What are the reasons for the slow start of lithium battery electric locomotives?

After the lithium battery electric locomotive has been used for a long time, sometimes it will start very slowly, or even fail to start. What are the reasons for these problems?

First, you can check whether there is too much oil on the surface of the wheels or tracks, resulting in insufficient adhesion coefficient, which makes the lithium battery electric locomotive slip. If yes, clean it up.

If it is not the oil pollution problem, then the problem probably lies in the motor or battery.

If the battery has been used for several years, you can check the battery first. Of course, if the battery casing has obvious problems or even smokes, or smells burnt rubber. The high probability is that there is something wrong with the battery. You can check the battery directly, and then check the wheels, track surface and motor after the battery is processed. The treatment method depends on the problem of the battery. Poor contact, damaged parts, etc. can be replaced and installed; if you need professional maintenance personnel, you can contact the manufacturer; if the working life of the battery is over, it is recommended that you consider changing a battery.

Then there's the matter of the motor. For example, a dual-motor lithium battery electric locomotive should be powered by two traction motors. If one of them "strikes" due to poor contact or other reasons, and the remaining motor does the work of the two motors, it will obviously start slowly. It may also be that there are some problems inside the motor, resulting in a reduction in the output power of the motor. If so, it is recommended to contact the manufacturer for repair.

In the end, it may also be that the transmission part is severely worn, resulting in a reduction in transmission efficiency. In this case, the transmission part may fail directly at any time.
