Abstract
A battery data management method for use in a battery data management system including an electric vehicle and a plurality of authentication servers each including a distributed ledger includes: obtaining, by the electric vehicle, first sensor information about a battery attached to the electric vehicle; generating, by the electric vehicle, first transaction data including the ID of the battery and the first sensor information; obtaining the first transaction data by one authentication server included in the plurality of authentication servers; and recording a block including the first transaction data into the distributed ledger by the one authentication server.
Claims15
A battery data management method for use in a battery data management system including an electric vehicle and a plurality of authentication servers each including a distributed ledger, the battery data management method comprising:
- obtaining, by the electric vehicle, first sensor information about a battery attached to the electric vehicle;
- generating, by the electric vehicle, first transaction data including an ID of the battery and the first sensor information;
- obtaining the first transaction data by one authentication server included in the plurality of authentication servers;
- and
- recording a block including the first transaction data into the distributed ledger by the one authentication server, the block including a chain consisting of a hash value of a previous block in the distributed ledger, and the distributed ledger being synchronized between the plurality of authentication servers.
A non-transitory computer-readable recording medium having recorded thereon a program causing a computer to execute a battery data management method for use in a battery data management system including an electric vehicle and a plurality of authentication servers each including a distributed ledger, the program causing the computer to execute:
- obtaining, by the electric vehicle, first sensor information about a battery attached to the electric vehicle;
- generating, by the electric vehicle, first transaction data including an ID of the battery and the first sensor information;
- obtaining the first transaction data by one authentication server included in the plurality of authentication servers;
- and
- recording a block including the first transaction data into the distributed ledger by the one authentication server, the block including a chain consisting of a hash value of a previous block in the distributed ledger, and the distributed ledger being synchronized between the plurality of authentication servers.
A battery data management system comprising:
- a plurality of authentication servers each including a distributed ledger;
- and
- an electric vehicle, wherein
- the electric vehicle includes:
- a first communicator that obtains first sensor information about a battery attached to the electric vehicle;
- and
- a transaction data generator that generates first transaction data including an ID of the battery and the first sensor information, and
- one authentication server included in the plurality of authentication servers includes:
- a second communicator that obtains the first transaction data;
- and
- a recorder that records a block including the first transaction data into the distributed ledger, the block including a chain consisting of a hash value of a previous block in the distributed ledger, and the distributed ledger being synchronized between the plurality of authentication servers.
