How big is the gap between EV batteries in winter and summer?

In winter and summer, the difference in battery availability is mainly due to the difference in temperature. At present, electric vehicles use lead-acid batteries, the best working environment temperature of this battery is 15 — 40, below this temperature, the battery storage power will be reduced, the lower the temperature, the more obvious the drop in power, due to the low temperature in winter, so the driving distance of the electric vehicle will also be reduced, and the phenomenon will be restored when the temperature rises, therefore, in order to ensure the normal use of electric vehicles, the easiest way is for users to charge in time.

Precautions for using electric vehicle batteries in winter.

1. Avoid instantaneous high-current discharge.

When the electric vehicle starts or goes uphill in winter, it should be assisted by humans to avoid instantaneous high-current discharge. In addition, when the electric vehicle is idle, the battery should be stored sufficiently to prevent power loss, the longer the power loss, the more serious the battery damage, the electric vehicle after use, the battery should be charged frequently, do not charge the battery after it is completely used up.

2. Battery storage.

If the vehicle is parked in the open air or cold storage for several weeks when not in use, the battery should be removed and stored in a warmer room to prevent the battery from being damaged by freezing, and it should not be stored in a state of power loss. If not in use for a long time, charge it once a month.

3. Clean the battery.

It is also important to clean the battery's binding posts and protect them with special grease to ensure reliable start-up and extend battery life.

Lithium batteries have an impact on the range in the cold winter.

Lithium-ion batteries work on the principle that the electrolyte inside changes through a chemical reaction, and a potential difference occurs at the positive and negative electrodes to produce an electric current. In a low-temperature environment, the electrolyte moves quite 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 dead, but that there is power but cannot be released normally. According to analysis 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 about half.

Extended Information: Precautions for Winter Use:

1. Find a warm place to charge.

When the ambient temperature is lower than 0, charge the electric vehicle, the system will automatically heat the battery cell first, and when the temperature of the battery cell reaches more than 5, it will really start charging the vehicle. Some EV owners feel that charging their EV in the winter suddenly slows down, which is actually an extra time to heat up the battery cells before charging the vehicle.

Therefore, when the car owner usually charges the car, he should try to choose the underground parking lot, closed garage and other places. This helps to improve the activity of the battery, which not only reduces the loss of range, but also improves the efficiency of charging and saves time.

2. Charge the battery for a short time before traveling.

The day before, the electric car was still 60 or 70 percent charged, but the next morning it was only 30 percent or less charged. Some people call this situation "running electricity". In fact, this kind of "running power" is not a failure, but a fault caused by low temperature.

In the process of driving the electric vehicle, the battery is in a state of continuous discharge, the temperature will be relatively high, and the voltage of the battery is relatively high.

However, after being parked in a low temperature state for a whole night, the battery has cooled down and the voltage drops, at which point the car's system will automatically adjust the displayed power and range, which creates an illusion of "running power". In this case, you generally only need to go out in advance and charge the battery for about 10 minutes.

3. Drive steadily and don't be in a hurry.

When driving an electric vehicle, you should accelerate slowly and avoid intense driving methods such as deceleration, sharp turns, and sudden braking. Good driving habits can effectively reduce the rate at which the battery drains power. The time to start the car should not exceed 5 seconds each time, and the interval between starting again should not be less than 15 seconds.

If the battery mileage drops too much, you should go to the 4S store in time to check the battery of the car, replenish the electrolyte of the battery in time, and adjust the specific gravity of the electrolyte.

Hope, thank you!

The president revealed: With the same battery, why does the electric car not run as far in winter as in summer?

Strengthen maintenance and maintenance during use to prolong life. It is understood that when the temperature drops, the power storage capacity of some batteries will decrease. As a result, the storage capacity of electric vehicles will weaken in winter, especially in environments below 25 degrees Celsius.

This requires users to strengthen maintenance and maintenance during use to prolong the service life. Maintenance and storage require skills

1. Normally, for the charging time of electric vehicles, if the charging time exceeds the normal 8 hours and reaches 12 hours or even longer, this will not only shorten the battery life of the electric vehicle, but also more likely to lead to hidden dangers due to overcharging. Therefore, we once again remind the majority of electric vehicle users not to be too troublesome to charge overnight.

