Hello, Secretary Dong! I learned that the company's Hall current sensors have been used in the battery pack modules of CATL. As the core device for sensing current in the electric control box, how many Hall current sensors are needed for the battery pack of each electric vehicle, and what is their value?

Baolong Technology: Hello investors, thank you for your attention to Baolong Technology! The product that the company supplies to CATL is the fluxgate current sensor, and one is used per bicycle. In addition, the company's Hall current sensors are also supplied to other customers, and generally 5-6 are used per bicycle.
