Al-ZnO / CuO_CFRP ORGANIC STRUCTURAL AUXILIARY ENERGY STORAGE SYSTEM FOR ELECTRIC VEHICLE

Abstract

Electric vehicles (EVs) have tremendous potential in the context of curtailing greenhouse gas emissions within the transportation sector. The main drawbacks of the EVs are: battery pack increased weight, limited range and required additional electricity generation source to charge the batteries. The contribution of the coal plant to the production of electricity is 57% and emissions 1.4 kg / kWh, while gasoline 35% and 1.2 kg / kWh respectively. Nanocomposite technology in automotive industries makes the vehicle more energy efficient, by cutting the emission with reducing weight. The main objective of this study is to develop a structural energy storage system using aluminum-doped zinc oxide / copper oxide carbon fibre reinforced polymer (Al ZnO/CuO_CFRP) sandwiched 70gsm/20gsm paper dielectric structural organic super capacitor (OSC) for EV body panel. A conceptual laboratory model has been developed to find the suitability of structural Al-ZnO/CuO_CFRP OSC as EV body panel, which is considered as the energy generation and storage system. The OSC has considered as the roof panel of EV and it has tested at a solar temperature of 300C. The test results show that the energy conversion efficiency (ηec) of 19%, voltage (V_oc) 2800 mV, current density (J_sc) 522 mA/cm², capacitance (C) 20.15 µF/cm², energy density (E_d) 120 Wh/kg, and power density (P_d) 29 kW/kg. It would be able to reduce EV battery size by 15%, weight 7.5% and battery charging power 9%. Furthermore, the OPSC-EV roof panel would contribute to the reduction of greenhouse gas (GHG) emission 25% and help transport the population with a low level of carbonization.
