After the winter solstice, it enters the number of cold days, the cold wind is sluggish, the snowflakes are fluttering, and many areas begin to have a large temperature and snowfall weather. With the significant cooling, many electric vehicle owners have found that electric vehicles are becoming more and more unpopular
In fact, it is a normal phenomenon that electric vehicles cannot run far when the weather is cold, and the endurance of electric vehicles decreases.
Generally speaking, the optimal charging and discharging ambient temperature of the battery is 20-30. In this temperature range, the battery has the highest charging and discharging efficiency and the best effect. When the temperature drops, the battery's ability to store electricity decreases. When the temperature is below 15, the drop in battery capacity will be more pronounced, and for every 1 degree drop in temperature, the usable capacity will drop by 0Around 8%.
The weather is cold, and the range of electric vehicles will inevitably shrink, but doing the following things well can also avoid range anxiety to a certain extent.
01 Charge lightly to avoid recharging after running out of power.
When the battery level is less than 30%, it should be charged in time. As the temperature drops, so does the battery capacity. Even if it is the same battery, the capacity is not the same in summer and winter.
Therefore, try to do shallow charging in winter, and increase the charging frequency appropriately in winter.
02Avoid charging in the open air and pay attention to the dampness of the electric vehicle line.
On the one hand, open-air charging will be affected by rain and snow, resulting in the wiring or battery of the electric vehicle being damp and malfunctioning. When the external temperature is too low, it is easy to make the battery not fully charged, resulting in power loss, and the battery is easy to vulcanize over time, affecting the battery life.
Therefore, when charging an electric vehicle in winter, it is best to choose a relatively constant temperature environment.
03 Special car allocation, do not mix chargers at will.
The charger must use a matching charger, not a mixed charger, whether it is a lithium battery or a lead-acid battery, the original charger must be used for charging, otherwise it is easy to cause damage to the battery due to the current mismatch, resulting in unsatisfactory battery charging or overcharging.
04Maintain good riding habits.
Daily riding, developing good riding habits is also a kind of protection for the battery.
When starting, do not tighten the handlebar door all the way down. It is important to know that the power consumption of instantaneous acceleration at the start is several times higher than that of ordinary driving, so accelerate as slowly as possible.
Use the emergency brake sparingly. When riding, try not to brake suddenly, which will cause a large amount of power consumption in an instant, shorten the mileage of the electric vehicle, and protect the battery is also very unfavorable.
Maintain a constant speed. Do not accelerate or decelerate suddenly during the driving of the electric vehicle, it is best to maintain a constant speed, so that the operation of the motor is relatively stable, and the power consumption of the battery is relatively low, which helps to extend the driving distance.
When traveling in cold weather, you must remember to do a good job of keeping warm!
If you choose other ways to travel in the cold winter, please charge the long-term parked electric vehicle every half a month or so, which can avoid sulfation of the battery plates, causing battery power loss and affecting the battery service life.
