Aowei ultracapacitor technology has application for trams

Ultracapacitors store energy and electrify different types of vehicles. Unlike lithium batteries, they are better suited for heavy-duty applications since they are recognized for their robustness, safety, long service life, and resistance to temperature fluctuations.

Aowei’s Ultracapacitors are energy storage technology that offers high power density, almost instant charging and discharging, high reliability, extreme temperature tolerance, and a lifespan of 1,000,000 charge-discharge cycles.

The ultracapacitors series of high-energy organic hybrid ultracapacitors produced by Aowei is a cutting-edge energy storage technology that enables modern trams to operate without overhead supply cabling. This leads to a reduction in the cost of infrastructure and businesswise is a more profitable solution for public transport operators.

There are three types of tram operation modes with UC offered to the operators:

Full-line Catenary-free

0~100% State-Of-Charge method for fully charged of ultracapacitor from 3 to 4 minutes.
Ultracapacitor lifespan is 1 million cycles/ 10 calendar years.
Partial line catenary-free

Charging method is onboarding high power DC/DC charging.
Ultracapacitor lifespan is 1 million cycles/ 10 calendar years.
Cross-section catenary-free

Charging method is onboarding high power DC/DC charging.
Ultracapacitor lifespan is 1 million cycles/ 10 calendar years.

The key benefits of UC technology for trams are:

Huge reduction in infrastructure investment – catenary and lines;
Ability to work with smaller grid capacity, (as compared to catenary trams) as increasing grid capacity is a huge cost;
Providing flexibility and higher availability for tram operation;
Visual impact reduction in city centers due to the catenary removal.
