Key Technologies for New Energy Vehicles Aimed at Improving Energy Efficiency

With the rapid development of new energy cars, the problem that the battery life is generally short due to poor energy consumption control has come to light. Nowadays, researchers have conducted studies and achieved results in areas such as electronic control, motors, batteries, and tires. This essay discusses the energy management strategies for new energy vehicles in terms of body design, power system, and battery optimization. The energy consumption can be reduced by using bionic design to reduce the wind resistance coefficient, using lightweight materials, optimizing the transmission and motor to enhance energy efficiency, and improving the energy recovery and battery management systems. Thus, the endurance mileage can be improved. In addition, fuel cell technology offers new solutions for energy consumption management in the future. Through these strategies, the new energy vehicles will have better performance of energy consumption, which meets the sustainable development goals. This paper will provide reference significance for automobile designers and engineers in terms of reducing energy consumption.
