Design and research of energy recovery devices for new energy vehicles

Abstract China is a large automobile consumer. With the continuous progress of science and technology, a variety of new energy vehicles have emerged, and the endurance problem of new energy vehicles has become more and more prominent. In this paper, a new energy vehicle energy recovery device is designed and studied, which makes full use of the inertia of the power battery when the car is running, recovers its energy, converts the kinetic energy of the power battery into electric energy, and transmits the energy to the power battery. In the process of energy recovery, an energy storage device is designed to fully improve the efficiency of energy recovery. It can increase the endurance capacity of new energy vehicles to 25%. The design can be widely used, such as household new energy cars, SUVs, large and medium-sized buses, etc. The design and promotion will certainly pave the way for the popularization and development of electric vehicles.
