Climate change and global warming is one of the major challenges faced by the world today. A significant number of Indian cities rank among the most polluted globally, with vehicular emissions being a primary contributor. To address this issue, Government of India is actively advocating for the adoption of zero-emission vehicles, such as electric vehicles, through policies and initiatives like FAME II, PMP, and the National Mission for Transformative Mobility and Storage. The acceptance of electric vehicles is growing in the Indian market seeing more than 200 % increased sales with large shares of 2-wheelers, 3-wheelers & compact cars getting electrified. One of the major inhibitors to EV sales being the high overall electric vehicle cost compared to conventional vehicles with HV battery is the most costly system on the present day electric vehicles . An electric vehicle having high energy efficiency can meet it's driving range requirements with a relatively smaller battery size thereby leading to lower costs. Electric vehicle energy efficiency improvement can be achieved not only by reducing the losses at main powertrain components like electric motor, HV battery, transmission, vehicle rolling resistance etc. or improved aerodynamics but also by an energy optimised thermal management system. The presented study focuses on reducing the energy demand of the integrated thermal management system of an electric vehicle. As a case study one of the most selling electric vehicles of the Indian market was selected and assessed for the energy consumption. As a next step optimal sizing of the thermal management components like cooler, heaters, coolant pumps etc. was done including the introduction of advanced technologies like optimised and innovative control strategies application such as predictive thermal management control (e.g., intelligent preconditioning, cabin air recirculation control and smart ventilation) for cooling, or heat pump integration along with heat harvesting strategies for heating. In addition, integrative measures were also assessed to reduce the energy required for cabin air conditioning. The solutions also included local heating systems such as radiant panels or heated seat belts, as well as thermoelectric elements for cooling or heating via the seat surfaces. With the applied improvement solutions the vehicle energy efficiency and driving range increased. All the simulations were performed on well validated GT SUITE simulation models from FEV. India being a cost sensitive market an assessment of added cost for implementation of these solutions was also done to check the impact to cost ratio of each optimization approach.
