In recent years, with the popularization of automobiles, the types and quantities of automotive electronic products have increased tremendously. Many of these products are equipped with two power supply methods, one comes from the car itself, and the power is supplied through the cigarette lighter interface of the vehicle. The other comes from a backup power supply. After the power of the cigarette lighter is turned off, the backup power supply is used to maintain the equipment.
As a new type of energy storage device, supercapacitors have received extensive attention from researchers in the field of electronic technology. At present, the main research and application are on the energy of electric vehicles, either to form a composite power system with batteries, or directly as a power source to solve the power problem of electric vehicles. In fact, in vehicle electronic products, the application prospects of super capacitors are also very broad. The following will focus on the super capacitor of the driving recorder, that is, the application of the super capacitor on the driving recorder.
A backup power supply is required during the use of the driving recorder. During the driving of the vehicle, the backup power supply is charged through the cigarette lighter interface. When the cigarette lighter port power is cut off or parking, the driving recorder needs backup power to provide enough power to complete the shutdown process, including video storage, secondary power-on detection, and shutdown of the main control and peripherals.
Currently, most driving recorders use liquid lithium-ion batteries as a backup power source. However, considering the special scenarios of the driving recorder, such as long-term use, or the direct sunlight temperature in the car can reach 90°C when parking in summer, these are extremely disadvantageous to the storage and operation of liquid lithium-ion batteries, and there is a hidden danger of bulging explosions. But using super capacitors, through reasonable circuit design, there will be no such hidden dangers, which is very suitable for application in driving recorders.
