Electric commercial vehicles (EVs) often face serious challenges in extreme summer conditions — from battery degradation to reduced driving range and slower charging speeds. To address these real-world concerns, Wuling, in collaboration with the China Automotive Technology & Research Center (CATARC), became the first in the industry to complete six rigorous high-temperature tests in Turpan, Xinjiang — known as one of the hottest places on Earth.
Models like the Wuling Yangguang and Wuling Hongguang EV successfully endured high-temperature endurance, steep slope climbs, water immersion, and battery scrape tests, setting a new technical benchmark for the global electric commercial vehicle industry.
Two Industry-Leading Combined Tests
High-Temperature Load Endurance + High-Temperature Fast Charging
In a 47°C environment with a full 1-ton load, the Wuling Yangguang EV maintained a remarkable 86.8% range retention rate even under power-limiting conditions, consuming 90% of its battery capacity.
Immediately after, it entered a high-temperature fast-charging test, charging from 30% to 80% state of charge (SOC) in just 29 minutes and 36 seconds. This validates the vehicle’s ability to operate reliably under intense delivery schedules and high-load conditions.
High-Temperature Slope Climb + Water Immersion & Battery Scrape
In a dry, sandy environment, the Wuling Hongguang EV conquered 36% and 42% unpaved slopes, followed by a combined 300mm deep water immersion and battery scrape test.
The obstacle height exceeded the battery pack’s bottom surface by 30mm, yet after the test, the battery voltage, temperature, and insulation remained normal — proving exceptional safety and durability.
Four More Extreme Challenges
High-Temperature Range Stability
At 43°C under direct sunlight, the Wuling EVs equipped with the Shenlian Commercial Battery achieved over 90% range retention, allowing operators to maintain near-normal range without frequent charging — boosting delivery efficiency in hot climates.
Steep Slope Performance
On a 37% cement slope, the test vehicles climbed with ease, ensuring stable power for businesses operating in mountainous or construction areas.
High-Temperature Fast Charging
Even after two hours of heat exposure at 46°C, the Wuling Yangguang 300KM model charged from 30% to 80% SOC in just 30 minutes — the same performance as in normal temperatures.
Rapid Cabin Cooling
In a cabin heated to 61.7°C, the Wuling Hongguang EV’s air conditioning system quickly cooled the interior, successfully passing CATARC’s commercial vehicle comfort test.
Shenlian Commercial Battery: The Core Technology Behind the Success
The Shenlian Commercial Battery is the heart of Wuling’s high-temperature performance. With 3 million units sold and zero thermal runaway incidents, it has become the best-selling EV commercial battery in China — installed in 1 out of every 4 new energy commercial vehicles.
Key technological advantages include:
IP68 water resistance
Over 4,000 charge cycles lifespan
2,000+ extreme safety tests ensuring “no fire, no explosion” standards
MUST integrated structure reducing maintenance costs by over 90%
Feiliu smart thermal management for precise temperature control in extreme heat
Why This Matters for the Global Commercial EV Market
Many commercial EVs struggle with performance in extreme weather, causing downtime, higher operating costs, and safety risks. Wuling’s CATARC-certified summer testing fills a critical gap in high-temperature reliability standards for electric commercial vehicles.
By delivering peace of mind, faster charging, and better durability, Wuling sets a global benchmark for performance in hot climates — making it an ideal solution for logistics, urban deliveries, and rural transport in regions such as Africa, the Middle East, and Central Asia.
Conclusion
The Turpan summer tests prove that Wuling’s electric commercial vehicles are not only affordable but also built to handle the toughest conditions on Earth. With advanced battery technology, exceptional safety, and outstanding performance in extreme heat, Wuling continues to lead the way in the global commercial EV industry.
