Title:
CHARGE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2022139797
Kind Code:
A
Abstract:
To suppress deterioration of a battery and to correspond to a wide variety of charging devices.SOLUTION: A charge control system includes a storage device capable of storing a charge current ratio as a ratio of charge current to charge a battery with respect to the maximum charge current allowed for the battery for a first hour. The charge control system calculates the charge current ratio every second hour, which is shorter than the first hour, using the maximum charge current set based on the battery storage ratio and the battery temperature, and replaces the calculated charge current ratio with the oldest charge current ratio among the charge current ratios stored in the storage device. The charge control system prohibits the charging of the battery by the charging device when the sum of the charging current ratio stored in the storage device is a predetermined value or greater.SELECTED DRAWING: Figure 2
