What is the reason for the fast consumption of lithium batteries in battery cars?

The reasons why the battery car consumes power too fast are:

1. The battery is used for a long time and is caused by the aging of the plates;

2. If the motor is old, the carbon brush is seriously damaged, and the bearing lubrication is not good, it will also cause the battery car to consume power quickly;

3. The power storage capacity of the battery decreases due to the decrease in temperature;

4. The battery car has a short circuit and so on.

Electric vehicle battery routine maintenance:1. Be sure to check the small round hole in the battery cover for ventilation when driving.

If the small round hole in the battery cover is blocked, the hydrogen and oxygen produced cannot be discharged, and when the electrolyte expands, the battery case will crack, affecting the battery life. 2. Check the positive and negative electrodes of the battery for signs of oxidation. You can often pour hot water on the wiring of the battery, wash it with a copper wire brush, and apply butter.

3.Check each part of the circuit for aging or short-circuit fault locations. Avoid premature battery scrap due to over-discharge.

4.The battery is dead and can't be put down. If the battery is left for a few days after use and then recharged, the plates are prone to sulfation and the capacity will decrease.

5.Periodic Inspection: Measure the voltage of the single battery regularly.

If the voltage of one battery is lower than volts, please go to a repair center to check or repair it to avoid damaging the other two intact batteries.

Daily travel is inseparable from electric vehicles, and electric vehicles will encounter various problems in the process of use. Recently, some car owners have responded that the electric car has been riding for two or three years, why can't it run far after changing the new battery, what is the reason?

In fact, after a period of use, electric vehicles often encounter some problems, some of these problems are easy to be found by the owner, some of them need to be troubled, such as shortening the battery life, after replacing the new battery, or not far, this category belongs to the problem that makes many car owners difficult, then we need to self-check the electric vehicle to find out the reason.

Vehicle self-inspection to find out the cause.

After replacing the battery, there are two main reasons why the electric vehicle cannot run far: 1. Controller problem; 2. Rear hub problem.

The first thing you need to do is to see if the controller is malfunctioning. If there is a problem, it means that a resistance is generated in the process of converting the current, which causes the current to be lost, resulting in the electric vehicle battery.

The battery life drops sharply, and the new battery of the electric vehicle cannot run far.

1. It is relatively simple to judge whether there is a problem with the controller, and from the analysis of the riding state, the main manifestations are:

1) The driving speed of the electric vehicle is relatively slow, the acceleration process is slow, and the power is obviously insufficient;

2) The electric vehicle starts to tremble, which is generally due to the lack of phase of the controller;

3) The electric vehicle starts noisy, the load speed slows down, and the car cannot start zero after stopping.

When there is a problem with the electric vehicle, it can be preliminarily judged to be a controller problem, but it also needs to be comprehensively reacted to, and the specific methods are as follows:

2. To judge whether it is a motor problem, first prop up the rear wheels of the electric vehicle and let the rear wheels be in a suspended state

1) Rotate the rear wheel by hand, the rear wheel rotates normally, but the acceleration is one by one, indicating that the motor is fine, it may be a problem with the control line.

2) If the rear wheel rotates abnormally, check whether the brake is too tight, and the brake too tight will also lead to an increase in rotational resistance.

3) Turn the rear wheel by hand, the rear wheel does not rotate, and it will ring, it may be that the motor bearing is broken, or the internal brake pads.

Broken, stuck in the hub.

4) There is also a situation that the motor hall is broken, and the motor will not rotate, unable to run or abnormal noise, resulting in the phenomenon of open circuit, that is, after stopping, you can't go.

Solution: How to solve the above problems?

In fact, you don't have to think about it, just go directly to the car repair master, because only the brakes are too tight and we can solve these problems by ourselves.

The reason why you want to understand the problem of electric vehicles yourself, although you can't repair it, but you can't behave too layman, obviously a small problem, a part is broken, and the master goes to replace the entire motor for you.

If the bearing of the motor is broken, the motor will rotate and make abnormal noise, the master told you that the motor is broken, but it is not explicitly said that the bearing can be repaired, you may have listened to the master's words, directly the whole motor.

Therefore, when there is a problem with the electric car, you know that the problem is the first, and it is not easy to be "fooled" by the car repair master. It's not that the car repairer doesn't know what the problem is, but he feels that it is troublesome to repair and not profitable, so it is better to replace it with a new one.

