Title:
AUXILIARY BATTERY SYSTEM
Document Type and Number:
Japanese Patent JP2014217194
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase a cruising range of a movable body by charging a secondary battery with surplus power of an auxiliary battery while charging a main battery from the auxiliary battery, and avoid a substantial increase in weight.SOLUTION: An auxiliary battery system includes a main battery 10, a secondary battery 15 for charging the main battery 10, an auxiliary battery 20 for charging the main battery 10 or the secondary battery 15, and a path switching part 30 for switching between a charging path (a) from the auxiliary battery 20 to the main battery 10 and a charging path (b) from the auxiliary battery 20 to the secondary battery 15, and is used by being mounted on a movable body. The auxiliary battery system also includes switching determination means C1 for determining whether or not to switch the charging from the auxiliary battery 20 to the main battery 10 to the charging from the auxiliary battery 20 to the secondary battery 15 based on charging path switching information for switching the charging paths (a) and (b), and charging path switching means C2 for switching the charging paths (a) and (b) through the path switching part 30 when it is determined that the path is to be switched from the charging path (a) to the charging path (b).
