What happens when a car uses high power appliances?

1.When the car starts, under the condition that the generator generates electricity normally, its output voltage will be higher than the voltage of the battery, and the generator will supply power to all electrical equipment (except the starter) and charge the battery at the same time; At this time, the battery exists as a load, it no longer supplies power to the electrical equipment, but needs the generator to charge it, and it is also consuming the power of the generator. Only when there are too many electrical equipment and the power consumption exceeds the power supply capacity of the generator, the battery will assist the generator to supply power to various electrical equipment, and the battery is discharged at this time, which belongs to an auxiliary power supply.

2.If there is a high-power electrical device in the car, and its power consumption exceeds the power supply capacity of the generator, the battery will participate in the work and also supply power to the device. Note:

At this time, the generator is no longer able to charge the battery, and all the electrical energy is given to this high-power electrical equipment except for maintaining the normal operation of the car, and it is not enough, and the battery is needed to assist. In this case, the battery is only discharged and not charged, and it will be damaged after a long time; If the battery is deeply discharged, it cannot be restored later. Therefore, when installing electrical equipment in a car, it is necessary to fully consider the bearing capacity of the generator and battery.

3.It is also important to note that high-power electrical equipment can also affect the normal operation of the car and increase the fuel consumption of the car. Some veteran drivers should remember that there used to be some three-cylinder engines, such as the Xiali.

Otto and others, these cars are idling.

When the headlights are turned on, the engine will immediately shake violently, and only by increasing the engine speed will the shake be reduced, but the car will still accelerate weakly. This is because the headlights consume a part of the electrical energy, so that the ignition system gets less electric energy, the ignition energy is reduced, and the engine combustion becomes worse, which is commonly known as "power grabbing". This is a typical case of high-power electrical equipment affecting engine operation.

If such electrical equipment is installed in today's cars, I believe that there will be such consequences.

1. The use of high-power electrical appliances in the car will burn out the fuse, the circuit will be broken, and the electrical appliances will not work.

2. The current is from the live wire to the zero line, you install a fuse on the live wire, if the electrical power is overloaded, the fuse of the live wire will blow safer.

3. Install a fuse on the neutral line, if it is blown off, the current will flow back to the power line of the electrical appliance, and the power line of the electrical appliance is live. It's not safe.

Summary. This is the advantage of replacing a high-power battery. The amount of stored electricity is relatively large, that is, for example, you have this.

When the engine is not started, the time used for the electrical appliances on the car is relatively long. Then you have more stored power, that is, even if the battery has a slight feeding problem, it still has more power, and the engine can start normally. It is the benefits of these aspects, and the others are the same as the original, without any impact.

1. If you often use the car for short distances, the battery is always in a state of not being full. Then the use of a car car washer will definitely consume electricity, and it will only use up some electricity in a short period of time and will not hurt the battery.

2. If you often go long distances, or small long distances to and from work. Then the battery is always full, and occasionally using such a small amount of power for a long time will not have an effect.

3. According to the law of conservation of energy, all the electricity consumed is ultimately converted by gasoline. So in the end, the oil will still be burned. When the battery is not satisfied, the generator is driven by the engine to charge the battery.

4. Injury to the battery only occurs when it is over-discharged. Maybe there is no over-discharge when using the car washer, but when the car is used up and started, a lot of current is required, which will hurt the battery.

Power refers to the work done by an object per unit of time. The higher the power, the higher the speed, the higher the top speed of the car. Maximum power is often used to describe the dynamic performance of a car.

Engine power is usually expressed in kilowatts (kW) and sometimes horsepower (ps). Horsepower is a different representation of power, and its conversion ratio is: 1 horsepower (ps) = kilowatts (kw).

Power is defined as: the work done per unit of time. For automobiles, it is the energy generated to supply the movement of the car in a certain period of time.

Power = Power * Speed. Assuming that the weight, resistance and other conditions of the car are the same, then the car with more power must have a faster speed; If the speed is the same, the more powerful the vehicle weighs more.

Engine torque is usually expressed in Newton-meters (n·m). Torque reflects the torque output from the crankshaft end when the engine is running, and the greater the torque, the engine outputs"Energetic"The bigger it is, the better the car's ability to climb hills, start and accelerate midway.

However, in the process of driving, whether it is power or torque, it is not a fixed value, they will change with the engine speed, among them, the maximum power and the maximum torque have corresponding engine speeds.

I don't think so. Because high-power appliances have nothing to do with the engine, they will not have any effect.

The modification of high-power electrical appliances in the car will not affect the engine, but it will increase the working pressure of the generator and battery, and it is likely to cause the car battery to lose power and cannot be started.

To put it simply, if the electrical appliance you use exceeds the limit of the battery, then the motorist's main control computer board will give an alarm, and if you use the cigarette lighter directly, then the insurance will burn directly. Also, to put it simply, your thing is not high-power at all, there are some real changes to the audio, many of them have not changed the battery, those power is more than 2000W, it's no problem, are you still worried about this? If you are really worried, add a capacitor to the output of the battery, which can protect the battery.

The modification of high-power electrical appliances in automobiles will affect the service life of automobile engines.

1。High-power electrical appliances include: headlights, audio, ***, etc.

2。Under normal circumstances, the generator can also generate electricity normally without installing high-power electrical appliances in the car, and it will not cause the battery to lose power when the car is running normally. However, it is best not to use it for a long time when the car is stopped (that is, when the engine is turned off), otherwise it will cause the car battery to lose power and reduce the battery life.

3。When the car is moving, or after starting, you can turn on all or all the electrical appliances according to your needs, which will not cause power loss.

4。Navigation radar, ***, etc. are high-power equipment.

Hello, yes, you need to buy an inverter, but this will consume a lot of car battery.

There are high-power electrical appliances in the car, such as the starter, which belongs to a high-power electrical appliance. In general, it is rarely used elsewhere.

Hello, it is possible, but it requires an inverter, but it consumes a lot of battery.

Cars can't use high-power electrical appliances, more than 30% of the original high-power electrical appliances will burn out wiring, switches, relays, and computers
