Reasons for the short circuit of the battery plate of the locomotive:
1. Frequently charging and discharging a large current, causing the chemical action of the active material on the electrode plate to be not uniform enough, and the expansion and contraction of the various parts on the electrode plate are not uniform, thereby causing the plate to be bent and broken, the separator being crushed, and the positive and negative phases. bump;
2. The deposit at the bottom of the battery is excessively accumulated, so that the positive and negative electrodes are connected;
3. There are too many impurities in the battery or electrolyte.
