In 2023, Extreme Krypton (Configuration | Inquiry) Intelligent Technology held the “Winter Expedition Technology Conference”, once again ventured into the technology “no man’s land”, relying on the full-stack self-developed ecosystem, conquering the low temperature with the first four inventions in the industry and conquering the ice and snow with the three driving and control technologies, leading the technological innovation and development of the new energy automobile industry, and providing the optimal solution for users to travel in the whole scene in winter.
Conquering the low temperature also has the “Four Great Inventions” and the “Winter Sign Technology Conference” successfully held.
In-depth insight into users’ anxiety about pure electric travel in winter, and accurately solving the problem of low-temperature travel of trams, the extreme winter sign is not only a journey of technology and product verification, but also an important measure to accelerate the landing of the northern market strategy. As a high-end brand following the Nordic gene, Krypton has accumulated technology in the low-temperature environment for nearly a hundred years, and has formulated strict research and development standards. All new models must be tested in the extremely cold environment of the Arctic Circle in winter.
In the past 20 weeks, Krypton ranked first among domestic brands in the sales volume of pure electric vehicles with more than 200,000 in the northern market of China. With the all-round performance of all models in winter, excellent measured results and solid user reputation, journey to the south has a steady pace, and will continue to strengthen the layout of the northern market in the future to create a more extreme pure electric travel experience for more users.

Conquering Four Great Inventions of Low Temperature and Breaking the Winter Curse of Electric Vehicles
For a long time, the low temperature environment in the northern region has been regarded as the biggest pain point of electric vehicles, with low battery life, high energy consumption, slow heating and difficult charging, which seriously affects users’ car purchase decision and car experience.
Extreme Krypton takes “conquering low temperature” as the anchor point. In the core areas of low-temperature travel, such as vehicle thermal management, intelligent cockpit, power three-electricity, charging and recharging, the industry first launched four inventions, namely, nine-source heat pump, quick-heating frost-free air conditioner, 800V second-generation BRICS battery and 800V extremely cold liquid-cooled pole-filling pile, so as to truly achieve “low temperature as normal temperature” in the power performance, battery life and energy consumption of electric vehicles, and break the “trams can’t compete with mountains and seas”.
Conquering the low temperature also has the “Four Great Inventions” and the “Winter Sign Technology Conference” successfully held.
The industry’s first nine-source heat pump technology has the most heat sources, the widest temperature range and the most intelligent temperature control.
There are the most heat sources, and the nine-source heat pump breaks the heat barrier of the whole vehicle and reduces waste through the deep interaction of four waste heat sources, two waste heat sources and three auxiliary heat sources. Take the chip waste heat as an example, its recovery power can reach 1700 watts, which is equivalent to saving 1.7 kWh per hour, and the saved electricity can run 10 kilometers more.
The temperature range is the widest. The nine-source heat pump has the compressor with the largest displacement and the highest rotation speed in the industry, with the highest rotation speed exceeding 12,000 rpm, which can circularly compress more than 500 liters of refrigerant per minute. The widest working temperature range in the industry is -40℃~50℃, which effectively reduces heating power consumption and extends cruising range. At the low temperature of -20℃, krypton can still absorb environmental waste heat to heat the battery. Based on this, Krypton can save more than 1,800 watts per hour, which is equivalent to adding another 10 kilometers of cruising range.
The temperature control is the most intelligent. Based on the krypton full-stack self-developed intelligent thermal management algorithm, the nine-source heat pump can change the thermal energy flow strategy in real time according to the heating request of the whole vehicle, and replace the multi-key panel with one-key intelligence, bringing the industry’s most 300+ intelligent temperature control mode and rejecting every waste of thermal energy.

The only quick-heating frost-free air conditioner in the industry, the car air conditioner experiences the ceiling, allowing users to “air-condition freely” in winter.
Aiming at the problems of frosting in winter, slow temperature rise and high energy consumption of air conditioners that users vomit the most, krypton quick-heating frost-free air conditioners have made three major optimizations on heat exchange temperature difference, heat exchange area and heat exchange efficiency. Through the “refrigerant+coolant” dual-medium temperature control technology, the temperature difference of heat exchange is controlled within 2℃ to avoid frosting of external heat exchanger and ensure the rapid and continuous temperature rise of air conditioner; Through the optimized design of the flow channel of the integrated module, the cold and heat isolation is realized, the heat exchange area is increased and the heat exchange performance is improved; Using aerodynamic CFD technology for reference, the diameter and curvature of pipeline are optimized, and the flow resistance of coolant is reduced to half. In addition, Krypton has more than 140 patents in the fields of thermal management and air conditioning.
Under the joint action of the three optimizations, the comprehensive heat exchange efficiency of the quick-heating frost-free air conditioner can be improved by 130% compared with the traditional single-medium heat exchange method. The measured data show that after standing at -20℃ for 12 hours, it takes only 10 minutes for Krypton quick-heating frost-free air conditioner to raise the cabin temperature to 20℃, thus easily realizing “air conditioning freedom” in winter.

Full-stack self-developed 800V ultra-fast charging second-generation BRICS battery, the fastest charging battery in the world, leading the industry in low temperature performance.
The second-generation BRICS battery adopts the second-generation lithium ion acceleration technology developed by the whole stack, which reduces the comprehensive impedance at low temperature by 36% and improves the conductivity by 40%, so that lithium ions will naturally “swim in winter”; Self-developed composite heat shield insulation technology is adopted, with a polymer “insulation quilt” on the top to prevent heat energy from overflowing, and a precision-formed “down blanket” on the bottom to firmly lock the heat and realize three-dimensional insulation of the battery; Battery preheating and temperature maintenance function, when the vehicle power is less than 20%, the vehicle assistant will actively remind users to charge and recommend nearby charging stations. The thermal management system supports battery preheating function. The measured data show that after standing at -10℃ for 12 hours, the krypton 7X (configuration | inquiry) equipped with the second-generation BRICS battery can be charged from 10% to 80% in just 18 minutes, setting a new record for low-temperature ultra-fast charging and mass production.

In addition to the second-generation BRICS battery, the Krypton 800V ultra-fast rechargeable ternary lithium battery has the same excellent low-temperature performance. At -10℃, the low-temperature discharge capacity is increased by 3%, the thermal management energy consumption is reduced by 7%, and the vehicle life is increased by more than 30 kilometers. Take the extreme krypton 7X equipped with 100kWh Kirin battery as an example. In the scene of -10℃ outside the car and air conditioning at 21℃, the cruising range is measured to be 500 kilometers, and the cruising achievement rate is 70.9%. After standing for 12 hours at -20℃, the zero-100 acceleration is measured to be 3.87 seconds, and the performance achievement rate is 98.16%.
