The Chinese company Ningbo CSR New Energy Technology has delivered to its parent company CSR Zhuzhou Electric Locomotive its first batch of 5000 supercapacitors 7500 Farads. This is the largest mass production in the world of supercapacitors with such capacitance.
The most advanced countries in the field of supercapacitors are South Korea, the United States, Japan and China. Today there are more than a dozen manufacturers worldwide able to supply large quantities of supercapacitors.
China started to develop supercapacitors since the 1990s. In recent years, under the leadership of the manufacturers of trains and trams of South China, significant progress has been made throughout the supercapacitors design chain: structure, preparation equipment, manufacturing, systems integration... All this to obtain a series of inventions and innovations with their own intellectual property, so breaking a number of constraints to the development of supercapacitors, but also to break the blockade of foreign technology. This has enabled China to join the few countries with the capacity to do research and development on high-power supercapacitors.
Currently, many cities work with the Chinese company CSR Zhuzhou to develop trams without overhead lines and buses with ultra fast charging thanks to supercapacitors.
Ningbo CSR New Energy Technology Co., LTD.
The CSR Ningbo New Energy Technology company was founded in February 2012 with a registered capital of 88 million RMB. This is a joint-venture between RSE and SPSCAP. It is a company specialized in the development, manufacture and sale of supercapacitor electrode and single cell and modules supercapacitors.
The company produces CSRCAP supercapacitors from 350 to 9500 Farads. It has a large-scale production line of ultracapacitors, with the ability to produce high voltage supercapacitors modules. The highest voltage of the module can achieve 1500V.
His market includes a series of emerging industries, such as rail transport, electric vehicles, wind power, smart grids and military equipment. The company aims to be in the top three global industry in 2015.
It already makes a few years that supercapacitor buses circulate in China. See article The electric bus supercapacitor is adopted in China. Some buses have been victims of fire starts, but control of supercapacitors has since been improved. For proof, Ningbo New Energy Technology CSR has on its website a test video of its supercapacitors CSRCAP 7000 Farads. Molested, crushed, punctured or burned, the supercapacitor does not fire and does not explode.
