Ac For Bus Factory leverages three core advantages—full-industry chain integration, deep customization, and rapid technological iteration—to create a differentiated competitive advantage in the global market, particularly excelling in modular production, extreme environment adaptability, and cost control.
Chinese manufacturers, leveraging their domestic bus manufacturing advantages, have risen rapidly, with SONGZ and BUSCLIMA being typical examples.
Ac For Bus Factory has achieved extreme environment resistance covering a full temperature range of -40℃ to 60℃. Through material innovation, system redundancy design, and intelligent thermal management technology, it has achieved stable operation in scenarios such as the high-temperature desert of Qatar and the extreme cold of Mohe, China, with core performance indicators reaching international leading levels.

I. High-Temperature Environment Resistance (40℃~60℃)
1. Enhanced High-Temperature Efficiency of the Cooling System
Ac For Bus Factory’s high-temperature version of the pure electric air conditioner, customized for Qatar, can maintain the interior temperature at 22℃ even when the ambient temperature is 50℃. By using an air curtain to prevent hot air intrusion, its cooling capacity is increased by 20% compared to the conventional version.
In a ground temperature test at 81℃ in Turpan, the pure electric bus, employing full liquid cooling and third-generation SiC semiconductor technology, achieved uninterrupted operation of the air conditioning system at 60℃. After being exposed to direct sunlight, the cabin temperature dropped from 60℃ to a comfortable range in a very short time.
2. Upgraded Protection for Key Components
Battery Thermal Management System is the core of high-temperature resistance. A patented liquid cooling system and nitrogen safety protection device ensure that the battery’s maximum temperature does not exceed 45℃, reducing capacity degradation by 10% over its entire lifespan.
BYD batteries, combined with CTC chassis integrated technology, stabilize the battery temperature within a safe range of 40℃. The motor is equipped with a mud and sand protection structure, allowing it to operate freely in sandy environments.
Breakthrough in Intelligent Thermal Management Technology
1. Dynamic Load Adaptation
The bus’s air conditioning system is equipped with a dual-core MCU controller that uses AI algorithms to predict changes in ambient temperature. For example, it detects when the vehicle enters a tunnel and reduces cooling power by 15% in advance, reducing energy waste. BYD monitors battery status 24/7 through its BMS system, dynamically adjusting heating strategies to balance heating rate and power consumption, achieving an 18% reduction in heating energy consumption at -30℃.
2. Full-Scenario Verification System
Manufacturers have established multi-level testing systems from laboratories to real-world environments: Yutong has equipped its Zhengzhou base with a -40℃~60℃ environmental simulation chamber, randomly selecting one unit from every 100 products for full-condition cyclic testing; BYD, Geely, and other companies conduct on-site verifications annually in Turpan (surface temperature 81℃) during summer and Mohe (-30℃) during winter, ensuring that the performance degradation of the air conditioning system is ≤8% under extreme temperature differences.
From high-temperature vehicles used in the Qatar World Cup to buses operating in the frigid regions of Northern Europe, Ac For Bus Factory has formed a three-in-one extreme environment solution integrating materials, systems, and algorithms. This resilience has not only supported the global expansion of companies like Yutong and BYD, but also extended the comfort experience to the most demanding climate zones on Earth through technologies such as liquid cooling and intelligent forecasting, while traditional air conditioners “go on strike” at 45°C due to outdoor unit shutdown.
