The power supply is small, and if you want to bring high power appliances, what will happen?

Many people have a misconception that the battery is the power supply on the car, but in fact, this is not right, the generator is the real power supply on the car. 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.

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.

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 old drivers should remember that there used to be some three-cylinder engines, such as Xiali, Otto, etc., these cars turn on the headlights at idle, and the engine will shake violently immediately, only by increasing the speed of the engine, the shake will 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.

Phenomena such as power supply heating and output voltage drop.

Hello: 1, the power supply drives the load that exceeds its own power, and it will be in [OverloadThere is a possibility of burning.

2. At the same time, the voltage of the load side will appear [Volatilityto affect the load performance.

When the power supply is insufficient to meet the power supply demand of the whole machine, there are three main consequences.

1. The power supply of the processor and graphics card is insufficient, and the performance is reduced when the occupancy rate is high, and there is inexplicable lag.

2. The power supply is overloaded with a small amount for a long time, resulting in accelerated aging of components and finally damage to the power supply.

3. The power supply is overloaded in a short period of time, resulting in the bursting and burning of components, and the impulse current causes the internal components such as the motherboard and memory to burn out, and in serious cases, it causes disasters.

Bigger is not better. The higher the power supply, the higher the requirements for the manufacturer's design and manufacturing level, because the size of the power supply is basically fixed, and to make a more powerful power supply, it is necessary to use the limited internal space more efficiently.

There are two concepts that need to be clarified about the power of a power supply, namely the rated power and the maximum power. The rated power is the power that the power supply can output stably for a long time, and the power supply can maintain a continuous and stable output at this power, which is also the parameter we should prefer.

In order to mislead consumers, some power supply manufacturers mark the maximum power on the power supply, which refers to the peak power that the power supply can output in a short period of time, and the power supply can not be maintained stable for a long time under this power.

The power of the power supply is not as large as possible, first: the power of the power supply is larger, then the violent tremor of this product will be relatively high. Second, if the power you need in Zhizhen is relatively small, and you use a high-power power supply to supply power, it is a knife for killing chickens.

Just like our car battery, it is not that the larger the capacity, the better, but the number of electrical appliances on the car.

If the power supply of the computer is low, it may cause the following problems:

1.The computer does not boot properly or freezes frequently.

2.During the operation of the vibrillatory car, the voltage will be unstable, resulting in damage to the equipment.

3.The performance of the computer has deteriorated, and it cannot meet the demand of high burdens.

4.The computer will have problems such as noise and heating.

Therefore, it is recommended to choose a power supply that is suitable for your computer's configuration to ensure the normal operation and stability of your computer.

Is it the same as the excessive total power of the electrical appliances used and the excessive current, not necessarily, it is necessary to divide different situations. Because the electrical power of the consumer is equal to the product of the rated voltage and the rated current, that is, p=ui. If the rated voltage of the appliance is the same, the greater the electrical power, the greater the current, and vice versa, the smaller.

If the rated voltage is different, the size of the rated current is not simply proportional to the electric power, and the influence of voltage should be considered. No, that's not true. According to the formula of electric power, the electric power is equal to the voltage multiplied by the current, so the greater the electric power, the greater the current is not necessary to determine according to the voltage situation.

This statement is accurate if the voltage of the circuit is fixed. If the electrical power is high and the voltage increases dramatically, the current may remain the same or even decrease. In fact, the power is equal to the voltage multiplied by the current, the current is certain, the higher the voltage, the greater the power; The voltage is constant, the higher the current, the greater the power.

The voltage of the user's electrical appliances is generally constant, including 380 volts, 220 volts, etc. Hope it helps. If my answer is helpful to you, please give a thumbs up (rate it in the bottom left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!

Under normal circumstances, the power of the power supply is not less than the power of the electrical appliance.

Without considering the loss of wires, the actual output power of the power supply = the power consumed by the consumer.

If the loss of the wire is considered, the output power of the power supply = the power of the consumer + the loss power of the wire, then the output power of the power supply is greater than the power consumed by the consumer.

That's a must, otherwise the power supply won't be able to bring electrical appliances. Moreover, the power supply should be selected when choosing.

Of course, this is general knowledge!
