Title:
電気自動車用ハイブリッドバッテリシステム
Document Type and Number:
Japanese Patent JP5818048
Kind Code:
B2
Abstract:
A hybrid battery system for an electric vehicle includes a lithium battery module including a plurality of lithium battery cells, a lead storage battery module including a plurality of lead storage battery cells, a first sensing unit including a sensor for measuring a temperature and a voltage of the lithium battery module, a second sensing unit including a sensor for measuring a temperature and a voltage of the lead storage battery module, a control circuit connected to the first sensing unit and the second sensing unit, the control circuit configured to measure a state of charge of each of the lithium battery module and the lead storage battery module by using the temperature and the voltage measured in the first sensing unit and the second sensing unit and to generate a control signal by comparing the temperature of the lithium battery module with a reference temperature and comparing the voltage of the lead storage battery module with a reference voltage, and a charging/discharging circuit connected to the lithium battery module and the lead storage battery module, the charging/discharging circuit including a switch for selectively discharging the lithium battery module or the lead storage battery module in response to the control signal.
