If the car doesn t drive for a week, how long does it take to fully charge the battery?

5-8 minutes, in general, the rated capacity of the on-board battery on the car.

It's about 60ah, the longer the car is parked, the more power the battery releases, if we discharge with a current of 60a, then it can last for a time to discharge.

Although some cars are parked, there is also a dash cam installed on the car.

This also requires electricity consumption, so if the car releases electricity per hour, then a week is. Coupled with the large amount of current consumed by the body when starting, it is roughly calculated that if the vehicle is not driven for a week, it will take 5-8 minutes to charge it back.

I don't open for a week, it doesn't matter, my car often doesn't drive for half a month or even a month, it is normal to fire, normal to drive, there is no problem, the kind of battery negative electrode that is not turned on for a few days, it is a blind command. Now the car is EFI, the throttle opening and so on are all memorized, after disconnecting the battery, all kinds of memories will disappear, rematching, the next time you drive will definitely be particularly awkward, it will take a certain amount of time to return to the normal level. At this time, it is often necessary to stop again, and then disconnect the battery, so that the daughter-in-law tosses back and forth, and the good car is also scrapped.

Just open it normally, don't care about these, the current driving computer has voltage detection, and the power supply of some non-essential equipment will be turned off after the voltage is low, and it will not be completely exhausted. If it takes a long time, the car will not start. Find a battery or a car with electricity, and the car will start on its own in ten minutes.

I drove out and ran dozens of kilometers and rushed up.

Some time ago, our family's car was left unattended for a week. I have more say in this, the car is not open for a week, and the power loss is not large. Generally, the dark current of a car is between 10-30mA, so the power consumption in a week is about:

24h×。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.

I am specialized in the car repair business, I think for those users who have a single vehicle running time of less than 30 minutes (especially less than 15 minutes), such a vehicle operation state will make the battery in a state of dissatisfaction for a long time, which will greatly reduce the service life of the battery. Try to keep the vehicle running for more than 30 minutes in half to a month, not only for the battery, but also for the engine. For those vehicles that are not in use for a long time, it is possible to have two months to get the vehicle fully running (not 1 hour), which is good for the engine, transmission, battery, tires and other parts of the vehicle that are responsible for turning.

Then the time it takes to charge the battery with ampere current is hours, about 35 minutes. Since the charging current will decrease when the battery is almost full, 35 minutes is only a theoretical data, and it actually takes longer, but it will basically not exceed an hour. So as long as your car's dark current is normal, basically the power consumed by parking for a week will be replenished almost an hour after the engine starts.

Even an hour of idle is no problem, because the generator is fully capable of charging the battery at idle.

As long as the car battery has about half of the electricity, can start normally, the car battery put a week, can start smoothly, if put on about 20 days, it is not easy to say, after the normal full, the battery voltage is about volts. The battery is mainly afraid of power loss, usually do not use the car for a long time, need to disconnect the negative pole of the battery, to avoid the static current consumption of some on-board electrical appliances, or every half a month, on the car, run for more than 5 minutes, to replenish the battery.

The car is parked for a week and does not drive, as long as you start the car again, it is fully charged instantly, because the power loss is negligible. When I first learned my driver's license, I spent 10,000 yuan to buy a seven-year-old Geely King Kong, which was not driven to work, but was placed in my rural hometown, and I went back to open it every Chinese New Year.

It depends on your battery capacity, if you are a regular battery, it will take about 30 minutes, if it is a vehicle with a start-stop function, it will take about an hour.

If your car is bought for a short period of time, it is no problem to put it for a week or half a month, if you put it for about a month, you should start the car and charge the battery for 20 minutes, and if the storage time is still long, the charging time should be extended, so that you can extend the service life of the battery.

It is very harmful for a car not to be driven for a long time. So what should be done about this situation? Warm up every other week and run for about 15 minutes.

Ensure the lubrication of moving parts and the formation of protective oil film, which is good for the engine and moving parts, and at the same time, it can also properly replenish the battery. Check the battery every other month to see if there are any signs of power loss. If there are signs of power loss, the engine can be used to properly charge the battery.

The car battery is out of power, and the car battery can basically be fully charged after running at high speed for more than an hourSuch a battery can be kept in the best condition, some batteries will become very large after the old internal resistance, there will be a full charge, a phenomenon of finishing, the battery life cycle of about two and a half years, routine maintenance should detect the battery, which can play a preventive role.

Precautions for daily use of the battery:

1. Turn off all lights before turning off the fire.

Some older models do not support the function of automatic power off after the ignition is turned off, so you need to manually turn off the lights and the reading lights in the car before turning off the ignition. If you need to find something in the car or need lighting, you can use a mobile phone or flashlight to illuminate, so as to avoid forgetting to turn off the reading light and causing battery power loss.

2. Turn off the air conditioner and stereo before turning off the fire.

The air-conditioning system involves compressors, blowers, and audio is also high-power electrical equipment, which is not turned off before the engine is turned off, and will automatically start when the next time you land on the car, which will cause a heavy burden on the battery and cause damage to the battery. In particular, some ** audiophiles have modified the audio of the car, and the usual power consumption increases, and the impact on the battery will be greater when starting, so whether it is temporary parking or long-term parking, the air conditioner and audio must be turned off before turning off the engine.

