Can electric vehicle lithium battery packs be charged in low temperatures during winter? In winter, the energy storage capacity of electronic devices gradually weakens. Before going out, the phone's battery level is 100%, but immediately drops to 50% after going out. In low-temperature environments, the battery capacity of electric vehicles will also be greatly reduced, leading to a decrease in mileage. Can electric vehicle lithium battery packs be charged in low temperatures during winter? Below, the lithium battery manufacturer will analyze for you!

Can electric vehicle lithium battery packs be charged in low temperatures during winter?

Electric vehicle lithium battery packs can be charged in low temperatures during winter. When the temperature is below 15 degrees Celsius, the storage capacity of the electric vehicle battery will decrease, while at 25 degrees Celsius, it is the time when the electric vehicle battery can achieve the most perfect storage and power generation capacity. So, in a low temperature state, both the charging and storage capacity of the battery will decrease. If you need to charge it in winter, it is best to leave the car indoors. Generally, charging takes 8 to 10 hours, which is one night.

At present, there are mainly two types of electric vehicle battery technologies available on the market, namely ternary polymer lithium batteries and lithium iron phosphate batteries. Their performance varies when facing low temperatures, but in reality, regardless of the battery technology, there is a decline in battery performance when facing low temperature environments.

In order to maintain battery performance, most electric vehicle products on the market are equipped with lithium battery pack constant temperature systems. When the working temperature of the battery is too low, the battery management system will convert a portion of the electricity into thermal energy to heat the entire battery pack. If electric vehicles are not used for a long time, low temperatures can cause performance degradation of battery components, which is not conducive to extending their service life. So, batteries are really afraid of being "cold" and should be avoided for long periods of time at low temperatures as much as possible.

At low temperatures, lithium-ion batteries generally suffer from poor charging acceptance and insufficient charging. In this case, it is necessary to increase the charging voltage and extend the charging time, and take insulation and antifreeze measures to ensure sufficient charge and extend the battery's service life.

It is recommended to charge the battery frequently and not wait until it is fully charged. It is better to charge the lithium-ion battery halfway through. In addition, to prevent the battery from freezing, electric vehicle batteries can be placed in rooms with higher temperatures when not in use, and should not be placed directly on the ground. If the battery cannot be disassembled, the electric vehicle can be parked indoors overnight.

How to maintain electric vehicle lithium batteries in winter

1. Do not use lithium batteries in low temperature environments

When the temperature is below 0 ℃, be careful not to charge it outdoors. Even if you charge it, you won't be able to charge it. We can take the battery indoors for charging. When the temperature is below -20 ℃, the battery will automatically enter sleep mode and cannot be used normally. So, for those who are particularly cold in the north, they can dismantle the battery and use it directly as a power bank after a while.

2. Develop the habit of using and charging at any time

In winter, when the battery level is too low, we should charge it in a timely manner and cultivate the good habit of charging as needed. Never estimate the winter battery level based on the normal range of the lithium battery pack.

3. Please do not stay away from charging and remember not to charge for a long time

The charging time for fast wheel series products is generally around 1.5-3 hours. Do not keep the vehicle in a charging state for the sake of convenience, just fully charge and unplug it. The winter charging environment should not be lower than 0 ℃. When charging, do not leave too far away to prevent unexpected situations and handle them in a timely manner.

4. Please use the original charger when charging

The market is flooded with a large number of low-quality chargers, and using low-quality chargers can cause battery damage and even cause fires. If your charger cannot be used normally, it is recommended to contact the official to purchase a legitimate charger to ensure charging quality.

5. Pay attention to battery life and replace it in a timely manner

Electric vehicle lithium battery packs all have a lifespan, and the lifespan of batteries varies with different specifications and models. In addition, improper daily use can result in a lifespan of several months to three years. If your scooter or balance car experiences a power outage or abnormally short battery life, and cannot be charged or discharged, please contact the official for battery replacement in a timely manner.

6. Leave some extra electricity for the winter

In order to use the vehicle normally next spring, if the battery is not used for a long time, remember to charge 50% to 80% of the battery, remove it from the vehicle for storage, and charge it regularly, about once a month. Attention: Batteries must be stored in a dry environment.

The above is the correct charging and maintenance method for lithium-ion battery electric vehicles in winter. With the increase of usage time, the performance wear, aging, and corrosion of functional components may gradually reduce the driving safety performance. Correct charging and good maintenance habits can ensure the safe driving of electric vehicles.
