Innovative Preconditioning Solutions for Efficient High-Current Battery Charging

In high-performance charging systems, managing higher currents is crucial for efficient battery charging. However, elevated battery and charging gun pin temperatures pose significant challenges, limiting the duration and effectiveness of high-current charging. Our advanced control system addresses these barriers by optimizing charging time while maintaining optimal temperature ranges for both the battery and charging gun. This is achieved through innovative preconditioning solutions that incorporate both active and passive cooling configurations. Our system features a unique preconditioning approach with dedicated cooling circuits for the charging socket and battery. The passive liquid cooling system ensures effective temperature management without additional energy consumption, while the active liquid cooling system provides enhanced cooling capabilities for more demanding scenarios. By integrating these cooling configurations, our control system significantly reduces charging time and maintains higher currents for extended periods, ensuring efficient and safe battery charging. This paper will discuss the design and implementation of our advanced control system, highlighting the benefits of our preconditioning solutions in maintaining optimal temperatures during high-current charging. The results demonstrate the potential of our system to revolutionize high-performance charging by overcoming thermal limitations and enhancing overall efficiency.