2. The best solution is not to charge the electric vehicle for more than 10 hours, that is, it is not enough to charge: generally 6-8 hours in summer and 8-10 hours in winter. According to relevant data, when the battery of the electric vehicle reaches 70%-80%, it is best to charge it at this time, of course, the battery can also be overdischarged.

Vice versa. > pay attention to the use of electric vehicles.

According to professionals, electric vehicles need to be kept charged for about 8 hours in the winter and two hours in the summer. Some citizens do not pay attention and are accustomed to charging the battery overnight, which will shorten the life of the battery. The lifespan of an EV battery also depends on the number of times the consumer charges it, and the more often it is charged, the shorter the battery's lifespan will be.

Professionals also recommend that consumers try to use the original charger as much as possible, charge it in time, and do not wait for the power to fall below 30% or the alarm light is on before charging. When the electric car starts, do not start the battery immediately, the most appropriate way is to ride the assist.

The lead-acid battery used in electric vehicles has certain requirements for temperature, and the discharge response is slow when the weather is cold in winter, and the battery capacity decreases by 1% for every 1 degree drop in temperature below zero, and it returns to normal after the temperature rises. So it doesn't feel durable.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, dear, the exclusive technician of the car master will serve you, attentively, carefully and attentively answer your car questions, find solutions and solutions to the corresponding problems for you, and will definitely provide you with satisfactory service! Hope mine can help you! Dear, hello, the battery of the battery car in winter is not resistant to application, the main reasons are as follows.

First, the battery attenuation caused by the low ambient temperature is a common phenomenon in electric vehicle batteries. Second, in a low-temperature environment, the rechargeable battery is not fully charged at all, so the battery will not be durable. Third, you can measure the normal discharge voltage of the battery, if it is not less than ten, this means that the battery is fine.

The temperature drop will have a certain impact on the capacity of the battery, but it is not the heat consumed, but the reduction of the active substances in the battery. 25 degrees Celsius.

The temperature has not dropped by one degree, and the capacity has dropped. But past winter, the battery will be fine.

In winter, the liquid will solidify.

The battery fluid also solidifies.

In this way, the contact between the battery fluid and the lead plate is not uniform enough.

As a result, the electrolysis effect is not good, so even if the charging time is sufficient, the battery use time is still very short.

If some of the battery liquid solidifies badly, it will not flow, and it will not be able to contact the lead plate, and there will be no electrolysis effect.

The discharge time will be much shorter.

In summer, there is little damage to the battery. The battery is best in spring, summer and autumn throughout the year, the temperature difference at this time is smaller, the battery is used and maintained normally, and the electrolyte inside is more active. The worst season is winter.

Therefore, when the winter is coming, the electric vehicle should check whether the battery is losing power in advance, whether it needs to add electrolyte, and do a routine check that the weather suddenly becomes cold and will not lose power because of the cold, and the car cannot be started. If you don't use the car for a long time, you can start the car for about two weeks to properly replenish the electric energy.

Under normal circumstances, when the temperature is about 25 degrees, the lead-acid battery can be charged and discharged to the maximum extent; However, when the temperature drops below 10 degrees Celsius, the amount of electricity stored in the lead-acid battery decreases. Below 0 kWh, the amount of electricity stored will be reduced by 30% or more. Therefore, even if you buy a new electric car, in most cases, the battery life is not good in winter, that is, you can't go far.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Winter is just a little colder.

It is also charged normally and used normally, but the battery here may not store as much electricity in the winter as it does in the hot day and in the summer, and the mileage will be reduced a little This is normal.

It is recommended that you do not let the battery lose too much power and charge it in time, otherwise it will easily lead to low battery life.

Is there a difference between lithium battery electric vehicle battery use in winter and summer.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, and dedicated to answering Zheng Zhaoqing's car problems for you, and finding solutions and solutions to the corresponding problems for you! The relevant scheme is as follows: there is no difference between the winter chain sail is just a little colder, it is also normal charging, normal use, but in winter, the battery can be shouted before the electricity can be stored not as much as in the hot day in summer The mileage will be reduced Some This is normal It is recommended that you do not let the battery lose too much power and charge it in time, otherwise it will easily lead to low battery life.

Excuse me, the battery.

Yes, lithium batteries are also one of the types of batteries, and there are no special requirements for ordinary use, and there is no distinction between summer and winter.
