バッテリーモニタリングと保護

バッテリーモニタリングと保護

リチウムイオンをベースとしたバッテリーパックは、安全性を確保し、製品寿命を引き延ばすため、安全性と正確で堅牢なバッテリーマネジメント・ソリューション (BMS) を必要とします。MPSは7から16の並列バッテリーパック用に、安全性と制度の要求に見合う幅広いBMSソリューションを提供しています。MPSのBMSソリューションは、精密に電圧、電流、温度をモニタリングするA/Dコンバータとして提供され、リアルタイムのバッテリーパックの駆動パフォーマンスおよび各セルの状態について役立つ分析を得るためにシステム内で使用されます。MPSの製品ハイサイド保護ドライバ、電流センサ、セルバランシング、およびMCU LDOのような、多くの機能を内蔵しており省スペース化が可能です。さらに、MPSのBMS製品はMPSの電池残量計ICと併用することができ、個々のセルの充電率 (SoC) モニタリングでランタイムを最適化するためのターンキーのバッテリーパック設計を達成できます。
