CC-CV charging

The standard lithium-ion charge protocol: constant current until the cell reaches its upper cutoff voltage, then that voltage held constant while the current tapers. The charge ends when the current falls to a set fraction, often C/20.

Charger

The power electronics that convert mains or DC supply into the controlled current and voltage a battery needs. For lithium-ion it runs the CC-CV profile within the limits the BMS communicates, and stops rather than floats when the cell is full.

Power-path management

Circuitry that routes power between an external supply, the battery and the system load, so the device runs from the supply while the battery charges, draws on the battery when the supply sags or fails, and adds battery current during peaks. An ideal-diode switch — a MOSFET driven to behave as a near-lossless diode — makes the changeover seamless.

Smart Battery System

A set of open specifications from the mid-1990s, begun by Duracell and Intel, under which a battery reports its own state over SMBus to the host and to a smart charger. The Smart Battery Data specification fixes the registers — voltage, current, remaining capacity, cycle count, requested charge current — so any compliant charger serves any compliant pack.
