Is the battery of the battery car different from the storage capacity in winter and summer?

Yes, the capacity of lead-acid batteries is related to temperature, which is a matter of principle of lead-acid batteries.

The nominal capacity of the lead-acid battery is determined by the capacity when the ambient temperature is 25, and the battery capacity will change with the change of ambient temperature, the higher the ambient temperature, the higher the capacity, the lower the ambient temperature, and the lower the capacity. Generally, the battery capacity can be estimated at different ambient temperatures using the following formula:

CT = C25 (1-K*(T-25))C25: Refers to the capacity of 25 ah

CT: Capacity AH under the actual ambient temperature test

k: conversion factor, generally taken.

t: Actual ambient temperature.

In winter, when the ambient temperature is very low, the discharge of the battery will be greatly reduced, for example, at -15, the capacity is only about 70% of that at 25. When charging, using a matching charger will not have a greater impact on the battery, it is best to charge it for a limited time, and the general charging time should not exceed 12 hours.

When the temperature is too low, the use time of the electric vehicle should be shortened as much as possible, and it should be charged in time. If the user does not plan to use the battery car in winter, the battery must not be recharged when it is used in the next year, but should be charged every other month to ensure the power storage capacity of the lead-acid battery.

In fact, there is a difference between wood, but the internal resistance of the battery is larger in winter and the discharge current is smaller.

Different. The battery stores less power in the winter than in the summer.

Most of the batteries of electric vehicles are lead-acid batteries. One of the disadvantages of lead-acid batteries is that they are not tolerant to low temperatures. When the use environment is lower than 5 degrees, the battery capacity will gradually decrease.

Because the viscosity of the electrolyte increases at low temperatures, the ion movement is hindered, and the diffusivity decreases. In addition, the resistance to chemical reaction also increases, and the low temperature will also lead to a low utilization rate of the anode active material. For various reasons, the battery capacity will drop a lot in winter, or even more than half.

This is a normal phenomenon, and the ambient temperature is fine.

Winter electric car tips:

It is recommended that you use the kinetic energy function of the highest gear of the vehicle as much as possible in winter, especially for areas with obvious undulating roads, the braking effect of kinetic energy ** and the energy recovery income when going downhill can bring a more obvious increase in endurance in high-speed driving in winter. In fact, we also mentioned the small detail of kinetic energy ** in the previous evaluation article, and many readers also said that "there is a miraculous effect after opening".

The above content refers to People's Daily Online - low temperature warning refusal misunderstanding! Winter electric car tips:

It's not that the battery consumes more electricity in winter, but that the battery stores less power in winter, and when the temperature is low, the storage of electricity is even only 50% of the rated capacity

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.

It was winter, the weather was cold, the snow in the north was heavy, and the south was foggy, and under such temperature conditions, the electric car seemed to be about to hibernate, and the charging time was longer than before.

When the battery is charged and discharged, the chemicals in the electrodes and electrolyte will undergo a chemical reaction, and electrons will start from the electrode and pass through the electrolyte to another electrode. Therefore, when discharging, the chemicals on the electrode are consumed to discharge externally; When charging, the chemicals that were previously consumed are reduced to the electrodes by dissipating external electrical energy. Since electric vehicles will be used in different regions and under different climatic conditions, the reaction condition of temperature will affect the efficiency of the chemical reaction inside the power battery, and the chemical reaction inside the battery will become slow or even stop when the temperature is too low.

Charge frequently, do not wait for the electricity to run out before charging, it will hurt the temperature drop of the battery, which will have a direct impact on the capacity of the electric vehicle battery. In summer, it may be enough to charge once in three days, but now it may not be able to meet the use, so you need to charge it once a day. Do not wait for the electric vehicle to run out of power at all before charging, this will not only affect the normal use, but also cause damage to the battery.

The electric vehicle is not in use, and it should be charged once a month to avoid vulcanization of the battery. Before placing the electric car, the electric car should be fully charged, so that the electric car can be placed in the case of electricity, and the electric vehicle will be charged once a month, so as to avoid battery damage caused by vulcanization. Of course, sometimes the mileage of electric vehicles drops too obviously, and it is not necessarily a problem of temperature, if the drop is too obvious has affected the normal use, you can go to a regular electric car shop or repair shop to test, your battery is likely to need to be replaced.

