ONBOARD POWER DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240174106 titled 'ONBOARD POWER DEVICE

Simplified Explanation

The abstract describes an onboard power device with a bidirectional charging circuit, AC inlet, AC outlet, switching relay, and voltage sensor.

• The power device includes a power storage device for storing electrical energy.
• The bidirectional charging circuit is connected to the power storage device via a first power line and can also be connected to an external power source via a second power line.
• An AC inlet allows the device to be connected to an external power source through a third power line.
• An AC outlet is installed in a cabin and connected to a fourth power line for providing power to devices inside the cabin.
• A switching relay selectively connects the second power line to either the third power line or the fourth power line.
• A voltage sensor, connected to the third power line, provides voltage information to a controller.

Potential Applications

The technology described in this patent application could be applied in electric vehicles, marine vessels, and off-grid power systems.

Problems Solved

This technology solves the problem of efficiently managing power sources and distribution within a confined space, such as a vehicle or a remote location.

Benefits

The benefits of this technology include optimized power utilization, increased energy efficiency, and enhanced safety features for onboard power systems.

Potential Commercial Applications

One potential commercial application of this technology is in the development of smart energy management systems for electric vehicles, which can improve overall performance and user experience.

Possible Prior Art

One possible prior art for this technology could be similar onboard power management systems used in electric vehicles or marine vessels.

How does the switching relay operate in different scenarios?

The switching relay in the onboard power device selectively connects the second power line to either the third power line or the fourth power line. This operation is controlled based on specific conditions or user input.

What safety features are incorporated in the voltage sensor and controller?

The voltage sensor in the device is designed to provide accurate voltage information from the external power source, ensuring safe charging and power distribution. The controller uses this information to regulate the flow of electricity and prevent any potential hazards.

Original Abstract Submitted

a onboard power device includes a power storage device, a bidirectional charging circuit connected to the power storage device via a first power line and connected to a second power line, an ac inlet configured to be connectable to an external power source and connected to a third power line, an ac outlet installed in a cabin and connected to a fourth power line, a switching relay configured to selectively connect the second power line to the third power line or the second power line to the fourth power line, and a voltage sensor including an input terminal connected to the third power line and an output terminal connected to a controller. the input terminal is electrically isolated from the portion between the switching relay and the power storage device.
