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 coolants, and a valve to control the flow of coolant to the heat exchanger.

  • The control apparatus is able to diagnose failures in the valve or the battery cooling line when the battery overheats.
  • It can also control the fuel cell output to cool the stack coolant and the battery by using the temperature of the stack coolant in case of a valve or component failure in the battery cooling line.

Potential Applications

  • This technology can be applied in fuel cell electric vehicles to efficiently manage the thermal conditions of both the fuel cell stack and the battery.

Problems Solved

  • Overheating of the battery in a fuel cell electric vehicle can lead to performance degradation and safety risks. This technology helps diagnose and address failures in the cooling system to prevent battery overheating.

Benefits

  • Improved thermal management of the fuel cell stack and battery, leading to enhanced performance and safety of the vehicle.
  • Ability to diagnose and address failures in the cooling system, ensuring proper functioning of the vehicle's components.


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.