Do not mix multiple chargers. There are many different models of electric vehicles, electric vehicles with different configurations, different battery models, and chargers are naturally different. In addition, indiscriminate use of different charger models may result in battery leakage, heat, smoke, fire, or**.

When the battery is deformed or swollen, the battery charging should be stopped immediately.

Don't use fast charging frequently, and use it fully every time you charge it.

According to the time of starting and ending charging, you can calculate how long it will take for your electric vehicle to be fully charged, and then you can select the ** when charging according to the time of charging, so that you can charge it most effectively.

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

Because the temperature is very low in winter, more electricity is required for both starting and normal driving. In winter, the ions in the battery are less active, so the electricity is consumed much faster than in summer.

Because the temperature is very cold in winter, and the battery can not be charged to a full capacity every time it is charged, it consumes a lot in the process of driving, and the performance of the battery in summer is quite perfect, so it can be fully charged.

The main reason is that the cold air in winter causes the power to be lost by itself, and the temperature difference between summer and winter is relatively large, so the gap becomes very large.

Why does the battery of an electric car drain very quickly in winter? See here for the truth.

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.

1.This completely depends on the car scene. First of all, convenient charging conditions come first.

If it's just for the daily commute, the experience is certainly superb. You don't need to heat up the car, the warm air comes quickly. In the winter in the north, the battery life will of course be discounted in half, or even quadruple.

In other words, a car with a range of 400 kilometers will have a range of 150 kilometers. But it doesn't matter, it's mainly for commuting anyway, as long as it can be charged.

2.If it's specifically for long-distance running, forget it. It is feasible in the south, but in the north, the tram is not suitable for this use now, and it can run, and you have to find a place to charge it once for more than 100 kilometers, and the experience is too poor.

Occasionally, a few trips of 100 kilometers are still no problem, and now the density of charging piles is already very high.

3.The last thing is to choose a car. When buying an electric car, you must be clear about the heavy use scenario, and you must be clear about the minimum battery life of the car in your own car use scenario.

In the northern region, it is necessary to consider the models with long battery life and a battery thermostatic system (that is, the three electric batteries have water circulation). This is destined to only consider more expensive models. There is also a category of models that are also worth considering, that is, models with fuel-assisted heating.

There is also a model, an extended-range electric car, which can also be used.

Hope, thank you.

Just look at the size of the battery in your battery car, as well as the newness of the battery.

In general, there will be a difference of about 20%.

The range will be a little longer in the summer.

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.

temperature-induced. Air temperature also has a big impact on the battery. When the ambient temperature is above 40°C or below -10°C, the battery life will be shortened.

In winter, when temperatures are low, capacity drops by 1% for every 1 degree drop in temperature. Electric vehicle batteries.

It should be stored indoors and charged indoors. If the temperature drops below 0, the battery level will drop by almost 50%. Especially lead-acid batteries.

Its endurance is a direct blow to dimensionality reduction, and the motorcycle instantly becomes a bicycle. Although electric vehicles are relatively small in size and relatively simple in structure, they also need maintenance in daily life, just like cars. The most important thing is the maintenance of the battery.

Brake abruptly and restart. Power consumption is several times higher than normal driving. In order to reduce electricity consumption in cold weather, try to maintain an even and safe ride.

In addition, long-term fast charging can also shorten the battery life of electric vehicles. The input voltage of normal charging is 50 volts, and it generally takes 10 hours to complete the charge, while the input voltage of fast charging can reach 400 volts, and the battery can be fully charged in half an hour. But that's a lot of damage to the battery!

Storage reason. When the weather turns colder, many people will put electric bikes.

Store it away and ride it up when the weather warms up. Reminder: Before storing the electric vehicle, the battery should be fully charged and guaranteed to be charged at least once a month to avoid battery damage caused by battery vulcanization. When the battery arrives in the winter, it becomes less durable.

In fact, when using an electric car in the winter, you will feel a noticeable drop in power.

It is normal for the temperature to drop and the amount of charge stored by the battery decreases. With proper use, battery performance that "sleeps" when it's cold will certainly recover in the summer. Don't remove the lid and add water just because you're in a hurry to restore the battery's performance.

Otherwise, it is easy to cause battery damage, and there are also great safety risks.

Even smaller electric vehicles can bring a lot of convenience to our travel, and the ** of electric vehicles is really cheap, so now electric vehicles are really popular and favored by consumers...
