Before talking about BYD Tang DM, we can look at the hybrid technologies of foreign car companies: first, Japanese hybrid systems represented by Toyota, Honda and Nissan have both non-hybrid and hybrid power, and the core technology is "power split", the most striking of which is the "dual-motor power sub-genre" of Toyota Group; Second, the German hybrid system of "single-motor dual-clutch faction" represented by the German Volkswagen Group is mainly plug-in, giving consideration to power performance and energy saving and environmental protection; Third, the "extended range hybrid system" (series structure, pure electric drive) represented by American General Group has been proved by the market to have a bleak future. At present, GM, Ford and FCA all have various forms of hybrid systems, and their comprehensive performance is not as good as that of mainstream products in China and Japan.
Let's make a simple technical comparison between BYD Tang in China and Toyota in Japan.
From the configuration of plug-in hybrid system, the new generation Tang DM adopts the high-order configuration of "P0+P3+P4", while the new generation Toyota Prius plug-in hybrid adheres to the single configuration of patent application "PS". Judging from the actual effect of real car owners, BYD's "P0+P3+P4" configuration has finer division of labor, faster power, more diverse power combination modes, and very strong fuel-saving and four-wheel drive off-road functions. Toyota's "PS" configuration structure is compact, and its power performance and technical ductility are average.
In short, compared with Toyota, the new generation of Tang DM technology can be summarized as the following four highlights:
First, the brand-new BSG motor architecture can be directly driven by the engine to generate electricity. The front drive motor and the front axle are still connected and can be driven at any time. The engine load is less, the noise is less and the overall noise control is better.
Second, the brand-new rear axle drive motor brings stronger performance. The powerful rear axle drive motor has the maximum power of 180kw and the torque of 380 Nm.
Third, smarter electronic control management optimization is more economical and energy-saving. Using the economic interval of the engine to generate electricity can effectively balance the electricity and reduce the occurrence of power feeding in the case of urban congestion.
Fourthly, the ride comfort is improved, which is also attributed to the brand-new BSG engine. When it comes to hybrid power, BSG can directly pull the engine to the appropriate speed and then connect it, and it will not feel frustrated at all.
Judging from the current market reaction, the birth of BYD's third-generation DM dual-mode hybrid technology has created a successful example of "P0+P3+P4" configuration at the forefront of the world. The motor in each position can find the optimal output scheme, which can not only accelerate quickly, but also save energy and protect the environment, so that more users have the opportunity to experience the technical achievements of plug-in hybrid power system in terms of power, fuel saving, ride comfort, mute and off-road, and let consumers know what position China plug-in hybrid power technology benchmark can occupy in the global hybrid power industry.
