  • 最大寿命 TME:每节电池为 3.3V 时,为 ±1.8mV(-40°C 至 +125°C)
  • 同时连续测量电池电压
  • 可配置的集成低通滤波
  • 用于高压电池组的可堆叠架构
  • 内置式 isoSPI 接口
    • 2Mbps 隔离式串行通信
    • 使用一根双绞线,每段最长 20 米
    • 低 EMI 易感性和辐射
    • 双向断线保护
    • 电容器或变压器耦合
  • 可热插拔,无需外部保护
  • 无源单元平衡,每通道高达 300mA,具有可编程 PWM
  • 多达 10 个通用模拟输入或数字 I/O
    • 温度或其他传感器输入
    • 可配置为 I2C 或 SPI 控制器
  • LPCM 可在关机状态下进行电池和温度监控
  • 休眠方式电源电流为 4 μA
  • 对母线的规定

ADBMS6830B 是多单元电池组监控器,可测量最多 16 串联电池单元,在全温度范围内,使用寿命总测量误差 (TME) 小于 2mV。ADBMS6830B 的测量输入范围为 -2V 至 +5.5V,适用于大多数电池化学成分,并可测量母线电压。为绕过母线而不指定任何测量通道做出了规定。

可以使用两个单独的模数转换器 (ADC) 同时和冗余地测量所有电池。具有 4.096 MHz 高采样速率的连续运行 ADC 可减少外部模拟滤波,并获得无混叠测量结果。后续可编程无限脉冲响应 (IIR) 滤波器可以实现更高的降噪效果。

可将多个 ADBMS6830B 串联在一起,从而对长的高电压电池串进行同步单元监控。每个 ADBMS6830B 都有一个隔离室串行端口接口 (isoSPI™),用于进行不受 RF 干扰的远距离高速通信。多个套件以菊花链模式连接在一起,并共用一个主机处理器连接。此菊花链可以双向操作,即使在沿通信路径发生故障的情况下,也能确保通信完整性。

ADBMS6830B 可由电池组供电,或由隔离式电源供电。ADBMS6830B 包括具有独立脉冲宽度调制 (PWM) 占空比控制的无源平衡和每节电池高达 300mA 的放电电流。其他功能包括板载 5V 稳压器、多达 10 个 GPIO 和休眠方式,电流消耗降至 4 μA。

产品详情

The EVAL-ADBMS6830BMSW is a full-featured evaluation board for the ADBMS6830B, a 16-channel battery stack monitor for broad market applications. This board allows multiple boards to be linked through a single twisted pair wire interface (isoSPI) to monitor a long series of cells in a stack. It provides access to full channel monitoring to all cells going to battery pack either in the supply line or in the V+ to V- line. The evaluation board also features reversible isoSPi that can access either path to do measurement functions and serve as a redundant communication path. The PCB, components, and DuraClik connectors are optimized for low EMI susceptibility and emissions.

APPLICATIONS

  • Mobile Robot System
  • E-scooter/E-bikes/Light Electric Vehicle
  • Agricultural Gateway Hubs
  • Metering Technology
  • Power Tools
  • Portable Energy Storage System
  • Industrial Equipment Battery Monitoring
