I believe many of them have discovered that when riding an electric bicycle in winter, the battery life is obviously much shorter than in summer, and sometimes even the battery data display is inaccurate. Why is this? Is the battery broken? In fact, this is all due to the influence of low temperature.ESS battery machine Today, we will come to popularize science and education on the causes of the problem of battery life development of electric vehicles in winter, and how to effectively solve it.
First, we need to understand the chemical reactions of batteries at low temperatures. The battery of an electric car is made up of many cells, each of which produces electricity through a chemical reaction.Solid-state batteries The rate of chemical reactions is closely related to temperature. Generally speaking, the higher the temperature, the faster the chemical reaction, and the higher the discharge efficiency of the battery; the lower the temperature, the slower the chemical reaction, and the lower the discharge efficiency of the battery. Therefore, when the temperature drops, the power output of the battery decreases and the battery life decreases. Besides temperature, another factor is cold air. The density of cold air is higher than that of hot air, which creates greater resistance to the driving of electric vehicles and increases the power consumption and battery consumption rate of electric vehicles. At the same time, cold air will increase the resistance of the circuit, resulting in low battery charging and discharging efficiency and short battery life.
So, faced with the problem of declining battery life of electric vehicles in winter in my country,sodium ion battery what solutions do we need? Here are three practical tips:
Battery insulation treatment
When the temperature is low in winter, the development of battery chemical reactions slows down, which directly leads to the acceleration of battery discharge. In order to slow down this social phenomenon, we can use different insulation techniques on batteries.
A common method is to purchase a special battery insulating bag. This kind of bag is well designed and can effectively prevent the impact of cold air on the battery, thereby extending battery life.
In addition, if you think it is not economical to buy a battery insulation bag, you can also wrap the battery with insulation materials such as foam plastic, which can also achieve the insulation effect. Alternatively, we can take the batteries indoors when the electric vehicle is not in use.
Reasonable charging timing selection
Reasonable design and choosing your own charging timing is also an important way to extend battery life. In winter, the temperature will be relatively high at noon or afternoon. Charging at this time can effectively improve the charging efficiency of the battery, and at the same time, avoid shortening the battery life caused by low-temperature charging. In addition, try to avoid charging in a low temperature environment for a long time, as this will accelerate the aging process of the battery.
Replacing low-temperature batteries for electric vehicles
There are some low-temperature-resistant batteries on the market specifically designed for winter. Their characteristic is that the chemical reaction speed of the battery will not be greatly affected in low-temperature environments, so they can effectively improve the endurance of electric vehicles in winter. Although the price of this battery will be slightly higher, considering the convenience it can bring us in winter, it is undoubtedly worth the investment.
In addition, regular inspection and maintenance can also extend the battery life. Our country needs to regularly check the battery cables, screws and other parts to ensure that they are in a good state of development. If these problems are not found, they should be repaired promptly and effectively.
