Description
内蔵電源と、
プラス極及びマイナス極の出力を有する出力ポートと、
プラス極及びマイナス極の出力と回路内で接続され、プラス極及びマイナス極の出力間に接続された車両バッテリの存在を検出するように構成された車両バッテリ絶縁(isolation)センサと、
プラス極及びマイナス極の出力と回路内で接続され、プラス極及びマイナス極の出力間に接続された車両バッテリの極性を検出するように構成された逆極性(reverse polarity)センサと、
内蔵電源と出力ポートの間に接続されたパワーFETスイッチと、
車両絶縁センサ及び逆極性センサからの入力信号を受け、パワーFETスイッチに出力信号を提供するように構成されたマイクロコントローラとを含み、
出力ポートにおける車両バッテリの存在と、プラス極及びマイナス極の出力を備えた車両バッテリのプラス及びマイナスのターミナルの正しい極性の接続とを示すセンサからの信号に応答して、内蔵電源を出力ポートに接続するようにパワーFETスイッチがオンにされる。
バッテリセル均等化回路110が図1に示される。バッテリセル均等化回路110は、
公称バッテリ規格12ボルトを有する3つのセルを含むリチウムイオンバッテリ112と、
3つの個々のバッテリセル均等化回路を有するバッテリセル均等化回路114と、
有効・無効を制御する回路116とを含む。
各セルは独立したバッテリセル均等化回路を有し、それらは実質的に同一のものである。
均等化回路を有効化することは、MOSFETスイッチQ2、Q4、Q6をオンにして分圧器抵抗(voltage divider resistors)(R3、R4)、(R13、R14)及び(R23、R24)を電気的に接続することを含み、個々のセル電圧が下げられ、それぞれの比較器(comparator)の反転しない(non-inverting)入力に供給され、それらによる個々のセル電圧の検出が可能となる。均等化回路を無効化することは、MOSFETスイッチQ2、Q4、Q6をオフにして分圧器抵抗(voltage divider resistors)(R3、R4)、(R13、R14)及び(R23、R24)を切り離すことを含み、セル電圧が比較器の反転しない入力に届くことを回避する。それにより比較器の反転しない入力に本質的にゼロボルトが提供され、出力電圧がゼロになり、負荷抵抗R5、R15、R25がセルに接続されることが回避される。
増強モードのMOSFETスイッチQ2、Q4、Q6をオンにすることでバッテリセル均等化回路110が有効となる。それらをオフにすることでバッテリセル均等化回路110が無効となる。スイッチQ2、Q4、Q6は、公称12ボルト制御電圧信号を「Control+」、「Control-」と印されたターミナルの間にかけることによって同時にオンにされる。それらは、公称0ボルト制御信号をかけることにより同時にオフにされる。この実施形態において、制御電圧は、セルが均等化されているバッテリの公称電圧より大きい、もしくは等しい必要がある。、公称12ボルト制御電圧のレベルは、例えば手持ちジャンプスタートユニット内での入手の容易性により選択されており、外部充電ポートを介して、又はリチウムバッテリ112自体からいつでも取得できる。
バッテリセル均等化回路110は、ここで参照され援用される米国特許第9007015号で開示されるバッテリジャンプスタートブーストデバイスに応用又は設置可能である。
