A device management method of a device management apparatus that manages information of devices installed in a home, includes: acquiring electric power consumption per unit time in predetermined time intervals, for each of branch circuits of a power distribution board to which the devices can be connected; estimating existence of the devices connected to the branch circuit, based on change of electric power consumption over time, per unit time; condition determining whether or not an estimated device, which is a device regarding which existence has been estimated in the estimating, satisfies a predetermined condition; and transmitting inquiry information to a user in accordance with the predetermined condition, only in a case where determination is made in the condition determining that the estimated device satisfies the predetermined condition.

A portable standby starting device for a vehicle includes a battery circuit, a load access detecting circuit, and a vehicle starting circuit. The battery circuit is coupled to the load access detecting circuit and the vehicle starting circuit, and is configured to supply power to the load access detecting circuit and the vehicle starting circuit; the load access detecting circuit is coupled to the vehicle starting circuit, and is configured to detect whether the vehicle starting circuit is connected to a vehicle load; the vehicle starting circuit is configured to, when the load access detecting circuit detects the connection of the vehicle load, output a vehicle starting current for controlling an ignition operation performed for the vehicle.

The disclosure relates to a method of renewable energy tracking and directing. Renewable energy production, storage, and consumption are tracked, and then attributed to different applications. The method can optimally attribute renewable energy to carbon-displacing applications to maximize carbon impact and monetization of carbon displacement. Additionally, blockchain technology is used to unalterably record the carbon traces.

Various embodiments include a method for certifying at least one installation-specific amount of energy, wherein the installation-specific amount of energy has been generated or consumed by an energy installation of an energy system. The method may include: capturing a temporal measured signal accumulated in relation to the energy system of a measured variable associated with the amount of energy; transmitting the captured signal to a test unit external to the energy system; disaggregating the transmitted signal using the test unit, and ascertaining the installation-specific amount of energy by way of the disaggregation; issuing a certificate regarding the ascertained installation-specific amount of energy; and receiving the issued certificate at the energy system.
