DESIGN OF LIGHTWEIGHT ELECTRIC VEHICLE AND APPLICATION FOR EFFICIENCY CHALLENGE MARATHON COMPETITION

Many vehicle manufacturers have started up the development and production of electric vehicles reducing in response to climate change, increasing air pollution and exhaust emission problems. In addition, the most important of the difficult problems associated with electric vehicles is the high cost caused by the use of a large number of batteries and the use of a limited number of batteries negatively affects the driving distance of the car. The limitations caused by the battery problems are not only to increase the cost but also increase vehicle load because it takes up too much space and limits the usage area of the vehicle. In order to address these problems, electric vehicle manufacturers have tried to find a way to reduce the weight of the vehicle body. Therefore, to reduce weight, it would be more accurate to use light metal alloys that could get better results than using polymer composites in this study 6063 series aluminum alloy box and tube profiles were used as chassis materials, and birdcage chassis production was carried out by combining these profiles with MIG welding. After production is completed, the steering system, brake system, suspension system and other moving parts are installed on the chassis. As a result, the final weight of the vehicle was 210 kg and the negativity that may occur was prevented.
