What s wrong with my electric car s battery????????

Tell you clearly, the battery is hanging, the reason is that the limit has arrived, or one of the batteries has arrived, honestly change the battery, remember not to buy miscellaneous batteries, afraid of refurbished batteries I, you can learn from it.

Open the battery box: look at the date number on the battery (generally there are two kinds of coding and coding), for example: 20140221** or ***140221*** Regardless of the specific number, it contains the production date number, as in the previous example, it was produced on February 21 this year.

If it's an old battery refurbished, then the date won't run away unless it's erased or scratched off, and if you can't see the date on the battery, then be careful!

In addition, if it is an old battery, then there will be some scratches on the shell and the handwriting of the battery model manufacturer is not clear!

If you go to a special dealership of a big brand, you will not be fake!

A production date of less than 1 month is generally normal, because it takes time to ship and sell.

20V DC gear with a multimeter. Check the voltage of each battery one by one. For example, display . Indicates cell balancing. The state stipulates that the error is a regular product, and the best can be achieved within it.

Replace the battery, it is not refurbished, it is all new.

You can't just change the battery.

If you have to turn on the electricity for a few minutes before you can catch fire, the possible reasons are as follows:

1. Idle electric shock.

2. The engine is aging and the cylinder pressure is insufficient.

3. Fuel single valve.

4. The pressure of the gasoline pump is insufficient, and the gasoline filter element.

5. Circuit failure.

It usually takes about half a minute to start the hot train in the morning. The main reason is that there is a process of preheating electrical equipment, so that the self-test of each sensor is over, and then the ignition will be smoother. Studies have shown that more than 90% of the wear and tear of engine parts is caused within three minutes after the cold engine starts.

Therefore, it is necessary to turn on the power supply for a few seconds to perform a computer self-test, and then ignite and warm up for half a minute before driving.

What should I do if the electric car battery is out of power? This one is very simple, just charge it with a matching charger.

What to do if the electric car battery is out of power If the car makes a clicking sound when ignition, but it just can't ignite, it means that the car still has residual power. When there is residual power, the cart can be started, but this is a last resort and cannot be used often, because this will cause certain damage to the engine and clutch, and automatic transmission vehicles should especially avoid using this method to start. If the car battery is dead, you can do it according to the following methods:

1. If the lights can still be turned on, the manual transmission car can be started by starting the trolley, you can hang up the 2nd or 3rd gear, step on the clutch, and then push the car, when the speed reaches a certain release, the vehicle can be started; 2. If there is no power at all and you want to have an emergency, you can connect the battery wire to someone else's battery and borrow someone else's battery to start; 3. In order to avoid the battery being unable to charge normally when the battery is empty, the owner should prepare a jumper cable in the car, however, when connecting the jumper cable, you must not mistake the connection sequence of the jumper cable. 2019

1. Start the trolley

Trolley start is the most familiar and effective emergency starting method, but this is a last resort and can not be used often, because there is a certain amount of damage to the engine and clutch, and automatic transmission vehicles should especially avoid using this method to start.

2. The most reliable:

Contact the ambulance. The most reliable way is to contact the rescue vehicle in time, and then connect the jumper cable and temporarily charge the rescue vehicle to start the engine.

3. Spare cable charging:

In order to avoid the battery not being able to be charged when it is empty, the owner should prepare a jumper cable in the car, which can be bought in the general auto parts store. However, when connecting jumper cables, it is important not to misconnect the jumper cables in the order in which they are connected. It is necessary to first connect the positive terminal of the dead battery with the positive leakage terminal of the rescue vehicle battery, and then connect the negative terminal of the rescue vehicle battery with the metal part in the engine compartment of the dead car.

1. Start the trolley. This is one of the most common methods. If the electric car runs out of power while driving, we can start the vehicle by pushing it.

2. Slip the pedal to generate electricity. Many electric vehicles have similar features. When an electric car has no electricity, pedals can be used to generate electricity. When riding an electric car, foot power generation is better than pushing a trolley.

