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.

Potential Applications: This technology can be applied in electric vehicles, hybrid vehicles, and other battery-powered systems where efficient and accurate charging is essential.

Problems Solved: - Ensures proper charging of the battery by matching the charging voltage. - Prevents overcharging or undercharging of the battery. - Improves the efficiency of the charging process.

Benefits: - Enhanced battery life and performance. - Efficient and accurate charging process. - Improved safety by preventing overcharging.

Commercial Applications: The technology can be utilized in the automotive industry for electric and hybrid vehicles, as well as in other industries that rely on battery-powered systems for efficient and reliable charging processes.

Questions about the Technology: 1. How does the communication between the automobile controller and power supply controller work? 2. What are the potential implications of using a boost converter to adjust the voltage for charging the battery?

Frequently Updated Research: Stay updated on the latest advancements in battery charging technology and electric vehicle systems to enhance the efficiency and performance of the technology described in the patent application.


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.
