バッテリ管理システム : 監視と保護

バッテリモニタおよびプロテクタ

リチウムベースのバッテリパックは、製品の安全性を保証し、使用可能な寿命を延ばすために、正確で堅牢なバッテリ管理ソリューション (BMS) が必要です。MPSは、7~16直列セルバッテリパックの厳しい安全性と精度の要件を満たすために、さまざまなBMSソリューションを提供します。MPSのBMSソリューションは、電圧、電流、および温度を正確にモニタするアナログ・デジタルコンバータ (ADC) を提供します。ADCは、リアルタイムのバッテリパックの動作パフォーマンスと個々のセルの状態の両方に関する重要な洞察を得るためのシステムで使用できます。MPSの製品は、ハイサイド保護ドライバ、電流検知、セルバランス、MCU LDOなど、多くの省スペース回路を統合しています。さらに、MPSのBMS製品をMPSの電池残量計と組み合わせることで、個々のセルの充電状態 (SoC) をモニタして実行時間を最適化するターンキー・バッテリパック設計を実現できます。
