In-vehicle double-engine power generation direct electric drive hybrid power vehicle

Abstract

The invention is applied to the field of passenger vehicles and new energy vehicles in the automobile industry. Two fuel engines with half power compared with a conventional fuel vehicle engine are arranged in the vehicle to generate power, and a motor is directly driven through variable speed control. The generated electric energy does not need to be stored and then discharged. A low speed driving state in urban comprehensive working condition is satisfied, only one engine works, and the optimal efficiency of the low-power engine under low-speed driving is achieved. In a high-speed driving mode or a motion mode, the two engines work at the same time, and the demand for publishing output multiplication is met. The invention further provides a kinetic energy recovery and storage system. The 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 the 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 power 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...
