Charging piles belong to typical high-frequency non-linear loads: frequent plug-in start-up, full-charge shutdown and dynamic-power adjustment produce large transient-current shocks; high-frequency rectification-and-inversion of charging modules generate rich harmonics; concurrent charging of multiple piles brings harmonic superposition and grid-voltage fluctuation; outdoor-installed piles are exposed to sunshine, rain, wide-temperature swings and dust, creating harsh operating environments. General-purpose industrial transformers and reactors cannot satisfy requirements of heavy-power-shock, frequent-start-stop and outdoor-weather-resistance for charging-pile applications. Long-term operation leads to overheating-induced magnetic-saturation, insulation aging and disabled protection. Consequences include frequent tripping of […]
