Haval Star 1.5L Pure Electric Makes Historic Debut in Double Winter Testing

The test portion of the Hualu Car Super Test 2024 for new energy has been completed, and here is a detailed analysis of the Star 1.5L pure electric vehicle's performance.

This year's new energy challenges were set up in two regions: Beijing-Hebei and Inner Mongolia, covering the vast majority of winter temperatures in China. The testing grounds represented winter use scenarios for major battery-electric auto owners in China, focusing on power consumption, charging, and energy density, as well as comfort and reliability across five dimensions.

The test vehicle used was Haval Star 1.5L, equipped with a 1.5 liter four-cylinder natural combustion engine and an electric motor with the maximum power of 150kW, and driven by a front-engine, front-wheeled layout configuration. The battery capacity is 20.5 kWh, and the WLTC range test achieved a pure electric cruising distance of 105km.

Hypothermic Zone:

In the hypothermia area test, at temperatures ranging from -20 °C to -15 °C on January 18th, Haval Star 1.5L participated in a round trip challenge in the Baarag Nuuruu cold blood Valley of the Heilongjiang province to Chabarsa River valley. After completing 50% of the high-speed route and 50% of low-speed routes, the Star 1.5L achieved an electric-only cruise distance of 92.1km with a charging rate of 87.7%.

The car resumed electric mode after being refueled with R92 gasoline for 110 kilometers, consuming approximately 5.95 liters per 100 kilometers.

After static testing for 60 minutes to ensure the car reached below-zero temperatures, it began re-charge using a 120 kW high-power charging station, and took 151 minutes from 10% state of charge (SOC) increased to 100%. High-speed replenishment occurred at peak power level when SOC is between 30% and 80%.

According to 19.182 kWh total electricity in, the Star 1.5L consumes approximately 20.833kWh per 100 kilometers for electric vehicle operation.

During a comfort assessment of the hypothermic zone test, during long-distance driving, an appropriate temperature was maintained consistently throughout the entire driving period with no wind resistance or any feeling of excessive heat generated by cooling.

Cold Zone:

In low-temperature regions, temperatures fluctuated between -5 °C and 15 °C. Test vehicle Haval Star 1.5L for winter tests set out from the city of Baoding to Tianjin via a round-trip route using 50% highway traffic and 50% low-speed traffic routes. During this test stage, achieved electric-only driving distance for Haval Star 1.5L reaches 126.5km with a high-rate of 120.5%, ranked first among competitors.

Using R92 gasoline for an additional 106 kilometers after completing the low-temperature charging route, with a reduction in fuel consumption from approximately 4.68 liters per hundred kilometers in the hypothermic zone compared to 5.95 liters in lower temperatures.

A 120 kW stationary high-power recharging station was used in this part of the testing course with an estimated time increase using electricity as well charging power for the higher value, at peak stage below 25Kw.

Finally, after charging up all power capacities from low temperature range, the Haval Star had a power consumption density rate lower than competitors, also experienced smooth performance and no issue with car overheating by virtue of sufficient air-cooled capacity.

Summary

Haval Star in double winter zones testing demonstrated its advantages in energy consumption, reliability, comfort as well as achieving high success rates on various electric driving tests.
