Abstract
An apparatus and method for determining a power supply electrical current capacity. In one example, an operating circuit is placed into an operating mode that causes the operating circuit to have a determined electrical current consumption. A charging circuit that is electrically connected in parallel with the operating circuit is configured to provide a maximum charging current to a power pack. After configuring the charging circuit, a value of a measured charging current provided to the power pack is received. After receiving the value of the measured charging current, an electrical current supply capacity value of the external power supply is determined as a function of the determined electrical current consumption and the value of the measured charging current.
