Yutong T15E Electric Bus Shines in Extreme Cold Tests

The Yutong Bus Company has recently demonstrated the exceptional performance of its T15E model electric bus under severe winter conditions in Finland. This testing follows significant evaluations previously done in Norway and Kazakhstan, each aimed at pushing the boundaries of what electric buses can achieve in challenging environments.

During the rigorous trials set in frigid temperatures as low as -20 degrees Celsius, the T15E effectively maneuvered treacherous icy roads, proving its reliability, energy efficiency, and performance in real-world scenarios. The tests were structured to explore the bus's capacity regarding safety, energy consumption, range, cornering ability, and hill-climbing in extreme settings.

One of the highlight tests took the T15E on a twisting 250-kilometer route from Oulu to Rovaniemi, where it maintained remarkable energy management throughout a two-and-a-half-hour journey. The T15E outperformed expectations, demonstrating outstanding battery efficiency, stability on inclines, and precision in handling, garnering positive feedback from media representatives Juho Akseli Käki and Tom Alexander Terjesen. They highlighted the vehicle's superior maneuverability and luxurious ride comfort, complemented by advanced suspension seating and elegantly designed ambient lighting within the interior.

In another test, the T15E completed a grueling journey of 609.8 kilometers from Oulu to Helsinki, again under -20 °C conditions. Despite the demanding temperatures, the bus accomplished the trip with only 2% battery remaining, achieving a remarkably low energy consumption rate of just 0.94 kWh/km. This outcome underscores the T15E's capabilities in harsh winter climates.

Victor Wang, a product engineer with Yutong Bus, stated, "In challenging conditions of ice and snow, the Yutong T15E has shown it can maintain stable performance while achieving maximum range in extremely cold environments." He emphasized that a range exceeding 600 kilometers caters to the diverse needs of long-distance transportation services with a focus on passenger comfort and safety.

The extraordinary performance of the T15E is attributed to its next-generation battery, which boasts high energy density paired with a 630 kWh capacity. This is further supported by an advanced cooling and heating management system that optimizes efficiency at lower temperatures, enabling the bus to operate effectively in winter conditions. The permanent magnet synchronous motor achieves peak efficiency levels of up to 97.5%.

Moreover, the T15E includes innovative features such as an efficient energy recuperation system developed by Yutong and an AC system with a low-temperature heat pump, further enhancing its energy-saving capabilities and operational reliability. Additionally, the bus supports megawatt-level fast charging, allowing it to recharge fully in just over one hour and ensuring compatibility with existing charging stations across Europe, thus providing operators with utmost convenience.

In terms of safety, the T15E is fitted with advanced technologies, including an electronic braking system (EBS), electronic stability program (ESP), and lane departure warning system (LDWS), all of which contribute to a reliable and effective long-distance transportation performance.

With these impressive attributes and successful trial outcomes, the Yutong T15E not only sets a benchmark for electric buses in cold climates but also highlights the future of sustainable public transportation.

Conclusion

In conclusion, Yutong's T15E electric bus has proven its mettle in extreme weather conditions, setting a new standard for electric buses globally. This groundbreaking achievement marks a significant step towards enhancing public transportation's sustainability, efficiency, and reliability.
