The structure design of mobile charging piles

Abstract

The simple instalment of mobile charging piles benefits for its convenient layout, while dynamic arrangements of those charging piles through mobile mode make up for the insufficient number of fixed charging piles, which meets the growing charging demand under the increasing popularity of electric vehicles. According to the application requirements of mobile charging piles, CATIA software was used to model the structure, of which strength and reliability were analysed under four load conditions. Our results have demonstrated that the maximum deformation value of the structure is 3.07 mm, and the maximum stress is 134.41 MPa, which is within the safety range of the selected materials. In addition, the gravity centre of the charging pile is located at the bottom of the structure, and thus the stability meets the requirements. Taken together, our research provided a beneficial reference for future engineering practice.

“…The research on modeling design of charging pile were as follows: Pro/E (Professional Engineer), CAD (Computer Aided Design), and 3Ds max software were used to complete the modeling design of a new type of charging pile [18]; modeling design of curved surface shell coated with nano paint and modeling design of square surface shell coated with traditional paint were conducted [19]. The research on the application test of charging pile were as follows: According to the application requirements of mobile charging piles, CATIA (Computer-Aided Three-Dimensional Interactive Application) software was used to model the structure, of which strength and reliability were analyzed under four load conditions [20]; a simulation testing platform for charging pile control system based on semi-physical simulation technology was developed [21]. The research on charging technology were as follows: A combination of diagnosis methodologies applied on large-size pouch Libs from a dismantled first-generation Nissan Leaf retired battery pack was presented, cycled with different accelerated ageing cycling procedures [22]; a charging method using multi-stage constant current was proposed and the charging time, charging capacity, and temperature increase in the battery were optimized by multi-objective particle swarm optimization algorithm [23]; the MPPT (Maximum Power Point) algorithm was applied to the charging control system and the voltage energy consumption of the charging circuit was precisely controlled [24].…”
