AI Technical Summary

Problems solved by technology

However, since there are a lot of controls to be performed, such as driving the car or coordinating equipment, the power consumption of the main CPU is generally large, for example, about 50W.
Therefore, most of the power generated by power generation using natural energy will be consumed by the main CPU, and the charging efficiency will be significantly lower.

Abstract

A vehicle driving device is arranged such that in accordance with an instruction signal from the outside, a first battery managing section outputs, to the outside, a signal related to charging / discharging control for a first battery.

Description

technical field [0001] The present invention relates to vehicles such as automobiles and electric trains, and more specifically, to a vehicle driving device equipped with a traveling motor and a battery for driving the traveling motor. A vehicle charging system that charges the battery. Background technique [0002] In recent years, from the viewpoint of solving energy-related problems, the use of natural energy such as wind power generation and solar power generation has become popular. [0003] On the other hand, from the viewpoint of solving problems related to the environment, electric vehicles and electric motorcycles are more likely to be widely used. [0004] From these viewpoints, attempts to mount photovoltaic power generation panels on electric vehicles and use energy generated by the photovoltaic power generation panels in electric vehicles are being put into practical use. [0005] FIG. 13 is a system configuration diagram of a conventional vehicle air conditio...