3. Seekers can quickly find nearby electric vehicle charging stations. Now electric car repair shops have a place for fast charging. Even if an EV driver doesn't have a charger for their EV, don't worry.

The charger of the charging station can be used directly. Generally speaking, the charging time is not too long.

4. Call ** for corresponding help. If a person is in a remote place and there are no charging stations around, they can call for help, or contact the rescue vehicle and charge the electric vehicle in time. Of course, it is best to regularly check the power of the electric vehicle.

If the electric vehicle is insufficient, the electric vehicle should be replenished in time.

5. Some electric vehicles have added a special red button, the red button is marked as normal and is the manufacturer in order to solve the electric vehicle in the middle of the road, specially designed emergency power supply button, press it, you can put the battery under normal circumstances will not put the residual power, completely release, so as to achieve the purpose of electric vehicles riding home, at present, most of the two-wheeled electric vehicles and a small number of electric tricycles are equipped with such intelligent functions, you can see if your electric car has, use it to respond to emergencies when critical.

6. Use auxiliary tools to assist in emergency response, use electric vehicle booster to drive, which is more suitable for two-wheeled electric vehicles, but when the vehicle is out of power, it is very laborious to implement, and such a tool can realize the easy implementation of the vehicle, especially in the event of a vehicle puncture, it can replace the wheels and ride home directly, which is a good backup tool.

7. Use the emergency power supply, the mobile phone goes out to carry the power bank, in order to prevent the lack of power, then, now there is also a power bank for electric vehicles, this way, electric vehicles, electric three-wheeled can be used, when there is no electricity, add a certain amount of power, so that the vehicle can ride home smoothly.

After a few days of full charge, there is no one possibility that the battery is seriously self-discharged, and the other possibility is that the car itself leaks. You can remove the battery from the car after it is fully charged, if it still runs out of power after a few days, it is a problem with the battery, and if there is power, you need to check the wiring of the vehicle.

Maintenance Method:

1. The battery cannot be charged at any time.

1. The lead-acid battery is not a lithium battery, it can not be charged at any time, the life of the lead-acid battery is calculated according to the number of flushing and discharging, the battery is most afraid of power loss, and often keeping enough power can extend the life of the battery.

2. When charging, the indicator light of the charger is first red and then green, and the front of the bucket is wide, and the floating charge should be guaranteed for 2 hours after the light turns green, which is good for inhibiting battery vulcanization.

2. Prevent the battery from being overcharged.

1. The overcharging of the battery produces a large amount of gas to wash the plate, which accelerates the shedding of the active material on the plate and shortens the life of the battery.

2. The overcharging of the battery accelerates water loss, resulting in the drying up of the electrolyte and the increase of the battery temperature, resulting in thermal runaway, plate expansion and shell deformation.

3. Prevent over-discharge of the battery.

Pay attention to skills in the use of battery cars, and also prolong the service life of the battery. Long-term deep amplitude discharge will cause the battery plate to soften and shorten the service life.

1. Prevent high-current discharge, and try to help with your feet when starting, uphill and headwind.

2. Prevent long-term discharge, and do not drive after discharging frequently. Charge when the charge level is 1 2 low.

Fourth, prevent the battery from losing power.

For batteries that have been left unused for a long time, they should be fully charged once a month, and it is generally better to continue to float for 5 hours after the charger turns red to green.

5. Take care of the battery frequently.

Although the electric vehicle battery is maintenance-free, after half a year of use, with the continuous consumption of water, the vulcanization and softening of the plates will occur, which will cause the battery capacity to decrease or even fail. Choosing to supplement the nano carbosol battery activator and the appropriate amount of distilled water (don't do too much) can extend the battery life to more than two years.

