Mention of hybrid technology, it is absolutely impossible to bypass the Japanese hybrid, in the field of hybrid vehicles, Japanese cars in the world can be described as a thriving existence, and the japanese car hybrid is monopolized by the two fields and one production, in daily life, whenever the hybrid is mentioned, we will always say Toyota THS, Honda iMMD system, Nissan seems to be forgotten, in fact, Nissan also has its own hybrid system - e-POWER, Nissan's hybrid is not known to everyone, not that it is not OK, but it came too late. Nissan hybrid system e-POWER was launched in Japan in 2016, so far, its sales in Japan has exceeded 500,000, after the product has been verified in Japan, Nissan began to popularize the hybrid system around the world.
Hybrid systems for Toyota and Honda
Toyota's hybrid system, it adopts the hybrid mode, in a specific working condition, the engine and motor can directly drive the car, and the control of the power conversion device is E-CVT, E-CVT is actually not a transmission, it is a power conversion device, under the matching of the device, the engine and motor can always work in the most efficient area, so as to achieve the lowest energy consumption, in comparison, the energy distribution device of the Toyota hybrid system is more advanced, It makes it easy to match the energy between the engine and the electric motor.
Honda's IMMD hybrid system, it is mainly composed of Atkinson cycle engine, clutch, dual motor, three-shaft, etc., the engine is connected to the engine output shaft through the clutch, connected to the generator by the gear before the clutch; the motor is directly connected to the motor output shaft, the engine and the motor can transmit power directly to the wheel tires, under the matching of the system, Honda's iMMD system can achieve "pure electric mode", "series hybrid mode", "parallel hybrid mode".
Nissan's hybrid system
Nissan's hybrid system is different from Honda and Toyota, it uses a full-time electric drive structure, no matter at what time, the car is directly driven by the motor, the engine will not directly transmit power to the drive wheel, it is this layer of meaning, Nissan's hybrid system is a bit of a range extender electric vehicle flavor.
Nissan e-Power vehicle in the driving process, all working conditions are 100% driven by the motor, the engine will only start in the case of insufficient power, and the efficiency of the engine is very high, which also makes Nissan's engine has a very low fuel consumption, so Nissan's hybrid system directly omits transmission components such as transmissions, and nissan has certain advantages in terms of cost and lightweight design. Since the Nissan hybrid system e-POWER, all working conditions are directly driven by the motor, so the driving feeling of the Nissan hybrid is almost the same as that of pure electric vehicles, the power output is smooth, the vehicle responsiveness is excellent, and the throttle response is sensitive.
I don't know if you have test driven Nissan Xuanyi e-POWER, although it matches the 1.2L three-cylinder engine, the maximum power is only 72Ps, but this does not affect the driving of Xuanyi this car, people matched the 300Nm torque motor, the motor is enough to meet the daily use of the owner. Seeing Xuanyi's fuel consumption of 1.2L, you will be surprised, how can its fuel consumption be as low as 3.9L/100km? This is closely related to the ultra-high thermal efficiency of the engine, the three-cylinder version of the 1.2L engine, its thermal efficiency is as high as 43%, and only works in the most fuel-efficient areas, there is such a low fuel consumption, it is not an exaggeration!
Regarding the hybrid system of Japanese cars, I don't know what you have to say? Welcome to leave a comment!
