Power control system for e.g. automobile, has controller and DC/DC converter transferring power between two supply lines when specific condition based on one of capacitor energy value and generation capacity margin is satisfied

摘要

The system has a calculation unit calculating a margin up to a maximum generation capacity of a main generator based on factors comprising an energy consumption value of electrical devices and an admissible power generation value of the generator. A controller and a DC/DC converter (31, 32) transfer power between two supply lines when a specific condition based on one of capacitor energy value and the margin is satisfied. An independent claim is also included for a method for controlling power in a vehicle.
