  • Patent number: 11217834
    Abstract: An energy storage unit for a motor vehicle battery is provided, having an energy store, particularly configured as a battery cell module, for storing and delivering electric power. A measuring device measures electrical properties of the energy store. An evaluation unit, connected to the measuring device, ascertains the operational status of the energy store from the measurement results of the measuring device. An indicator unit is connected to the evaluation unit for depicting the operational status of the energy store. By ascertaining and depicting the operational status and not just the state of charge of the energy store, it is possible to dispense with separate complex measurements when fitting the energy store, so that an energy storage unit can be checked quickly and efficiently when fitted into a motor vehicle.

  • Patent number: 11211793
    Abstract: A solar system installed at a house or building, which may include solar panels and a solar inverter. When the solar system is installed at the house or building, the power load associated with the solar system might overload an electrical panel. This might force the owner of the house or building to spend thousands of dollars on an electrical panel upgrade. To avoid such an expensive upgrade, a smart load manager (SLM) is disclosed that can communicate with the solar inverter and can control it. The SLM can function as a real-time load shedding device, thereby avoiding the cost of a load center/panel upgrade, while enabling a safe and cost-effective solar system installation.

  • Patent number: 10380963
    Abstract: The present application includes a display driving circuit, driving method thereof, and display device. A voltage detection circuit is added to an existing display drive circuit, and the voltage detection circuit determines, according to a standard reference voltage signal outputted by a logic circuit, whether a reference voltage signal outputted by a power supply management circuit is abnormal. If the reference voltage signal is determined to be abnormal, the power supply management circuit is controlled to stop outputting the reference voltage signal, such that the power supply management circuit is in a static mode, and therefore, a display panel is in a constant white or constant black mode.

  • Patent number: 10361629
    Abstract: An improved power manager includes a power bus (410) and multiple device ports (1-5), with at least one device port configured as a universal port (3 and 4) to be selectively connected to the power bus over an input power channel that includes an input power converter (510) or over a output or universal power channel (412, 416) that includes an output power converter (440, 442). The universal power channel (412) allows the input port (4) to be selected as an output power channel instead of an input power channel (i.e. operated as a universal port) for outputting power to device port (4) over power converter (440). The improved power manager (500) includes operating modes for altering an operating voltage of the power bus (505), to minimize overall power conversion losses due to DC to DC power conversions used to connect non-bus voltage compatible power devices to the power bus.

  • Patent number: 10361560
    Abstract: A power system control instruction device performing a control instruction to the control device that controls the power system on the basis of a measured value transmitted from a sensor measuring a state value of the power system and a method for performing such a control instruction are provided. The device obtains a centralized control amount using a measured value of the sensor such that a system voltage meets a predetermined control purpose, and creates a distributed control model using the measured value and the centralized control amount. The device then determines whether or not a voltage deviation from the voltage appropriate range occurs when the control device performs control on the basis of the distributed control model, and re-creates the distributed control model when the voltage deviation occurs, and transmits the distributed control model that is re-created to the control device.
