德州仪器 (TI) 的 bq27320 单节电池电量监测计只需进行极少的配置和系统微控制器固件开发工作，有助于实现快速系统调通。bq27320 采用补偿放电终点电压 (CEDV) 电量监测算法进行电量检测，可提供诸如剩余电量 (mAh)、充电状态 (%)、续航时间（分钟）、电池电压 (mV)、温度 (°C) 和健康状况 (%) 等信息。
TI 客户可使用 TI 基于网络的工具 GAUGEPARCAL 调整化学参数。
可配置中断有助于节省系统功耗，释放主机使其停止继续轮询。外部热敏电阻为精确温度感测提供支持。
通过 bq27320 进行电池电量监测时，只需将 PACK+ (P+)、PACK- (P-) 以及选装的热敏电阻 (T) 连接至一个可拆卸电池组或嵌入式电池电路即可。此器件使用一个 15 焊球 NanoFree（芯片尺寸球栅阵列 (DSBGA)）封装, 是空间受限类应用的 理想选择。

General notes
Overview
SingleCellbqProduction offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy and finally validating limits for calibration parameters to spike out any inconsistencies in material. SingleCellbqProduction offers three(3) levels of access to allow strict control over the manufacturing process with the assembly line operator only having access to the "Start" button. SingleCellbqProduction supports 1 station from a single computer and has inbuilt capability to maintain log files for the processed printed circuits boards. The bqMTester hardware is incompatible with some single cell gauges.
Operating systems: Windows XP, Windows 7, Windows 10
Requires: MKST-3P-ALT-EV2300 (MKS-SAI-001), Precision voltage and current source/sink for calibration.
