For the sake of full electric vehicle safety, we have gone farther than before

Improving the safety of vehicles has become our most important and consistent pursuit. We have accumulated rich experience and made a lot of breakthroughs regarding the safety technologies of conventional vehicles, and successfully applied them to our products. Nowadays, in order to improve the safety of full electric vehicles, we should do a better job and go farther than we did before.

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.

Three Improvements

  • Security Level Upgrade

    Experienced 83 Strict Safety Tests, of Which 48 Items are Stricter National Standard; All Battery Units Fully Meet The EU ECE R100 Safety Test Standard.

  • All-climate Capability Enhancement

    Wide Operation Range -40℃~55℃

  • Road-conditions Adaptability Improvement

    Deserts, Ice Fields, Basins and Mountains,Stable Operation Worldwide.
