Abstract
A method for controlling a vehicular electric system having multiple power sources including an engine-driven generator. The power sources for supplying power to charge an onboard battery are determined based on difference between the power generation cost of each power source and that for generating an amount of power charged in the battery. Furthermore, amounts power to be supplied to the battery 103 for charge is determined based on the amount of power currently charged in the battery.
Claims26
A method for controlling at least one of vehicular electric systems having a plurality of power sources that supplies power to an onboard electrical load and an onboard battery, comprising:
- obtaining information on power generation costs that are costs of generating unit power by the power sources;
- and
- adjusting at least one of a distribution of power supply of the power sources, a receiving power rate of the onboard electrical loads, and a receiving power rate of the onboard battery in such a manner that a consumed power cost is reduced based on the information.
A method for controlling at least one of vehicular electric systems having a plurality of power sources including an engine-driven generator that supplies power to an onboard electrical load and an onboard battery, comprising:
- obtaining information on power generation costs that are costs of generating unit power by the onboard battery charged by the power sources;
- and
- adjusting discharge of the onboard battery that functions as a power source based on the information.
A method for controlling at least one of vehicular electric systems having a plurality of power sources including an engine-driven generator that supplies power to an onboard electrical load and an onboard battery, comprising:
- obtaining information on power generation costs that are costs of generating unit power by the power sources;
- storing the information in a table for each of a plurality of energy units, each of which indicates unit energy, as information on power generation costs of charging the energy units in the onboard battery;
- deleting the oldest information from the table when discharging the onboard battery by the unit power;
- and
- determining the power generation cost of the onboard battery based on the information on the power generation cost regarding the energy unit currently stored in the table.
