When talking about new energy vehicles, we will think of super capacitors and film capacitors. Both supercapacitors and film capacitors make contributions to electric vehicles by virtue of their superior performance. This article is going to talk about the outstanding features and advantages of supercapacitors.
Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. It is different from the traditional chemical power supply. It is a power supply with special performance between traditional capacitors and batteries. It mainly relies on electric double layer and redox pseudocapacitor charge to store electric energy.
Outstanding features of super capacitors:
1) The charging speed is fast, charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacitance.
2) The cycle life is long, the number of deep charge and discharge cycles can reach 1 to 500,000 times, and there is no memory effect.
3) High current discharge capability, high energy conversion efficiency, low process loss, high current energy cycle efficiency ≥90%.
4) The power density is high, up to 300W/KG~5000W/KG, which is equivalent to 5~10 times of the battery.
5) The product raw material composition, production, use, storage and dismantling process are free of pollution, which is an ideal green and environmentally friendly power source.
6) Simple charging and discharging circuit, high guarantee factor, maintenance-free for long-term use.
7) Good ultra-low temperature characteristics, wide temperature range -40℃～+70℃.
8) The measurement is convenient, and the remaining power can be read directly.
9) The capacitance range is usually 0.1F--1000F.
Advantages of super capacitors:
1) A farad-level capacitance is achieved in a small volume.
2) No special charging circuit and control discharging circuit are required.
3) Compared with the battery, overcharging and overdischarging will not have a negative impact on its service life.
4) From the perspective of environmental protection, it is a kind of green energy.
5) Super capacitors can be welded, so there are no problems such as weak battery contact.
The above content is the characteristics and advantages of super capacitors. Understanding the performance of capacitors is helpful before using them.
