Description

Technical Field

[0001] This specification relates to the field of new energy vehicle technology, and in particular to a charging pile cooling device, a vehicle-end charging cooling device, a vehicle-charging pile integrated charging cooling system, and a new energy commercial vehicle. Background Technology

[0002] In recent years, the development of charging piles has been rapid, and charging power has gradually increased. Superchargers typically have a charging power of over 250kW, with some even reaching a peak power of 800kW. However, this increase in charging power has also led to a sharp increase in heat generation from new energy vehicles during the charging process.

[0003] Compared to passenger vehicles, new energy commercial vehicles have longer charging times due to their larger battery packs. This causes heat to gradually accumulate during prolonged charging, eventually leading to overheating and current limiting in the battery and / or charging station. Ultimately, this reduces the charging rate, increases charging waiting time, lowers the operating efficiency of a single vehicle, and increases the payback period per vehicle. Utility Model Content
