Abstract: A discharge circuit for a power supply circuit for a motor is configured to discharge a capacitor provided in the power supply circuit. The discharge circuit includes a first voltage detector detecting a voltage inputted to a primary side of the power supply circuit, a second voltage detector detecting a voltage on the secondary side, and a discharge resistance provided in parallel with the power supply circuit on the secondary side of the power supply circuit. A power supply control means performs discharge control when a voltage detected by the second voltage detector exceeds a regenerative determination value and, in a case that a voltage on the primary side detected by the first voltage detector becomes lower than a power failure determination value, the power supply control means performs the discharge control after a lapse of a time period required for a stop operation of the industrial robot.

Abstract: A switching power converter is provided that communicates with a mobile device to receive a value of a load detection current. The switching power converter adjusts the cycling of a power switch until a constant current mode of operation is entered with a known output current driving the mobile device. The switching power converter subtracts the load current from the output current to measure a soft-short circuit current.

Abstract: A power storage system performing charging and discharging with an external system includes first and second battery units connected in parallel and each including a plurality of battery packs connected in parallel to a power converter. The power storage system includes a controller controlling operation of each power converter. The first and second battery units include a first battery pack and a second battery pack higher in internal resistance than the first battery pack, as the plurality of battery packs. The controller selects two second battery packs from a plurality of second battery packs included in the power storage system. In a standby state where charging and discharging are not performed with the external system, the controller performs, at different timings, control to discharge one of the selected two second battery packs and thereby charge the other, and control to discharge the other and thereby charge the one.

Abstract: Embodiments of information handling systems (IHSs) having rechargeable batteries and improved battery charge control methods are provided herein. For example, a method is disclosed for dynamically switching between a plurality of battery charging profiles, each having different recharge thresholds and charge termination thresholds for controlling battery recharge. Such a method may include detecting discharge current from a rechargeable battery of an IHS, determining whether or not the IHS is coupled to an external power source, and switching from using a first battery charging profile to using a second battery charging profile to recharge the rechargeable battery in response to detecting the discharge current while the IHS is coupled to the external power source and/or determining that the discharge current is a short term supplemental power event.
