BQ27220 – Single cell pack/system-side CEDV battery fuel (gas) gauge w/pre-programmed chemistry profiles
https://www.electronics-lab.com/bq27220-single-cell-pack-system-side-cedv-battery-fuel-gas-gauge-w-pre-programmed-chemistry-profiles/
The Texas Instruments bq27220 battery fuel gauge is a single-cell gauge that requires minimal user configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27220 device uses the Compensated End-of-Discharge Voltage (CEDV) algorithm for fuel gauging and provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), […]

Fuel gauge needs no battery characterization
https://www.electronics-lab.com/fuel-gauge-needs-no-battery-characterization/
by Susan Nordyk @ edn.com The MAX17055 single-cell fuel gauge from Maxim not only eliminates battery characterization, but also keeps SOC (state-of-charge) error to within 1% in most scenarios. With its ModelGauge m5 EZ algorithm, the device provides tolerance against battery diversity for most lithium batteries and applications. It also allows system designer’s to decide […]

Maxim’s family of ModelGauge m5 standalone fuel gauges provides SHA-256 authentication with a 160-bit secret key to make it harder to clone battery packs. The ICs also implement the ModelGauge m5 algorithm, which converts raw measurements of battery voltage, current, and temperature into accurate state-of-charge (SOC%), absolute capacity (mAhr), time-to-empty, and time-to-full readings. by Susan […]
