The supercapacitor is a type of capacitor that is capable of storing a large amount of electrical energy in a small space and is used to power the device to ensure continuing to operate even in the event of a power failure. This makes it ideal for use in portable electronic devices, where space is at a premium.
Unlike a traditional capacitor, which stores energy by means of an electrostatic field, a supercapacitor stores energy in an electrochemical double layer. This allows it to store a much larger amount of energy in a given volume, and to discharge it quickly when needed. As it has fast charging and discharging speeds, stable & safe performance, and environmental protection, the supercapacitor is very suitable for automotive electronics applications such as driving recorders/dash cams (GPS).
The use of supercapacitors in driving recorders (GPS), through reasonable circuit design, is safe and environmentally friendly and does not have the risks of explosion. Supercapacitors guarantee more safety, withstand the most frigid cold and intense heat, and have a longer lifespan than batteries.
The use of a supercapacitor in a dash cam has several advantages.
For one, it allows the device to continue operating even if the vehicle's battery fails or is disconnected. This is important because a dash cam's primary function is to record events that take place on the road, and if it were to shut off in the middle of an incident, the recording would be incomplete.
Additionally, the use of a supercapacitor allows for a much faster charge and discharge time than a traditional battery. It allows 100,000 charge and discharge times, with a safe and stable host power supply. This means that the dash cam can be quickly powered on and ready to record, even if the vehicle has been parked for a long period of time. The built-in RTC high-capacity battery operates normally even power off within 2 months
Last but not least, its fire and explosion-proof material provide safety first. It can withstand extremely higher and lower temperatures geographically so that it can extend the product's life for years.
Overall, the use of a supercapacitor in a dash cam is a key technology that helps to ensure that the device can continue to operate reliably and effectively, even in challenging conditions. By storing a large amount of energy in a small space and allowing for quick charge and discharge times, the supercapacitor helps to make the dash cam a valuable tool for recording events on the road.
