Supercapacitors can replace car starting batteries

Can supercapacitors be used instead of car starter batteries?

Supercapacitors are used as vehicle starting power sources, with higher starting efficiency and reliability than traditional batteries, and can completely or partially replace traditional batteries.

It is different from traditional chemical power sources and is a power source with special performance that lies between traditional capacitors and batteries. It mainly relies on double layers and redox pseudocapacitive charges to store electrical energy.

But there is no chemical reaction during its energy storage process, which is reversible, and it is precisely because this supercapacitor can be charged and discharged hundreds of thousands of times repeatedly. It has the characteristics of short charging time, long service life, good temperature characteristics, energy conservation, and green environmental protection.

Supercapacitors can be widely used in various application scenarios, such as auxiliary peak power, backup power supply, storage of renewable energy, and alternative power supply. They have a very broad development prospect in industrial control, wind and solar power generation, transportation vehicles, intelligent meters, electric tools, military industry, and other fields, especially in some application areas where they have significant performance advantages.

1. The earliest applications of electronic devices include the memory system of our computers, the flash of cameras, and the backup storage power of audio equipment.

2. In the automotive industry, supercapacitors in plug-in hybrid vehicles are mainly combined with batteries to form intelligent start stop control systems.

(1) Supercapacitors can quickly and efficiently absorb the regenerative energy generated by electric vehicle braking;

(2) The supercapacitor provides power to the intelligent start stop control system motor during acceleration and hill climbing, extending the battery's lifespan.

3. Large size supercapacitors can be used in the braking systems of trains and subways, saving 30% of energy.
