3S Safety Technology
Yutong has systematically summarized the technical safety requirements of new energy buses in various operating environments, and proposed "3S Safety Technologies", which is the latest safety technology of Yutong new energy buses. In order to achieve the three safety goals of “water resistance, fire resistance and electric shock resistance” of the "3S Safety Technologies", Yutong has deeply studied the material safety, sealing safety and structural safety technologies, and established the safety solutions regarding development & manufacturing, transportation & storage, usage & maintenance, operation & monitoring, etc., comprehensively enhancing the overall safety level of electric buses.
-
Water resistance
The protection level of the full electric powertrain system meets IP68 requirements and the fording depth of whole vehicles reaches 500mm.
-
Fire resistance
Buffer spaces for high-voltage electrical components are reserved at the front and rear of the vehicle. Furthermore, the anti-crash structure of vehicle body is enhanced and the high-voltage parts will not be out of function after being collided. High flame retardant grade materials are adopted for the parts of full electric powertrain assemblies. Fully spatial and thermal isolation between battery cabin and passenger compartment poses no threat to passengers even if the batteries catch fire.
-
Electric shock resistance
No bare wires, terminals or connecting units; Live parts of power circuit system are designed to prevent direct contact; Real-time monitoring system of insulation resistance can trigger visual and acoustic alarm and automatically cut off the power when the insulation resistance value is lower than the warning line.
-
Battery safety
The batteries have gone through a series of destructive tests such as high temperature, short circuit, squeeze, soak, overcharge, puncture, etc. The battery management system (BMS) can monitor the temperature, voltage, current and electric quantity of each cell, and also has corresponding warning functions.
-
Recharging safety
Compared to AC recharging, the DC recharging way used by Yutong is much safer, since it is isolated from the grid, and meanwhile has the active and passive protection mechanisms. The max. leakage current of DC recharging is 10mA while the max. leakage current of AC recharging can reach high up to 30mA.
-
Safety monitoring
Through monitoring the key components, the functions like safety accident prevention, battery life prediction, fault classification warning and so on can be achieved.
Yutong Electric & Battery Safety
Protection Standards
Five Protection Systems
Vehicle Protection
High strength anti-collision fences, enhance the collision standard comprehensively and build an "Impregnable Wall" for batteries.
System Protection
24/7 all time and area monitoring nitrogen protection and real-time oxygen isolation in the battery pack, really "Pull the Plug" on problems .
Pack Protection
Multiple level thermal-electric coupling protection achieves effective isolation of internal and external safety hazards and creates a “moat" for batteries.
Parts Protection
High efficient liquid heating technology with multiple-packs and elimination of HV heating components in the box keeps the batteries away from “Igniter" thoroughly.
Monitoring Protection
24/7 all time and area battery monitoring system ensures the battery safety always in control anytime and anywhere.

Operation case
Mexico City, Mexico
In November 2019, Yutong dual-powered trolleybuses began to operate on the Central Avenue of Mexico City, and so far their total mileages have exceeded over 25,000 kilometers.
In 2020, Mexico took the lead in introducing Yutong's 18 meters dual-powered trolley bus, setting a benchmark for the updating and promotion of dual-powered trolley bus in Latin America and the world.
Nur , Kazakhstan
In Nursultan, capital of Kazakhstan, the operation of 590 CNG buses will greatly improve the local public transport condition. Meanwhile, these clean energy vehicles will also effectively reduce the air pollution.
Copenhagen, Denmark
E12 has been applied in Danish market for more than two years. The performance of the vehicle has been fully verified, and the product quality has been highly praised by customers.
Santiago, Chile
In January 2018, Yutong's 12-meter low-floor full electric city bus conducted trial operation on the Route 315e in Santiago.
Bulgaria
In 2018, Yutong E12 conducted a trial operation in Bulgaria, which was the first full electric bus in the country. In the same year, a batch of Yutong full electric buses were put into operation in France.
Moscow, Russia
In July 2017, Yutong's 12-meter full electric bus conducted trial operation in the downtown of Moscow. The total mileage has reached 5,925km without problems.
UK
In 2017, a Yutong 12-meter full electric bus conducted trial operation in Liverpool, Manchester and Cambridge for one year with a fault-free record, and the total mileage reached more than 15,000km.
Sofia, Bulgaria
In January 2017, Yutong's 12-meter full electric bus conducted trial operation in Sofia. When the outside temperature is -20~25℃, the temperature inside the vehicle can be maintained at 19℃. The power consumption is quite low, and the driving range can reach 300km after being fully charged.
Macau, China
In 2017, five units of Yutong ZK6109BEVHA full electric coaches successively conducted trial operation in six gaming companies in Macau. In the high temperature environment of 30-35°C and with the air-conditioning temperature at 19°C, the power consumptions of these vehicles were excellent. After being fully charged, the vehicle can meet the 16-hour operation requirement.
Yutong full electric bus appeared on UN Climate Change Conference 2015
Paris, France
In February of 2016, Yutong 12-meter full electric bus conducted trial run on Route 21 and 147 in Paris, France and the average speed is 8km/h on Route 21. The driving range of the bus can meet one-day operation requirement while the air conditioner is turned on and the route is congested.
