Battery Management Studio (bqStudio) 软件
Battery Management Studio (bqStudio) 提供一整套稳健的工具来帮助您评估、配置、测试 TI 电池管理产品以及利用其进行设计或以其他方式对其加以利用。这包括提供对寄存器和数据内存的完全访问，其中包括支持实时查看、绘制和记录轻松连接以发送命令、控制低级通信和 I/O，以及自动和指导支持配置、校准、执行学习周期以及生成有用的文件以将器件投入生产。
bqStudio 不支持 bq20xxx 和 bq30xxx 等旧产品。可从相应的产品页面下载特定的评估软件。您为 bqStudio 下载的最新化学物质更新程序也需要更新版 bqStudio。
参考设计
具有精确电池测量和高侧 MOSFET 控制功能的 10 节至 16 节串联电池包参考设计
此参考设计是一款待机和运输模式电流消耗低、电芯电压精度高的 10-16 芯串联锂离子、磷酸铁锂电池包设计。它能够非常精确地监控各电芯的电压和温度、电池包电流和 MOSFET 温度，并防止锂离子、磷酸铁锂电池包出现电芯过压、欠压、过热和充放电过流以及放电短路现象。采用高侧 N 沟道 MOSFET 架构，具有强大的驱动开关能力。利用高效的辅助电源策略，此参考设计可实现 100μA 待机功耗和 10μA 运输模式功耗，因此能够节省更多能源并实现更长的运输时间和空闲时间。借助上述特性，此参考设计非常适用于电动自行车和电动踏板车电池包应用。
