CONTROLLING REVERSE IN-RUSH CURRENT FOR VEHICLE CHARGERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18059578 titled 'CONTROLLING REVERSE IN-RUSH CURRENT FOR VEHICLE CHARGERS
Simplified Explanation
The abstract describes a system for controlling reverse in-rush current for vehicle chargers by detecting an in-rush current from the battery to the charger and adjusting the voltage at the DC link accordingly.
- The system includes a controller to determine the voltage at the DC link of a charger used to power a battery of an electric vehicle.
- The controller detects an in-rush current from the battery to the charger based on the voltage at the DC link being greater than a reference value.
- The system helps prevent damage to the charger and battery by controlling the in-rush current during charging.
Potential Applications
This technology can be applied in electric vehicle charging stations, home charging systems, and industrial charging solutions.
Problems Solved
This technology helps prevent damage to the charger and battery caused by excessive in-rush current during charging.
Benefits
The system ensures safe and efficient charging of electric vehicle batteries by controlling reverse in-rush current.
Potential Commercial Applications
The technology can be used in electric vehicle charging infrastructure, battery management systems, and smart grid solutions.
Possible Prior Art
One possible prior art could be systems that regulate in-rush current in power electronics or battery charging applications.
Unanswered Questions
How does the system differentiate between normal charging current and in-rush current?
The system likely uses voltage levels at the DC link to distinguish between normal charging current and in-rush current.
What impact does controlling reverse in-rush current have on the overall charging time of the battery?
Controlling reverse in-rush current may slightly increase the charging time of the battery due to the regulation of current flow, but it helps prevent damage and ensures the longevity of the charger and battery.
Original Abstract Submitted
Controlling reverse in-rush current for vehicle chargers is provided. A system can include a controller to determine a first value of voltage. The voltage can be of or associated with a DC link of a charger to output power to a battery of an electric vehicle. The controller can detect an in-rush current from the battery to the charger. The detection can be responsive to the first value of voltage at the DC link being greater than a reference value of voltage established for the DC link.
