A supercapacitor (or ultracapacitor), also known as a gold capacitor, electrical double-layer capacitor (EDLC), or electrochemical capacitor (EC), is a type of electrochemical capacitor with high energy density. Compared to traditional electrolytic capacitors, supercapacitors have hundreds to thousands of times higher capacitance, with performance falling between that of electrolytic capacitors and batteries. Supercapacitors charge and discharge much faster than batteries, and their charge-discharge cycles significantly exceed those of batteries.
The main advantages of supercapacitors are:
High temperature resistance: Supercapacitors can operate stably in high-temperature environments, making them suitable for applications with demanding temperature requirements.
Safety and stability: Due to the characteristics of their internal structure and materials, supercapacitors are less prone to failure, such as expansion or explosion, than traditional batteries like lithium batteries, thus offering higher safety.
Longer lifespan: Supercapacitors can have up to 30,000 charge-discharge cycles, exceeding most batteries.
More charge/discharge cycles: Compared to traditional lithium batteries, supercapacitors can undergo more charge/discharge cycles, making them more economical.
Based on these advantages, supercapacitors are ideal for the high-temperature environments of dashcams. When a dashcam separates from the vehicle body due to a collision or other factors, the built-in supercapacitor can provide a few extra seconds of recording time to capture and store the most crucial footage.
P-editor recommends that car owners check whether a dashcam is equipped with a supercapacitor when choosing one. Of course, P-editor highly recommends Polaroid and Pernis dashcams. Whether for motorcycles or cars, every model uses a top-of-the-line supercapacitor, ensuring stable operation and reliable recording under various driving conditions.
