The recent explosion of new energy vehicle batteries has aroused widespread social concern, exposing a long-standing safety blind spot – most new energy vehicles have not yet configured independent backup power systems in the design of key escape channels such as doors, windows, and tailgates. Therefore, the role of emergency backup power supply for doors cannot be underestimated.

Backup power supply solution · Supercapacitor
In addition to the insufficient performance of traditional lead-acid batteries used in vehicles in low temperature environments, when the battery has thermal runaway or explosion, the high-voltage power supply of the entire vehicle will trigger forced power-off protection, causing the electronic door locks and window control systems to be instantly paralyzed, forming a fatal escape barrier.
In the face of safety issues caused by insufficient battery performance, YMIN launched a door backup power supply solution – supercapacitors, which have high safety, wide temperature range, and long life. It provides “permanent online” power guarantee for escape channels and becomes an inevitable choice for emergency backup power supply.

YMIN Supercapacitor · Application Advantages
· High discharge rate: YMIN supercapacitor has excellent high-rate discharge capability, which can provide high current output in a very short time, meeting the demand for instantaneous high current of the door backup emergency power supply. When the vehicle encounters low battery or fault, the supercapacitor can respond quickly and provide sufficient energy support to ensure that the owner can complete the unlocking operation in a very short time.
· Good low-temperature performance: YMIN supercapacitor can maintain stable working performance under extremely cold conditions. Traditional batteries often have problems such as a significant drop in capacity and difficulty in starting at low temperatures, while the capacity attenuation of supercapacitors is extremely small. Even when the temperature drops to -40℃ or lower, it can still provide sufficient energy output to ensure that the door backup emergency power supply can still operate reliably in severe cold weather.
· High temperature resistance and long life: YMIN supercapacitor can work stably under high temperature conditions up to 85℃, ensuring a service life of up to 1,000 hours, continuously providing stable power output, and reducing maintenance and replacement frequency. The characteristics of high temperature resistance and long life meet the needs of the original equipment market for high-performance and high-reliability power components, ensuring that the doors can be reliably started in an emergency in various environments.
· Good safety performance: Compared with traditional batteries, YMIN supercapacitors provide a safer and more reliable emergency power solution. Supercapacitors do not contain flammable or toxic substances, and will not leak, catch fire or explode due to external impact or damage.
