In step S205, the network device updates the local blockchain according to the received blockchain.
Specifically, in step S201, the network device (monitoring platform) is connected to the control systems of the multiple vehicles via the network, so as to obtain the operation data of the vehicles in real time, the network device needs to perform the privacy elimination process and the desensitization process on the collected operation data of the vehicles, and the operation data after the privacy elimination process and the desensitization process can be opened to the public, that is, any node of the network can download the operation data of the vehicles in the network device via the network. For example, the operating data of the vehicle may include: the vehicle state, the charging state, the operation mode, the vehicle speed, the accumulated mileage, the total voltage, the total current, the SOC, the DC-DC state, the gear position, the insulation resistance, the highest value of the cell voltage, the lowest value of the cell voltage, the highest value of the cell temperature, the lowest value of the cell temperature, the high-temperature alarm of the battery, the overvoltage alarm of the battery, the undervoltage alarm of the battery, the low alarm of the SOC, the overvoltage alarm of the cell, the undervoltage alarm of the cell, the overhigh alarm of the SOC, the jump alarm of the SOC, the temperature difference alarm, the poor consistency alarm of the cell, the insulation alarm and the like, and the format and the meaning of the operation data of the vehicle can refer to the technical specification of GBT32960.3-2016 electric vehicle remote service and management system (part 3.

In step 202, the network device obtains a composite estimated error for each generating device for the test vehicle based on the estimated remaining useful life and the estimated remaining energy in response to billing requests issued by the plurality of generating devices. Step S202 specifically includes step S301, step S302, and step S303.
Fig. 3 is a schematic diagram of a process for obtaining the integrated estimation error.

The integrated estimation error (0.3 × 7.5% +0.7 × 3.17%) of the generating device is 4.47% as can be obtained by the above formula of the integrated estimation error.
In step S203, the network device sends an accounting grant to the generating device with the smallest aggregate estimation error, that is, the generating device with the smallest aggregate estimation error in the plurality of generating devices sending the accounting request obtains accounting rights, and the generating device obtaining accounting rights can generate a new block and add the new block to the end of the existing block chain of the vehicle to form a new block chain.
In step S204, the network device receives the block of the current time of each vehicle of the same model as the test vehicle generated by the generation device that obtained the accounting license and adds the block to the block chain corresponding to the vehicle. The generating device obtaining the accounting license obtains the accounting right for the blockchain of each vehicle with the same model as the test vehicle, namely, a new blockchain is generated according to the operation data of each vehicle and added to the corresponding blockchain.

The battery information of the vehicle is obtained by the generation device according to a preset estimation model which takes the running data of the vehicle as input and takes the battery information of the vehicle as output, namely, the residual service life of the battery and the residual energy of the battery are output. In step S403, the generation device that obtains the accounting license generates a block of the current time of each vehicle from the battery information and the operation data, and adds the block to the end of the block chain associated with the vehicle, the block including the hash value of the previous block and the hash value of the present block.
