Abstract
A method of providing power includes providing no power to an output device if the output device cannot or should not use power. If the output device can use power, power is provided to the output device from an input source. If power available at the input source would not overload the output device, power is provided to the output device from the input source according to a maximum power point tracking algorithm. If power available at the input source would overload the output device, power is provided to the output device from the input source according to a target power.
Claims30
A method of providing power, comprising:
- providing no power to an output device if the output device cannot or should not use power;
- and
- providing power to the output device from an input source if the output device can use power as follows:
- providing power to the output device from the input source according to a maximum power point tracking algorithm when a power available at the input source would not overload the output device;
- and
- providing power to the output device from the input source according to a target power when the power available at the input source would overload the output device.
A power apparatus, comprising:
- a power supply comprising a supply input and a supply output configured to be electrically connected to an output device;
- and
- a controller for controlling the power supply, the controller comprising a maximum power point tracker that monitors the supply input;
- wherein the controller is configured to cause the power supply to:
- provide no power to the supply output if the output device cannot or should not use power;
- and
- provide power to the supply output from the supply input if the output device can use power as follows:
- provide power to the supply output from the supply input according to a maximum power point tracking algorithm performed by the maximum power point tracker when power available at the supply input would not overload the output device;
- and
- provide power to the supply output from the supply input according to a target power when the power available at the supply input would overload the output device.
A charging system, comprising:
- a photovoltaic device;
- a charging device electrically connected to the photovoltaic device, the charging device comprising a maximum power point tracker and a power supply;
- and
- a battery electrically connected to the charging device, wherein the charging device is configured to:
- provide no power to the battery if the battery is fully charged;
- and
- provide power to the battery from the photovoltaic device if the battery is not fully charged as follows:
- provide power to the battery from the photovoltaic device according to a maximum power point tracking algorithm performed by the maximum power point tracker when a maximum power of the photovoltaic device would not overload the battery;
- and
- provide power to the battery from the photovoltaic device according to a target power when the maximum power of the photovoltaic device would overload the battery.
