More specifically a controller and related control system for the energy balancing of the vehicle taking into consideration such factors as fuel usage, power management between the various power generating and storage sub-systems, regenerative braking, terrain topology, weather and other environmental conditions, operation of vehicle peripherals and parasitic power demands in addition to cargo management and environmental needs and driver comfort and safety, as well as vehicle fleet management.
ELECTRIC VEHICLE CHARGER WITH LOAD SHEDDING
Methods and apparatus for electric vehicle charger with load shedding. One embodiment provides a method of load shedding including receiving, at an electronic processor of an EV charger, an indication of an amount of current flowing through a main switchboard connected to the EV charger and determining, with the electronic processor, whether the amount of current exceeds a dynamic threshold. The method also includes reducing, using the electronic processor, a charge rating of the EV charger when the amount of current exceeds the dynamic threshold.
WIRELESS TRANSMISSION IN SHARED WIRELESS MEDIUM ENVIRONMENTS
Support of coexistence of wireless transmission equipment in shared wireless medium environments is disclosed, which is applicable to various types of wireless transmission equipment. For instance, a wireless power transmission system (WPTS) delivers power to wireless power receiver clients via transmission of wireless power signals using one or more frequencies and/or channels within shared wireless medium environments in which other wireless equipment is operating, such as access points and stations in wireless local area networks (WLANs). The WPTS is configured to co-exist with the operations of the other wireless equipment within the shared wireless medium environment by adapting its transmission operations to utilize frequencies or channels that do not interfere with other equipment and/or implementing co-channel and shared channels operations under which access to channels is implemented using standardized WLAN protocols such as PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.
In-wall power adapters and methods of implementing in-wall power adapters
An in-wall power adapter is described. The in-wall power adapter comprises a first contact element configured to receive power; an outlet coupled to receive power from the first contact element; and a recess having contact elements adapted to provide at least one of power signals and control signals; wherein the recess is adapted to receive a module.
Power systems with inverter input voltage control
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.
Load control system having a broadcast controller with a diverse wireless communication system
A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of energy controllers. Each energy controller is operable to control at least one of the electrical loads. The load control system also includes a first broadcast controller that has a first antenna and a second antenna. The first antenna is arranged in a first position and the second antenna is arranged in a second position that is orthogonal to the first position. The broadcast controller is operable to transmit a first wireless signal via the first antenna and a second wireless signal via the second antenna. Each of the energy controllers is operable to receive at least one of the first and second wireless signals, and to control the respective load in response to the received wireless signal.
Wire down detection system and method
Some embodiments of the invention include a method and system for metering an electrical grid comprising at least one processor executing instructions from a non-transitory computer-readable storage medium of an electrical grid fault detection system. In some embodiments of the system, the instructions cause a processor to calculate a prediction of whether power delivery to at least a portion of the electrical grid is functioning abnormally using voltage sensing devices coupled to at least one feeder, where one or more of the voltage sensing devices are responsive to a determination that the power delivery is functioning abnormally. Further in some embodiments, the determination includes the electrical grid fault detection system receiving at least one signal or voltage reading from the electrical grid based at least in part on a sensed or received voltage level or range of voltage level.
