The Supercapacitor Electric Bus Is Adopted in China

One of the interesting things that you can see in China is Capa buses. The word Capa takes from one of the parts known as a supercapacitor. So, what are the things you should know about the supercapacitor electric bus in China?


An electric bus can run because of batteries. The supercapacitor electric bus is using a supercapacitor to run the engine. One of the differences is the charging time. A supercapacitor can charge much faster than batteries. That’s why this type of bus is more efficient and reduces the cost of batteries for electric vehicles. Nowadays, the e-buses only have to stop at specific points that provide a charging machine. The drivers don’t have to wait for the supercapacitor charging process too long. As a result, they can continue to get passengers. It means it keeps drivers productive.

Fast Charging Process

The drivers only need to charge the ultracapacitor batteries in a couple of minutes. The bus companies or the government prepare the system well. They install the charging devices at the bus stops. Bus drivers and passengers don’t have to wait for too long only because of the unfinished charging process. They can keep going just like when they ride an ordinary bus.

Longer Lifespan

One of the reasons why bus companies in China are joining the e-bus project is because of the lifespan of the supercapacitor. A supercapacitor has a longer lifespan than batteries. Supercapacitors can last for between 10 to 20 years, whereas a lithium-ion battery or lead-acid battery can only last for up to 5 years. A supercapacitor can also go through one million charge cycles, whereas a lead-acid battery is not more than 1.000 charge cycles.

The Bus Companies that Have Used Supercapacitor Buses

There are at least five different bus companies in China that launch their e-buses. Those bus companies are Yutong Bus, Xiamen King Long Motor Group, BYD, and Nanjung Golden Dragon Bus. The Group even takes its three subsidiaries to launch e-bus that are Higer Bus, Xiamen United Automotive, and Xiamen Golden Dragon Bus. Those top 5 bus companies in China support the project by releasing up to 17.011 vehicles.

E-bus or Capa bus become a massive environmentally-friendly public transportation in China. That’s why experts predict that this project will keep growing significantly until 2023 and the next few years. The most important thing is that China can reduce the total of its emission as well as to keep the environment safe.
