What is the dark current of a navigator 5

The dark current of the general car does not exceed 20mA, but the more advanced the car, the more the dark current increases due to the increase of electrical equipment.

Dark current is the current that supplies the car's battery when you turn off the engine and remove the keys (usually a few minutes later).

Hollow door locks, anti-theft systems, electronic clocks, etc. are all dark currents.

The dark current of the car is generally about 20mA and 30mA, of course, the specific situation depends on the configuration of each car, and it may be larger. In addition, the capacity of the battery will also affect the parking time of the car. Generally speaking, the battery is about 60ah.

It is reasonable to say that below 30ma, some cars are only about ten milliamperes, and they are too big to stop for two days as you said.

Your question is very professional, the so-called dark current is not quite the same according to the configuration of the car, different models due to the different vehicle systems, because the system standard value is different, so the dark current value is not very different, so the dark current standard of each car is not the same It is different from the leakage.

The fact that the dark current of modern cars exists, generally in 10-50mA, some models may be slightly larger, different brands, different models of cars are different, battery leakage, first consider the dark current, and then consider whether there is a problem with the line, electrical appliances and batteries.

The standard of dark current value (quiescent current value) of different models of automobiles is different. There are different standards for the dark current value of each model, and the dark current is judged according to the specific dark current value of the model, and the dark current cannot be unified, because the circuit design of each model will be different, and different circuit designs will have different dark currents.

The dark current value of each model has an error range, such as 20mA 5mA, if the dark current of car A is this standard, then when the dark current value of car A reaches more than 26 mA, it can be concluded that it is leakage or fault.

The dark current of car B is also implemented according to the standard of car B. The dark current of the model with a large scale of electronic circuits is relatively large, and the dark current of a small scale of electronic circuits is relatively small, and the difference between them is large.

All cars are tested before leaving the factory.

I only know that the dark current of each car is different.

Here's a reference.

Portable 5-inch or 7-inch navigation charging current should be at least 1A, which is recommended.

You don't have to worry about this.。。 It won't run out of power. Unless your battery is dead.

The unit of electric current is amps, not watts, so I don't know what you want to ask.

Hello, of course it won't be all powered off, the security system won't be powered off, otherwise how to unlock it with remote control, and the burglar alarm is also standby.

It seems to be the control system of the car, I don't remember it clearly, I used to see it on Fortune Qilu, there is a car channel with an introduction, you can go and take a look.

The so-called dark current (the reason why it is called dark current is because it is called dark current in English, so it is literally translated as dark current). It refers to the current that is still flowing when the ignition switch is in the off position (the car is not working) Because of the existence of these dark currents and the natural discharge of the battery, the battery capacity of the vehicle is insufficient when the vehicle is parked for a long time, resulting in the car being unable to start. The existence of dark current, first, some electrical equipment in order to maintain the memory function of data, must be supplied for a long time These electrical appliances mainly refer to computer control units such as audio (remember the last frequency band listened, CD track); There is also air conditioning (memory of the setting of wind direction and wind speed) Second, some anti-theft sensors need long-term power supply to ensure all-weather monitoring function The general car dark current does not exceed 20mA, but the more advanced the car, due to the increase in electrical equipment, the dark current also increases At the same time With the increase of automotive electrical equipment and the increase of battery capacity, it seems that the dark current of the car will be larger and larger in the future The power naturally consumed in about two weeks should have little impact on the start (the battery itself has some self-discharge); If it is an electronically controlled car (because it has more electronic control modules and more power-consuming parts), generally speaking, if it does not start for a week or so, it may affect the normal start.

If it falls below this time frame, it may be a malfunction, or the battery itself is faulty. In addition to the normal loss of electricity, there is also a situation: after the car is used at night for a few days, it will be difficult to start, if there is no leakage, then check the charging system of the car, sometimes if the charging line is not connected to the truth, it may cause the power can not be fully charged into the battery, resulting in the peak of electricity consumption (summer evening), the battery is in a state of semi-loss, and over time, there will be a phenomenon similar to leakage.

Leakage detection is to connect the multimeter in series to the negative electrode of the battery, and the lead of the battery needs to be removed. This is not only time-consuming and labor-intensive, but also easy to lose the customer's data. Measuring dark current is the main detection method to determine whether there is a leakage fault in a vehicle.

Turn off all the electrical equipment of the vehicle, adjust the range of the meter to the "4000mA" gear, pull the jaws and put the meter head on the negative wiring harness of the battery, and judge whether the vehicle has leakage according to the measured data. If the vehicle is activated by the anti-theft system, the measured current value does not exceed 30 50mA, which is normal.
