How many kilometers does it take for a car to fully charge the battery at one time?

1. Under normal circumstances, the trolley engine can be charged for more than 60 minutes at more than 1500 rpm, and then charged at more than 1900 rpm for more than 60 minutes, and the battery with half of the power can be basically fully charged.

2. The battery power is less than half, that is, when the voltage is lower, the car is difficult to start, and the battery warning light is on.

3. When the car is driving on the highway, the battery is basically full after 2 hours without turning on high-power electrical appliances, such as air conditioners and headlights.

4. In actual use, it is impossible for the battery to be truly full.

Under normal circumstances, if the engine of the trolley is kept above 1500 rpm, it will take about 60 minutes. If you keep it above 1900 diamonds and charge it for more than 60 minutes, you can basically fully charge half of the battery. If the car is on the highway for two hours, the battery will basically be full.

If it goes from 0 to 100% power, it generally takes 6 to 10 hours (battery parameters vary depending on the vehicle), but it generally does not need to be fully charged at one time, because as long as the car can be started, the starting engine will continue to charge the battery.

The car will charge the battery while driving, and the battery must be fully charged, which can only be fully charged after an hour of high-speed driving.

Because every time our car is ignited, we need to discharge the battery to generate electric sparks to use electricity to ignite, so we need to consume a lot of electricity every time we ignite, but many drivers don't know how much electricity the car needs to be ignited once? We also know that the car is moving.

According to the amount of battery power, if the lack of power is serious, it is recommended to disassemble the battery and fully charge it before installing it.

Car batteriesWhen there is no power, the car battery can basically be fully charged after running at high speed for more than an hour, so the battery can be kept in the best condition.

The battery on the vehicle is an important part of the power supply to the electrical equipment in the car, if the battery is out of power, not only the car can not be ignited, but the electrical equipment in the car can not work normally. The so-called battery is dead, not that the voltage of the battery has dropped to 0V, but that it has dropped. At present, the nominal voltage of the car battery is 12V, and the measured voltage should be between in the case of no load.

Car battery precautions.

After the first battery of a private car is worn out in normal use, even if it is replaced with a new battery of the same quality, the service time will be shorter than that of the previous battery, mainly because the performance of other related assemblies of the vehicle is reduced, such as the performance of the starter and generator, resulting in an increase in power consumption and insufficient charging, which shortens the life of the battery.

Therefore, if you want to extend the service life of the battery, it is necessary to maintain the overall performance of the car well, not over-discharge, and not to make the battery often in a state of power loss.

How long does it take for the car to be fully charged if it doesn't drive for a week?

If the car is left unturned for a week, the battery loss is not large. Generally, the dark current of the car is between 10-30mA, so the power consumption is about 24h a week.

That is to say, a battery with a capacity of 60ah, after the car is parked for seven days, consumes 5ah, less than one-tenth. The initial charging current of the car generator is more than 15 amps, and it can be fully charged in 10-20 minutes. But sometimes after the battery is exhausted, you can start the vehicle again after driving for ten minutes or even a few minutes, but at this time it can only be started tightly!

The battery is not fully charged!

There is no need for special maintenance during the normal use of car batteries, especially now many maintenance-free batteries are used, as long as there is no leakage, there is basically no need for special maintenance. Usually pay attention to check the battery connection, whether there is oxide in the head of the battery pile, if there is green oxide, disassemble the battery clip, and you can use clean water to clean the oxide on the battery pile. Then clean the clip, and if it is serious, you can use fine sandpaper to polish it to brightness, or replace it with a new clip, and finally install the battery clip.

After the car is parked for a long time, first open the key to look at the dashboard, you can press the horn to see the power storage. If the horn sound is crisp and does not lose power, no problem. If the horn is hoarse, you need to take the electricity.

After landing, if it is a normal driving with automatic transmission, it is fine. After driving for more than 2 hours, it can be charged and satisfied, and there is no need to disassemble and charge.

