Group 1: Battery Development Challenges - During the high-power charging process, battery overheating can significantly affect its long-term lifespan, necessitating effective temperature control [1]. - The two core strategies for temperature control are reducing battery heat generation (lowering internal resistance) and enhancing the cooling capabilities of the battery system [1]. - The company aimed for an internal resistance of 0.30 mΩ, while the industry standard was around 0.5 mΩ, with leading suppliers estimating a minimum of 0.38 mΩ [1]. Group 2: Technical Achievements - The company formed a specialized task force that spent one year overcoming the technical challenges associated with achieving the target internal resistance [1]. - A high-precision model was developed to decouple the internal resistance of the battery cell into three layers and 17 components, which is more detailed than the industry norm of two layers and 5-6 components [1][2]. Group 3: Charging Performance and User Satisfaction - The company set ambitious goals for battery performance, including a range of over 700 km (CLTC) and the ability to charge 400 km in just 10 minutes [4]. - By March 2024, the company aims to achieve a charging time of 12 minutes for 500 km, with subsequent improvements leading to 19 minutes and 15 minutes for 95% charge by mid-2024 [4]. - User satisfaction regarding charging (NPS) has increased from 91.6 to 98.4, indicating a positive reception of the charging performance improvements [4].
