SCiB is utilized as a battery for storing energy regenerated from trains, and also as an emergency battery for supplying electric power to permit evacuation operation if the power supply is cut off. The battery system is utilized for the hybrid rolling stocks to reduce the total energy consumption of the rolling stock system compared to conventional systems.
As for the hybrid locomotive design, the only practical auxiliary storage units available today are electrochemical batteries, including lead-acid, Ni-Mh, and Li-ion ones [17, 18]. Due to the limited wheel traction of locomotives operating at low speeds, there are no potential performance benefits from the increased traction effort of the hybrid
