Features
DD6110KEV4 electric express bus is 10.8-meter multi-functional car for group passengers. It is featured by the following characteristics:

1. Full loadable automotive body structure
1) Full loadable automotive body structure enables every part of the entire automotive under stress to enhance the vehicle force strength, reduce vehicle weight and improve the effective output power.
2) Low center of gravity ensures stable and safe running of the vehicle.

2. Strong power and excellent power performance
1) The express bus is suitable for driving on a variety of road conditions. It features strong driving force, faster speeding up, low noise and stable performance.
2) Speed reduction function of the drive motor reduces wear of brake shoe.
3) When driving on the snowy or wet road, driver can manually remove the function to improve the safety of the brake.

3. The layout of the three-layer battery maximizes the car trunk volume and ensures that the height inside the car is about 1930mm
The engine of Huanghai Bus's electric vehicle is smaller than the conventional engine. The wheelbase is 550mm longer than same type of car, so that it allows layout of two trunks in the car.

4. The battery adopts high-energy density CATL lithium iron phosphate battery and it has a long service life cycle.
1) The service life of battery pack is up to 8 years. Service life cycle in room temperature is more than 6000 times. The battery pack can be stored more than 15 years;
2) 2.IP67 level dustproof and waterproof;
3) The battery in -30 1 ℃ alpine regions can achieve natural temperature drop of 1 ℃ in 60 minutes to ensure that excellent charge and discharge performance battery system in alpine region.

5. Four specifications of power battery matching mode are optional according to the user requirements for driving mileage and driving conditions.

6. Electrical power steering technology (HEPS) :
1) Dual power supply HEPS realizes the protection level of IP67.
2) Using permanent magnet brushless motor, HEPS features small size and high efficiency. Permanent magnet synchronous motor carries out electronic power steering to effective save en 75% energy.
