Designing Applications with Lithium Ion Batteries
by Roland van Roy
Li-Ion batteries have several advantages when compared with other battery types: The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. Li-Ion batteries have no memory effect, and the self-discharge is less than half compared to nickel-cadmium. The high cell voltage of 3.6 volts is often sufficient to power applications from a single cell...

Li-ion Battery and Gauge Introduction
by Vincent Ho
SOC (State-Of-Charge) is defined as the status of available energy in the battery and usually expressed as percentages. Because the available energy change depends on different charging/discharging currents, temperatures and aging effects, the SOC could be defined more clearly as ASOC (Absolute State-Of-Charge) and RSOC (Relative State-Of-Charge)...
