Battery switch with current control
The present disclosure relates to a multifunction battery switch and method of connecting a battery pack to an external bus via the multifunction battery switch. The multifunction battery switch having a multifunctional controller, a plurality of switches, an inductor, and a resistor. Each of the plurality of switches is independently controllable via switch commands from the multifunctional controller. The inductor, the resistor, and the plurality of switches are arranged to define a buck-boost converter to selectively regulate power transfer between the battery pack and the external bus as a function of the switch commands from the multifunctional controller.

Power switch device
A power switch device includes a switch, a control unit, and a communication interface. The switch includes a power input terminal, which is configured to receive an external power; and a power output terminal, which is configured to output the external power. The switch normally remains open. The control unit is turned on when receiving the external power via the power input terminal, and transmits a start request via the communication interface. The control unit determines whether the communication interface receives a busy message within a delay time period. If the busy message is not received within the delay time period, the control unit controls the switch to be closed, and sets a start process time period. Within the start process time period, if the communication interface receives another start request, the control unit generates another busy message to respond to the another start request via the communication interface.
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.
