DD6800EV1 Electric city bus
Appearance(mm): 8040×2440×3020/3220
Rated seats:58/53
Modeling feature

“blade” front wall with eagle--eye headlamps.

The front wall consists of three parts that can be opened separately, making regular inspection and maintenance easy.

Full load-bearing structure. Unique lightweight body frame is made of the box-shaped pipes of high-strength steel and the curb weight of the coach is 7600/7900kg

There is no side door between the two axles, which not only improves the strength of the car body, but also makes a smoother and more beautiful appearance by using the stretched skin.

Separate-compartment design
The three main compartments, the passenger’s compartment, battery compartment and control compartment, are separated from each other. In case of accident, the toxic gas and flame won’t flow into the passenger’s compartment, safeguarding the passengers in a significant way.
According to relevant experiments, in the case of the new energy bus accidents where the batteries are on fire, the toxic gas from the burning batteries often cause more serious harms to the passengers than the accidents themselves. Therefore, our separate-compartment design (patent) can minimize the harm to the passengers in case of accidents.
Battery compartment layout
Easy for install, removal and maintenance of the batteries:
All power batteries are packed in five unified standard battery boxes, and connectors and inspection pots to batteries are arranged on two side walls, making maintenance and replacement of the batteries much more convenient. The centralized arrangement of batteries saves much space for chassis parts and makes the repair and maintenance of the chassis parts easier.

High anti-collision and waterproof performance:
The bottom surface of the battery is about 1600mm above the ground, and the anti-collision frame beam is installed near the rear wall side, which can greatly prevent the damage to the battery from the rear collision. The electric steering system, batteries, motor and various controllers are all highly dust and water-proof. The excellent dust and water-proof performance ensures the bus a strong wading ability and high safety under extreme conditions.
Stable and sound battery performance : With unified environment, battery box temperatures and unique thermal management system of the battery compartment, the batteries can work at the best temperature and deliver more stable performance and longer service life.
Battery pack: lithium iron phosphate batteries/ Contemporary Amperex Technology Co., Limited (CATL).
Battery capacity:138.24 kwh ( 576V240Ah )
Battery capacity:Driving range under test condition (uniform velocity method)≥250km ()
Control compartment: 6800EV1 has a very spacious rear electrical control compartment with appropriate and orderly layout of relevant control units and neat and tidy distribution of relevant cables, ensuring easy and convenient maintenance of the control units.
Driving system: the option of water-cooled permanent magnet synchronous motor + AMT gearbox is adopted, which not only gives the coach strong climbing capacity with low speed but also makes the high-speed running possible, making the coach more adaptable.
