According to CSR Zhuzhou Machinery Co., Ltd., on April 16th, the company’s subsidiary, Zhejiang CSR Tramway Co., Ltd., supercapacitive energy storage modern tram: 18-meter supercapacitor energy-storage BRT bus and 12-meter super capacitor energy-storage bus Ningbo went offline and debuted.
Zhou Chouhe, Chairman of CSR Zhuzhou Motor Co., Ltd. introduced that the above-mentioned pure electric buses do not need to set up an over-the-air power supply network. They only need to set up charging piles at the bus stop and use the passengers to get on and off within 30 seconds to fully charge the electric power and maintain operation for more than 5 kilometers. , can be cycled online operation. When braking and downhill, it can also convert more than 80% of the braking energy or potential energy into electrical energy for storage and reuse. Under the same operating conditions, it can save 30% to 50% of electric energy consumption compared to trams that do not have the ability to recover. In addition, vehicles use lightweight technologies such as low-floor design and aluminum alloy bodywork. Compared with other slow-charged pure electric buses using lithium batteries, they have an average weight reduction of approximately 1.2 tons. They are equipped with permanent magnet synchronous motors independently developed by CSR. 96% efficiency, low noise, low power consumption, no pollution.
Yang Ying, chief expert of CSR, introduced that the core component of the car, the organic system supercapacitor, is mainly composed of high-performance carbon materials. It has high safety, can be repeatedly charged and discharged more than 1 million times, and is suitable for environmental coverage in all regions of China. For 12 years, it has made up for the lack of safety, poor environmental protection, slow charging speed, low temperature attenuation, and short service life of lithium batteries.
The company side stated that at the CSR Ningbo base, they have pioneered the development of a series of energy-storage (trackless) modern tram products. In terms of vehicles and trolleybus systems, the base has mastered double-layer activated carbon supercapacitors, permanent magnet synchronous motors and efficient braking energy recovery, high-current fast charging, distributed energy storage ground charging, fast intelligent convection current, aluminum alloy The body, safety hedge design, and urban smart transit network interface eight technologies.
