3.Cause of accident

The transformer in the charger is prone to insulation failure. When this happens, a partial short circuit occurs between windings, causing a momentary over-current. Although the fusing resistor, installed as a safety device, is melted by the over-current, improper materials covering the fuse periphery are carbonized by the heat and become conductive. Consequently, excess current continues to flow, causing the fusing component to overheat and eventually produce smoke and fire.
