Yutong Bus T15E: A Testament to Performance in Extremes

In the icy expanse of Finland, Yutong Bus, a leader in the international commercial vehicle market (SHA: 600066), has conducted rigorous endurance tests on its electric coach, the T15E. This groundbreaking bus endured subzero temperatures, confirming its outstanding battery performance and operational range in harsh winter conditions.

Testing in Frigid Conditions

The T15E underwent a series of trials that tested its performance at temperatures plunging to -20°C. This is not the first time Yutong has evaluated its vehicles in cold climates; previous tests included the U12 in Norway and the E18Pro in Kazakhstan. However, the results from Finland were particularly remarkable, demonstrating the T15E's robust handling of icy roads and its ability to navigate through challenging weather conditions.

Traversing a 250 km route from Oulu to Rovaniemi, the T15E effectively managed snow-covered roads, all while adhering to strict efficiency requirements for electric vehicles. Over the course of 2.5 hours, the bus exhibited remarkable battery stability, agility in turns, and competence in climbing slopes. Journalists Juho Akseli Käki and Tom Alexander Terjesen highlighted not only the vehicle's precision control but also its luxurious ride comfort, enhanced by modern suspension seating and elegant interior lighting.

Impressive Energy Management

In addition to the initial testing phase, another significant run was conducted from Oulu to Helsinki, covering a staggering distance of 609.8 km. Starting with a fully charged battery, the bus completed its journey with just 2% power remaining, achieving an impressive energy consumption rate of only 0.94 kWh/km. This marked another affirmation of the T15E’s suitability for long-distance winter travel.

Victor Wang, Yutong's product engineer, remarked on the testing outcomes, stating, "The rigorous trials in Arctic conditions with icy and snow-covered roads confirmed the reliable operations of the Yutong T15 coaches over extended routes in extreme winters." The T15E's capacity to cover over 600 km caters to diverse needs in premium long-distance bus service.

Innovative Technology Behind Success

Central to the T15E’s success is the application of advanced technology, including cutting-edge battery features boasting a high energy density of 630 kWh combined with an advanced liquid cooling and heating management system. This technology optimizes the vehicle's performance under cold conditions, ensuring efficiency and reliability.

Moreover, a synchronous motor with permanent magnets achieves peak performance of up to 97.5%. Yutong also integrated innovative functions like a proprietary energy recovery system during braking and a low-temperature heat pump for enhanced climate control, which contribute significantly to energy savings.

Equipped with megawatt fast-charging capabilities — compatible with standard charging stations across Europe — the T15E can be fully charged in just over one hour, ensuring maximum convenience for passengers and operators alike. Additionally, the integration of advanced safety systems, including EBS, ESP, and LDWS, further elevates the reliability and effectiveness of the vehicle for long-haul transport.

The testing of the Yutong Bus T15E in Finland showcases not only the advancements in electric transportation technologies but also sets a benchmark for energy-efficient solutions that perform exceptionally well in challenging environments.
