Abstract: In recent years,China's new energy vehicles have developed rapidly. As a key subdivision product, environmental sanitation vehicles are very little affected by the subsidy recession, and their market penetration is increasing year by year. 3 752 new energy environmental sanitation vehicles have been sold in 2021. It is expected that the market will grow rapidly in the next 3～5 years. This paper taking a pure electric sanitation vehicle as an example, according to the four indicators of power and economy, through theoretical analysis and simulation calculation, selects the power chain system parameters firstly, then combining with the real vehicle road spectrum collection, and then establishing the simulation model of three technical routes based on Cruise software, verifies the power and economy of multiple power chain configuration, finally, through comprehensive analysis of power, economy, cost and competing products, determines the optimal power chain configuration combination. The paper can provide reference for the design of power chain of similar pure electric special vehicle products, and has a certain guiding role.
