Abstract. The development of electric transport is inextricably linked with the modernization of the associated infrastructure, and one of the factors for the slow introduction of electric transport in Russia is the small number of charging stations. But most of the existing solutions in the field of charging stations have a drawback – the lack of mobile installations. The team of Kazan State Power Engineering University (KSPEU) and Production Association "Zarnitsa" is developing a mobile electric vehicle charge units (MSCEU). At the design stage, a problem has arisen with the fact that it would be difficult to conduct constant tests on a full-fledged prototype of the MSCEU due to the weight and size parameters of the equipment. At the same time, there is a need for preliminary confirmation of the compliance of the MSCEU with the climatic (UHL1) and mechanical performance (M3) groups. To accomplish this task, it was decided to simulate the work of the MSCEU in the COMSOL software. For solving this problem, it is necessary to simulate a module of four rechargeable batteries in order to confirm the manufacturer's parameters, and thus verify the resulting model. Based on these results, a complete MSCEU model consisting of 1,200 batteries can be implemented, which can be used to check compliance with the given conditions. For thermal calculations, it is necessary to check the pre-selected parameters of the air conditioning power, and to select the thickness of the thermal insulation. As a result a 3D model has been implemented in COMSOL, the parameters of all materials used have been determined, the connections of solutions have been built, physics of processes and the type of a solver have been selected. Based on the simulation, the insulation thickness has been chosen, the results of simulation of operating the air conditioning system to maintain the operating temperature of the batteries have been obtained, and the results have been demonstrated that confirm the mechanical reliability of the MSCEU.
