Studies indicate that by 2030 there will be over 40 megacities with ten or more million inhabitants. More people in a confined area also means more cars and therefore more air pollution. Given this situation, Lion decided to develop sustainable mass transportation solutions. There are two main aspects that must be considered here, as Raphael Oullet, Product Designer at Lion, explains: "First, in the case of a battery-powered vehicle, a subsystem analysis is required to have a precise view on how the drive cycles and charging scenarios would affect the battery’s performance. Then the appropriate thermal management solutions must be identified to determine the optimal balance between heating and cooling loops. Secondly, from early development at vehicle level, we must be able to estimate the overall vehicle performance. The realistic range can be determined using real drive cycles."
