BATTERY CONTROL SYSTEM AND METHOD OF FUEL CELL VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17981882 titled 'BATTERY CONTROL SYSTEM AND METHOD OF FUEL CELL VEHICLE

Simplified Explanation

The patent application describes a battery control system and method for a fuel cell vehicle. Here is a simplified explanation of the abstract:

  • The system consists of a battery, a fuel cell, and a controller.
  • The battery is responsible for providing driving energy to the vehicle.
  • The fuel cell can either provide driving energy to the vehicle or charge the battery.
  • The controller is responsible for estimating the deterioration of the fuel cell.
  • Based on this estimation, the controller calculates the change rate in the state of charge (SOC) value of the battery.
  • The controller then adjusts the charge control factor or discharge control factor of the battery according to the derived change rate in the SOC value.

Potential applications of this technology:

  • Fuel cell vehicles: This technology can be applied to improve the efficiency and performance of fuel cell vehicles by optimizing the battery control system.
  • Renewable energy systems: The battery control system can be utilized in renewable energy systems that use fuel cells as a power source, ensuring efficient energy storage and utilization.

Problems solved by this technology:

  • Deterioration estimation: The controller solves the problem of estimating the degree of deterioration of the fuel cell, which is crucial for maintaining the performance and longevity of the system.
  • SOC value optimization: By adjusting the charge control factor or discharge control factor based on the change rate in the SOC value, the system solves the problem of optimizing the battery's energy management for improved efficiency.

Benefits of this technology:

  • Enhanced fuel cell performance: By adjusting the battery control factors based on the fuel cell deterioration, the system ensures optimal utilization of the fuel cell's driving energy, leading to improved performance.
  • Extended battery life: The ability to estimate and adjust the SOC value helps in preventing overcharging or deep discharging, which can extend the battery's lifespan.
  • Improved energy efficiency: The optimized battery control system ensures efficient energy storage and utilization, resulting in improved overall energy efficiency of the vehicle or renewable energy system.


Original Abstract Submitted

A battery control system and method of a fuel cell vehicle includes a battery, a fuel cell, and a controller. The battery provides driving energy of a vehicle. The fuel cell provides the driving energy of the vehicle or charging the battery. The controller estimates a degree of deterioration of the fuel cell, derive a change rate in an SOC value of the battery based on the degree of deterioration of the fuel cell, and change a charge control factor or a discharge control factor of the battery according to the derived change rate in the SOC value of the battery.
