BMW prompts that the increase in parking discharge indicates that there is leakage in the circuit, or the battery life is less than 30%. First of all, check whether the vehicle has an installation project, and pay special attention to whether the dash cam is connected to the constant power and has been working. The second is to charge the battery in the car.

When the weather is cold, the battery efficiency will decrease. The discharge amount increases, and the owner has not installed a dash cam or any other electrical appliances. It is recommended that the owner check the dormant current, find out the main problem, and it is recommended that the owner replace the original BMW battery, BMW 5 series uses more 12V900A batteries, because there are more electrical appliances in the car, and the installation of low-capacity batteries may not be enough.

After the extended data or the vehicle was towed back to the repair shop, a preliminary inspection was observed, and it was observed that the meter and ** information display showed that the battery was "discharged". Press the horn switch, the sound is very quiet; Turn on the lights, the light brightness is very low. Press the start button, the starter is weak, the engine cannot start, and the battery power is preliminarily judged to be too low.

Connect the charger to charge the vehicle. As the name suggests, the biggest feature of the maintenance-free battery is "maintenance-free". Compared with lead-acid batteries, its electrolyte consumption is very small, and there is basically no need to replenish distilled water during its service life.

It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. Of course, its price will be more expensive than lead-acid batteries. As for the service life, under normal circumstances, the recommended replacement cycle of maintenance-free batteries is about 3 years, which is comparable to lead-acid batteries.

Broadly speaking, the starter uses three components to realize the entire starting process. The DC motor introduces the current from the battery and causes the driving gear of the starter to produce mechanical movement; The transmission mechanism meshes the drive gear into the flywheel ring gear, and at the same time, it can automatically disengage after the engine starts; The starter circuit is switched on and off by an electromagnetic switch. Among them, the electric motor is the main component inside the starter, and its working principle is the energy conversion process based on Ampere's law that we are exposed to in junior high school physics, that is, the action of the energized conductor in the magnetic field.

The electric motor includes the necessary components such as armatures, commutators, magnetic poles, brushes, bearings, and housings.

1. Batteries should be used frequently: for large cities, because the congestion phenomenon is more serious, and the standard restrictions on emissions are relatively large, so some car owners often buy a car but do not use it often, but they do not know that the battery will produce self-discharge phenomenon in the case of long-term non-use, and even scrap phenomenon, so even if the owner is parked for a long time, the car should be started once in a while, and the battery is charged.

2. The car can not be started many times when starting: for the car owner, when starting, do not use the engine uninterruptedly, this situation will lead to excessive discharge of the battery, resulting in damage, so it should be started at an interval of more than ten seconds, and it is recommended to go to the maintenance plant for maintenance after many times of starting, rather than trying to start again.

Common phenomenon:1When the start switch is turned on, the starter rotates at high speed and the engine crankshaft does not respond. This phenomenon indicates that the fault occurred on the transmission mechanism of the starter, which may be caused by wear of the transmission gear or one-way clutch.

2.The starter does not work properly, and the drive gear does not turn. There are many reasons for this, such as problems with the power cord, ablation of the contact disc of the starter switch, and excessive engine resistance.

3.The starter has insufficient power output to drive the crankshaft. A short circuit in the excitation coil and a loss of power in the battery can cause a lack of power in the starter.

4.The starter is running with a harsh sound. This can be caused by a one-way clutch jam or improper installation of the starter.

5.There is a "click" sound when the starter is switched, but it does not work. This phenomenon can be caused by a broken coil or a severe loss of power in the battery.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Questions. The battery is newly replaced, and it runs out of power after parking for a few hours.

After parking, the trip computer shows a large amount of discharge.

BMW shows that the battery will discharge when parked? Check the retrofit, measure the sleep current, and find the missing location.

Is the battery original.

Questions. No, the original car battery of the brand is also this problem, thinking that the battery is not working, so I changed it, and the result is still the same, but I don't know the ** discharge.

