Description

Technical Field

[0001] The present invention relates to the field of charging pile information communication technology, and in particular to a distributed charging pile cluster communication management method. Background Art

[0002] Charging piles are charging equipment that provide charging services for electric vehicles. They are mainly divided into floor-standing charging piles and wall-mounted charging piles. They mainly adopt the charging methods of time, electricity metering and amount metering. Their functions are similar to the gas pumps in gas stations. They are installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. 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 methods, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] At present, the Chinese invention patent with application number 202110864059.5 discloses a communication method and a communication device for a DC charging pile. It can use random numbers to encrypt the communication messages transmitted between the main control chip and the power module in the charging pile, which can effectively prevent the charging pile from replaying the power module. However, the operating environment of the charging pile is complex, and some operating failures often occur, resulting in slow charging or inability to charge.