Nowadays, many car electrical appliances are more, the power consumption is larger, and the parking time is long and it is easy to lose power, due to the short driving distance every day, such as 20 minutes to and from work, it is easy to cause the charging to keep up with the consumption, especially in winter. Therefore, it is recommended to drive for a long time every day to restore the battery, or charge the car every once in a while, and the electronic charger is about 70-80 is not expensive. You can prepare one if necessary.

In addition, the following points should be paid attention to in the use and maintenance of car batteries, 1The starting time should not exceed 3-5 seconds, and the number of starts should not exceed 3-5 times. Each time there is an interval between them. Give the battery a break.

2.Do not stop for a long time to listen** or other electrical appliances, and listen to the car if necessary. Because the generator supplies power after the car.

3.If conditions permit, the battery is charged once every six months or a period of time, because there are certain limitations in driving charging, and charging a small current with a charger has a good effect on prolonging the service life of the battery.

As long as the above points are achieved, a battery can be used for more than 5 years, no problem.

Taking 12V60AH as an example, charging method: using constant voltage current limiting mode for charging, constant voltage current limiting 15A charging for 16 hours, and then charging with 3A constant current for 4 hours, a total of 20 hours.

If the battery is fully charged, it can be judged according to the following phenomena, or observe that the electric eye is green, that is, it is fully charged

1) A large number of bubbles are generated in the battery, which causes the phenomenon of "boiling";

2) The terminal voltage rises to the maximum value and does not rise again within two hours;

3) The electrolyte rises to the highest level and does not rise again within two hours.

Hello, if you are idling or driving in the city, it will take at least 30 minutes, and it is best to turn off all the electrical appliances, but if you want to say that it is full, then at least 2 hours.

The role of the car battery is to give the car a backup power to start, and the battery has been charged after 20 kilometers, which is completely enough for the electric energy you use for the next start, and it does not necessarily have to be fully charged, so you don't need to worry. As long as the car engine is in the ** motor, the battery will be charged in minutes, and you don't have to worry about whether the battery is full for a year, but if the battery is used for more than three years, the storage capacity will slowly decline, and it is time to replace the battery when it is completely insufficient.

How long does it take for the car to fully charge the battery?

If the battery is in good condition, the battery can be fully charged after about 20 minutes of driving after starting.

It is best measured in terms of the corresponding speed and time. After lap starting, it can be used for starting once in 20 minutes at 1500 rpm, and once in 30 minutes at 1500 rpm. The car battery fault light is on, and it can be charged at 1500 rpm for more than 60 minutes, and then charged at more than 1900 rpm for more than 60 minutes.

The battery is an important part of the car, when the engine is not started, the battery supplies power to the electrical equipment of the whole car, and the battery is also responsible for starting the engine.

After starting the engine, it is the generator that supplies power to the electrical equipment of the whole car, and the generator will also charge the battery. The battery is a wearing part that needs to be replaced regularly, and the battery storage capacity will be reduced after a long period of use, which will affect the normal use of the car.

Maintenance of car batteries:

1. Don't start the vehicle frequently, you will encounter the problem that the car is difficult to start in winter, and it is difficult to start, so it will start frequently. But the best way to do this is to start the engine for no more than 3 seconds at a time.

If the first boot fails, don't rush to boot it repeatedly. From the perspective of the working principle of the car, the continuous start of the motor at this time will definitely cause the battery to be over-discharged and damaged. The time interval between re-activations should be more than 5 seconds.

2. Predict the precursor of battery "strike", some batteries will become very strong after the internal resistance is used, and there will be a phenomenon that it will be full and finished as soon as it is discharged. When the owner has a battery life cycle of about two and a half years, the battery should be tested for routine maintenance, which can play a preventive role. Forgetting to turn off the lights in the car when parking and turning off the ignition is a small mistake that many new car owners tend to make.

3. After the battery is consumed overnight, it may run out of power at any time and cannot start the car. In this case, you can try to charge the battery if possible. If that doesn't work, the battery may need to be replaced.

