The invention relates to a block chain based charging
pile charging transaction communication method which overcomes the defects of the prior art. The technical scheme is that: a first step, a charging
pile node generates a charging transaction, and the charging
pile node requests a
timestamp server for
timestamp information; a second step, the charging pile node performs random hashing on charging transaction information, and adds a
timestamp to the charging transaction information and performs block packaging; a third step, the charging pile node having the transaction broadcasts the charging transaction information to the whole network of a charging pile network, and charging pile nodes in the charging pile network update charging transaction block information; a fourth step, a charging pile
transaction service gateway regularly updates block chain information to keep the complete block chain information; a fifth step, the charging pile
transaction service gateway analyzes the changed block chain charging transaction information, and the block chain charging action information is structuralized and stored in a
database; and a sixth step, the charging pile
transaction service gateway determines if the block chain charging transaction information is complete or not, and the fourth step is executed again if not.
