Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery electric locomotives, in particular to a lithium battery electric locomotive. BACKGROUND

[0002] The lithium battery electric locomotive is an electric locomotive with lithium batteries as power sources, which has many advantages and characteristics. The working principle of the lithium battery electric locomotive is based on the charging and discharging characteristics of lithium batteries and the electromagnetic induction principle of electric machines. When the lithium battery electric locomotive is charging, the external power source inputs electric energy into the lithium battery pack, so that a chemical reaction occurs inside the battery to store electric energy. In the running process, the lithium battery pack outputs the stored electric energy to the electric machine, and the coil inside the electric machine rotates under the action of electromagnetic force in the magnetic field, thereby driving the wheels to rotate, making the electric locomotive move forward or backward. When it is necessary to stop, the braking system stops the rotation of the wheels through mechanical or electrical means.

The lithium battery electric locomotive has the beneficial effects that the overall traction is adopted to evenly distribute the traction force to two core discs to share, effectively relieving and avoiding the situation that a single core disc is overloaded, ensuring the service life of the core disc and the safety of the locomotive traction. During the parking of the locomotive on a slope, the traction force will not act on the core disc, ensuring the safety of parking.
