瑞萨电子的汽车无线电池管理系统 (BMS) 无需使用线束，可以灵活放置电池，简化了可扩展电动汽车的开发。

系统优势：

  • 无需使用 BMS 所需的传统线束，减轻了重量并节省了空间，同时提高了灵活性
  • 能在整个生命周期内更轻松地更换和重复利用电池
  • 瑞萨电子用于无线 BMS 的低功耗蓝牙低能耗 (LE) 5.1 设备*1 非常适合用于根据开放式蓝牙 LE 标准进行电池生命周期标准化，而非根据单个供应商独有的专有无线协议
  • 具有低功耗蓝牙 MCU 模块的单电芯/低功耗蓝牙系统，方便灵活拆装电芯
  • 无线 BMS 的系统级功能安全概念正在准备中

*1: DA14531 是工业级设备。 汽车级产品正在开发中。
