Energy recovery system for extended-range electric vehicle

Abstract

The present invention belongs to the technical field of energy recovery, and in particular provides an energy recovery system for an extended-range electric vehicle. The extended-range electric vehicle includes a turbine engine (100), a generator (200), a battery pack (300), a drive motor (400), wheels (500) and a control device (700); the energy recovery system includes a thermal element (600), the thermal element (600) is connected with the control device (700) and the turbine engine (100), and used for converting braking energy of the wheels (500) into thermal energy for heating intake airof the turbine engine (100). According to the invention, the braking energy of the extended-range electric vehicle is converted into heat energy by installing the thermal element, and is used for secondary heating of the gas entering a combustion chamber, thereby improving the temperature of intake air of the combustion chamber, so as to improve the power generation of the unit fuel, the enduranceof the extended-range electric vehicle is prolonged.

Description

technical field [0001] The invention belongs to the technical field of energy recovery, in particular, the invention relates to an energy recovery system for an extended-range electric vehicle. Background technique [0002] Car braking is to apply a reverse force to the car to slow down or stop the car. In the era of fuel vehicles, this reverse force for braking can only be provided by the mechanical braking system. Braking with gears, that is, using engine resistance to participate in braking, this operation is conducive to timely deceleration and parking, but the entire braking process will consume a lot of energy that cannot be recovered, resulting in energy waste. [0003] For electric vehicles or hybrid vehicles, the motor can be used as a driving motor or as a generator, so when braking, the motor can participate in braking by giving a reverse torque and realize energy recovery, that is, in During the braking process, the wheels drive the motor to rotate, and the mot...
