| Popis: | International audience; In order to reduce the greenhouse gas emissions of vehicules, electric vehicles meet an increasing success. However, a key obstacle is the autonomy of their batteries. The integration of photovoltaic modules in car parts (VIPV: Vehicle Integrated PhotoVoltaics) is a relevant solution to minimize the battery size or provide power for the additional equipment. This solution is already being studied by car manufacturers like Toyota (Prius), Sono Motors (Sion), Lightyear (One) ... These manufacturers mostly use materials and processes traditionally used in the PV industry: glass and polymers for the materials and lamination for the process of integration of PV cells. However, this process is not well adapted for the automotive industry. Moreover, glass or polymer panels do not enable to minimize the weight of the vehicle and do not meet the mechanical constraints imposed by automotive standards for parts such as doors or bonnets.In 2019, the CEA revealed its first work on an electric vehicle assisted by solar energy, the CZen. This opened the way for an in-depth work on VIPV. Thus, the aim of this study lead together with the technical center IPC is to develop manufacturing processes for the integration of PV cells adapted to the automotive industry: Resin Transfer Molding and thermocompression. The materials used, glass fibre composites, are also yet not common in the PV industry. The index case is a 40 cm*40 cm panel with a double curvature. The main aspects of this study concern:- the choice of materials adapted for photovoltaic constraints, particularly with regard to transparency and ageing of the materials (norm IEC 61215);- the choice of materials and stacks adapted for the processes, especially in terms of permeability and impregnation of fibres;- the identification and selection of the parameters for the processes: temperature, pressure, dosing formulation ...;- the implementation and validation of a Finite Element Analysis model to predict the thermomechanical stresses resulting from the processes and optimize the mechanical properties of the module.Experimental tests validated the mechanical model and provided other properties like the photoelectric performance of these curved panels. Further research includes the optimization of the processes parameters for large structures and the optimization of the reliability and performance of the module. |