1.When the temperature drops, the storage capacity of some batteries decreases. Specific solution: Pay attention to the ambient temperature when charging.

2.The battery has been used for a long time, and the plates are aging. Specific solution: replace the battery with a new one.

3.Motor, if the motor is old, the carbon brush is seriously worn, the bearing lubrication is not good, etc., it will consume a lot of electrical energy and the input mechanical energy is insufficient.

1.The battery is used for a long time, caused by the aging of the plates;

2.If the motor is old, the carbon brush is seriously damaged, the bearing lubrication is not good, etc., it will also cause the battery car to consume power quickly;

3.As the temperature drops, the battery's power storage capacity decreases;

4.The battery car has a short circuit and so on.

1. The aging of electrical components of electric vehicles has caused the electrical rubber wires to fall off, and there are solutions to the problem of leakage and power run: it is necessary to clean and replace the peeled wires in time, and clean up the dust on the controller and electrical devices. Second, the electric wheel axle card is too tight, or the wheel hub is deformed, which will also lead to an increase in power consumptionSolution:

Turn off the power, hold up the electric vehicle with double support, rotate the front and rear wheels by hand, carefully observe whether the tires are deformed, whether there is gray deposits at the wheel bearings, and there is resistance when rotating (find a new car to compare and feel), and find a mechanic to remove the tires to clean or replace. Third, after the short circuit of the electrical device, it will also cause a sudden increase in power consumptionSolution: This needs to be troubleshooting, in this case it is generally caused by long-term rain erosion, but it is difficult to find, as for which component has a problem, it has to be disassembled and eliminated one by one.

According to past experience, basically the probability of lamps, controllers, circuits and other components is relatively high.

First, the front and rear tires of an electric vehicle are not gasy, which will increase the power consumption of the electric vehicle.

Second, the battery itself, including whether the voltage and current output by the charger are abnormal.

Third, whether there is oxidation in the output interface of the battery, the formation of resistance also affects the speed and mileage.

Fourth, the motor is also a rear-wheel drive machine, and the coil has a slight short circuit or leakage.

Fifth, the throttle is the variable resistance, the resistance value increases and other reasons.

The increase in power consumption of electric vehicles is most likely due to the reduced capacity of the battery to store power, i.e. the battery is not actually fully charged, making it look very power-hungry. In this case, the battery needs to be replaced.

Electric vehicles are very power-hungry for several reasons:

1.The battery life is reduced, the capacity is reduced, and it creates a feeling of power consumption for you.

2.The bearing is aging and lacks oil, and the friction increases after the bearing ages, which makes it difficult to rotate and consumes power.

3. The tire is out of air, and the lack of air in the tire will increase the contact area, and the resistance will naturally increase.

The fact that the electric car consumes a lot of power means that his battery itself is not good, so I think you should change the battery of the battery, which may not be endurance enough.

Electric cars are very power-hungry, what is the reason? In this case, it may be that your electric car may leak, you can find a car repairer to check and repair it for you.

1.The battery is no longer working, and the battery needs to be replaced.

2.The tire is flat or a little flat.

The battery life of the electric vehicle savings battery is two years. If the usage rate consumes power frequently.

If the motor is old, the carbon brush is seriously worn, the bearing lubrication is not good, etc., it will also lead to the fast power consumption of the battery car, the temperature is reduced, and the power storage capacity of the battery is reduced. Specific solutions: pay attention to the ambient temperature when charging, the battery car has a short circuit, etc.

The previous battery can last for 3 to 5 years, and it is only after 3 years that it slowly shows signs of decline. Today's batteries will decay after more than a year of use, and some batteries are still obvious, so that the battery will charge quickly and run less frequently.

Precautions for electric vehicle batteries.

The charging time should not be too long. Many EV users believe that the longer the charging time, the more battery power there is. This is very wrong.

The charging time is generally extended within one hour after the charger is changed. Long-term overcharging can easily lead to battery deformation, water loss and other phenomena. Thus directly jeopardizing battery life.

It is best to use a smart socket. Many electric vehicle users go home from work to charge, and cut off the power when they go to work the next day, in fact, most chargers cannot 100% guarantee that the battery will automatically turn off when the battery is full. The best way is to buy a smart socket and set the time when charging, so that you can solve the problem of resting at night.

It means that your battery is almost at the end of its useful life, that is, it is broken.

