Method used for charging-pile fee rate storage

The invention relates to the field of data storage of charging piles, and discloses a method used for charging-pile fee rate storage. The method includes: step 1, detecting charging fee rate data, which are stored by a charging pile, at a time interval equal to a first preset time; step 2, opening up a memory for caching in a case of determining failure of continuous storage fail according to a detection result; and step 3, periodically storing cached data at a time interval equal to a second preset time interval. According to the method used for charging-pile fee rate storage, the problem that charging piles are liable to invalidation of continuous fee rate storage in the prior art is overcome, and correctly storing charging-pile charging price information is realized. 本发明涉及充电桩的数据存储领域，公开用于充电桩费率存储的方法，该方法包括：步骤1，每隔第预设时间对充电桩存储的充电费率数据进行检测；步骤2，根据检测结果，在判定连续存储失败的情况下，开辟内存进行缓存；步骤3，每隔第二预设时间间隔定时将缓存的数据进行存储。该用于充电桩费率存储的方法克服了现有技术中的充电桩容易出现费率连续存储失效的问题，实现了正确存储桩充电价格信息。
