Open Source Visual Basic Battery Monitoring Software

Smart Battery Reader (SBR) is a professional Windows application for Smart Battery communication, testing, monitoring, and automated charge/discharge cycling via SMBus/I²C. Designed for battery engineers, developers, researchers, and manufacturers, it supports battery characterization, validation, production testing, fuel gauge development, and long-term aging analysis. Features include real-time monitoring of up to 125 battery parameters, live graphs, programmable data logging, CSV export, Data Flash editing, GG file import/export, firmware programming (SREC), SHA-1 authentication, SMBus command console, and advanced reporting. Compatible with Texas Instruments fuel gauges including bq40z50, bq27742, and bq27z561. Supports Aardvark I²C adapter, programmable power supplies, electronic loads, and automated battery cycling for capacity, internal resistance, cell balancing, and performance evaluation.

Bq40zXX SREC Viewer is a Windows utility that reads, analyzes and extracts Texas Instruments battery fuel gauge Data Flash settings directly from Motorola SREC (S-Record) firmware files. It allows developers to generate fully compatible GG (Golden Image) files without programming a battery or using BQStudio to read Data Flash first. The software supports BQ40z50, BQ40z50-R1/R2/R3/R4/R5, BQ40z60, BQ40z80 and BQ40z370 firmware versions. Features include SREC analysis, GG extraction, parameter search, Data Flash viewer, bit register visualization, graphical overview of key settings, HEX export, report printing and fast firmware inspection. Ideal for battery developers, BMS engineers, firmware engineers, production, validation and technical support working with Texas Instruments Smart Battery fuel gauges.

Notebook Battery Logger is a Windows application for real-time monitoring, logging and analysis of notebook battery performance. It displays detailed battery information, automatically calculates State of Health (SOH), supports notebooks with one or two batteries, and records battery parameters at user-defined intervals. Features include live graphs of voltage, current, RSOC, OS RSOC, Full Charge Capacity (FCC), current capacity and charge cycles, delayed logging start, CSV export, automatic e-mail delivery of log files, Windows Powercfg Battery Report and Power Efficiency Diagnostics integration, raw battery driver data viewer and battery configuration options. Ideal for battery diagnostics, validation, troubleshooting, long-term battery analysis, engineering, technical support and battery performance evaluation.
