• All-Domain Intelligent Temperature Control – Lifespan increased by 7%, system efficiency improved by 2%, and all-weather system efficiency exceeds 88%:
  1. Innovative breakthroughs in traditional thermal management boundaries with a multidimensional lateral cooling architecture.
  2. Heat exchange area increased by 14%.
  3. Achieves ±2°C precise temperature control at the cell level, improving temperature consistency within a single cell by 30%.
  4. Overall system temperature difference maintained below 3°C.
  5. Lifespan increased by 7% compared to traditional liquid-cooled battery packs.
• Intelligent Temperature Control Algorithm based on lithium iron phosphate battery electrochemical polarization principles:
  1. Charging and discharging efficiency increased by 1%.
  2. Power consumption of the thermal management system reduced by 30%.
  3. Overall system efficiency improved by 2%.
• AI Intelligent Active Balancing – Maintenance-free throughout the battery’s lifecycle, addressing battery consistency issues:
  1. Precise assessment of battery consistency based on AI big data models, with an error of less than 3%.
  2. Dynamic control algorithms and energy-transfer-based active balancing BMS enable intelligent and efficient consistency control, avoiding the barrel effect.
  3. Increased usable energy over the entire lifecycle by 9.7%.
  4. IRR improved by 2.2%, with a reduction in payback period by 6.7%.
• Cell-Level Targeted Fire Safety – Continuous targeted spraying without ignition:
  1. Fault location at the cell level.
  2. PfH-Perfluorohexane targeted spraying for rapid cooling.
• Comprehensive Safety Control Technology – Coordinated safety design across “electric-thermal-mechanical” fields ensures extreme product safety:
  1. Enhanced insulation at the cell level, unaffected by coolant leakage.
  2. Real-time insulation monitoring and lightning protection.
  3. Comprehensive temperature monitoring and dual redundancy sampling for cell voltage, ensuring high reliability against over-temperature, over-voltage, and under-voltage.
  4. Four levels of short-circuit protection.
  5. Multiple thermal isolation measures to prevent thermal propagation.
  6. Extreme stress intensity design for all cycles and scenarios.
  7. Cloud-based big data analysis for early warning of failures.
  8. 176 testing verifications ensure the product’s safety and reliability.
