Since the cold environment will increase theelectrolytic resistance of the lithium battery,the chemical reaction ratewill decrease and the current generated inside of the lithium battery will do it. is also relatively small.
At present, although there is electricity inside the lithium battery, it cannot be completely discharged. Therefore, the lithium battery will not be fully charged in winter. In the final analysis, the lithium battery cannot be completely released.
Note:
Lithium-ion batteries will reduce their capacity at low temperatures to protect themselves, so the life of phone batteries laptops may be shortened in cold environments. For example, electric cars can be driven for shorter periods in winter. But it is only temporary, and whenthe battery temperature returns to normal, as does its lifespan.
Temperature will also affect the speed of electrolyte transmission. When the temperature increases, the transmission temperature will decrease, the transmission speed will slow down, and the battery charging and discharging performance will also be affected. However, if the temperature is too high, exceeding 45°C, it will destroy the chemical balance of the lithium battery and cause side reactions.
When the ambient temperature is very high, the cell phone battery can adapt from minus 20 degrees Celsius to 60 degrees Celsius. However, when the surrounding environment is as low as zero, it is difficult to adapt to this situation, the performance will decline, and the power protection will gradually weaken, which will affect the normal operation of the mobile phone and end by driving turn off.
TheLithium batteries impact cruising range in cold winter.
The working principle of lithium-ion batteries is that the internal electrolyte changes through chemical reactions, causing a potential difference between the positive and negative electrodes to generate current. In a low temperature environment, the electrolyte moves very slowly, which affects the transfer activity of lithium ions between the positive and negative electrodes, resulting in a decrease in the charging and discharging performance of the battery.
To put it simply, in a low temperature environment, it is not that the lithium battery is really discharged, but that it is powered but cannot be released normally. According to analytical data, the capacity of ordinary lithium batteries will be reduced by 20% at zero degrees Celsius, and when it reaches minus 10 degrees Celsius, the capacity may only be approx.iron half.

Precautions for use in winter:
1 Find a warm place . to charge
When the ambient temperature is below 0℃, when charging an electric vehicle, the system will automatically heat the battery cells first. When the battery cell temperature reaches more than 5℃, it will actually. start heating the battery cells. Loading the vehicle. Some electric vehicle owners may feel that the charging speed of electric vehicles suddenly slows down in winter. This actually means that there is additional time to heat the battery cells before recharging the vehicle.
Therefore, when car owners usually charge their cars, they should try to do so in underground parking lots, closed garages and others places. This will help improve battery activity, not only reducing loss of cruising range, but also improving charging efficiency and saving time.
2, Charge for a short time before traveling
The electric car still had 60% or 70% of the power the day before, but when I started the car the next day morning I noticed that only 30% or even less power remained. Some call this situation a “power outage.” In fact, this “power outage” is not a fault, but is caused by low temperature. When an electric vehicle is driving, the battery is in a continuous discharge state, the temperature will be relatively high, and the battery voltage will also be relatively high. The remaining power of the electric vehicle displayed at this time is a normal value.
However, after being parked at low temperatures overnight, the batteryerie has cooled and the voltage has dropped. At that time, the car's system will automatically adjust the displayed power and cruising range, which creates a ". The illusion of "running out of power". In this case, you usually just need to get out in advance and charge the battery for about 10 minutes
3. Drive steadily and not in a hurry
When driving an electric vehicle, you should start slowly and avoid driving. violent such as sudden deceleration, sharp turns and sudden braking Good driving habits can effectively reduce the speed of battery consumption. The time between starting the car should not exceed 5 seconds. between restarts should not be less than 15 seconds
If the battery mileage decreases too much, go to the 4S store to check the car battery in time, replenish the electrolyte of the battery. batterye in time and adjust the electrolyte proportion.
I hope to adopt it, thank you!
