Yutong Electric Architecture
Seamless Integration, Superior Efficiency
Yutong Electric Architecture maximises performances with fully integrated systems
Yutong’s YEA is a fully integrated system where every component works together seamlessly from the start. This level of integration ensures that your bus operates with unmatched efficiency and reliability. With YEA, you get the confidence that comes from a bus designed to perform as a unified whole.
What is YEA?
Yutong Electric Architecture developed by Yutong, is the first EV specific platform that integrates software and hardware in the CV industry, opening a new era of hardware integration and software OTA upgrades.
Starting with the brains of the vehicle, the VCU (Vehicle Control Unit). Made in house at Yutong, this unit was specially designed to work in series with all vehicle systems. By taking into account vehicle conditions and driver input, the VCU can control all aspects of the vehicle.
The muscle of the vehicle, the Power Control Unit, takes commands from the VCU and the ICU (Integrated Control Unit) to control the HV power of the vehicle and run all HV systems. This is not just a big relay box, the technology within the unit significantly affects the vehicle’s efficiency.
The ICU house the IGBT inverter circuit this is the unit that coverts the DC to AC and is specialised to the Yutong product and has the largest effect on the efficiency within the unit.

Real World Experience
Yutong’s extensive R&D and real-world experience with over 180,000 new energy vehicles worldwide, has given them the knowledge that a fully integrated vehicle system is far more efficient and reliable in real world situations.
Yutong buses are designed to integrally work together, rather than a traditional chassis and third party supplied body. So with all these systems taken into account Yutong YEA ensures that all vehicle system are fully integrated and communicate with each other to proven the best reliability and efficiency of the vehicle.
Safe, Reliable, All-Round Protection
As a leader of new energy buses, Yutong has independently developed the new energy technology, “YEA”, and formulated the safety technology standard for electric buses, Yutong Electric Safety Standard (YESS), covering fire prevention, waterproofing, and electric shock prevention. The safety level reaches IP68+IP6K9K, which is the highest in the industry, meeting the requirements of European standards and ensures the safe operation of vehicles in all aspects.
