What is the effect of a car charger on a mobile phone?

The car charger has an impact on the charging of the mobile phone battery, which will cause damage to the mobile phone battery, usually the output voltage of the car charger is DC 5V, when the mobile phone battery voltage, try not to use the car charger to charge the mobile phone battery, because the car charger voltage and current are relatively high, which will cause damage to the mobile phone battery. Note: The battery has a specified maximum voltage and current, if the maximum voltage or maximum current is exceeded, the charger will be damaged.

When the car charger is used for mobile phone charging, the power consumption is very small, and the charger power is about the same, so the life of the car battery is basically not affected. In order to make the battery life normal, it is necessary to check whether the battery quality is qualified, the engine ignition should not be too frequent, the ignition time should not be too long, and the charging system should be checked to see if it is normal. Do a good job of maintenance.

On-board charger refers to the on-board charger that is routinely powered by car batteries (12V for cars, 24V for trucks), and is widely used in the field of lithium battery charging for various portable and handheld devices. Such as: mobile phone, PDA, GPS, etc.; The on-board charger should not only consider the actual needs of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP), but also take into account the harsh environment of the on-board battery (transient spike voltage, system switching noise interference, EMI, etc.); Therefore, the power management IC selected for the vehicle charging solution must meet the following requirements at the same time

High-voltage, high-efficiency, high-reliability, low-frequency (EMI-friendly design) switching power supply chips. The car charger is an accessory that is convenient for charging digital products anytime and anywhere with the on-board power supply, saving you battery overhead. This kind of product generally has overload protection, short circuit protection, high voltage input protection, high temperature protection, and quadruple safety protection functions to ensure that you can use it safely.

Why can't you use a car charger to charge your phone?

Car chargers generally do not cause damage to the car. Note that it must be used when the engine is working, the battery is charged by the generator, and then the battery is connected to the car charger for use, otherwise the battery will run out.

Battery power that is too low has an impact on battery life. When the battery is empty, the engine cannot be started to charge, and the battery must be charged with a special charger.

<> "Many friends are in a hurry to go out, so much so that they forget to carry the charger of their mobile phones, so they will choose to charge it in the car. So does charging a mobile phone in the car have an impact on the battery?

Under normal circumstances, if the vehicle is running normally, the mobile phone charging in the car has no effect on the battery, because the car charger used for mobile phone charging is very small, and the power of the charger is only about it, so the use of mobile phone charging will basically not affect the life of the car battery.

However, if the chain quarrel fails, the owner uses the vehicle to charge the mobile phone when the vehicle is turned off, which will consume the power of the battery, which will affect the power of the battery, because the battery is charged and discharged several times, and the battery will often be out of power to reduce the service life.

It can be seen that as long as the owner does not turn off the vehicle to charge the mobile phone, it will not affect the battery, and the daily maintenance of the battery also needs to be paid attention to in order to extend the service life of the battery.

In fact, this kind of question can be answered with a little thought, charging the mobile phone in the car will not hurt the car. The charging current of the mobile phone is not too large, even if it is a 5A high-current fast car charger, its power will not exceed 50W, generally around 45W.

50W power, the battery voltage is 14V after the car starts, and the current is about 14V. The current of the cigarette lighter fuse is at least 10A, and theoretically the cigarette lighter can output about 140W of power. As long as it is below this power, the fuse will not blow.

The fuse above 10A will blow to protect the relevant wiring and protect the battery from over-discharge. It can be seen that the charger power is within the allowable range, and charging on the phone does not have any effect on the car.

The current of the car generator is above 80A, and the power is above 1000W. If the line allows it when driving, then as long as the total power of the load does not exceed 800W, then there will be no problem with the generator. Therefore, many cars are equipped with auxiliary batteries, which will not have an impact on the generator, and the auxiliary batteries can be replenished when driving.

As long as the engine is running, the power supply of the whole vehicle is provided by the generator, and when the electricity consumption exceeds the power supply of the generator, the battery will assist in discharging to fill the gap.

As long as the generator is not discharged at full load for a long time, there will be no problem with the generator. Only if it is overloaded for a long time and the load power is too high, the generator is in danger of burning. The maximum power of a small mobile phone charger is only 50W, and the power is only 1 20 of the generator, which does not affect the life of the generator.

Even if the charger is used after the ignition is turned off, it will not affect the battery for a short time. Taking the smallest capacity battery 45ah as an example, the battery storage capacity is 45 12 = 540wh. The battery retains 1 3 of the charge to start the engine, and the battery usable power is 360wh.

If the charger power is 50w, then it can support the charger to work 360 50 = hours or so.

It will not cause overcharge to the battery, because the car charging system has a set of protection system and regulator, when the battery voltage exceeds the rated voltage, the regulator of the protection system will cut off the excitation coil of the generator to stop generating electricity, so as to regulate the charging process of the battery.

The function of the regulator, the car generator is a silicon rectifier generator, and there is an excitation coil inside the power generation, and the generator generates electricity when the excitation coil has a current. The regulator relies on the voltage signal of the battery to supply power to the excitation coil to control the working state of the generator. After the regulator stops supplying power, the regulator continues to supply power when the voltage is lower than the set voltage, which is an iterative process.

Generally speaking, charging in the car will not have much effect on the phone, but if the voltage is unstable, it may cause the cigarette lighter fuse to blow.

The mobile phone can be charged with the car power supply, but it must be charged with a special mobile phone matcher, because the voltage of the car is 12V, and the voltage of the car is 24V, which cannot be charged directly.

The battery of the car that will not charge the mobile phone provides direct current, which is different from the alternating current on the ordinary socket at home, but the mobile phone itself accepts direct current, even if the original charger is used to charge the ordinary socket at home, the charger of the mobile phone will also convert the household alternating current into direct current and provide it to the mobile phone.

Therefore, although the battery output in the car is direct current, it will not affect the mobile phone itself.

It won't break. It doesn't affect the car.

On-board mobile phone charging has little impact on the car.

Feature: The car charger is to use the car cigarette lighter as a power socket to charge the mobile phone directly. Since the voltage provided by the car is low, only the overload protection circuit inside the car charger is required.

The front end of the car charger socket is designed with a fuse, and when the current exceeds the tolerance range of the overload protection circuit, the fuse will be blown immediately to protect it.

Precautions: 1. Do not use the car charger in a humid environment.

2. Do not store the car charger in a humid environment.

3. The suitable temperature for use is 0-45

4. Keep away from children.

5. Avoid lightning strikes.

6. Unplug the plug in time after charging.
