According to the different parking monitoring principles of the driving recorder, the damage degree of the battery is different after continuous working for 24 hours, and some driving recorders have no damage to the car battery at all! With the increasingly complex driving environment, it has become a trend to buy and install driving recorders, and the demand for 24-hour uninterrupted monitoring is also increasing.
24-hour uninterrupted video recording, some tests on the battery. First of all, we should understand the installation steps of the driving recorder and how to make the driving recorder power on. Generally, the driving recorder will find a normal power supply through the OBD interface or fuse. Ordinary power supply is direct power supply, so it is necessary to know the positive electrode of the battery. There are also driving recorders that use ACC gear for power supply. ACC gear power supply means that when the car is in gear, the driving recorder will work.
The 24-hour monitoring driving recorder is generally powered by a constant voltage power supply. But the only disadvantage of normal power supply is battery loss, which easily leads to battery exhaustion. Therefore, the engine cannot be started. So in order to take this into account, the under-voltage protection function will be added to the driving recorder. When the battery is less than half full.
When the voltage is lower than 13.4V, the battery fault light is on, and it is difficult to start the car. The fully charged battery can be used for 48 hours, reaching the limit of the driving recorder. Actually, we need to consider more aspects. The battery may leak electricity, and the current when the car is in sleep mode will consume electricity and be shortened.
The so-called driving recorder is to record the events during driving. If you want to monitor while parking, it is best not to do so, which will cause some damage to the battery and cause the car to fail to start for a long time. The tape recorder is plugged into the socket of the car cigarette lighter. In this case, after the car key is removed, the cigarette lighter will be powered off in about 15 minutes.
The recorder may continue to work with its own lithium battery or may not have its own lithium battery. After the power is cut off, neither the battery nor the cigarette lighter will work, so that the battery will not be over-discharged and will not affect the battery. The video recorder is directly connected to the battery, which is specially set by the owner to realize 24-hour uninterrupted video monitoring. After the car is turned off, the driving recorder takes electricity directly from the battery. In this case, it doesn't matter if you don't drive for hours.
However, if you don't drive for a few days, the driving recorder will always be on, and the battery will eventually be dead, so you can only charge it before driving. If this happens frequently, it will affect the life of the battery, and it must not be forgotten that the battery has the characteristics of self-discharge, if the battery is stored for too long or the vehicle is parked for too long.
It is best to unplug the battery connector (first unplug the negative electrode, then unplug the positive electrode, then unplug the positive electrode and connect the negative electrode, otherwise it will easily damage the electrical components). In this case, charging the battery once in the second half of the year can ensure the rejuvenation of the battery; The system and other auxiliary equipment will consume electricity, and the driving recorder is of great significance in the driving process of the vehicle, which effectively guarantees the driver's driving safety, but I don't think there is much entanglement in the recording of the vehicle after the flameout.
The damage is too great, which is far less practical than installing a camera near the vehicle. Especially in winter, the battery capacity decreases, and normal wear and tear will cause the vehicle to fail to start, and the loss of the additional recorder is the chief culprit leading to battery power supply.