If the battery needs to be matched, the original battery has ***, and the ordinary battery does not have ***, so there is no way to match.

It takes a long time to find the location of leakage with professional equipment.

Questions. How to match the battery.

Use the computer to replace the battery, and the brand battery can't do it.

Questions. After changing the new battery, you can play wow.

You need to tell the computer to change the battery, and the computer will adjust the charging amount, this car is very smart.

Failures and methods:

1. First of all, check whether the vehicle has any installation items, such as whether the dash cam is connected to the constant power and has been working. If there is no installation item, it is recommended to check the sleep current.

2. Charge the battery in the car.

3. If there are more electrical appliances in the car, it is recommended that the owner replace the original BMW battery, such as the BMW 5 series uses more 12V900A batteries.

4. Or tow the vehicle back to the repair shop for preliminary inspection, if you press the horn switch, the sound is very small, turn on the light, and the brightness is very low. If the starter is weak and the engine cannot be started, it is preliminarily judged that the battery is too low, and the charger is connected to charge the vehicle.

Batteries are an indispensable part of automobiles and can be divided into traditional lead-acid batteries and maintenance-free batteries.

Because the battery uses lead-calcium alloy as the grid, the amount of water decomposition produced during charging is less, the amount of water evaporation is also low, and the shell adopts a sealed structure, and the sulfuric acid gas released is also very small, so compared with the traditional battery, it has the advantages of not adding any liquid, docking pile head, and long power storage time.

Question: The battery is newly replaced, and it runs out of power after parking for a few hours.

After parking, the trip computer shows a large amount of discharge.

Is the battery original.

The question is not, the original car battery of the brand is also this problem, I thought the battery was not working, so I changed it, and the result was still the same, but I didn't know the ** discharge.

If you need to use professional equipment to find the location of the leakage, it takes a long time to ask how to match the battery.

1. I installed power-consuming equipment, which increased the burden on the battery and caused the battery to lose power. Such as dash cams, subwoofers, remote controls, etc. 2. The original car battery is in stock for too long, there is a lot of driving in the city, it is not charged in time, and the battery is aging prematurely.

Hello, is there an installation that causes battery leakage.

Summary. Hello, what does it mean when BMW shows that the battery discharges increased when parked? This is a hint that the battery is too low, and you can use a battery tester to detect the health of the battery, which can give a hint of whether to replace the battery or need to be charged.

If there is no detector, charge the battery first, if it is fully charged, it is also prompted, you need to replace the battery, BMW needs to make a battery replacement record to replace the battery, and the battery is an AGM battery. I hope mine can help you.

There may be several reasons for the large discharge of the Baohezhi carriage battery:

Do not use the vehicle for long periods of time. If the BMW is not used for a long time, the battery will gradually lose its electrical energy. If it is too long, the battery may be completely discharged, making it impossible to start the vehicle.

The vehicle circuit is bent in a short circuit. If there is a short circuit in the BMW circuit, the electrical energy will be lost directly through the short-circuited part, resulting in a large discharge of the battery.

Generator or charger failure. If the BMW's generator or charger fails, the battery cannot be recharged, causing the battery to discharge.

The temperature is too low. In extremely low temperatures, the battery's electrical energy is also lost. This is because low temperatures will affect the rate of chemical reaction of the battery, and the capacity of the battery will be reduced quickly.

It's very important, and it's also a point that is usually overlooked! After the ignition is turned off, the generator does not generate electricity, and directly uses the battery power, and excessive discharge will cause irreversible damage to the battery. It is often encountered that the vehicle goes to the film, and the result is that the vehicle cannot be started, the reason is that when the film is applied, the master does not ignite the vehicle completely, resulting in the power consumption of electrical equipment.

Frequent short-distance driving will accelerate the loss of the battery, and due to frequent short-distance driving, the generator will not be able to fully charge the battery, which may also cause the battery to be fed. If you usually use the vehicle for commuting in the city, it is recommended to drive more than 30 minutes on the highway every 5,000 km. Let the generator charge the battery!
