Yesterday we tested the winter highway range of the NIO ES6 with a 100 kWh battery and we would like to share our test results with you.
Test conditions:
- Air conditioning: 22°C, 2nd wind speed
- Driving mode: Comfort mode
- Tire pressure: 2.4 bar
- Outdoor temperature: 7~4°C
We tested the ES6 Performance version, with a NEDC range of 610 km. Before the test, we fully charged the car at 1688 Longwu Road, Xuhui District, Shanghai. Then, we drove on the Shanghai-Chongqing Expressway, with the endpoint set to Xuan Cheng East Toll Station (depending on the actual range, we adjusted the turning point) and then returned in the direction of Huzhou Service Area. Throughout the journey, we used the advanced driver assistance system, set the speed at 120 km/h, and recorded the power drop and energy consumption every 10 km.
The final results are:
We drove for 335.6 km, with a displayed remaining range of 37 km, a theoretical range of 354 km, a power drop ratio of 1:1.71, and an average speed of 90.19 km/h. We finally charged the car at Huzhou Service Area. The following pictures show our driving trajectory and the recorded data.
It is worth noting that when we drove on the Shanghai-Chongqing Expressway, we had already driven 19.2 km, which means this segment of the journey was not within the highway range. At this point, the displayed range dropped by 26 km, with a power drop ratio of 1:1.35. According to this ratio, the city range can reach 452 km.
To summarize, the winter highway range of the ES6 with a 100 kWh battery is actually quite good, at around 58% of the NEDC standard. Some of the sedan models we tested couldn’t even achieve 58%, so considering the ES6’s weight and SUV drag coefficient, this result is within a reasonable range and even slightly exceeds my expectations.
In fact, there is still room for improvement in the winter highway range of any pure electric vehicle, mainly due to the impact of low temperatures, especially in cold regions of the north, and also the impact of heating from the air conditioning system, which are both industry challenges. We hope that in the near future, we can reduce the impact of low temperatures on battery range to a greater extent.
