Abstract: An intelligent charge-discharge controller for a battery includes a charging voltage test circuit configured for testing an input voltage of the battery when in charge; a charging current control circuit configured for controlling an input current of the battery based on the tested input voltage; a battery voltage test circuit configured for testing a current voltage of the battery; and a discharging current control circuit configured for controlling a discharging current of the battery. The charging voltage test circuit and the battery voltage test circuit each are electrically connected to the charging current control circuit, and the charging voltage test circuit and the discharging current control circuit have a common circuit section. An electronic device having the intelligent charge-discharge controller is also provided.
