Abstract
A vehicle running management system under renewable energy includes an electrically driven vehicle having a battery ECU. The battery ECU manages a remaining amount of renewable energy in a vehicle-mounted electric storage device as it increases and decreases when renewable energy is charged into the vehicle-mounted electric storage device and renewable energy is discharged from the vehicle-mounted electric storage device.
Claims16
A vehicle running management system under renewable energy comprising:
- a charging site, having an electric generator, which is supplied with renewable energy from the electric generator and system energy from a system energy source;
- a charging site manager for managing an amount of renewable energy in the charging site;
- an electrically driven vehicle having a vehicle-mounted electric storage device which is charged with renewable energy and system energy that are sent from the charging site when the vehicle-mounted electric storage device is electrically connected to the charging site;
- and
- a vehicle manager for managing an amount of renewable energy stored in the vehicle-mounted electric storage device of the electrically driven vehicle;
- wherein the vehicle manager manages a remaining amount of renewable energy stored in the vehicle-mounted electric storage device as the remaining amount increases and decreases when renewable energy is charged into the vehicle-mounted electric storage device and renewable energy is discharged from the vehicle-mounted electric storage device, and
- wherein the vehicle manager further manages a remaining amount of system energy stored in the vehicle-mounted electric storage device and a total remaining amount of energy stored in the vehicle-mounted electric storage device,
- wherein the vehicle manager calculates a loss as a difference between a total discharged amount representing a total transmitted amount of electric energy, which includes renewable energy and system energy measured at the charging site, and a total charged amount in the vehicle-mounted electric storage device which is measured by the vehicle manager, and
- if the loss is smaller than the amount of system energy transmitted from the charging site, then the vehicle manager manages the loss entirely as an amount of system energy, and if the loss is greater than the amount of system energy transmitted from the charging site, then the vehicle manager covers the loss with the amount of system energy and manages a shortage of the amount of system energy as the amount of renewable energy.

- wherein the vehicle manager is configured to select whether electric energy required to drive the electrically driven vehicle should be the renewable energy or the system energy;
- and
- when regenerated electric energy is charged into the vehicle-mounted electric storage device while the electrically driven vehicle is running, the vehicle manager manages an increase in the electric energy which is caused by the regenerated electric energy as an increase in renewable energy.
