CHARGING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18521604 titled 'CHARGING SYSTEM
Simplified Explanation: The patent application describes a system where an automobile controller communicates with a power supply controller to determine the charging voltage before charging the battery. The power supply controller adjusts the output voltage to match the charging voltage, and the automobile controller monitors the voltage to ensure proper charging.
- The automobile controller communicates with the power supply controller to determine the charging voltage.
- The power supply controller adjusts the output voltage to match the charging voltage.
- The automobile controller monitors the voltage to ensure proper charging.
- If the supply voltage is equal to the charge voltage, the battery is charged with that power. If the supply voltage is lower, a boost converter is used to adjust the voltage before charging the battery.
Key Features and Innovation: - Communication between automobile controller and power supply controller for determining charging voltage. - Voltage adjustment by power supply controller to match charging voltage. - Monitoring of voltage by automobile controller for proper charging. - Use of boost converter to adjust voltage if supply voltage is lower than charge voltage.

Original Abstract Submitted
The automobile controller notifies the controller of the power feed device (power supply controller) of the charging voltage prior to charging the battery. After receiving the charging voltage, the power feed controller raises the voltage at the output end of the power supply device to the supply voltage that is lower than its own rated output voltage and the charging voltage. The automobile controller monitors the voltage at the output end to identify the supply voltage while the power feed controller performs a ground fault check. The automobile controller (1) charges the battery with electric power of the supply voltage if the supply voltage is equal to the charge voltage, and (2) drives a boost converter to reduce the supply voltage to the charge voltage if the supply voltage is lower than the charge voltage, and then charge the battery with electric power from the power feed device.
