ELECTRICITY STORAGE CONTROL APPARATUS AND METHOD OF CONTROLLING ELETRICITY STORAGE
First Claim
1. An electricity storage control apparatus that controls an electricity storage device mounted on a vehicle, comprising:
- a control device to change a target state of charge, which is used as the target of a state of charge of the electricity storage device; and
a calculating device to calculate an amount of decrease in voltage across the electricity storage device caused as the vehicle is operated,wherein the control device increases the target state of charge if a decreased voltage value, which is lower than a reference voltage value of the electricity storage device by the voltage decrease amount calculated by the calculating device, is equal to or lower than a threshold.

Abstract
An electricity storage control apparatus that controls an electricity storage device mounted on a vehicle includes control device that changes a target state of charge, which is used as the target of a state of charge of the electricity storage device, and calculating device that calculates an amount of decrease in voltage across the electricity storage device caused as the vehicle is operated. The control device increases the target state of charge if a decreased voltage value, which is lower than a reference voltage value of the electricity storage device by the voltage decrease amount calculated by the calculating device, is equal to or lower than a threshold.

9. A method of controlling an electricity storage device that changes a target state of charge, which is used as the target of the electricity storage device mounted on a vehicle, the method comprising:
-
calculating an amount of decrease in voltage across the electricity storage device caused as the vehicle is operated; determining whether a decreased voltage value, which is lower than a reference voltage value of the electricity storage device by the voltage decrease amount calculated, is equal to or lower than a threshold; and increasing the target state of charge if it is determined that the decreased voltage value is equal to or lower than the threshold.