Try not to use CDs, cigarette lighters and other electrical equipment when the vehicle is not started, and reduce the use of various on-board electrical appliances in the process of eliminating vehicles.

4. Turn off the air conditioner before turning off the engineMost car owners are used to not turning off the air conditioner or letting the air conditioner start automatically with the vehicle after starting, which will cause the air conditioning system to automatically start working after opening the ignition switch of the vehicle every time, the consequence is to directly lead to the instantaneous power load of the vehicle is too high, and the battery will be lost for a long time.

<> "Car batteries can be fully charged in a few hours.

How long it takes for the battery to be fully charged is affected by many objective factors. For example, the type of the battery, the degree of power loss of the battery, the charging current of the charger, etc. So how many hours does a car battery generally take to fully charge?

To charge the car battery, it generally takes 2 to 4 hours to be fully charged with professional charging equipment, and it takes 8 to 10 hours to be fully charged if it is charged normally with an ordinary charger.

How to maintain a car battery?

Before the vehicle is turned off, the owner needs to turn off the light switch and audio switch of the vehicle first, and then turn off the vehicle, so as to avoid the vehicle after the vehicle is turned off, the vehicle battery is still in a discharged state.

In the summer, car friends will use the vehicle's air conditioning function to reduce the temperature in the vehicle room, the owner must not use the vehicle, to first turn off the vehicle's air conditioning, dust cover and then turn off the vehicle.

When the owner uses the vehicle daily, he needs to regularly scrub the outside of the vehicle battery to keep the outside of the vehicle battery clean and clean. When scrubbing the outside of the battery, clean the positive and negative battery columns of the vehicle by the way, keep the vehicle battery column tidy, and apply special grease on the vehicle battery column to protect the vehicle battery and prolong the service life of the vehicle battery.

The above is all about the car battery that can be fully charged in a few hours.

Under normal circumstances, the new battery should be flushed for 24 hours.

Car batteries. The normal life expectancy is generally about two years. With proper maintenance, it can be extended, and the best can be used for more than 4 years.

A note to you:

1. When starting the car, the starting time should not exceed 3 to 5 seconds each time, and the interval between starting again should not be less than 10 seconds.

2. The car is often driven for short distances, which will cause the battery to be in a state of insufficient charging for a long time and shorten the service life. Driving on the highway at a steady speed for 20-30 minutes can give the battery a full time to recharge.

3. When driving daily, check and make sure that all lights and other electrical appliances (such as radios, CDs) have been turned off before leaving the car. Because this may drain your battery.

4. If the battery is depleted, it is required.

Borrow fire. (jump-starting, also known as hitching) to start, should immediately try to drive at a constant speed (such as highway speed) for at least 20 to 30 minutes, and fully charge the battery.

5. In the case of complete battery discharge, borrowing fire may not be able to help you start the car. At this time, you need to use a specialized.

Battery charger.

Slow charging.

6. If the car is not used for a long time, the car should be fully charged first.

1. Under normal circumstances, the trolley engine can be charged for more than 60 minutes at more than 1500 rpm, and then charged at more than 1900 rpm for more than 60 minutes.

Accumulator. Basically full.

2. The battery power is less than half, that is, when the voltage is lower, it is difficult for the car to start, and the battery.

Warning lights. Lights up.

3. The car is driving on the highway, and it is basically not driven with high power.

In the case of electrical appliances, such as air conditioners, headlights, etc., the battery is basically fully charged after 2 hours.

4. In actual use, it is impossible for the battery to be truly full, for the following reasons:

a. Battery required. There is a so-called.

Trickle. "Charging, in order to enrich the battery, that is, full, b, the trolley generator in order to meet the operation of the on-board equipment, the output of a maximum current, far more than the best charging current of the battery, this current can not enrich the battery, c, the trolley driving process, the power consumption is uneven, the battery may always have current in and out.
