A bodywork structure for controlling or modifying the temperature of a passenger compartment of an electric or hybrid motor vehicle is provided. The bodywork structure includes at least one interior and exterior panel and one intermediate layer between the panels, each panel being based on a thermally conducting and electrically insulating material. The intermediate layer has at least one phase change material PCM and electric components coupled to it and is configured to be connected to an accumulator battery and which are able to convert the electrical energy available when the battery is being recharged into thermal energy stored by the PCM, so that the stored thermal energy is then transmitted to the interior of the vehicle when the latter is in use thanks to crystallizing of the at least one PCM, which is conversely able, by melting, to absorb an excess of heat inside the vehicle when this PCM is not recharged.
