ZHENGZHOU, China, Sept. 2, 2021 /PRNewswire=KYODO JBN/ --

- Equipped with multiple patented technologies, Yutong YESS is set to bring the

EV safety standard to the next level.

On August 31st, Yutong Power Battery Safety Protection Standard Conference &

Power Battery Safety Test was streamed live worldwide, unveiling its latest EV

bus safety technology, the YESS - Yutong Electric & Battery Safety Protection

Standards. It will be the world's first EV safety technology to be applied in

batches on commercial vehicles.

YESS offers 5 layers of protections– whole-vehicle security, system security,

box security, component security and monitoring security, realizing 3 major

improvements on safety level, all-weather capability and road adaptability.

Researches suggested that over 30% of EV battery failures were caused by

external damages. Therefore, instead of just protecting the battery, YESS

covers the whole vehicle and uses a "Cage type" structure to surround the

battery with a high-strength fence to cushion such collisions.

As for internal failures like ISC and TR, the system security of YESS applies

an industry first nitrogen protection technology to completely cut off the

oxygen in the battery box to avoid combustion.

When it comes to the separation of external and internal safety hazards, the

box security of YESS ensures a multi-layered thermal-electrical coupling

protection.

The component security comes in handy under extreme conditions like high

voltage. It adapts the commercial-vehicle-suitable multi-package liquid thermal

technology to build a heating-parts-free battery box.

YESS is also about real-time monitoring. It provides an all-time, all-fields

monitor over the battery conditions, and a mobile app to enable the intelligent

cloud management.

Confident in this technology, Yutong conducted a battery safety test show

during the live stream, putting the YESS-equipped battery pack under extreme

test conditions of overheating and overcharging to prove its safety and

stability.

Stepping into the field of new energy vehicles in 2008, Yutong has sold over

150,000 units worldwide with the total operating mileage reaching

24,800,000,000km. Determined to mitigate the concerns over EV safety, Yutong

has shifted the battery safety into the next gear with YESS – an all-around

integrated safety solution that focuses on the whole vehicle as a completed

system.

Yutong is determined to continue upgrading its technology and updating YESS to

guard passengers' every journey on Yutong EV buses with safety, sustainability

and comfortability.
