HIMA Maextro S800 huawei catl battery pack

10.5-Minute Charge (10% to 80% SOC): The S800 redefines charging efficiency with its 6C ultra-fast charging capability, slashing downtime and maximizing productivity for electric vehicles (EVs) and hybrid systems.

High-Voltage Architecture: Optimized for rapid energy transfer without compromising battery longevity or safety.


As the industry’s first extended-range battery to offer a 65kWh capacity, the S800 delivers extended driving ranges and sustained power for heavy-duty applications.

Integrated Wireless High-Voltage Box: Eliminates traditional wiring harnesses, reducing weight, complexity, and potential failure points while enhancing reliability.


Anti-High Voltage Short Circuit: Proprietary thermoelectric isolation technology prevents electrical hazards, ensuring stable performance under extreme conditions.

Downward Venting for Passenger Safety: High-temperature gases and smoke are directed downward during thermal events, shielding occupants and critical systems from harm.


Dual Large-Surface Liquid Cooling System:

  • 2x Faster Cooling Rate: A dual-sided liquid cooling system accelerates heat dissipation, maintaining optimal battery temperatures even during high-load operations.
  • 4x Larger Cooling Area: Compared to conventional bottom-only cooling designs, the S800’s expanded thermal management surface ensures consistent efficiency and prolongs battery life.
