Abstract
The described technology provides an apparatus including a power supply unit (PSU) and a PSU control system stored in the memory and executable by the one or more processor units, the PSU control system encoding computer-executable instructions on the memory for executing on the one or more processor units a computer process, the computer process including receiving internal temperatures of the PSU over a duration of time, determining multiple exponential weighted moving average (EWMAs) of the internal temperature of the PSU for the duration of time, comparing the EWMA with a temperature threshold associated with the duration of time, and based at least in part on determining that EWMA exceeds the temperature threshold associated with the duration of time, limiting the output power of a charger using a charger current limit input to the charger. In an alternative implementation of the technology disclosed herein, the computer process includes receiving an initial condition of the PSU such as sensed PSU power level for a duration of time, determining multiple EWMA of the sensed PSU power level for the duration of time, comparing the EWMA with a sensed power level threshold associated with the duration of time, and based at least in part on determining that EWMA exceeds the sensed power level threshold associated with the duration of time, limiting the output power of a charger using a charger current limit input to the charger.
