The invention relates to an electric motor coach which comprises a coach body, a battery compartment arranged at the bottom of the coach body, a battery pack arranged in the battery compartment, a battery compartment heat dissipation air duct arranged on the coach body and comprising a coach roof outer air duct and a coach body inner air duct, the coach roof outer air duct is provided with an air inlet arranged forwards and windward, and the coach body inner air duct comprises an air supply channel section and an air exhaust channel section. The air supply channel section is communicated with the car roof outer air channel and the battery compartment, one end of the air exhaust channel section is communicated with the battery compartment, the other end of the air exhaust channel section is communicated with an air outlet, and the air outlet is formed in the bottom face or the rear side face of the car body. When the passenger car runs forwards, natural air is injected into the air duct outside the car roof through the air inlet, enters the battery compartment through the air supply channel section and then is exhausted through the air exhaust channel section, so that heat dissipation and cooling of a battery pack in the battery compartment are realized. Due to the fact that the forward speed of the vehicle can guarantee that enough air enters the heat dissipation air channel of the battery compartment, a heat dissipation fan does not need to be arranged to drive air to flow, and the internal structure can be simplified.

    本发明涉及一种电动客车,包括车体,车体底部设置电池舱,电池舱内布置电池包,在车体上设置电池舱散热风道,其包括车顶外风道和车体内风道,车顶外风道具有朝前迎风布置的进风口,车体内风道包括送风通道段和排风通道段,送风通道段连通所述车顶外风道和所述电池舱,排风通道段一端与所述电池舱连通,另一端连通有出风口,该出风口设置在所述车体底面或后侧面。在客车向前行驶时,自然风经进风口灌入车顶外风道中,并经送风通道段进入电池舱中,然后经排风通道段排出,实现对电池舱内电池包的散热冷却。由于车辆前行时的速度能够保证足够的风量进入电池舱散热风道中,不需要再设置散热风扇来驱动气体流动,从而可以简化内部结构。
