How to save yourself if the car battery fails suddenly, and can you still start it with electricity

<> people who have electric cars do not necessarily have cars, however, people with cars basically have electric cars, the probability of sudden power failure of the car is very small, it basically has a process, that is, one, two, within the year, there will be no sudden power failure, but after three or five years of the car, the performance of the battery will slowly decline, plus everyone's car habits are different, so usually, the service life of the battery is two to five years, and it is rare to use it for six or seven years, so if your car has been used for more than three years, you must pay attention to the working status of the battery at any time, just mentioned electric vehicles, if you have the conditions, prepare a 12 12A electric vehicle battery, do a good job of 4 squares, (the wire is thin and does not catch fire), a long meter of connecting wire. Two, at least 4 yuan to buy 2 medium-sized crocodile clips, welded for backup, and the following displacement of the car can be played, you can also buy a 12V car charger, ** in 80-300 or so, but this requires you to have a long enough power cord with the car, and, buy a live wire to put on the car for backup, this is the most convenient, remember to recognize the positive pole and negative pole when the tower line. Five to ten minutes to start is fine.

I've come across a case where a car gradually stalls while driving:

My friend's car gradually extinguished the fire while driving in the town, and only a slight motor relay was heard when it was restarted, the motor did not run, and when the motor was not taken (the key door was in the ON position), the indicators on the dashboard were displayed normally, and the above symptoms appeared in the starting position and the indicator lights were off;

After inspection and measurement, the voltage of the battery pole is normal, and the battery pole card looks very clean, and there seems to be nothing abnormal, giving people a feeling that the battery power supply is normal. However, when the motor is started, the voltage of the positive and negative poles of the battery line is as low as a few volts! The battery voltage is still normal, which shows that there is a great resistance between the battery pole and the battery line card!

Remove the Jizhuang test and find that there is an oxide film in the positive line card, wipe it with sandpaper until it is bright and press it again, and everything is normal when the fault is eliminated and started! Troubleshooting.

On the surface, all normal material phenomena are not necessarily the actual situation, so we must be calm when encountering faults, and deal with them at the source, which will have twice the result with half the effort.

There is no such thing as a sudden power outage in the car, is it not on fire? The whole car is out of power? None of the meters and lights are responding? Let's explain them one by one.

1.It doesn't catch fire, but the gauges and lights are all normal!

In this case, the problem lies in the starting system, the fuse is burned, or the life of the starter is up, and the battery head is loose, the contact is not good, and the ignition switch contact is poor!

2.The whole car is out of power?

This odds can really go to buy lottery tickets, generally the battery head oxidizes and the total insurance burns!

When encountering two kinds of problems, first find out the root of the problem, otherwise how you can connect the external power supply is useless, when it comes to the external power supply a little common sense people understand, one positive and one negative, according to the color of the dragon over the river!

If the car battery suddenly fails, we immediately pull over and turn on the warning lights. But at this time, don't blindly start by yourself, and call the police** for help.

If the car battery fails, you need to find another car and use its battery to activate your car's battery.

It can be started by electric power. You can ask your insurance company for road assistance, free if it's not in the middle of nowhere, or ask a friend for help, or if you're not working, you can find a car repair shop.

You can start the car by yourself with an external power source. At this time, it can be started with electricity, and there is no effect on the engine and battery.

If the cause of the battery failure is found out and eliminated within the approximate service life of the battery, the battery is generally still usable.

The car battery is out of power, and how long it can be used after charging depends on the actual situation of the battery.

1. If the car battery is out of power, it only occurs occasionally.

One or two times, which does not happen often, generally does not affect the service life of the battery.

2. However, if the battery is often out of power (the battery is over-discharged), for example, the car is often not opened for ten days and half a month, and the auxiliary electrical appliances installed in the car are often turned on, such as navigators, immobilizers, radios, etc., resulting in the battery has been in a state of discharge.

3. Another point is related to the principle that the battery can store electricity, the battery is a pure chemical reaction inside, which converts electrical energy into chemical energy storage, because the chemical substances are related to the battery structure, temperature, specific gravity, impurities, etc., and self-discharge will occur.

4. This self-discharge will generally be discharged within a day. When the battery is in a long-term self-discharge state, the car has been consuming electricity with useful electrical equipment, the car does not open the battery to supplement the battery, and the battery adopts a poor liquid design, the water in the electrolyte will gradually volatilize, and will gradually form white lead sulfate.

Tips for bottle maintenance:

1. Scrub the outside of the battery with a damp cloth, and wipe the dust, oil, white powder and other dirt that is easy to cause leakage on the panel and on the pile head (that is, the positive and negative poles). In this way, the battery will be scrubbed frequently, and the pile head of the battery will not accumulate white etching powder, and its service life will be relatively long.

2. Open the battery and water cap to see if the water level is in the normal position. Generally, there will be upper and lower limit markings on the side of the battery for your reference. If you find that the water level is lower than the lower mark, you must add distilled water, if you can't get distilled water at once, you can use filtered tap water to deal with emergencies.

Don't add too much water, the standard is to add it to the middle of the upper and lower reticles.

4. If there is no three-power meter, you can use the visual inspection method: after the engine starts, open the battery and water cover to see if there are bubbles in each small compartment. The normal condition is that bubbles are constantly coming out of the water, and the more oil you add, the more they will rise; If you notice that there is no bubbling, it is likely that there is something wrong with the charging system.

Electricity is a very common practice. After the battery is built, the car can quickly fully charge the battery by relying on its own power. So if the car can start normally, it means that there is no problem with the battery.

If there is a problem elsewhere, it is not caused by electricity. If you don't worry, you can go to the repair shop and let the master check it.

