- 複数の電池セルをまとめたモジュールが複数個配置された電源部を備える電気自動車の電源管理装置であって、
各モジュールに搭載され、各モジュールの電圧と温度を検知するモジュール状態検出手段と、
各モジュール状態検出手段によって検出された情報を基に、各モジュールの状態を判定する制御手段とを備え、
各モジュール状態検出手段は、付番通信線を介して直列に接続され、接続上流のモジュール状態検出手段から送信されたID情報を基にして、前回の付番ID情報と今回の付番ID情報とを比較して自身に識別番号を付与し、その識別番号を含むID情報を接続下流のモジュール状態検出手段に送信する機能を有するとともに、自身に付与した識別番号を自身が備える記憶部に書込み、その書込みが正常に終了したか否かを判定し、正常の場合には、自身のID情報に付番ID情報が正常に付与されたことを示す情報を含めて送信し、書込みが正常でない場合には、自身のID情報に付番IDが情報正常に付与されなかったことを示す情報を含めて送信し、
前記制御手段は、前記各モジュール状態検出手段と前記付番通信線及び通信線で接続され、前記付番通信線及び通信線を介して送信された検出情報に基づき、前記各モジュールの異常をモジュール毎に特定することを特徴とする電気自動車の電源管理装置。 - 各モジュール状態検出手段は、前回の付番ID情報と今回の付番ID情報と比較し、前回と今回の付番ID情報が変更なく同一の場合には、前回の付番ID情報を維持し、
前回の付番ID情報がなく、今回がそのモジュールにとって始めての付番の場合には、今回の付番ID情報を自身の付番ID情報と決定し、その付番ID情報を前記記憶部に書込み、
前回の付番ID情報と今回の付番ID情報とが異なる場合には、今回の付番ID情報を自身の付番ID情報と決定し、その付番ID情報を前記記憶部に書込むことを特徴とする請求項1に記載の電気自動車の電源管理装置。 - 前記各モジュール状態検出手段と前記制御手段とは、付番通信線を介してリング状に接続されることを特徴とする請求項1または2記載の電気自動車の電源管理装置。
