Embodiments of the present invention include a battery management system that provide a plurality of channels that allow communication between host and clients. This communication may operate in bi-directional modes such that commands from the host and responses from the clients are transmitted clockwise or counter-clockwise around a daisy-chain loop. This architecture provides both a high level of redundancy across multiple channels as well as transmission directions around the loop. The use of multiple channels provides a separation in signal paths akin to the provision of completely separate physical wires, preventing malfunction of spurious operation of devices using one channel from interfering with the normal operation of devices using the other channel. In addition, the signaling architecture allows a host to dynamically transmit commands and receive responses between specific client(s) and host or broadcast communication across all clients.

In a power network system (10A), a plurality of power routers including at least a first power router (100A) and a second power router (100B) are connected through respective input/output terminal parts in a multi-stage configuration. A predetermined amount of power is transmitted to the input/output terminal part of the power transmission destination (230A) through a first input/output terminal part (210A), the input/output terminal part of the second power transmission source (220A), and the DC bus (201A) in the second power router. The power network system includes as power information about power in the input/output terminal part of the power transmission destination, identification information of the first power transmission source (110A), and an intermediate measurement value of power received in the first input/output terminal part in a predetermined time period.

An information terminal includes: a first communication unit that performs wireless communication with a wireless base station connected to a wide area network; a second communication unit that performs communication by a communication scheme different from the first communication unit; and a controller that: controls the second communication unit to receive first management information from a power management system that is installed in a facility and includes a storage battery, the first management information including information relating to the storage battery; and controls the first communication unit to transmit second management information generated based on the first management information received, to a server outside the facility as a destination, the server being connected to the wide area network.

A method and apparatus is described for providing energy system status information. A status indication device may be mounted near an entry door for determining when an individual is about to leave an area. When the status indication device determines that an individual is about to leave an area, it displays an energy status to the individual, so that the individual can decide whether to place energy-consuming devices in a conservation mode of operation.

Induction powered electrical current monitoring, and related devices, apparatuses, systems, and methods are disclosed. An electricity current monitoring device can include an inductive energy transfer medium, an energy storage device, a power management circuit, and a processing circuit. The inductive energy transfer medium can induce an electromotive force to produce electrical energy that can be stored in the energy storage device. A power management circuit can control storage of the electrical energy in the energy storage device and can control release of the electrical energy from the energy storage device. The processing circuit can measure the electrical current in the monitored energy source based on the fluctuating magnetic field generated by the inductive energy transfer medium. The processing circuit is electrically coupled to the power management circuit to be powered using the electrical energy released from the energy storage device.

A method for balancing electrical grid production with electrical grid demand, according to an exemplary aspect of the present disclosure includes, among other things, adjusting operation of an engine of an electrified vehicle during a drive event to either conserve a state of charge of a battery pack in response to a first grid condition of an electrical grid or deplete the state of charge of the battery pack in response to a second grid condition of the electrical grid.

Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.

A direct current (DC) bus voltage from a combined output of a plurality of DC power modules is controlled based on an alternating current (AC) voltage of a power grid. The DC bus voltage tracks the AC grid voltage to provide efficient conversion between the DC power sources and the AC grid, even when the amplitude of the AC grid voltage varies. In one example, a variable reference voltage is generated based on a detected AC grid voltage. The reference voltage increases and decreases in proportion to increases and decreases in the AC grid voltage. In this manner, large differences between the bus voltage and the grid voltage are avoided. By closely tracking the two voltages, efficiency in the modulation index for power conversion can be achieved.
