Abstract: an electronic device includes a battery pack, a charging circuit that charges the battery pack, a load device that operates with a power of the battery pack, a voltage sensor that detects a charge voltage and a discharge voltage of the battery pack, a current sensor that detects a charge current and a discharge current of the battery pack, and a control circuit. the control circuit calculates an internal resistance of the battery pack based on the charge voltage and the charge current, calculates an allowable power indicating a maximum power that is able to be acquired from the battery pack by the load device based on the discharge voltage, the discharge current, and the internal resistance, and sends a control signal to the load device to cause the load device to operate with a power less than or equal to the allowable power.

IPC Code(s): H02M7/04
Abstract: a power supply device is connectable to a single-phase ac power supply or a multi-phase ac power supply. the power supply device includes power conversion circuits, a relay circuit, and a processor. the relay circuit is capable of switching between a first state and a second state. in the first state, a power supply line of each phase of the multi-phase ac power supply is connected to a corresponding power conversion circuit. in the second state, a power supply line of the single-phase ac power supply is connected to two or more of the power conversion circuits. the processor controls output timing of a control signal for operating the relay circuit on the basis of a detected temperature. the output timing is controlled such that, the first state is switched to the second state at timing when an ac voltage of the single-phase ac power supply crosses zero.
