Electric vehicle energy balance-sheet credit and debit system and procedures

摘要

The invention concerns a safe and verifiable measurement and data logging system with a measurement and data logging device on board a vehicle, the measurement and data logging device being a performance measurement or other device capable of: reliably and accurately measure the size and direction of the energy flow between the vehicle energy input and the energy storage unit, an Ethernet network,CAN,Flexray,Bluetooth or other data transmission connection to other devices in the vehicle, a central processing unit with a durable storage unit, a connectivity module enabling connection to the Internet; and a decentralised and cryptographically secure database, where the database allows specific data access to mathematical algorithms that perform previously agreed transactions and allows the measurement and data acquisition device to access and write encrypted data into the database, when a suitable safety key is provided by the device and has the ability to:reliably prevent the Border Energy Storage from being charged.
