Abstract:
1. A method for determining a power supply electrical current capacity, the method comprising: performing the following with a processor: placing an operating circuit into an operating mode that causes the operating circuit to have a determined electrical current consumption; configuring a charging circuit to provide a maximum charging current to a power pack, wherein the charging circuit is electrically connected in parallel with the operating circuit; receiving from a current meter, subsequent to the configuring, a measured value of charging current flowing through the power pack, wherein the current meter is electrically connected in series with the power pack; calculating, subsequent to the receiving, a fixed maximum electrical current able to be produced by an external power supply, detecting the operating circuit is in a second operating mode; determining that the second operating mode has an electrical current consumption greater than the maximum electrical current able to be produced by the external power supply; and configuring, in response to determining the second operating mode has an electrical current consumption greater than the maximum electrical current able to be produced by the external power supply, a charging circuit of an electronic device to supply the operating circuits with power from both the power pack and the external power supply.