Summary. Hello dear, the battery is the energy of electric vehicles**, most of today's electric vehicles are equipped with lead-acid batteries (low cost, high cost performance). This type of battery can be recharged and can be used many times, so it is called "lead-acid battery battery".

Lead-acid batteries will be vulcanized in the whole process of use, and the environment of electric vehicle lead-acid batteries also causes lead-acid batteries to be more easily vulcanized. What happens when an electric car suddenly runs out of power? There are five reasons why the electric vehicle suddenly has no electricity, one is the problem of the electric vehicle's route, the second is that the battery is broken (there is a virtual electricity so that the light can flash), the third is that the brake pedal is not in place, the fourth is the control board is leaked and burned, and the fifth is the common fault of the turn handle is invalid.

If the whole car is out of power, it is possible that the motor flow is too large to cause power tripping, and then the power supply system can also be repaired according to the disconnector under the opening base.

What happens when an electric car suddenly runs out of power? There are five reasons why the electric vehicle suddenly has no electricity, one is the problem of the electric vehicle's route, the second is that the battery is broken (there is a virtual electricity so that the light can flash), the third is that the brake pedal is not returned, the fourth is to dismantle the control plate and seep into the water and burn it, and the fifth is that the common fault of the handle is invalid. If the whole car is out of power, it is possible that the motor flow is too large to cause power jumping, and then the power supply system can also be repaired according to the opening of the bend under the base.

The whole vehicle suddenly has no electricity, and there is no problem in checking the air leakage switch mold and fuse wire, at this time, you should look at the battery Lu Shikai line home or the battery socket is broken, or the gear return is a problem of poor contact. Generally, it can be used to drive the transmission line or unplug and unplug it and fix it again, and check it one by one.

If there is a shortage of battery water, adding some will be the same as a new battery.

Electric vehicles, i.e., electrically driven vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. It is generally said that electric vehicles are vehicles that use batteries as energy**, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the current and change the speed.

The first electric car was built in 1881 by French engineer Gustave Truf, a three-wheeled vehicle powered by a lead-acid battery, which was powered by a DC motor.

The battery is a type of battery, also called a battery, which works by converting chemical energy into electrical energy. Usually the battery refers to the lead-acid battery, that is, a battery that is mainly made of lead and its oxide as the electrode, and sulfuric acid solution as the electrolyte.

What should I do if the car battery is out of power? Remember this method and you can do it yourself!

When the battery is at the end of its life and has passed the shelf life, it can be considered to repair it, but the repair is very limited, it cannot be compared with the new battery, and the repaired battery can only last for 3 to 6 months. Restoring electric vehicle batteries is a very professional profession, which requires a mastery of the internal oak composition of the battery and the principle of the battery. Not all batteries are worth refurbishing, generally if you can use refill or recharge cycles to extend the battery life, you can repair it, and others like no voltage and no current are not necessary.

When the appearance of the battery is not damaged, swollen, and there are no signs of short circuit or open circuit, the following methods can be taken to try to repair the battery:

1. Use positive and negative pulses to depolarize the battery, and then completely discharge, so that three cycles, if the capacity has signs of recovery, you can cycle several more times to achieve better repair effect.

2. Add water for repair, add deionized water or pure water to add water, do not add tap water, it will cause a large problem of battery self-discharge. Here's how:

1) Discharge the battery completely first (after discharge, the acid density inside the battery is basically the following, which is close to the nucleus of the aqueous limb);

2) Take out the cover piece, and then remove the safety valve, pay attention to keep it, do not dirty the safety valve, for later use;

3) Add water, generally the water added in a single grid of 12Ah battery is 8 10g, and the water added in a single grid of 20Ah battery is about 15g;

4) Let stand for about an hour, and install the safety valve and cover sheet;

5) Use the matching charger for charging, and then fully discharge after being fully charged, and so on for three cycles.

That is true. The battery is broken.

Go to the after-sales service immediately to change it, and you will be distracted.

One-year warranty. I won't pay attention to you if I lose money when it expires.
