POWER SUPPLY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18606183 titled 'POWER SUPPLY SYSTEM
Simplified Explanation
The patent application describes a power supply system that includes relays and a control device to manage the flow of electricity between a high-voltage battery and electrical equipment. The system can charge the high-voltage battery and prevent abnormal voltage reductions in a low-voltage battery.
- The power supply system has a main relay and a charging relay controlled by a control device.
- The system charges the high-voltage battery while the relays are closed.
- A relay interruption unit interrupts the charging relay before the main relay in case of a low-voltage battery abnormality.
Key Features and Innovation
- Integration of main relay, charging relay, and control device for efficient power management.
- Ability to charge high-voltage battery and prevent abnormal voltage reductions in low-voltage battery.
- Relay interruption unit for prioritized interruption in case of battery abnormalities.

Questions about Power Supply System
How does the relay interruption unit prioritize interruptions in case of battery abnormalities?
The relay interruption unit is designed to interrupt the charging relay before the main relay to prevent further damage to the system in case of a low-voltage battery abnormality.
What are the potential market implications of implementing this power supply system in electric vehicles?
Implementing this power supply system in electric vehicles can lead to improved battery performance, increased safety, and enhanced overall efficiency, making them more attractive to consumers and potentially increasing market demand.
Original Abstract Submitted
A power supply system includes a main relay provided on a high-voltage path between a high-voltage battery and electrical equipment, a charging relay provided on a charging path connected between the main relay and the electrical equipment, and a control device that controls opening and closing of the main relay and the charging relay. The control device, the main relay, and the charging relay operate using electrical power supplied from a low-voltage battery. In a state in which the main relay and the charging relay are closed, the high-voltage battery is charged by charging it with power supplied from a charging device. In addition, the power supply system includes a relay interruption unit that interrupts the charging relay before interrupting the main relay if a voltage reduction abnormality of the low-voltage battery has occurred under a state in which both the main relay and the charging relay are closed.
