Structure arrangement of pure electric light bus

Abstract

The invention relates to a structure arrangement of a pure electric light bus. Refitting is carried out on the three type chassis of the light bus of Sprinter. An engine and accessories attached to an original bus chassis, a cooling system, a fuel system and a speed changing box are removed; a gearing apparatus matched with an electronic control system and instruments are replaced; a vehicle controller, a drive motor, a motor controller, a power battery pack, battery control systems, a high-voltage distribution box, a vehicle-mounted charger, a water pump, a power steering pump, a brake booster pump and the like are added. The structure arrangement of the pure electric light bus fully utilizes the limited space of the refitted bus model, an electrical control system is arranged in an engine cabin, the classified arrangement is performed, and efficient waterproof, dustproof and tamper-proof requirement is met; the drive motor is arranged beneath a cab, the reasonable arrangement is realized on the premise of meeting national technical standards, and the requirements for waterproofness, dust prevention, anti-collision and heat dissipation of the motor are fully taken into consideration; the requirements for high capacity, high utility rate of space and expandability are fully considered as to the design of battery boxes, and the requests of national technical standards are met.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a structural arrangement of a pure electric light passenger car. Background technique [0002] As global environmental problems and energy crises continue to emerge, the development of new energy electric vehicles has become the consensus of all countries in the world. The current battery motor installation of pure electric vehicles cannot effectively use the space, resulting in limited battery storage capacity and low mileage. The installation position of the pure electric three-electric control system is unreasonable, prone to moisture, poor heat dissipation, and mutual interference of line signals. And if the arrangement of the electrical components is not reasonable, it is easy to cause the signals generated by each device to interfere with each other, the heat dissipation of the equipment is not good, the lack of ventilation is easy to accumulate dust, and it ...

[0002] As global environmental problems and energy crises continue to emerge, the development of new energy electric vehicles has become the consensus of all countries in the world. The current battery motor installation of pure electric vehicles cannot effectively use the space, resulting in limited battery storage capacity and low mileage. The installation position of the pure electric three-electric control system is unreasonable, prone to moisture, poor heat dissipation, and mutual interference of line signals.

Moreover, if the arrangement of the electrical components is unreasonable, it is easy to cause the signals generated by each device to interfere with each other, the heat dissipation of the device is not good, the lack of ventilation is easy to accumulate dust, and it is easy to be damp and short-circuited.
