CHARGING/DISCHARGING CONTROL APPARATUS
First Claim
1. A charging/discharging control apparatus for controlling charging/discharging of a battery in a vehicle having a first motor connected to an internal combustion engine to start the internal combustion engine and driven by the internal combustion engine to generate power, a battery for storing the power from the first motor, and a second motor connected to the drive wheels to drive the drive wheels with the power from the first motor or the battery and to generate a braking force at the drive wheels for regenerative power generation,the charging/discharging control unit comprising:
- a temperature detecting unit for detecting a temperature of the battery;
an SOC detecting unit for detecting a State Of Charge of the battery;
a storage unit for storing a first map in which a battery temperature and a target SOC for enabling the regenerative power generation at the battery temperature are associated with each other, and a second map in which the battery temperature and a target SOC for enabling startup of the internal combustion engine at the battery temperature are associated with each other; and
a charging/discharging control unit for acquiring the target SOC associated with the battery temperature detected by the temperature detecting unit based on the first map or the second map, and for controlling charging/discharging so that the SOC detected by the SOC detecting unit matches the acquired target SOC.

Abstract
A hybrid electric vehicle 1 has a battery state detecting unit for detecting a temperature and SOC of a battery pack, a storage unit for storing a first target SOC calculation map in which a battery temperature and a target SOC which enables regenerative power generation at that battery temperature are associated with each other, and a second target SOC calculation map in which a battery temperature and a target SOC which enables startup of an internal combustion engine at that battery temperature are associated with each other, and a charging/discharging control unit for acquiring a target SOC which corresponds to the detected battery temperature based on the first target SOC calculation map or the second target SOC calculation map to control charging/discharging so that the detected SOC matches the acquired target SOC.
