A power management technique is provided that operates with regard to a dynamic sleep threshold voltage. If a device's battery voltage is greater than the dynamic sleep threshold voltage, a voltage rail for the device is collapsed during a sleep mode for the device. Conversely, if the battery voltage is less than the dynamic sleep threshold voltage, the voltage rail is sourced during the sleep mode for the device.

There are provided methods, devices, and systems relating to discharging thyristor-switched capacitors. For example, there is provided a method for discharging the capacitors (C A , C B , C C ) of a thyristor-switched capacitor, TSC, device (100) coupled to a transmission line (102a, 102b, 102c). The method includes determining whether an angle of a voltage on the transmission line (102a, 102b, 102c) is within a threshold angle. Further, the method can include operating the device (100) in a discharging mode when the angle is within the threshold angle and the threshold angle is in a predetermined set of threshold angles.

A storage battery apparatus provided in a consumer's facility comprises: a communicator configured to communicate with an external equipment control apparatus in accordance with predetermined communication protocol; and a controller configured to execute load following discharge in which discharge power is adjusted according to power consumption of a load provided in the consumer's facility. The communicator receives a set request for requesting setting the maximum discharge value of the load following discharge from the equipment control apparatus. The controller controls the discharge power of the load following discharge not to exceed the maximum discharge value based on the set request.

The present disclosure discloses a battery management system that uses a small number of opto-couplers to reduce a production cost. The battery management system is controlled to maintain a turn-off state in a normal condition. Also, switches are connected in series, and the switches are connected such that when any one switch turns on, switches connected subsequent to the turned-on switch turn on in sequential order. The turn-on of the last connected switch causes a switch turning on an opto-coupler to be turned on. As a result, when the opto-coupler turns on, a battery management device may transmit information to an external device.

A fuel cell system includes a battery, auxiliary machines including an actuator and a heater that heats cooling water circulating in the fuel cell. The actuator is driven to cause gas to be supplied to a fuel cell configured to generate electric power using the gas. Furthermore, the fuel cell system includes a warming-up operation unit that adjusting operations of the auxiliary machines so as to realize output of fuel cell such that a predetermined electric power is extracted, a discharge control unit that supplies the electric power from the battery to the auxiliary machines when electric power generated by the fuel cell is lower than electric power consumed by the auxiliary machines. Furthermore, the fuel cell system includes an auxiliary machine restriction unit that restricts electric power consumed by the actuator when the discharge control unit supplies the electric power from the battery to the auxiliary machines in a case where the fuel cell is warmed up using the heater.
