Power Glossary

VFG - Voltage fuel gauge (there's 2 type of fuelgauges, 2nd is coulomb-counter-based fuel gauges)
AICL - adaptive-input current limit
SOC - state-of-charge
OCV - open-circuit voltage
VFOCV - as per Maxim's integrated ModelGauge m5 algorithm: calculated open-circuit voltage of the cell as determined by the voltage fuel gauge. This value is used in other internal calculations.
OVP - over voltage protection
OPP - over power protection
OCP - over current protection
SCP - short circuit protection
OTP - over temperature protection
BOP - brown out protection
QH - Maxim's raw coulomb count generated by the device. This register is used internally as an input to the mixing algorithm.
VBYP - Vcc switch-over
RepSOC - in ModelGauge m5 algorithm, reported SOC (for use by the application GUI)
ELVSS - AMOLED negative power supply(amoled panel require negative voltage, so there's special ICs to generate ELVSS and ELVDD)
ELVDD - AMOLED positive power supply
