Toyota's technology is really powerful. 1990 after the third oil crisis, Toyota set up a new energy project. 1997 launched the world's first hybrid model-Prius. It has been 24 years now, and the technology is very mature. Therefore, after the 20 14 pure electric vehicle started to stir up, Toyota was in no hurry at all, let alone Japanese. The cost per kilowatt-hour is 7.8 yen, which is RMB 4.6 yuan, while China is 1.5, and Japan is about three times that of China. Because of the high cost, Toyota, Honda and Nissan are all playing hybrid power, but Mazda does not play directly. This is the overall development direction of Japan, so Toyota does not pay much attention to the development of pure electricity.
It was not until 20 16 that the turnaround was ushered in. This year, first of all, the whole world tightened the exhaust emission and implemented Euro 6C. Subsequently, Volkswagen was fined more than $20 billion in the United States for emissions fraud. Boy, this time seriously, in order to save energy and reduce emissions, the simplest three-cylinder machine appeared first. Of course, car companies also know that three cylinders are not a long-term solution. So we still need to develop pure electricity. Subsequently, Mercedes-Benz, BMW and Audi, as luxury brands, took the lead in announcing the start of electrification strategy, and then GM, Ford and Nissan also joined in.
Toyota's electrification strategy was announced in April 20 18, but Toyota's electrification is broad, including pure electricity, plug-in hybrid and hydrogen fuel, in which hydrogen fuel and hybrid are the core, and Toyota is not optimistic about pure electricity. Akio Toyoda didn't bombard pure electricity once. According to him, the more electric cars there are, the more serious the carbon dioxide is, which is a conspiracy of a certain family. Toyota has never wanted to develop pure electricity, and it will not play pure electricity unless the situation forces it. Therefore, pure electric vehicles, namely CHR-EV and Yize E, will not be launched until 2020. However, this car obviously does not meet the domestic situation. Both cars have a cruising range of 400 kilometers, which is not too good or even a bit backward.
Let's look at other brands. At this price, the Model3 has a cruising range of 468km, the P7480km, the Extreme Focus Alfa T 480 and BYD Korea 605km, which can basically be said to be the overlord of the 200,000 class. So after the comparison, you will find that Toyota's competitiveness is too low, not only expensive, but also has no advantage in battery life, which runs counter to the purpose of high cost performance of Toyota family cars. Of course, the sales volume is also ugly, with more than 100 vehicles per month.
Besides, Toyota's best hydrogen energy vehicle is said to be the most perfect energy source, but due to safety problems, Mercedes-Benz and General Motors terminated the development of hydrogen energy last year, and Nissan also terminated the development in June+10 this year, focusing on pure electricity. I can't take this Toyota with me at first sight. I play a P alone, and I can only choose the way of cooperation when my products can't keep up with the big trend and can't change it.
Moreover, there is the mountain of emission integral, which is the policy of double integral, average fuel integral and new energy integral in China. If this is up to standard, cars can be produced normally, otherwise production will be stopped. Therefore, Toyota has to pay close attention to the layout of electric vehicles in order to score points. Isn't BYD the best choice to add a technology to this point? Moreover, it's not just Toyota that secretly loves BYD. Wang Chuanfu revealed before April 7 that almost every brand you can think of is talking about cooperation intention with BYD and purchasing blade batteries. Among them, Hongqi EQ-m5 is the first model equipped with blade battery except BYD Korea.
First of all, BYD started with batteries. The car should be regarded as a sideline after it became rich, that is, it started in 2003, and the battery started as early as 1995, so as a technical development reserve, it was originally a pioneer. Around 20 16, almost the whole new energy industry is pursuing ternary lithium batteries, and BYD is no exception. The advantages of this kind of battery are high density, significantly improved battery life, and obvious disadvantages, that is, safety. I believe that during that time, netizens also watched the news of spontaneous combustion of various brands of electric vehicles. Therefore, in 20 17, BYD set up an independent department with the development direction of safer lithium iron phosphate batteries. After three years of research and development, the blade battery was born in 2020, and this independent department was also split up and became Shenzhen Fudi Battery.
So what are the advantages of blade batteries?
First, it must be safe. The ternary lithium battery used by most car companies will have a chemical reaction at about 200 degrees, causing thermal runaway and spontaneous combustion and explosion, while the blade battery can reach 500 degrees. In addition, there is a collision problem. Last year, BYD's Chongqing factory conducted an experiment. Both the blade battery and the ternary lithium battery car did acupuncture experiments, and the ternary lithium battery burned directly after acupuncture. Therefore, for safety reasons, the blade battery in lithium ferrous phosphate must be given priority.
The other most important thing is battery life. Blade batteries are called blades because they are arranged together to form an array, and each single battery is inserted into the battery pack like a blade. This method reduces redundant modules, realizes higher space utilization, makes up for the disadvantage that the density is not as good as ternary lithium, and meets the dual requirements of safety and long battery life. So you see that BYD Han is almost the overlord of the same level, which is both safe and has a battery life of 600 kilometers.
In addition to the top battery technology, BYD's motor and electronic control development is also in a leading position. Because it developed too early, technical reserves have always been there, just like Toyota's hydrogen energy, but the current trend is pure electricity, and there may not be a day when hydrogen energy will turn over in the future. But now Toyota really needs the most advanced pure electric technology, so the cooperation with BYD will be relieved.
One of the concerns of many netizens is to pay attention to confidentiality and not to be exploited by Toyota. Actually, don't worry about this. A group's core technology plus patent protection is not so easy to break. Didn't Toyota study Tang as early as 20 18? It didn't work out in the end. So, will you choose a pure electric car or a hydrogen energy car? Welcome to leave a message for discussion.