You'd better go to a professional repair department to check the cause of the lack of power, determine whether the battery has hidden dangers, and whether the battery needs to be replaced.

You'd better go to a professional repair department to check the cause of the power outage, and finally determine whether to replace the battery.

It's okay, your battery isn't broken, it's just that you accidentally leaked it.

There may be two reasons for the battery to be dead, one is that the life of the battery is expiring or there is a problem, and the other is that the headlights are forgotten to turn off and the other is a loss of power. It can be started by one of the following three methods: 1. It is towed and dragged by other vehicles; 2. Borrow the power supply of other vehicles to start; 3. Use downhill to start.

The method of using the battery to connect the wire, borrowing the power supply of other vehicles to charge, the specific method is: prepare two relatively thick wires, if it is purchased in the market, it is generally divided into red and black. One end of the red wire can be connected to the positive pole of the tram battery, and the other end can be connected to the positive pole of the tram battery.

One end of the black wire is connected to the negative pole of the battery of the tram, and the other end is connected to the metal part of the tram. A tram starts first to drive the tram to land. Here we also want to emphasize that the power supply car should be in a running state, first lapping the positive electrode, and then lapping the negative electrode; After starting, first loosen the negative electrode, and then loosen the positive electrode.

This can prevent the negative pole from accidentally touching the positive pole with the car body halfway after connecting the negative electrode first, resulting in a short circuit. "

Hello The first thing to say is that if you find that the vehicle can't ignite when you usually use the car, at this time, regardless of whether the vehicle starter can work or not, as long as the vehicle can't hit many times, don't continue to try to ignite.

The reason why we can't try to ignite for a long time is because first of all, we assume that the starter can work normally, but the vehicle can not start normally, then it means that there is a problem with other components such as the engine, if you continue to try to ignite at this time, it is easy to use up the electricity in the battery, and at the same time, continuous ignition is also not good for the starter, and secondly, if you find that the starter can not work normally when ignition, then it is likely that the battery has lost power at this time. It will cause damage to the vehicle's battery, or even lead to the battery being scrapped.

If it is confirmed that the vehicle is a battery loss, you need to find other vehicles to take the rescue, and the front of the rescue vehicle should be as close as possible to the front of the rescued vehicle, so as not to be too far away and the length of the wire is not enough.

At this time, it is best to turn off the power of the rescue vehicle, so as not to cause a short circuit in the vehicle circuit due to negligence and reverse the positive and negative poles of the battery, and cause damage to the electronic equipment of the vehicle.

First of all, you need to measure the starting voltage of the battery, not less than 10V battery, no problem. After taking the battery, measure the voltage of the battery pole to determine whether the generator is charged. If it's all right, check whether the motor is swept or not, if the gap is too large, the battery power is slightly insufficient, and the motor is not enough to start.

Hello, you can go to the place where the car is repaired to check the battery, and the generator, the battery problem is more, it is recommended that you check the battery to see.

There are reasons for the battery and the engine that can't catch fire.

If you can still turn on the lights and sound the horn, but the starting motor is weak, the manual transmission car can be started by starting the trolley, you can hang up the 2nd gear or 3rd gear, step on the clutch, push the car, when the speed reaches a certain release, the vehicle can start.

If there is no power at all, you can use the battery wire to connect to someone else's battery to borrow someone else's battery to start. But it is best to take off the battery and send it to the battery shop for charging, because the battery is completely out of power, and it cannot be fully charged by the vehicle for a short time, and the capacity can only be restored through a long period of charging.

If you have a portable charger, you can charge it directly in the car without disassembling the battery. If the car drives less, it is better to buy one yourself, ** is very cheap, dozens of yuan a piece, you must buy the kind of switching power supply, can be full of self-stop smart charger.

1. The manual gear can be pushed and started, 2. The battery is lapped to start, and 3. The battery is charged to the top and starts.

Related knowledge: 1. After starting, charging at 1500 rpm, after 20 minutes, it can be used to start once, and after 30 minutes, it can be used to start once the next day, 2. Measure the battery voltage with a multimeter, the general voltage is lower, the car is difficult to start, and the battery will lose power if it is lower than the battery, 3. The battery is drummed, and it can be judged by visual inspection, at this time, the battery voltage may be higher, but the power is less, and it is possible not enough to start, 4. The battery is aging, and the capacity decreases more, which is manifested in: a charge is full, and a use is not. The no-load voltage is normal, and the voltage drops below 10V when starting.

Summary. Hello, this situation has nothing to do with the battery, it is a problem with the generator, and it still can't be started after an hour and a half of starting, indicating that the generator is faulty and the battery is not charged enough. Repair this problem to check whether the small plug behind the generator is loose and the line is broken, the generator excitation is normal, but it cannot generate electricity, the belt does not slip, the generator is damaged, and the generator can be replaced.

There is a time limit for the first reply, if you have any questions, you can reply and answer them in detail.

After the car loses power, it takes the power and starts for 1 and a half hours, and then it still can't be automatically ignited, is it a problem with the battery? This battery is a new one that has just been replaced.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

You need to have a battery connection cable first, one end is connected to the positive and negative poles of the other car to the positive and negative poles of the battery and the other end is connected to the positive and negative poles of your vehicle, the positive pole is to the positive pole, and the negative pole is to the negative pole.

There are positive and negative poles written on the battery, generally the red "+" sign is the positive pole, and there are generally two wires, at this time, take out the red one first, open the battery cover, pinch the clamp on the head to clamp the positive pole of the non-tram battery, and the other end of the clip clamp firmly the positive pole of the rescue car battery. Be sure to connect the positive electrode first, then the negative electrode, do not reverse the order, and do not use the battery clamp to touch anywhere except the battery pile head.
