Is the charging stack of the energy storage and charging station integrated or modular? If modular, what is the power of each module? How does the quantity of inductive transformers change after integration? There will be requirements for magnetic integration. The main challenge is how to achieve low power loss with high current. Inductive transformers must pursue high power and low loss, crucial for chargers providing a large number of inductive transformers. The magnetic materials used for inductors and transformers need to pursue high frequency and low loss, a significant characteristic. Higher integration theoretically results in better EMC and heat dissipation. For power supplies with power and inductive transformer modules, better integration can expedite compliance with standards or obtaining technical certificates. Power supply design involves magnetic integration, leading to higher power and increased heat. Therefore, inverters and some power boxes are moving towards liquid cooling. In our case, modularity may be adopted in the future. Modular designs are more standardized, facilitating production and use. However, current inductive transformers require material improvements and do not yet meet modular requirements. Charging stations will demand magnetic integration for inductive transformers due to the trend towards miniaturization. Magnetic integration reduces costs by minimizing the use of magnetic materials, structural components, and copper. Generally, for a 15kW application, magnetic integration designs are typically above 10kW. The integration of control modules affects the quantity of inductive transformers.
