The system includes a plurality of branch circuits including a plurality of branch relays, the plurality of branch relays coupled to at least one busbar and configured to be coupled to a plurality of circuit breakers, a deadfront arranged in front of the plurality of branch relays, and a neutral busbar arranged in front of the deadfront and coupled to the plurality of circuit breakers through openings in the deadfront. The deadfront may be an installer deadfront.

Integrated electrical panel

A valve includes a holder having an expandable material. The valve includes a retainer coupled to the holder. The valve further includes an umbrella member with a stem coupled to the holder. The expandable material is adapted to expand in size when absorbing a fluid and translate the umbrella member along an axis of the stem.

Automatic reset flood valve

The system includes one or more busbars couple to an AC line, branch relays each coupled to a busbar and to a respective circuit breaker, and current sensors each corresponding to at least one respective branch relay of the plurality of branch relays. The system also includes a deadfront arranged in front of the plurality of branch relays, and including openings corresponding to the branch relays allowing an electrical terminal of each branch relay to protrude forward through a respective opening. A circuit breaker is engaged with each respective branch relay, on the deadfront to create an array of branch circuit breakers. The combination of relay and circuit breaker allows each branch circuit to be controllable. The relays may include current sensors, such as a shunt, used to determine a branch circuit current and control the relay. Control circuitry manages the relay on-off operation and monitors branch circuit operation.

A system for managing electrical loads includes a plurality of branch circuits, a sensor system, and control circuitry. The sensor system is configured to measure one or more electrical parameters corresponding to the plurality of branch circuits, and transmit one or more signals to the control circuitry. The control circuitry is configured to determine respective electrical load information in each branch circuit based on the sensor system, and control the electrical load in each branch circuit using controllable elements based on the respective electrical load information. The control circuitry transmits usage information, generates displays indicative of usage information, accesses stored or referencing information to forecast electrical load, and manages electrical load in response to identified events. The control circuitry can associate each branch circuit with reference load information, and disaggregate loads on each branch circuit based on the reference load information and on the electrical load in the branch circuit.

Systems and methods for managing electrical loads

An electromagnetic switch including a first stationary electric contact, a second stationary electric contact, a mechanical contact, and a moveable contact. The electromagnetic switch is configured for reciprocal motion of the moveable contact into and out of contact with the first stationary electric contact and the second stationary electric contact, wherein the moveable contact remains in contact with the mechanical contact (e.g., a non-conducting contact) throughout the reciprocal motion. In various embodiments, the moveable contact is configured so that at the end of the reciprocal motion three contact points occur, and a triangle defined by the three contact points encloses a center of force of the reciprocal motion.

An energy storage system includes: a host; energy storage modules; a plurality of nodes, each implemented at a corresponding one of the energy storage modules and configured to monitor and control that energy storage module; a communications and data transmission medium forming a loop from a first portion of the host and sequentially through the nodes to a second portion of the host; and in each of the nodes, first and second devices configured to perform at least partially redundant communication and data transmission functions using the communications and data transmission medium.

Functional redundancy of communications and data transmission in energy storage system

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.

Multi-channel and bi-directional battery management system

An electromagnetic switch includes: at least two stationary electric contacts; and a moveable contact, wherein the electromagnetic switch is configured for reciprocal motion of the moveable contact into and out of contact with the stationary electric contacts, wherein the moveable contact is configured so that at least three contact points occur in the reciprocal motion, and so that a triangle defined by the at least three contact points encloses a center of force of the movement.

Wire break detection in redundant communications

A system and method for low-cost, fault tolerant, EMI robust data communications, particularly for an EV environment. A data communications method, including a) enabling a transmission of a wake signal from a host to a remote client through an isolator disposed at the remote client when the wake signal is asserted from the host at a host-portion of the isolator concurrent with a periodic enablement of a client-portion of the isolator by the remote client; and thereafter b) transmitting the wake signal from the host to the remote client through the isolator; c) controlling enablement of the client-portion responsive to the wake signal transmitted through the isolator; and thereafter d) disabling the transmission by deassertion of the wake signal at the host.
