  • 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.
