In high-performance charging systems, managing higher currents is crucial for efficient battery charging. Elevated battery temperature is the main challenge for limiting the duration and effectiveness of high-current charging. Our proposal of control system addresses these barriers by optimizing charging time by maintaining optimal temperature ranges for the battery. This is achieved through innovative preconditioning solutions that are incorporated with active Battery cooling configurations.
Our system features a unique preconditioning approach with dedicated active cooling circuit for the battery which will provide cooling to battery even though cabin HVAC (Heat Ventilation & Air-conditioning unit) is switched off. The active liquid cooling system ensures effective temperature management without additional energy consumption, while the dedicated Battery active liquid cooling system provides enhanced cooling capabilities for more demanding scenarios and preconditioning. By integrating these cooling configurations, our control system reduces charging time and maintains higher currents for extended periods, ensuring efficient and safe battery charging.
This paper will discuss the methodology and implementation of our advanced control system, highlighting the benefits of our preconditioning solutions in maintaining optimal temperatures during high-current charging. The simulation results demonstrate the potential of our system to revolutionize high-performance charging by overcoming thermal limitations and enhancing overall efficiency.
