Patent Images
1. A method, comprising:
- determining state data representative of operation and wear of a battery to power a propulsion engine of a vehicle, the state data including an indication of an amount of electrical energy previously supplied from the battery, and/or an estimate of a remaining lifetime of the battery;
authenticating determined state data using encryption; and
transmitting authenticated state data to an on-board computer of the vehicle to display.
