Power Supply System for Vehicles - A simplified explanation of the abstract
This abstract first appeared for US patent application 18625446 titled 'Power Supply System for Vehicles
Simplified Explanation
The patent application describes a system that detects abnormalities in the DCDC converter of a vehicle power supply system and takes corrective actions.
- When the voltage of the auxiliary battery is significantly different from the target voltage of the DCDC converter, the system stops the converter and activates the alternator.
- If the voltage of the auxiliary battery falls below a certain threshold, the system reduces the determination voltage value.
- The system also considers the internal resistance of the auxiliary battery to determine if there is an issue with the DCDC converter.
Key Features and Innovation
- Detection of abnormalities in the DCDC converter based on voltage differences.
- Activation of the alternator to maintain power supply.
- Adjustment of determination voltage value based on battery voltage levels.
- Consideration of internal resistance of the auxiliary battery for fault detection.
Potential Applications
This technology can be applied in automotive power supply systems to ensure efficient and reliable operation of DCDC converters.
Problems Solved
- Detecting abnormalities in the DCDC converter.
- Preventing power supply disruptions in vehicles.

Questions about the Technology
How does the system determine abnormalities in the DCDC converter?
The system detects abnormalities based on the voltage difference between the auxiliary battery and the target voltage of the converter.
What actions does the system take when an abnormality is detected?
The system stops the DCDC converter, activates the alternator, and adjusts the determination voltage value based on battery conditions.
Original Abstract Submitted
When the auxiliary battery is being charged and the difference between the voltage value of the auxiliary battery and the target voltage value of the DCDC converter is equal to or greater than the determination voltage value, the vehicle power supply system determines that the DCDC converter is abnormal, stops the DCDC converter, drives the alternator, and decreases the determination voltage value when the voltage value of the auxiliary battery is equal to or less than the predetermined voltage value or the internal resistance value of the auxiliary battery is equal to or less than the predetermined resistance value.
