Electric vehicle batteries are afraid of freezing in winter.
When the temperature drops, the energy storage capacity of some batteries decreases. Therefore, the stored power of electric vehicles will weaken in winter, especially in environments below 25 degrees, where the reduction in stored power will be even more obvious. This requires users to strengthen care and maintenance during use to extend the service life.
Electric vehicles need to be charged for around 8 hours in winter and can be reduced to two hours in summer. Some people are not careful and have the habit of charging overnight, which will shorten the battery life. The lifespan of electric vehicle batteries also depends on the number of times consumers recharge them. The more frequent charging, the shorter the battery life.
Detailed information:
1. If the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started from time to time to charge the battery.
2. Avoid parking the car in an open-air parking lot for a long time. If parked for a long time, the battery should be removed and removed to prevent freezing and damage. .
3. Battery capacity can be reflected on the dashboard. When the ammeter pointer indicates that the battery capacity is insufficient, charge it in time.
4. The car engine is not easy to start in winter. The car starting time should not exceed 5 seconds each time andthe interval between restarts should not be less than 15 seconds.
5. When the electrolyte is depleted, distilled water or a special rehydration solution should be added. Do not use purified water instead, because purified water contains a variety of trace elements, which will have adverse effects on the body. battery.
6. Clean the battery terminals from time to time and apply special grease to protect the wiring harness. Always check accessories and connection lines on the battery.

If you compare batteries of the same voltage and capacity, it is possible that the lead-acid batteryb has a slightly longer battery life. But the lifespan of lithium batteries will be longer. Lead-acid batteries are generally used for more than two years and the battery capacity will decrease significantly. The capacity of lithium batteries decreases much more slowly and can be used for a longer period of time.
1. Disadvantages of lead-acid batteries:
Heavy weight, limited battery capacity and short lifespan. Lead-acid batteries typically last two years after 400 deep charges. deep discharges approx.
2. Disadvantages of lithium batteries:
The production cost of lithium batteries is high, the production equipment is expensive, and labor costs account for about 40% of production costs. the price is about three times that of lead-acid batteries. At the same time, lithium batteries are not recyclable and cannot be recycled.can only be thrown away when they are worn out. There is another important issue that lithium batteries pose fire and explosion hazards, especially when consumers are unknowingly deceived by profiteers and buy substandard lithium batteries. In electric vehicles, the sealing conditions are not very good and they are prone to moisture, resulting in poor contact. and other reasons that cause security issues.
