As an essential vehicle safety product, the driving recorder can record the video images and sounds of the entire driving process of the vehicle, providing strong evidence for traffic accidents, and can also monitor when the vehicle is parked. Driving recorders are generally installed after the vehicle leaves the factory, and with the rapid development of the original equipment market, driving recorders are increasingly becoming standard configurations for new cars when they leave the factory.
01 Dash Cam's requirements for backup power supply
In response to the industry's higher requirements for backup power storage products in terms of high temperature resistance, safety performance, cycle life and reliability, YMIN has launched a series of high-reliability supercapacitors that have passed the AEC-Q200 certification, providing a safer and more reliable energy storage solution for driving recorders.
02 Dash Cam · Backup Power Solution
During the driving process, the dashcam is powered by the vehicle's internal power supply and charges the backup power supply.
When the power supply in the car is cut off, the backup power supply needs to provide enough power to ensure that the dashcam completes the shutdown process, including video storage, secondary power-on detection, and shutdown of the main control and peripherals.
Most dashcams use lithium batteries as backup power supplies, but in actual applications, lithium batteries face many problems: complex battery management circuits, long-term cycle charging and discharging lead to battery life decay, lithium batteries cannot work normally in low temperatures in winter, and the temperature in the car can reach 70-80℃ when parking in high temperatures in summer. The temperature resistance of lithium batteries is poor. These problems will affect the normal operation of the dashcam and even pose safety risks of battery bulging or explosion.
YMIN supercapacitors provide dashcams with a backup power supply solution with strong high and low temperature resistance, high safety factor, and long cycle life, overcoming the various limitations of lithium batteries and ensuring the efficient and safe operation of the product in various environments.
03 Advantages and selection of YMIN supercapacitors
Strong resistance to high and low temperatures:
The operating temperature range of supercapacitors can cover -40℃ to +105℃, meeting the requirements for the use of dashcams in extreme environments. Whether in cold winter or hot summer, supercapacitors can work stably and are not affected by temperature changes. They are especially suitable for the strict requirements of the original equipment market for high temperature environments (such as the temperature in the car in summer can reach 70-80℃).
High safety factor:
Avoids the safety risks of lithium batteries such as leakage, fire, and explosion. Even under extreme conditions such as high temperature and high humidity, the safety of supercapacitors is still better than that of traditional batteries, which can provide more reliable protection for dashcams.
Long cycle life:
The cycle life of lithium batteries is generally only a few hundred to a thousand times, and supercapacitors can usually withstand a cycle life of more than 500,000 times, which can effectively extend the service life of the equipment and reduce maintenance costs.
Conclusion
As a backup power source for dashcams, supercapacitors have simple circuit design, a wide operating temperature range, excellent high and low temperature resistance, high safety, and ultra-long cycle life. They replace traditional lithium batteries and become a more ideal backup power solution, which strongly supports the stable operation of dashcams (OEM market) in various environments.
