Battery-powered rail vehicle
Battery-powered electric locomotives are powered by batteries. Battery charging typically occurs in the underground locomotive garage. Once the battery pack on the locomotive reaches a certain level, it is removed and replaced with a fully charged one. Therefore, each locomotive must be equipped with 2-3 battery packs.
Advantages: No spark ignition hazard, suitable for use in mines with gas; no need for wiring, flexible usage, highly applicable for small-scale transportation systems and tunneling operations with irregular tunnels.
Drawbacks: Requires charging equipment; High initial investment; Low energy efficiency; High transportation costs.
