how to treat lithium batteries correctly in winter

how to treat lithium batteries correctly in winter?

1. Do not use lithium batteries in low temperature environments The temperature has a great influence on lithium batteries, the lower the temperature, the lower the activity of lithium batteries, which directly leads to a significant reduction in charge and discharge efficiency, so in general, the working temperature of lithium batteries is between -20 degrees and 60 degrees. When the temperature is lower than 0 ° C, be careful not to charge outdoors, you can not charge it, we can take the battery indoors for charging (note, must stay away from flammable materials!!! When the temperature is lower than -20 ° C, the battery will automatically enter the sleep state and cannot be used normally. So the north is especially cold places for users. If there is really no indoor charging conditions, it is necessary to make full use of the residual heat when the battery is discharged, and charge it in the sun immediately after parking to increase the amount of charging and avoid lithium precipitation.

2. Develop the habit of charging as you go In winter, when the battery power is too low, we must do it in time, develop a good habit of charging as you go, and remember, never estimate the battery power in winter according to the normal battery life. In winter, the activity of lithium batteries decreases, which is very easy to cause overdischarge and overcharge, which affects the service life of the battery at light and causes combustion accidents at worst. Therefore, in winter, we should pay more attention to charging in a shallow and shallow charge. In particular, do not park the vehicle for a long time in a way that is always charged to avoid overcharging.

 3. Do not stay away when charging, remember not to charge for a long time Do not keep the vehicle in a state of charge for a long time for the sake of convenience, so that it can be fully loaded and unplugged. The winter charging environment should not be lower than 0 °C, and when charging, do not leave too far away to prevent unexpected situations from occurring, and deal with them in time.

4. Use a special charger for lithium battery when charging The market is flooded with a large number of inferior chargers, and using inferior chargers can cause battery damage and even cause fire. Do not be greedy for cheap and unguaranteed products, let alone use lead-acid battery chargers; If your charger does not work properly, stop using it immediately.

5. Pay attention to battery life and replace it in time Lithium batteries have a life, different specifications and models of different battery life, coupled with improper daily use, the life of the battery ranges from several months to three years, if the car has power failure or abnormal battery life, can not be charged and discharged when please contact lithium battery maintenance personnel in time to deal with.

6. Leave spare electricity for winter In order to be able to use the vehicle normally next spring, if you do not use the battery for a long time, remember to charge 50%-80% of the charge, and unload and store it from the car, and charge it regularly, about once a month. Note: The battery must be stored in a dry environment.

7. Place the battery correctly Do not immerse the battery in water, or keep it wet; Do not stack the batteries for more than 7 layers, or invert the battery orientation.
