On December 17, a “super long live broadcast” lasting over 14 hours attracted attention. NIO founder, chairman, and CEO William Li drove the ET7 from Shanghai, testing the 150kWh ultra-long range battery pack’s range. After over 14 hours of driving, Li finally reached the Longjue East Service Area in Xiamen from Shanghai, achieving a record of 1044 kilometers on a single battery.
According to reports, the average energy consumption for every 100 kilometers of the 1044-kilometer test is 13.2kWh, with 3% of the battery remaining, and it is expected to still be able to drive for more than 30 kilometers. Li Bin stated that the 150-degree ultra-long-range battery pack carried with the vehicle this time is the world’s first CTP battery pack without thermal runaway, with a cell energy density of up to 360Wh/kg, making it the highest energy density and highest energy density power battery pack in China. It should be noted that low temperature has always been a major killer of electric vehicle range. In winter, the range is reduced, the battery charging speed slows down, and the power consumption of the air conditioning heating system is high. When new energy vehicles are in a low temperature environment, the battery capacity and driving consumption will accelerate the decline. The outdoor temperature during Li Bin’s live broadcast this time was below 10 degrees, which has a certain reference value. It is reported that the NIO 150-degree battery pack was released at NIO Day in 2021. During the live broadcast, Li Bin stated that the NIO 150-degree battery pack is the most advanced in the world among mass-produced battery packs, and the announcement and testing of the vehicle model have been completed. It will soon enter the production stage and be delivered to users in the near future.
According to NIO, the ultra-long battery pack tested this time can be adapted to all models of NIO’s first and second generation platforms, which means it can support battery swapping. However, NIO President Qin Lihong once revealed that the cost of this battery pack is very high, equivalent to the cost of a NIO ET5. Therefore, the large-scale commercial use of this battery pack may still take some time. However, NIO currently provides battery rental services, allowing users to “pay by the day” to rent a 150kWh battery pack when they have long-distance needs, and then switch back to a regular battery pack when the need is over.
