CHARGING SYSTEM FOR MINIMIZING SYSTEM ENERGY
First Claim
Patent Images
1. A charging system for minimizing system energy comprising:
- an electrically driven vehicle including a vehicle-mounted electric storage device, which is charged with and retains renewable energy and system energy, and a vehicle-mounted charging controller for controlling charging of the vehicle-mounted electric storage device; and
a charging site including a generating device for generating the renewable energy, a charging site electric storage device for storing the renewable energy and the system energy, and a charging-site charging controller for controlling storage of energy in the charging site electric storage device, and also controlling a type of energy used for charging the vehicle-mounted electric storage device of the electrically driven vehicle from the charging site,wherein the vehicle-mounted charging controller and the charging-site charging controller cooperate to charge the vehicle-mounted electric storage device of the electrically driven vehicle with a necessary amount of energy, which corresponds to an amount of energy consumption in a next-time running of the electrically driven vehicle, such that a shortage of the renewable energy is compensated for by charging with the system energy.

Abstract
A vehicle-mounted electric storage device of an electrically driven vehicle is charged with a necessary amount of energy, which corresponds to an amount of energy consumption in a next-time running of the electrically driven vehicle, such that a shortage of renewable energy at a charging site is compensated for by charging the electrically driven vehicle with system energy.
