Hybrid Drive Power Control Using Battery and Fuel Cell Damage Forecasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid drive systems in vehicles fail to optimize the combination of battery device output power and fuel cell system operating power to extend the service life of both components, often leading to increased damage to one component while the other suffers reduced service life.
Innovation Solution
A controlling method that monitors and stores the operating power of the fuel cell system and the output power of the battery device over a measurement period, using damage models to forecast future damage and adjust the target output power and operating power to balance the damage between components, thereby extending the service life of the hybrid drive system.

Engineering Contradiction Analysis
1Power
If the output power of the battery device is increased to meet power demand, then the power demand is satisfied, but the damage to the battery device increases and service life is reduced
Solution Approach 1:
The system performs preliminary assessment of damage status for both battery device and fuel cell system before meeting power demand. By measuring and storing operating parameters over a measurement period and determining damage status in advance, the control system can predict future damage forecasts and adjust power distribution proactively to prevent excessive damage to either component, thereby extending service life while meeting power requirements.
2Power

3Productivity
If only current operating situation is considered when combining output power and operating power, then the power demand is met efficiently, but the long-term service life of components is compromised due to unbalanced damage
Solution Approach 1:
The system continuously measures and stores operating parameters of both battery device and fuel cell system over a measurement period. Based on this feedback data, the control unit determines damage status for each component and uses this information to adjust power distribution. This feedback mechanism ensures that both power demand satisfaction and component service life are optimized by balancing the damage between components.
