mileage will also drop a lot.
3. The driving speed also has a great influence on the driving mileage of electric vehicles.
We all know that the higher the speed of the car, the higher the fuel consumption, the same is true for electric vehicles. There is also an economic speed. Generally, the economic speed of 350 Watt and 500 Watt motors is 20 and 30 kilometers respectively. The mileage data given by the manufacturer is also tested within the economic speed, and we usually use the highest speed when driving electric vehicles, so we often fail to reach the longest mileage declared by the manufacturer.
4. Other common reasons.
For example, the driving resistance caused by insufficient tire air pressure and low air pressure is too large, the brake of electric vehicle is too tight or the brake is not fully returned, the road condition is not good, resulting in frequent acceleration and deceleration and braking, too many ramps, driving against the wind, etc.
5. Be misled by some customers.
Before, a customer told me that his 48v12ah battery could run 150 miles, not to mention whether it was true or false. If the customer required batteries according to this standard, it is estimated that all electric vehicles of this type could not reach. Some of the customers like to exaggerate, some of them believe it, so there will be problems with the car.
The mileage of electric vehicle is not only determined by the battery, but also reflects the battery capacity of electric vehicle and the matching of motor and controller. It is also one of the reference standards for users to evaluate the quality of an electric vehicle. For many users, especially the new electric vehicle, if the mileage can not meet their own requirements, it is often attributed to the poor battery quality or electric vehicle quality problems, and just ignored the use of the environment on the driving mileage of the electric vehicle this important factor. The battery problem is mainly reflected in the fact that the driving mileage is significantly shorter than before under the condition of constant use environment. Customers should take this experience standard as a reference to find out the battery with real problems in time.
