SOLAR CHARGING USING ADJUSTABLE SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17839823 titled 'SOLAR CHARGING USING ADJUSTABLE SECONDARY BATTERY
Simplified Explanation
The abstract describes a solar energy charging system for a vehicle that includes a dynamically adjustable battery (DAB) connected to a solar energy conversion device. The DAB can be controlled to adjust its output voltage and supply electrical power to a vehicle battery assembly. A controller detects the input voltage to the conversion device, selects an output voltage for the DAB based on the input voltage, and controls the DAB to provide the selected output voltage to charge the battery assembly through a high voltage DC-DC converter.
- The system includes a dynamically adjustable battery (DAB) that can be controlled to adjust its output voltage.
- The DAB is connected to a solar energy conversion device and charged by it.
- The DAB supplies electrical power generated by the solar energy conversion device to a vehicle battery assembly.
- A controller is responsible for detecting the input voltage to the conversion device.
- The controller selects an output voltage for the DAB based on the detected input voltage.
- The DAB is controlled by the controller to provide the selected output voltage to a high voltage DC-DC converter.
- The high voltage DC-DC converter charges the vehicle battery assembly.
Potential Applications
- Solar energy charging systems for electric vehicles.
- Renewable energy integration into vehicles.
- Off-grid charging solutions for vehicles.
Problems Solved
- Efficiently charging a vehicle battery assembly using solar energy.
- Optimizing the output voltage of the battery to match the input voltage from the solar energy conversion device.
- Providing a dynamically adjustable battery that can adapt to different solar energy conditions.
Benefits
- Increased utilization of renewable energy for vehicle charging.
- Improved efficiency in charging the vehicle battery assembly.
- Flexibility to adjust the output voltage of the battery based on the input voltage from the solar energy conversion device.
Original Abstract Submitted
A solar energy charging system of a vehicle includes a dynamically adjustable battery (DAB) configured to be connected to a solar energy conversion device and charged by the solar energy conversion device. The DAB is controllable to adjust an output voltage of the DAB to one of a plurality of output voltages, and the DAB is configured to supply electrical power generated by the solar energy conversion device to a vehicle battery assembly. The solar energy charging system also includes a controller configured to detect an input voltage to the conversion device, select an output voltage of the DAB based on the input voltage, and control the DAB to provide the selected output voltage to a high voltage DC-DC converter to charge the battery assembly.
