ELECTRONIC DEVICE AND METHOD FOR DETERMINING CHARGING CONDUCTIVITY

An electronic device includes a charging circuit and a bypass circuit. The charging circuit adapted to charge a battery of the electronic device. The bypass circuit is connected in parallel with the charging circuit. A controller is configured to selectively turn on or turn off the bypass circuit with a first switch connected in series with the bypass circuit and to selectively turn on or turn off the charging circuit with a second switch connected in series with the charging circuit. The controller further configured to: measure a first voltage from upstream of the charging circuit with both the bypass circuit and the charging circuit being turned off; measure a second voltage from upstream of the charging circuit with the bypass circuit being turned on and the charging circuit being turned off; compare the first voltage with the second voltage; and determine a charging conductivity based on the comparison result.
