Description

Technical Field

[0002] With the development of national urban road construction and new energy vehicle technology, the country has also issued a series of policies and regulations to promote the accelerated development of new energy sanitation vehicles. Now, pure electric sanitation vehicles account for an increasing proportion of sanitation vehicles.

[0003] Compared with ordinary pure electric vehicles, pure electric sanitation vehicles have an additional upper operating system, which will also consume power from the power battery when in operation. If the calculation of the driving range of pure electric sanitation vehicles is like that of ordinary pure electric vehicles, which only considers the chassis system without considering the upper operating system, or cannot consider both the chassis system and the upper operating system at the same time, the calculation error of the vehicle's driving range will be large.

[0004] However, the existing pure electric sanitation vehicles consume electricity only when they are in operation. They do not consume electricity when they are driving normally. The mileage display is relatively complicated, and it is difficult to intuitively feedback the actual mileage status of the vehicle to the driver. Utility Model Content
