JAC Group , Maextro S800 has demonstrated excellent performance in many aspects. Its power battery system uses Huawei Jujing Battery 2.0 (ternary lithium battery provided by CATL Kirin Battery), and mica materials play a key role in battery thermal management and structural safety.
· Advantages of Mica Materials for Power Batteries
· Thermal management optimization : In the battery system of Zunjie S800, mica material plays a vital role in thermal management. The battery adopts CTP design, and the battery cell is directly embedded in the battery pack, which improves energy density while optimizing heat dissipation. Mica plates have good high temperature resistance and can remain stable in a high temperature environment of 200°C. They effectively assist high-safety thermoelectric separation architectures, dual large-surface liquid cold plates and other components to prevent thermal runaway of the battery. In addition, the thickness of the mica plate is relatively small. This feature enables it to not take up too much volume in a limited battery space, and can efficiently conduct and block heat. Thinner mica plates can fit more closely to battery cells and other heat dissipation components, reduce gaps in the heat transfer path, thereby improving heat dissipation efficiency, ensuring that the battery maintains a suitable temperature during charging and discharging, and improving battery performance and service life.
· Enhanced structural safety : The bottom protection of the battery pack is made of insulating mica paper and double-layer aviation-grade profile plate, the side adopts a triangular beam thickening design, and the side beam is thickened by 75%. Mica paper has high mechanical strength and good flexibility. When impacted, it can effectively disperse stress and protect the internal structure of the battery from damage. The advantage of its small thickness is also reflected here. Thin mica paper can be more flexibly compounded with other protective materials to form a tight protective layer. Without significantly increasing the weight of the battery pack, it greatly improves the impact resistance of the battery pack and reduces the risk of battery damage in accidental situations such as collisions, providing solid protection for the safety of vehicles and passengers. At the same time, mica material is resistant to acid, alkali and aging, and can maintain stable performance for a long time in complex usage environments, further extending the service life of the battery pack.
· Other shining features of S800
· Strong performance : Available in pure electric and extended-range versions, the pure electric version has excellent range, such as the dual-motor CLTC pure electric range of about 400 kilometers; the extended-range version is equipped with a 1.5T generator. High charging efficiency, with 6C ultra-fast charging technology, SOC 10%-80% only takes 10.5 minutes (based on 6C current).
· Intelligent and advanced : Equipped with Huawei Tuling Longxing platform, it supports 16° crab angle, 120km/h open road tire burst stability control, and has L3 intelligent driving architecture. The Angel Seat active safety protection system can achieve 360° omnidirectional collision prevention, and has multiple protection operations before collision. It is also equipped with Huawei Galaxy communication technology, which supports ultra-reliable information transmission.
· Unique design : Large body size, fastback coupe shape, 30% lower drag coefficient, multiple colors available. The interior features a triple screen design, crystal ceiling lights, and other advanced features such as a "starry sky ceiling".
· High-end market positioning : Positioned as an ultra-luxury flagship car in the new energy era, with an estimated retail price of RMB 1 million to 1.5 million, it represents a new height in China's luxury car market.
The Maextro S800 (Chinese: 尊界S800; pinyin: Zūnjiè S800) is a battery electric full-size ultra-luxury sedan manufactured by JAC Group under the Maextro brand, a collaboration with Huawei's HIMA(Harmony Intelligent Mobility Alliance) multi-brand automotive alliance. It is positioned as the flagship vehicle of HIMA. ————From Wikipedia
