Are batteries afraid of the cold in winter? – Semco university

Introduction

Do you often let your car “test” in danger? In fact, it’s cold, and it’s easy to “freeze” the battery when going out on an electric bike. Therefore, if you want to be more secure when you go out, you need to know about battery antifreeze (batteries afraid of the cold in winter). With the sudden drop in temperature recently, many friends riding electric bikes have found that the car will run out of power halfway if it can’t run far. So, what is the cause of battery power loss and frequent charging?

In fact, the cold temperature in winter and the rapid change of the battery power of electric vehicles are not a quality problem mistaken by everyone. Because it is very likely that your electric car battery is “frozen”. At present, the types of lead-acid and lithium electric vehicles in domestic electric vehicles are equally divided into autumn, especially for models of lead acid batteries, which are relatively sensitive to temperature.

Because the optimal operating temperature environment of lead-acid batteries is 25 degrees Celsius, the weather is cold in winter. When the temperature drops, the activity in the lead-acid battery decreases, resulting in an increase in resistance, the battery capacity will decrease, and the charging effect will decrease, which will eventually lead to a significant decrease in the storage capacity of electric vehicles.

Therefore, in cold winter, it is normal for the battery life to end early in the long run. So, how can we avoid “testing” electric vehicle batteries on the dangerous edge of cold temperatures? Here are 4 tips for battery antifreeze for electric vehicles.

Change the Battery as you want

As the ultimate pain point for electric vehicle users, battery life has always been a topic of concern to everyone. Therefore, in winter, once your electric car finds that the battery is running out, it must be charged in time to avoid losing power.

In addition, if possible, it is best to keep the battery of the electric vehicle fully charged to avoid power halfway or power loss in the cold weather, resulting in becoming a “road killer” and creating potential safety hazards

It is also Necessary for Batteries to be Afraid of Cold & Warmth

When traveling in winter, people will feel cold, not to mention electric vehicles. As the core power component of electric vehicles, the performance and temperature of the battery are closely related. Among them, the best ambient temperature of the battery is 25 degrees Celsius

In cold winter temperatures, it is necessary to increase the charging voltage of the battery of electric vehicles, ensure the charging time, avoid long-term charging, and keep the battery warm and anti-freeze.

Cycling helps Extend Battery Life

Generally speaking, when you travel to and from work in the city, the section of the road will be relatively stable. However, if you encounter uphill and downhill sections in winter, you need to skill fully accelerate or slow down to avoid frequent braking acceleration.

Especially in the downhill section, use inertia as much as possible to cut off the power in advance to keep gliding. When encountering a red light, you can enter the taxi in advance to reduce the battery burden and ensure that the battery is power-saving, so that electric vehicles can be used in winter. The power ser‐ vice life is longer.

Learn About the Water Proof and Moisture – Proof Battery

In winter, we often find that if we wear glasses, you will have a layer of water vapor when you enter the house from the cold outdoors. Similarly, when the battery of an electric vehicle enters the room from an outdoor low temperature, the surface of the battery will also frost.

Conclusion

Therefore, at this time, it is necessary to deal with the frost of the battery in time, dry it in time, avoid water and moisture prevention, and avoid short circuit caused by moisture of components, which will lead to the risk of battery leak‐ age. You should wait until the battery is dry before charging.

Remember the above four battery antifreeze techniques will definitely make your car, When you travel in winter, the battery power is guaranteed, which effectively avoids the embarrassment of running out of power half‐ way, and travels safer in winter.
