BATTERY MANAGING DEVICE AND BATTERY MANAGING METHOD
First Claim
1. A battery managing device comprising:
- a first deriver that derives a provisional value indicating a charge state of a battery provided to a vehicle including an electric motor as a drive source;
a second deriver that derives the charge state of the battery based on a condition obtained by comparing the provisional value and a boundary point between a plurality of ranges divided in accordance with an available charged amount of the battery;
a determiner that determines to which of the ranges the battery belongs based on the charge state of the battery derived by the second deriver; and
an instructor that instructs a control on charging and discharging of the battery in accordance with the region determined by the determiner, whereinthe boundary point is set based on a minimum required available charged amount for the battery belonging to at least one specific range of the ranges, andthe minimum required available charged amount is an available capacity of the battery in a predetermined degradation state belonging to the specific range.

Abstract
A battery managing device includes a first calculator, a second calculator, a determiner, and a controller. The first calculator calculates a provisional value indicating a charge state of a battery provided in a vehicle including an electric motor as a drive source. The second calculator calculates the charge state of the battery based on a condition obtained by comparing the provisional value and a boundary point which is on a boundary between a plurality of regions divided in accordance with an available charged amount of the battery. The boundary point is determined based on the available charged amount of the battery in a predetermined degradation state. The determiner determines in which region among the regions the charge state of the battery locates. The controller controls to charge and discharge the battery in accordance with the region determined by the determiner.
