德州仪器 (TI) BQ27427 电池电量监测计是一款单节电池电量监测计，只需极少的用户配置和系统微控制器固件开发，就能够快速启动系统。
通过对三种化学配置文件进行预编程，尽可能减少用户配置，并帮助用户管理项目中不同电池化学成分的库存。BQ27427 电池电量监测计在睡眠模式下具有超低功耗，有助于延长电池运行时间。可配置的中断有助于节省系统功耗并使主机免于连续轮询。外部热敏电阻支持精确的温度检测。
BQ27427 电池电量监测计使用已获专利的 Impedance Track™ 算法来进行电量监测，并提供诸如剩余电量 (mAh)、荷电状态 (%) 和电池电压 (mV) 等信息。
使用 BQ27427 电量监测计进行电池电量监测时，只需连接至可拆卸电池包或嵌入式电池电路的 PACK+ (P+) 和 PACK- (P-)。微型的 9 球、1.62mm × 1.58mm、0.5mm 间距 NanoFree™ 芯片级封装 (DSBGA) 非常适合空间受限的应用。

Battery Management Studio (bqStudio) Documentation
Battery Management Studio (bqStudio) offers a full suite of robust tools to assist with the process of evaluating, designing with, configuring, testing, or otherwise utilizing TI Battery management products. This includes features that provide full access to registers and data memory including support for real-time watching, graphing, and logging, an easy interface to send commands, direct low-level communication and I/O, as well as automated and guided support for configuration, calibration, performing a learning cycle, and generating useful files for taking the device to production.
Older products such as bq20xxx and bq30xxx are not supported in bqStudio. Download the specific evaluation software from the appropriate product page.
Requires: EV2400 or MKST-3P-ALT-EV2300
Software installer to enable BQEVSW to use MKST-3P-ALT-EV2300
Software manifest
Description:
BQEVSW-MKST-UPDATE software is a software update for BQEVSW (bq Evaluation Software) and BQEASY (bq EV-Easy) to allow it to work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. This update installs a program that allows switching the USB transceiver target in software like BQEVSW and BQEASY from/to EV2300 to/from MKST-3P-ALT-EV2300.
The program requires administrator privileges.
Requirements:
Features:
Getting started:
1. Download the software
2. Run the installer and check the option to create shortcuts
3. Run the program using shortcut named BQEVSW-MKST-UPDATE from Start menu/Desktop
4. Allow administrator privilege when/if prompted
5. On the GUI window that opens, select the target transceiver to support and follow steps to switch
6. Connect matching transceiver and start BQEVSW, BQEASY or other similar software.
Note: BQMTESTER-MKST-UPDATE and BQEVSW-MKST-UPDATE both update the same software components. Switching the USB transceiver using any of these shortcuts will also switch it in the other.