Taking a 12 volt 60 mAh battery as an example, it is charged by constant voltage current limiting, charging at 15A for 16 hours, and then charging for 4 hours with 3A constant current, and it takes a total of 20 hours to be fully charged. Knowing that the battery is out of power, it is best to remove it and fill it up and install it again, the service life of the battery will be longer, often lose power, do not charge in time, and directly drive to charge for a while and a half will be unsatisfied.

2. Very fast charging (constant current charging), many car owners think that fast charging can save time, as long as 3-5 hours; I don't think so, the fast charging only quickly activates the surface of the battery, but in fact, the inside of the battery is not fully charged;

3. Slow charging (constant voltage charging), there is a charging method for car batteries, for slow charging, the charging time is 10-15 hours, and some deep loss batteries must be charged slowly, otherwise the charging time is not enough, and the charging amount is insufficient, which will affect the driving performance of the car at the same time.

It usually takes half an hour. Connect the positive terminal of the battery to the positive pole of the power supply, and connect the negative pole of the battery to the negative pole of the power supply, which is carried out in two stages:

1. First charge the electrolyte with the initial charging current until the bubbles are released, and the single-cell voltage rises to the end. Then the current is reduced to 1 2 initial charging current, and the charge is continued until the electrolyte releases violent bubbles, and the specific and voltage are stable for 3 hours continuously.

2. The total charging time is about 45-65h. The temperature is controlled at 35-40, and when the initial charge is completed, if the specific gravity of the electrolyte does not meet the regulations, it should be adjusted with distilled water or the specific weight of the electrolyte. After adjustment, charge for another 2h until the specific gravity meets the specified level.

3. The new battery often cannot reach the capacity after the first charge, and the discharge cycle should be carried out. Discharge at the discharge rate at 20h (that is, discharge with the current of the rated capacity of 1 20 until the voltage drops to the single grid), and then supplement the charging current until it is sufficient, after a charge and discharge cycle, if the capacity is still less than 90% of the rated capacity, another charge and discharge cycle should be carried out.

There is no specific time for how long it can be fully charged, this depends on the size of your battery, new and old, engine speeds, etc., basically running a few hundred kilometers at high speed.

The car does not open for a long time: the battery is empty, and the battery can be charged to more than 80% of the power without extinguishing the car half an hour after the vehicle starts.

The disadvantages of not driving the car for a long time: 1The battery is dead. 2.Aging lines. 3.All kinds of originals are rusty. 4.Gasoline oil quality deteriorates, and so on.

It is recommended to turn on or idle for 10 minutes at least once a week, let the oil circuit be fully lubricated, and turn on the air conditioner, and the car will be back to life.

1. The car is parked for a week and does not open, only the mask is used to start the car again and be fully charged instantly, because the power loss is negligible.

2. Ordinary cars do not need to deliberately start charging in the winter when they are not in the alpine area, and they can start normally after parking for a few months, but the battery may have lost power, and the winter in the alpine area needs to run for about half an hour.

Generally runHigh speed for more than an hourThe car battery can basically be fully charged, and the battery can be kept in the best condition.

Some batteries will become very strong after being used, and there will be a phenomenon that they will be full as soon as they are charged and finished as soon as they are put away. 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.

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 use less various on-board electrical appliances during driving.

How long does it take for a car battery to be fully charged when it is out of power, take a 12-volt 60 mAh battery as an example, use a constant voltage current limiting method to do a good job of charging, constant voltage current limiting 15A charging for 16 hours, and charging at 3A constant current for 4 hours, it takes a total of 20 hours to be fully charged. Knowing that the battery is out of power, it is best to remove it and fill it up in installation, the battery life cycle will be longer, often lose power, do not charge immediately, and the car will be charged for a while and a half.

There is a generator next to the car engine, and the belt of the engine drives the generator to rotate, and then the generator is generating electricity to give electricity to other places in the car. At the same time, the battery is charged by generating electricity, and the battery will have a steady stream of electric energy.

Take a 12 volt 60 mAh battery as an example, charge it with constant voltage and current limiting, charge it for 15A for 16 hours, and charge it for 4 hours at 3A constant current, and it takes a total of 20 hours to fully charge. Knowing that the battery is out of power, it is best to remove it and fill it up in installation, the battery cycle will be longer, often lose power, do not charge immediately, and the car will be charged for a while and a half.

Can I charge at idle?

When the car is idling, the voltage of the generator (i.e., the potential difference) can meet the charging conditions, and the current is very low but most of them are sufficient, but the premise is that the high power of air conditioning, high beams, car stereos, and refrigerators cannot be used, otherwise it will exceed the maximum output power of the generator, but overdraft the battery, resulting in permanent damage to the battery.

Answer: Different brands of vehicles, the generator power is different, the battery capacity is different, that is, the same car, under different engine speeds, the time of full charge is also inconsistent. Under normal circumstances, the car engine needs to maintain a speed of more than 2000 rpm, and the car needs at least 4 hours to fully charge. The generator on the car needs to be at speeds above 2,000 rpm to run at full capacity, when the power generation reaches the nominal value on the nameplate.

If the engine speed does not reach 2000 rpm, it will take longer to fully charge. If the battery power of the car is too low, the car will not be able to start, and it needs to be powered to start, and the positive pole of the battery of the electric vehicle will be connected to the positive pole of the battery of the depleted vehicle, and the negative pole will be connected to the negative pole, and it can be started.
