ELECTRIC VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240309947 titled 'ELECTRIC VEHICLE

The abstract of the patent application describes an electric vehicle with various components such as an electric motor, a power transmission device, an electric oil pump, cooling oil passage, lubricating oil passage, branch portion, oil cooler, and a control valve.

  • The electric vehicle includes an electric motor for propulsion.
  • A power transmission device is connected to the electric motor for transferring power.
  • An electric oil pump is used to discharge oil within the system.
  • A cooling oil passage supplies oil to the electric motor for cooling purposes.
  • A lubricating oil passage supplies oil to the power transmission device for lubrication.
  • A branch portion distributes oil between the cooling and lubricating oil passages.
  • An oil cooler is provided in the cooling oil passage to regulate temperature.
  • A control valve in the branch portion adjusts the flow rate of oil based on temperature.

Potential Applications: - Electric vehicles - Automotive industry - Energy-efficient transportation

Problems Solved: - Efficient cooling and lubrication of electric motor and power transmission device - Temperature regulation for optimal performance

Benefits: - Improved efficiency and performance of electric vehicles - Extended lifespan of components - Reduced maintenance costs

Commercial Applications: Title: "Enhanced Cooling and Lubrication System for Electric Vehicles" This technology can be utilized in the production of electric cars, buses, and other electric vehicles to enhance their performance and durability. It can also be integrated into electric vehicle charging stations to optimize the charging process.

Questions about the technology: 1. How does the control valve in the branch portion regulate the flow rate of oil? - The control valve adjusts the flow rate of oil based on the temperature of the oil, allowing for optimal cooling and lubrication of the components. 2. What are the potential cost savings associated with implementing this enhanced cooling and lubrication system in electric vehicles? - By improving the efficiency and longevity of the electric motor and power transmission device, this technology can lead to reduced maintenance costs and increased overall savings for vehicle owners.


Original Abstract Submitted

an electric vehicle includes: (a) an electric motor; (b) a power transmission device to which the electric motor is connected; (c) an electric oil pump configured to discharge an oil; (d) a cooling oil passage configured to supply the oil to the electric motor for cooling the electric motor; (e) a lubricating oil passage configured to supply the oil to the power transmission device for lubricating the power transmission device; (f) a branch portion configured to distribute the oil between the cooling oil passage and the lubricating oil passage; (g) an oil cooler provided in the cooling oil passage; and (h) a control valve which is provide in the branch portion and which is configured to make a ratio of a flow rate of the oil distributed to the lubricating oil passage higher when a temperature of the oil is low than when the temperature of the oil is high.
