Battery-powered electric locomotives are powered by rechargeable batteries. Battery charging typically occurs in the underground electric locomotive garage. Once the battery pack on the locomotive has been used to a certain extent, 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, ideal for small-scale transportation systems and tunneling operations with irregular tunnels.

Drawbacks: Requires charging equipment; high initial investment; low energy efficiency; high transportation costs.
