Abstract: The purpose of this paper is to study the power battery matching of new energy pure electric vehicles. Based on the pure electric mixer, the matching method of power battery is studied by establishing the working characteristic model of mixer. The research results are fully consistent with the daily working characteristics of pure electric mixer, and the power battery power can also meet the demand of full cycle use, which is consistent with the field research results of pure electric mixer. This conclusion can provide a certain reference for the research and development of pure electric vehicles. At the same time, the modeling method of mixing vehicle working characteristics in this paper can be used to study the power battery matching of other fixed application scenarios, so as to contribute to the development of pure electric vehicles and energy conservation and emission reduction.
