Charge

Driving current into a cell so that lithium ions leave the positive electrode and are stored in the negative one, raising the cell voltage. It needs an external supply at a voltage above the cell’s own.

Cutoff voltage

The terminal-voltage limit that ends a discharge, or caps a charge — in constant-current, constant-voltage (CC-CV) charging the cell is then held at that voltage until the current falls to a cutoff. A real discharge ends at the lower cutoff, which is why actual runtime can differ from the ideal duration.

Depth of discharge

How much of a cell’s capacity is used in a cycle. Deep cycles cause more mechanical stress in the active materials than shallow ones.

Discharge curve

The plot of terminal voltage against delivered capacity at a given current and temperature. Its shape identifies the chemistry — LFP is flat, NMC slopes — and its area is the delivered energy.

Load

Whatever draws current from the battery — a motor, an inverter, a resistor in a test. Loads are specified by current, power or resistance, and a battery’s behaviour depends on which of the three stays constant.
