概览
BMS 是每块锂离子电池的重要组成部分。它提供过流、过热和过压等故障保护,确保安全运行。MOSFET、栅极驱动器、MCU 和集成电路等组件相互作用,通过估计 SOC(充电状态)和 SOH(健康状态)向用户传送重要的电池数据。
产品优势
- 精确的电压测量
- OptiMOS™提供可靠的保护
- 具有高级功能的 MCU
- 具有保护功能的栅极驱动器

关于
电动工具、无人机、电动自行车和电动两轮车是目前非常流行的消费电子设备。这些设备需要高电流能力,因此,新型锂离子电池开始占据主导地位。
通过这些新的解决方案,电动工具的性能既得到加强,又不失灵巧。重要的是,应用中每个电池都要有一个强大而安全的电池管理系统(BMS)板。
无人机正朝着工业 4.0 的方向发展,这就要求机器人更加智能、更加互联。必须将连接性和数据安全性集成到包括 BMS 在内的所有现有系统中。此外,当机器人与环境互动时,安全性成为关键问题。
在电动自行车应用中,电池可以部署在不同位置。它可以放在机架上,也可以集成在机架上,也可以作为机架放置,也可以采用双重配置。无论它在放在哪里,都应该保持轻巧且具备高能量密度。在这种情况下,BMS 可保护电池免受故障影响、管理其功能并延长其使用寿命。
英飞凌正通过开发和提供业界领先的解决方案,积极塑造 BMS 的未来。
英飞凌的解决方案组合范围广泛,包括 LDO、安全、内存、电池监控、预充电 FET、充电和放电 FET、平衡 FET 和栅极驱动器产品。该产品组合包括我们的 85 V 至 300 V N 沟道 MOSFET,非常适合电动工具、无人机、电动自行车和电动两轮车等应用。这些 MOSFET 凭借超低反向恢复电荷(Qrr)和出色的导通电阻(RDS), 降低了整体系统成本。
英飞凌的多种在 85 V - 300 V 范围内的 N 沟道 MOSFET 产品组合,可以满足您的工业和汽车应用需求。
在电池管理系统中,需要一种能为整个系统供电的紧凑、可靠的解决方案。同时,系统中集成了多个组件,用于管理电池电压的剧烈波动。英飞凌的电源管理 IC (PMIC) 产品组合可满足这些要求以及更多要求,包括最新的网络接口和汽车安全性。
PMIC 支持采用英飞凌 TRAVEO™、AURIX™ 和 PSoC™ MCU 系列的系统解决方案的小尺寸综合电源。集成在 PMIC 中的升压功能可避免在电池电压剧烈波动时发生系统停电。PMIC 的低静态电流降低了始终保持接通功能的待机电流。PMIC 符合 AEC-Q100 标准,而大量的系统安全功能有助于满足现代 ECU 的要求。
推荐用于 BMS 的 PMIC:
- S6BP20x 系列 PMIC 是适用于汽车和工业的单通道降压-升压 DC-DC 转换器
- S6BP501A 和 S6BP502A 3 通道输出 PMIC
- S6BP401A PMIC 是一款单芯片电源管理解决方案,具有 6 通道电源输出
- OPTIREG™ PMIC(Automotive):集成式多轨电源解决方案
在扩展内存和事件记录类别中,英飞凌提供了三种解决方案选项:
- 瞬间非易失性EXCELON™ F-RAM,最低功耗运行频率为 20、50 或 106 MHz,容量从 2 Mb 到 8 Mb。 使用串行 SPI/I2C 的读/写性能为 4 kb/s 至 4 Mb/s,或 8/16 位并行访问的读/写性能为 64 kb/s 至 4Mb/s。它具有耐辐射性并且 SER 较低。高耐用性、长数据保留时间和快速访问的结合使其非常适合非易失性数据记录。
- SEMPER™ NOR 闪存系列是英飞凌最新的高性能、安全、可靠的 NOR 闪存解决方案,集成了关键的安全功能。 借助SEMPER™ NOR 闪存,我们推出了业界首款符合 ASIL-B 标准且符合 ASIL-D 标准的 NOR 闪存。
- 我们的SEMPER™ Secure NOR Flash 以较低的总拥有成本为系统提供安全性、可靠性。 这款先进、安全且易于使用的 NOR 闪存设备以无与伦比的系统完整性保护代码和数据免受黑客攻击。
SEMPER™ Secure闪存基于成熟的 SEMPER™™ NOR 闪存架构构建,将高级安防性与行业领先的功能安全性和可靠性相结合,并设计为终身使用。

PMIC 支持采用英飞凌 TRAVEO™、AURIX™ 和 PSoC™ MCU 系列的系统解决方案的小尺寸综合电源。集成在 PMIC 中的升压功能可避免在电池电压剧烈波动时发生系统停电。PMIC 的低静态电流降低了始终保持接通功能的待机电流。PMIC 符合 AEC-Q100 标准,而大量的系统安全功能有助于满足现代 ECU 的要求。
推荐用于 BMS 的 PMIC:
- S6BP20x 系列 PMIC 是适用于汽车和工业的单通道降压-升压 DC-DC 转换器
- S6BP501A 和 S6BP502A 3 通道输出 PMIC
- S6BP401A PMIC 是一款单芯片电源管理解决方案,具有 6 通道电源输出
- OPTIREG™ PMIC(Automotive):集成式多轨电源解决方案
在扩展内存和事件记录类别中,英飞凌提供了三种解决方案选项:
- 瞬间非易失性EXCELON™ F-RAM,最低功耗运行频率为 20、50 或 106 MHz,容量从 2 Mb 到 8 Mb。 使用串行 SPI/I2C 的读/写性能为 4 kb/s 至 4 Mb/s,或 8/16 位并行访问的读/写性能为 64 kb/s 至 4Mb/s。它具有耐辐射性并且 SER 较低。高耐用性、长数据保留时间和快速访问的结合使其非常适合非易失性数据记录。
- SEMPER™ NOR 闪存系列是英飞凌最新的高性能、安全、可靠的 NOR 闪存解决方案,集成了关键的安全功能。 借助SEMPER™ NOR 闪存,我们推出了业界首款符合 ASIL-B 标准且符合 ASIL-D 标准的 NOR 闪存。
- 我们的SEMPER™ Secure NOR Flash 以较低的总拥有成本为系统提供安全性、可靠性。 这款先进、安全且易于使用的 NOR 闪存设备以无与伦比的系统完整性保护代码和数据免受黑客攻击。
SEMPER™ Secure闪存基于成熟的 SEMPER™™ NOR 闪存架构构建,将高级安防性与行业领先的功能安全性和可靠性相结合,并设计为终身使用。
