RELAY UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18662106 titled 'RELAY UNIT
Simplified Explanation: The patent application describes a relay unit that includes busbars, a relay device, and a heat dissipation structure. The unit facilitates the flow of electric current between an external charging device and an in-vehicle battery.
- The relay unit consists of a first busbar that connects the charging connector of an external device to the in-vehicle battery.
- A relay device is positioned on the first busbar to control the flow of electricity.
- A second busbar links the in-vehicle battery to a power conversion device.
- The first busbar branches off from the second busbar and includes a path for electric current to flow through the relay device.
- A heat dissipation structure is incorporated to dissipate heat generated along the first busbar.
Key Features and Innovation:
- Integration of busbars, a relay device, and a heat dissipation structure in a relay unit.
- Efficient transfer of electric current between an external charging device and an in-vehicle battery.
- Controlled flow of electricity through the relay device.
- Branching of the first busbar from the second busbar to optimize the current path.
- Heat dissipation structure to manage and dissipate heat generated during operation.
Potential Applications: The technology can be applied in electric vehicles, hybrid vehicles, and other battery-powered devices that require efficient charging and power management systems.
Problems Solved: The relay unit addresses issues related to the efficient transfer of electric current between external charging devices and in-vehicle batteries, as well as the management of heat generated during operation.
Benefits:
- Improved efficiency in charging and power management systems.
- Enhanced safety through controlled flow of electricity.
- Increased reliability and longevity of the relay unit components.
- Optimal heat dissipation for sustained performance.
Commercial Applications: The technology can be utilized in the automotive industry for electric and hybrid vehicles, as well as in various industrial applications requiring efficient power management systems.
Questions about the Technology: 1. How does the heat dissipation structure enhance the performance of the relay unit? 2. What are the specific safety features incorporated in the relay device to ensure controlled flow of electricity?
Original Abstract Submitted
A relay unit includes a first busbar, a relay device, a second busbar, and a heat dissipation structure. The first busbar forms at least a part of an electric current path between a connecting portion, which is connected to a charging connector of an external charging device, and an in-vehicle battery. The relay device is provided on the first busbar. The second busbar forms at least a part of an electric current path between the in-vehicle battery and a power conversion device. The first busbar is branched at a branch portion from the second busbar, and includes at least a part of an electric current path extending from the branch portion to the connection portion via the relay device. The heat dissipation structure dissipates the heat from at least a part of the first busbar between the branch portion and the relay device.
