Many domestic cars use plug-in hybrids, while Japanese cars often use non-plug-in hybrids, mostly oil-electric hybrids. Which technology is better, plug-in hybrids or non-plug-in hybrids? What are the disadvantages of plug-in hybrids? Will the driving force of plug-in hybrids be worse? Why are all domestic cars plug-in hybrids? Let's take a look at the following content for details! Which technology is better, plug-in hybrid or non-plug-in hybridPlug-in hybrid and non-plug-in hybrid, in terms of technology, non-plug-in hybrid is obviously more advanced, more practical, less affected by the external environment, and less pollution in the later stage. Plug-in hybrid is simpler and has low technical content. Toyota and Honda's non-plug-in hybrids focus on fuel economy, and their performance is not outstanding. In addition to fuel economy, plug-in hybrids can also have good performance. However, their durability and mileage are not ideal. Each has its own advantages and disadvantages. What are the disadvantages of plug-in hybrids?The electric drive system that is good at low speed and the fuel drive system that is good at high speed are installed on a car, just like a donkey that is good at carrying weight and a horse that is good at running are harnessed to a cart. At low speed, the donkey pulls the cart, its heavy fodder, and the horse lying on the cart to rest. At high speed, the horse pulls the cart, the donkey lying on the cart to rest, and a pile of rough fodder for the donkey. It is not as good as electric cars at low speeds and not as good as fuel cars at high speeds. The dual system results in an increase in weight and volume. At low speeds, the increased weight increases rolling resistance, which has a greater impact on energy consumption. At high speeds, the increased volume increases wind resistance, which also results in increased energy consumption. Why do domestic cars use plug-in hybrids?The technical content of electric hybrid is relatively high, because plug-in hybrid can run on pure electric power, while oil-electric hybrid cannot. The battery capacity of plug-in hybrid is relatively large, and it can run on pure electric power for at least 50 kilometers. The battery has two functions: one is to accept external charging, and the other is to recover electric energy during braking for next use, saving fuel. The battery capacity of oil-electric hybrid is relatively small, the battery cannot accept external charging, and there is no charging port. The function of the battery is to recover energy during braking. During driving, the battery assists in driving the vehicle through the motor, reducing the power output of the engine, thereby reducing fuel consumption. |
