CHARGING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240266848 titled 'CHARGING DEVICE

The abstract describes a charging device with a bypass power line and an earth leakage detector to ensure safe charging of a battery.

• The charging device has a bypass power line that connects the terminals when the earth leakage detector is activated.
• The earth leakage detector interrupts the power line if the sum of currents is not zero, ensuring safety.
• The controller manages the power flow to connect the battery for charging when the earth leakage detector is bypassed.
• Charging of the battery begins once the bypass power line is disconnected.

Potential Applications: - This technology can be used in electric vehicle charging stations to ensure safe and efficient charging. - It can also be applied in industrial settings where battery charging is a critical process.

Problems Solved: - Ensures safety during battery charging by detecting earth leakage and interrupting power flow. - Provides a reliable and efficient method for charging batteries without risking damage.

Benefits: - Improved safety during battery charging processes. - Efficient and reliable power management for charging devices.

Commercial Applications: Electric vehicle charging stations can benefit from this technology to enhance safety and efficiency in charging processes.

Questions about the Technology: 1. How does the earth leakage detector ensure safety during battery charging?

  - The earth leakage detector interrupts the power line if the sum of currents is not zero, preventing potential hazards.

2. What are the potential applications of this technology beyond battery charging?

  - This technology can also be applied in industrial settings where safe and efficient power management is crucial.

Original Abstract Submitted

the charging device includes a bt first/second terminal, a ps first/second terminal, a first/second power line, a bypass power line, and an earth leakage detector. when the first/second power line is passing through and the sum of the currents flowing through the first/second power line is other than zero, the earth leakage detector interrupts the first/second power line. the bypass power line bypasses the earth leakage detector and connects the bt second terminal to the ps first terminal. the controller disconnects the power from the ps first (second) terminal. the controller connects a battery to the bt first (second) terminal and also connects the ps first terminal and the bt second terminal through the bypass power line. if the earth leakage detector is activated, the bypass power line will be disconnected. then, charging of the battery is started.
