Embodiment Construction
[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, and only illustrate the basic principle and structure of the present invention in a schematic manner, so they only show the configurations related to the novelty of the present invention. The evolution around the basic principles, such as alternator and dc generator, ac motor and dc motor, although not expressed one by one, is also involved in the present invention.
[0019] Such as figure 1 As shown, the generator set includes two engines and generators to generate electricity, which is directly input to the drive motor through the variable speed control circuit. When the engine is generating electricity, the fuel efficiency ratio of the engine can be better utilized. In the state of electric driving, especially in the state of acceleration from the start, the efficiency of electric driving is higher and it is easier...

The invention discloses a direct electric drive hybrid vehicle with electric power provided by in-vehicle power generation. The invention is applied to the field of passenger vehicles and new energy vehicles in an automobile industry. An engine in the vehicle generates electricity instead of directly driving a gearbox, and the motor is directly driven through variable speed control. The efficiency of engine power generation is higher than that of direct drive gearbox, and meanwhile the efficiency of electric drive is higher than that of mechanical drive. The generated electric energy does not need to be stored and then discharged. The invention further provides a kinetic energy recovery and storage system. Brake kinetic energy is collected and stored in the energy storage battery after being stabilized and rectified, the energy storage battery is switched to a battery working mode after being fully charged, the energy storage battery does not need to be specially and externally charged, 100% deep charging is met in the using process, and attenuation is avoided in a service life. The problems of battery weight, charging and discharging of a pure electric vehicle, oil consumption of a fuel vehicle and cost and efficiency of a hybrid vehicle are solved. The problem that various new energy vehicles are high in cost and price is solved too.
Description
technical field [0001] This patented technology is applied to the field of passenger cars and new energy vehicles in the automotive industry. Background technique [0002] Fuel passenger cars have a history of more than 100 years, and the body structure and transmission are very mature. However, due to contradictory coordination factors such as output power, speed and torque peak, the engine power must be too large to meet the normal driving requirements. From low power at the start to high speed High power, the difference is too big, and the weight of the engine has also increased, which is the first shortcoming. In urban working conditions, the maximum speed is usually only 80 km / h, while the speed at high speed reaches 130 km / h, and the power output is more than doubled. To meet these requirements, the power of the engine is often made too high. When driving in urban conditions, the power output only needs to be less than half of the rated power of the engine. For a lar...
