“Chongqing made” supercapacitors will be unveiled at the Zhibo Fair, allowing new energy vehicles to run farther

When it comes to new energy vehicles, many people are worried about the problem of car batteries. How many kilometers can they use? How long does it take to charge a single charge? Does the battery last for a long time?

This year’s Zhibo Fair, Chongqing Zhongke Chaorong Technology Co., Ltd., invested by Chongqing High-tech Zone Jinfeng Electronic Industrial Park and Chongqing Industrial Guidance Fund-Beixin Capital, will bring self-developed supercapacitors.

Supercapacitor is a new type of energy storage device between traditional capacitors and secondary batteries. It has the characteristics of fast charge and discharge speed and high energy storage density. It can complete charge and discharge and realize charge and discharge cycles in seconds. Running more than a million times

According to the relevant person in charge, the supercapacitor developed by the company improves the storage energy density of the capacitor from the two aspects of the rated voltage and capacitance of the capacitor on the basis of ensuring other characteristics of the capacitor. For example, the energy density of capacitors at home and abroad is usually 5-8Wh/kg, and the energy density of supercapacitors of Zhongke Chaorong is down to 13-15Wh/kg, which is more than twice that of similar products.

In practical applications, supercapacitors can maintain high power and high stability, whether used alone or in combination with batteries, to meet the needs of many industries such as transportation, wind power and power grid.

For example, an electric car in a city adds a set of supercapacitors to the battery module, which can effectively reduce the battery consumption speed, extend the battery life, and let the car run longer and farther.

The reporter learned that the company has completed the tens of millions of angel round financing. In April this year, the construction of the 2,200 square meters supercapacitor pilot base in Jinfeng Park was completed. At the end of June, the production line was opened and the 3.2V capacitor product was off the assembly line. At present, the company is embarking on the research and development and production of a series of products, and is expected to fully enter the market in 2020.
