ELECTRIC VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18612245 titled 'ELECTRIC VEHICLE

Simplified Explanation: The patent application describes an electric vehicle with a charger that charges a high-voltage battery using power from an external source. The charger is connected to the battery via a relay switch controlled by a control apparatus.

  • The charger is designed to start charging the high-voltage battery after a predetermined time delay to ensure safe and efficient charging.
  • The control apparatus maintains the relay in a closed state until the charger is ready to begin charging the battery.
  • This system helps prevent damage to the battery cells by gradually increasing their voltage during the charging process.

Key Features and Innovation:

  • Charger for high-voltage battery in electric vehicle.
  • Control apparatus for delayed charging start.
  • Relay switch for connecting charger to battery.
  • Gradual voltage increase for battery cells.

Potential Applications: This technology can be applied to electric vehicles, hybrid vehicles, and other battery-powered devices that require efficient and safe charging systems.

Problems Solved:

  • Ensures safe and efficient charging of high-voltage batteries.
  • Prevents damage to battery cells during charging process.
  • Optimizes battery performance and longevity.

Benefits:

  • Improved battery charging efficiency.
  • Enhanced battery cell protection.
  • Extended battery life span.

Commercial Applications: The technology can be utilized in the automotive industry for electric and hybrid vehicles, as well as in the development of advanced battery charging systems for various applications.

Questions about Electric Vehicle Charging System: 1. How does the control apparatus determine the predetermined time delay for starting the charging process? 2. What are the potential implications of this technology on the electric vehicle market in terms of efficiency and sustainability?


Original Abstract Submitted

An electric vehicle including a charger configured to charge a high-voltage battery with an electric power supplied from an external power source. The charger is disposed on an electric path that is to be connected to and disconnected from the high-voltage battery by switching of a relay. When the high-voltage battery is to be charged by the charger, a control apparatus executes a charging-start-stage control by which a closed state of the relay is maintained until a predetermined time elapses after the relay is switched to the closed state in response to connection of the external power source, wherein the predetermined time is predetermined as a period in which the charger actually starts charging the high-voltage battery and a voltage of battery cells included in the high-voltage battery is increased.
