概览

此解决方案专门针对国内电池供电发电机的 20 — 28 芯电池的电池管理系统 (BMS) 而设计。 该设计采用了瑞萨电子的多电池、单 IC 电池管理器，能够安全有效地监控电池寿命，并兼具来自 RA 系列 32 位 MCU 的成本优化系统控制。 此种组合为电池组板创建了一个系统，以便能够管理更高的电压并与各种负载设备进行交互。

系统优势：

  • 完整的大电压（40V 至 118V）独立 BMS
  • 系统健康检查/充电测量
  • 外部通信接口 (RS-485)
  • 设计可通过常见的安全法规

应用

  • 大型动力电机（电锯/HVAC）
  • 家庭/太阳能备份系统
  • 轻型电动汽车 (LEV)
