Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile operating panel capable of dissipating heat. Background Art

[0002] Charging pile is a kind of energy replenishment device that provides power for electric vehicles. Its function is similar to the gas pump in the gas station. It can be fixed on the ground or wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the voltage and current adjustment. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] The existing charging pile operation panel is not provided with a heat dissipation function. The heat generated by the internal electronic components of the operation panel accumulates in the charging pile operation panel, causing the operation panel to be slow to respond to card charging and frequent faults such as damage to the control circuit board when in use. There is an urgent need for a charging pile operation panel that can dissipate heat. Utility Model Content