After a long period of use, the battery has gone through a charge and discharge process of more than n times, the vulcanization of the plates continues to increase, and the charge-discharge ratio continues to decrease, which will lead to the phenomenon you said.

In layman's terms, your battery has been used for too long and can't store that much power, and of course it won't be able to hold a lot of power.

If your battery lasts for a short time, the battery quality is not good. Or, the battery pack is lagging behind.

Hello answer, I have seen your question and am sorting out the answer, please wait a while Oh 1Tire pressure on the front and rear wheels: The tire pressure on the front and rear wheels must be sufficient, whether it is a tubeless tire or a tire with an inner tube, the air pressure must be sufficient;

2.Brake problems on the front and rear wheels: The easiest test method to determine whether it is a brake problem on the front and rear wheels is to manually push the electric vehicle forward without turning on the power supply to see if the electric vehicle is driving smoothly and whether there is any other resistance.

Answer: Then you can only find the store you bought to solve the problem, see if it is a battery problem, ask whether the controller has entered the water several times, the battery is Yadea's original car battery, and the answer is generally not, you are likely to have a battery problem in this situation.

Thank you for your question.

It is due to the reduction of battery capacity. It would be nice to get a new battery.

Hello, it is recommended that you go to the local after-sales service to test whether you need to maintain the battery.

There are many reasons why electric vehicles consume electricity quickly, first of all, it is related to the hot and cold weatherIf the temperature is relatively high and hot, the chemical current material inside the battery of the electric vehicle is more flexible, that is to say, the battery performance is the best in the high-temperature environment, the total capacity of the battery is also the largest, and the cruising range can also go further.

When the weather is cold, the chemical current inside the battery is relatively stiff, that is, it is inflexible, the total capacity of the battery decreases, and the power is fast at this time, and the cruising range can not run far, that is to say, when charging, the surrounding ambient temperature can not be too high, nor too low, try to charge in a moderate environment, so that the battery is also a kind of protection.

Another reason is that the battery is agedBatteries have a service life, under the premise of correct operation, the battery can be used for about three years, if you add the use of battery repair fluid, you can also increase the life of one year on the basis of three years, battery repair fluid is also known as solubilizer, this liquid can slowly restore the battery to 90% of the power after use, very convenient, of course, serious damage can not be used, so the battery aging can be replaced as soon as possible.

Daily maintenance of electric vehicles

Electric vehicles need to maintain the battery of the vehicle in daily use, and in the process of daily use, the electrolyte of the battery needs to be checked frequently.

Whether it is missing, it is necessary to check whether the battery circuit and each part is aging or short circuit, and the vehicle needs to be started regularly when the motor vehicle is idle, and the voltage of the battery needs to be checked regularly.

The reason why electric vehicles consume power quickly is that the battery active material is inactive and the single battery fails. The details are as follows.

The battery active material is inactive. First of all, you need to know that in summer due to the high temperature, electric vehicle batteries.

The active substance is relatively active, and at this time the battery performance is the best, the capacity is also the largest, and the battery life is relatively longer. In autumn and winter, as the temperature drops, the active material of the electric vehicle battery will become inactive, and the capacity will also decrease.

At this time, the electric vehicle will lose power too quickly and the battery will not be durable. For this kind of problem, users need to avoid charging in a low temperature environment, but should choose to charge in a moderate temperature environment, and after the charger jumps, you can choose to continue floating charging for half an hour.

Battery Precautions:

Pay attention to the charging time, you must pay attention to the charging time when the battery is charging, do not charge it for a day or two, that will not increase the capacitance, but will only make the battery closer to scrapping. Don't charge it for a while and then unplug it, it's still okay to use it once in a while, but if you have too many times, it will definitely make your battery capacity.

It is recommended to recharge it after discharging for about eight hours, so as to ensure its normal use cycle.

In addition, it is necessary to ensure that the number of charging times is not too much. Anyone who knows a little about electric vehicle batteries knows that the more times a battery is charged, the shorter its lifespan. The normal battery life is about two years, and if it is charged frequently, it will naturally not last longer.

Chargers should not be mixedNow many car owners have two or even more electric vehicles, and many electric vehicles are different brands, different models, battery models are not the same, chargers are naturally different, can not be universal. However, some electric vehicle users will often use it in the process of use, and the charging voltage and current do not match, which will cause damage to the battery. The correct way to do this is to have one charger per car.
