Huanghai DD6851EV5 Electric city coach adopts "blade" front wall, full load-bearing structure, lightweight design and Huanghai self-developed bus chassis. The adoption of the permanent magnet motor, lithium-ion battery and vehicle intelligent thermal management system reflects the concept of energy saving and environmental protection. The separation of passenger’s compartment, battery compartment and control compartment ensures driving safety. Long wheelbase and short front & rear overhang structure give the coach a larger interior space and stronger loading capacity. The intelligent remote monitoring system realizes the whole-life-cycle safety management of the coach.
