Battery-powered tramways are a type of public transportation system that rely on batteries for power. New projects in this field often focus on lithium-ion (Li-ion) batteries, which is a family of electrochemistries that has developed over the last 30 years. One relatively new type of Li-ion battery is Lithium Titanate Oxide (LTO).
The tram is running forward and backward on the rail line in the testing periods. Operation Mode Switching (OPMS) method. The tram is mainly manually operated based on a control screen, shown in Fig.5 (b). For safety in the test period, the LB and UC are only working in discharging mode when the tram is running.
