THERMAL MANAGEMENT SYSTEM FOR A FUEL CELL ELECTRIC VEHICLE AND A METHOD FOR CONTROLLING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17974119 titled 'THERMAL MANAGEMENT SYSTEM FOR A FUEL CELL ELECTRIC VEHICLE AND A METHOD FOR CONTROLLING SAME

Simplified Explanation

The patent application describes a thermal management control apparatus for a fuel cell electric vehicle. It includes a cooling system for the fuel cell stack and the battery, a heat exchanger to exchange heat between the two cooling systems, and a valve to control the flow of coolant. The control apparatus can diagnose failures in the valve or the battery cooling line when the battery overheats and adjust the fuel cell output to cool both the stack coolant and the battery.

  • The patent application describes a thermal management control apparatus for a fuel cell electric vehicle.
  • The apparatus includes a cooling system for the fuel cell stack and the battery.
  • A heat exchanger is used to exchange heat between the stack coolant and the battery coolant.
  • A valve is included to control the flow of coolant to the heat exchanger.
  • The control apparatus can diagnose failures in the valve or the battery cooling line when the battery overheats.
  • The fuel cell output can be adjusted to cool both the stack coolant and the battery when a failure occurs.

Potential Applications

  • This technology can be applied in fuel cell electric vehicles to improve thermal management and prevent overheating of the battery.
  • It can be used in various types of fuel cell electric vehicles, including cars, buses, and trucks.

Problems Solved

  • Overheating of the battery in fuel cell electric vehicles can lead to reduced performance and potential damage.
  • The thermal management control apparatus solves the problem of diagnosing and addressing failures in the valve or the battery cooling line, which can contribute to battery overheating.

Benefits

  • The thermal management control apparatus ensures efficient cooling of both the fuel cell stack and the battery, optimizing the performance and lifespan of the vehicle.
  • By diagnosing and addressing failures in the cooling system, the apparatus helps prevent battery overheating and potential damage.
  • Improved thermal management can lead to increased overall efficiency and range of fuel cell electric vehicles.


Original Abstract Submitted

A thermal management control apparatus includes: a stack cooling line configured to cool a fuel cell stack of the fuel cell electric vehicle; a battery cooling line configured to cool a battery of the fuel cell electric vehicle; a heat exchanger configured to exchange heat between a stack coolant of the stack cooling line and a battery coolant of the battery cooling line; a valve configured to control an inflow of the stack coolant to the heat exchanger; and a control apparatus. The control apparatus is configured to diagnose whether a component of the valve or the battery cooling line has failed when the battery is overheated and to control a fuel cell output to cool the stack coolant and cool the battery by using a temperature of the stack coolant when a failure of the valve or a component failure of the battery cooling line occurs.
