Embodiment

[0063] The method for evaluating the battery life of an electric vehicle based on a block chain and a charging device provided by the present invention includes:

[0074] Step 6.2: The block chain service platform authorizes the request with the download permission, and charges all the

[0075] Step 6.3: All charging operation platform servers in the alliance retrieve whether there is a

[0076] Step 6.4: The authorized charging pile obtains the data in each charging section in the entire charging network by means of subscription.

[0077] Step 6.5: The above-mentioned hash value and the hash value first uploaded to the blockchain service platform are checked one by one to confirm that

[0078] Step 6.6: After the charging pile obtains the complete charging data, according to the sequence of the time stamps,

[0081] R=(SUM_VI‑SUM_V*SUM_I / Sample_num) / (SUM_II‑SUM_I*SUM_I / Sample_num)

[0085] Step 7.4: Define the ratio of the first limit power and the second limit power as the curren...

Abstract

The present invention provides a battery life evaluation method and system for electric vehicles based on blockchain and charging equipment, including: step 1: integrating edge computing equipment equipped with blockchain technology into the charging pile side, and building a charging alliance network; 2: Obtain the single charging data of the electric vehicle; Step 3: Filter the obtained single charging data; Step 4: Repeat Step 2 and Step 3 to obtain the charging data of any charging pile of the electric vehicle in the charging alliance network ;Step 5: Stitch all the charging data of the electric vehicle; Step 6: Build a battery life assessment model; Step 7: Import the stitched charging data into the battery life assessment model for estimation, and obtain the battery health at the current moment Status SOH. The present invention utilizes the characteristics of the distributed storage of the block chain to solve the problem of fragmentation and fragmentation of the charging data on the charging pile side, and effectively estimates the battery life on the charging pile side.

Description

Electric vehicle battery life assessment method and system based on blockchain and charging equipment technical field The present invention relates to the technical field of block chain, in particular, to a kind of electric vehicle based on block chain and charging equipment Battery life assessment method and system. Background technique [0002] In the whole life cycle of the battery of a pure electric vehicle, it will be charged on different charging platforms of different charging pile enterprises. Charge on the charging pile. Therefore, the charging data is fragmented, and it is impossible to obtain a complete charging through a certain charging pile or charging platform. data; and fragmented data is useless and cannot be used for battery life assessment. The present invention proposes the use of blockchain The technology stitches the split charging data, obtains the complete charging data of pure electric vehicles, and uses these data to build The battery lif...
