Ultra Capacitor Brings New Choices for The Future of Mobility

The concept of next-generation transportation ecosystem, the future of mobility, is reshaping the landscape of transportation industry. Auto makers are scrambling to invest in the autonomous, connected and shared business: system makers are working hard to achieve complete electrification on the cars, battery and ultracapacitor manufacturers are taking advantage of this opportunity to seek long-term development. In September, the International Rail Transportation Technology Exhibition is going to be held in Berlin of Germany, which is themed on “The Future of Mobility”and has attracted more than a thousand enterprises worldwide. China’s leading manufacturer of ultracapacitor–Supreme Power Solutions Co. Ltd.(SPS) will jointly participate this event with its German partner and present diversified ultracapacitor solutions then.

Supercapacitor, with the characteristics of long cycling life, high power, rapid charging/discharging ability, can provide energy storage units of braking energy recovery, start-stop auxiliary power and traction power supply for various types of new energy vehicles such as Hybrid electric vehicle(HEV, Plug-in hybrid electric vehicle (PHEV) ,dual-source trolleybus, fuel cell buses and school buses, etc. It can also effectively improve the dynamic characteristics of passenger cars during starting, accelerating and ascending, efficiently recover braking energy , and ensure passenger cars to start up smoothly under low temperature or battery failure.

As both the level and number of electronic equipment on automobiles are improving, the voltage of power supply also has a trend to increase, which requires higher reliability and instant power supply of on-board power supply system. Ultracapacitor module/package or battery/capacitor composite power supply can meet vehicle’s demand for braking energy recovery, auxiliary power, start-stop system, short-term backup power and peak-hour power supply. It can provide energy storage for electrical suspension, electric power steering, electric turbocharging, and energy recovery, and can also be used as an backup power for autonomous driving and advanced driver assistance systems (ADAS).

The specially-designed capacitor module for heavy trucks can be used to start the vehicle immediately when lead-acid battery runs out or  weakens, to avoid any delay and cost increase caused by cross-line start-up and idling operation of the vehicles, so as to reduce the vehicle’s operating expenses.

In the field of rail transit: the 100% low-floor tram with ultracapacitor as its power storage and traction power supply, is suitable for the frequent start and stop of urban rail transit and the energy can be recycled to save cost.The auxiliary starting system on the diesel locomotive with super capacitor as its main energy storage , is fit for the environment of frequent starting , low temperature starting,  and can effectively reduce idling operation, save fuel and protect the environment. On subway, the ultra capacitor energy storage device can recover and store the direct current (dc)  at the braking, then provide power supply at starting to reduce energy conversion, and will release the energy stored previously during the traction operation to the catenary, in order to stabilize the votage on the catenary, reduce the output power of the traction station at peak hours, and to avoid impact of renewable energy on the power grid.

About New Energy Vehicle

On August 10, 2012, the world’s first supercapacitor light rail train was produced in Zhuzhou,Hunan province. The new electrical train can carry up to 320 people, without high-voltage power lines along its way and can be quickly recharged after a 30-second stop. After charging, the train can travel at high speed towards the next station 2 kilometers away, and then get passengers on and off whiling charging, so on and on.

On December 6, 2016, the tram subsidiary of CRRC in Zhejiang has designed and produced a trolley for the City of Graz in Austria, which is  18-meters long with ultra-capacitor power supply (two trolleys in total). The new trolley started its first testing operation at 34E, a 3.5-km test line. With a capacity of 135 people, the tram uses 60000 farad supercapacitors as its main power and adopts quick charging pattern. Quick charging stations are set up at one end and the middle of the testing line, and l-type charging piles are built. When the vehicle arrives at the station, it will be automatically raised by the electric bow, and the charging process will be completed within 30 seconds when the passenger are getting on and off the bus. This trolley can operate continuously in 24-hours.
