In a first embodiment multiple power sources are selected and then combined. Selecting power rather than controlling power may be a cheaper way of controlling the amount of power delivered. In a second embodiment the logic to control power is removed from the battery charger so that the logic may be changed when a different battery is being charged. This permits all types of batteries to be charged if the power source is compatible with the battery. Other embodiments expand the types of power sources that may be used.
Control Of Electrical Power Used To Charge An Energy Storage Device
In a first embodiment an electrical power request is sent to a energy storage device charger. This charger uses a controllable power source that supplies requested power. The electrical power request may be created in various ways. The request may be programmed into a power-requesting device or the power-requesting device may develop the request using information about the device to be charged. One programmable requesting device may be used for all energy storage devices or each energy storage device may use it own power-requesting device that develops a power request specific to the energy storage device.In a second embodiment a power-requesting device develops the power request based partly on sensor information from the energy storage device.In a third embodiment the power delivery plug is selectable.
A sail arrangement having a hollow flexible boom with a short stiffener rod disposed therein near the forward end, and a stiffener tube which may be moved along the exterior of the boom. The flexible boom provides both automatic sail positioning and the spilling of excess wind during sudden strong gusts. In a second embodiment, a pivoted rigid boom is controlled by an elastic cord. In a third embodiment, a spring assembly permits the mast to pivot to spill the wind during strong gusts.
Systems composed of chargers that allow vehicles to control parameters of power, or that allow vehicles to receive power having parameters the power connector usually is used for, or parameters that a charger estimated based on voltage that the charger measures at the vehicle's connector, or that has parameters that a charger calculated based information about the vehicle's energy storage device that the vehicle sends to the charger.
Externally Controllable Battery Charger Having A Signal Interpreter
In a first embodiment a first signal generator associated with a first power consuming device sends information about the first power consuming device to a signal interpreter associated with a controllable power source. The signal interpreter develops a control signal in response to the information. The control signal is sent to a controllable power source. The controllable power sends power to the first power consuming device in accordance with the control signal it receives from the signal interpreter. The first signal generator and the first power consuming device that is associated with it are abbe to be removed so that a second signal generator associated with a second power consuming device may communicate with the signal interpreter. The controllable source sends power to the second power consuming device in accordance with the control signal it receives from the signal interpreter.A second embodiment is the same as the first except now the signal interpreter is able to understand commands from a signal generator that develops commands instead of information.
External Control Of Power By Using Powered Device Specifications
A powered device has a specifications storage device. Specifications are sent to an interpreter that converts specifications into power supply control signals. The specifications storage device and powered device can be removed. They are replaced with a new powered device and a specification storage device that contains specifications of the new powered device.
Methods Of Controlling Externally Controllable Power Supplies
In a first embodiment a powered device has a director that creates directions such as “increase power” or “decrease power”. The directions are sent to a voltage source controller in an externally controllable power supply. The voltage source controller creates control signals so as to comply with the directions. The signals control the level of voltage that a power source delivers to the powered device. In a second embodiment the same powered device has the same director and creates the same directions as in the first embodiment. The directions are sent to a current source controller in an externally controllable power supply. The current source controller creates control signals so as to comply with the directions. The signals control the level of current that a power source delivers to the powered device.References CitedU.S. Patent Documents
