Chinese Electric Car ZhiJia R7 Dominates Winter Testing with Exceptional Range and Efficiency

In a recent winter testing event, the Chinese electric car manufacturer ZhiJia showcased its latest model, the R7, which performed exceptionally well in both high-frequency cold zones and low-temperature regions. The test results, which have now been published, highlight the car's impressive range, efficiency, and reliability, with specific details on the vehicle's performance in winter conditions.

Chilly Conditions Tests

The R7 was tested in two challenging winter scenarios: low-temperature and high-frequency cold zones. In these conditions, the electric car demonstrated its ability to endure demanding driving patterns, including 50% of its time spent at highway speeds and at an average speed of 70 ±2 km/h.

The results showed that the ZhiJia R7 achieved a range of 402.6 kilometers during low-temperature testing, with only 50.2% of the total possible range. Moreover, the car's overall efficiency in cold temperatures was found to be relatively good, achieving an average energy consumption of 24 kWh/100 km.

In terms of charging, the electric vehicle performed remarkably well under cold conditions, with electricity replenishing at a constant rate of 60 kW or higher during the initial charging stage. The entire heating test lasted only 143 minutes and 45 minutes for topping off batteries between 30-80%.

During testing, it was also observed that when the car's battery voltage fell below 50%, its core temperature would drop as low as 18°C to adjust the car to cope with cold temperatures. At 20 kilometers on the full range, only a slight temperature variation of 41.9K is noted.

Low-Temperature Zone Testing

The second testing scenario for which the data were provided was set up in low-temperature zones, where ZhiJia R7 endured an incredible drive around 702 km and achieved an even higher energy consumption average of 14.2Kwh/ 100km.

In testing the performance in a new cold zone region between Taixing city to Shanzhou road, Zhijia R7 was tested in 10 degrees Celsius. The electricity amount which replenished during that trip was 98kWh so low temperature and charging had almost zero impact on its overall efficiency.
