First, solar energy is only an auxiliary energy source. It mainly relies on the battery of the electronic tag to store the electricity from the capacitor. Therefore, a little light is enough. There is a problem with the position of the electronic tag installed by the installer. The black area with small marks behind the LED (the place where the light transmission you mentioned is low) is the area specially used to install the OBU
etc. How long does the battery last?
The OBU does not have a power switch. It is on when it leaves the factory. It has one or two rechargeable batteries inside and a solar panel outside. See the image below
There are two batteries on the left side of the image above
The solar panel on the right side of the image below underneath can charge the internal battery.
ETC equipment is toThey come with their own power supply. Usually, the battery life is 3 to 5 years. The latest OBU is equipped with solar cells, so no power supply is required. . Under normal circumstances, after three years of use, if there is no beep when the card is inserted into the ETC device, it means it is powered off. ?
Obu is now equipped with solar panels. When users use them, they will automatically charge under sunlight. However, that doesn't mean it doesn't have other batteries. It also has a spare lithium thionyl chloride battery, which is usually used to guarantee power when the solar battery is discharged. If used normally, as long as your battery has no defects, it will normally last several years.
At present, the common use of electronic labelsETC solar batteries contain 18650 lithium batteries internally and are powered by solar charging panels externally. There is no need to worry about what to do if the ETC runs out of power. ETC batteries are normally used for 3 years. If quality problems arise during the 2-year warranty period, ETC equipment may be taken to an ETC handling point or ETC service point for repair/replacement.
What to do if the solar ETC is discharged? Actually, you can use an ETC charger to charge it. If the internal battery of the ETC device is exhausted, you must replace it with one. new battery ETC. Of course you can always use ETC. The charging cable is used to charge it (electronic tags without ETC charging cable can only be used at ETC service points to replace the battery), which allows emergency use. beat herie ETC thereafter.
The instruction manual does not strictly define how often ETC should be charged. For users who do not use the ETC frequently, it is recommended to charge the ETC device every 3 months to avoid affecting the lifespan of the ETC. battery due to self-discharge. For ETCs that use wired power and are not used for a long time, it is also recommended to charge them once a month. ?
If necessary, you can take the device to a service point to replace the battery, or you can buy the battery online and replace it yourself.
