As shown in fig. 1, the present invention provides a transaction system for decommissioning a power battery, including:
the decommissioned power battery processing system is used for uploading the processing information of a decommissioned power battery,
the electronic virtual currency generating system generates electronic virtual currency value information corresponding to the retired power battery according to the processing information of the retired power battery,
the digital shelf system is used for issuing the transaction information of the retired power battery and the retired power battery corresponding to the retired power battery,
and the nodes are used for aggregating at least part of data in the processing information, the electronic virtual currency value information and the transaction information within a preset time and forming a block, forming a block chain by using the block, and sharing the block chain with a plurality of nodes to store the block chain as the distributed ledger.
The processing information comprises the ID, the model, the process information, the production materials, the customer information, the website information and the battery trend data of the retired power battery, wherein the battery trend data comprises the battery capacity and the battery service life.
And the electronic virtual currency generating system generates electronic virtual currency value information corresponding to the retired power battery according to the processing information of the retired power battery, namely pricing the retired power battery.
Due to the fact that specifications and communication ways of different types of batteries are different and technical means of various manufacturers for processing retired power batteries are different, pricing standards of the retired power batteries are difficult to unify, and after the retired power batteries are processed, the retired power batteries can be sold in a separable mode, namely in a single battery mode according to purposes of the retired power batteries; the electronic virtual currency can also be sold in an inseparable form, namely a plurality of batteries are integrated into a system and sold in an integrated form, and the trading situation causes that the single type of electronic virtual currency is difficult to accurately price the retired power battery.
Therefore, by designing different types of electronic virtual currencies, each electronic virtual currency can be used as a value scale to measure the value of at least one retired power battery.
The category of electronic virtual currency may be of the homogeneous currency type, which is divisible, which is where the value on the transaction output may be subdivided into smaller amounts that may be distributed among a plurality of new electronic virtual currencies. Examples of divisible electronic virtual currency include electronic virtual currency for legal currency or electronic virtual currency for shares in a horse race. A separable contract may be defined as a contract that specifies a non-zero hooking rate. In other words, the electronic virtual monetary value is associated with the underlying electronic virtual monetary value.
The kind of electronic virtual money may also be a non-homogeneous currency type, which is indivisible, which is a contract that specifies the holder's rights according to a fixed value, for example, a contract to redeem a house or a contract of 1000 australia dollars (AU $). Because of the inseparability, they can only be transferred as a whole.
In view of the divisible or inseparable characteristic of the electronic virtual currency, the invention designs different types of electronic virtual currencies to measure the value of retired power batteries.
