Do you know what effect temperature generally has on the performance of lithium battery packs?

How much influence does temperature have on the capacity of lithium battery packs? It can be seen that when the discharge current is 100A, the battery capacity shrinks by 1.7% and 7.7% from 20°C to 0°C and then to -20°C. This means that even if the temperature is as low as -20°C, the battery can still reach more than 90% of the nominal capacity. It can be said that the influence of temperature on the capacity of lithium battery packs is relatively small. However, this does not mean that we can ignore the impact of temperature on the battery. According to the information provided by experts, under the condition of 5A charging current, the charging time at an ambient temperature of -25°C is 63% slower than the charging time at 25°C. After the cold weather, everyone obviously feels that the battery life of the lithium battery pack has dropped. It used to run 15km with a single charge, but now it can only run about 10km. In fact, when the lithium battery is discharged at full power, the minimum temperature is generally about 15°C. When the temperature is low, the maximum discharge current will decrease and the power will be attenuated. So the lower the temperature, the shorter the battery life. 1. Do not use the lithium battery pack in a low temperature environment. When the temperature is lower than 0℃, be careful not to charge it outdoors. You can’t charge it even if you charge it. We can take the lithium battery pack indoors for charging. -20℃, the battery will automatically enter the dormant state and cannot be used normally. Therefore, the wheel friends in the north, especially in cold places, can remove the F0 battery in a few days and use it as a power bank directly. Don't think about riding a scooter out of the snow under the snow. 2. Develop the habit of charging as you use it in winter, when the power of the lithium battery pack is too low, we must charge it in time, and develop a good habit of charging as it is used. Remember, never follow the normal battery life to pre-charge. Estimate the battery power in winter. 3. Don't stay away while charging. Remember not to charge fast-wheel products for a long time. The charging time is generally about 1.5 to 3 hours. Don't leave the vehicle in a long-term charging state for the sake of convenience. In winter, the charging environment should not be lower than 0℃, and don't leave too far when charging, to prevent emergencies, deal with it in time. 4. Please use the original charger when charging. There are a lot of inferior chargers in the market. Using inferior chargers will damage the lithium battery pack and even cause a fire. If your charger cannot be used normally, it is recommended to contact the official to purchase a regular charger to ensure the charging quality.
