New trolleys can fully recharge in 30 seconds

Train equipment maker CRRC Corp is introducing a fast-charge trolley bus system that trades traditional overhead cables for an energy model that can fully charge a trolley in 30 seconds while passengers are getting on and off.

The company claims that the flash charge supercapacitor is the only one in the world that allows a trolley bus to run for 8 kilometers with 10 seconds of charging.

"The technology is especially suited for buses that make frequent stops over short distances, and greatly reduces the pollution from public transportation," said Zhou Qinghe, the president and general manager of CSR Zhuzhou Electric Locomotive Co.
