On September 28, BYD held an online European launch conference for new energy passenger cars, launching three models for the European market, including Han EV, Tang EV and Yuan PLUS. The content of the introduction of the models in this press conference is very familiar to us. The most attractive thing is the price of these three cars. The pre-sale price of Yuan PLUS in Germany is 38,000 euros, and the pre-sale price of Han and Tang Germany is 72,000 euros. Many people have begun to compare prices with German fuel cars, such as BMW 5 Series , Mercedes-Benz E, etc., but after all, they belong to two camps and are incomparable in terms of car use habits, but the Tesla , which is also sold in Germany, was injured.
In China, BYD and Tesla are top competitors against Maimang. I don’t know how many verbal battles have they fought for which car is better online. Tesla and BYD are also among the best in sales. Tesla is still higher than BYD in terms of price. However, look at the price of Tesla Model Y in Germany, 51,000 euros to 67,000 euros. Which one is higher and which one is lower is clear in the foreign market.
Tesla's leading position
If Tesla's "black technology" is said to be in hardware, Tesla, as a technology company, has a very clear positioning. In the past few years, the battery on the car mainly purchased ternary lithium batteries from Panasonic . Recently, it was mainly used for domestic production with battery companies such as CATL. The motors on the car were purchased from Futian, Taiwan. Tesla's high-end models use AC asynchronous motor , while the mid- and low-end models still use permanent magnet synchronous motor . Although BYD started late in motor technology, the upper limit of permanent magnet synchronous motor is there. The gap between the two is not big. Tesla's really powerful is electronic control technology and assisted driving technology.
Tesla's fully independently developed BMS electronic control technology can be said to be very outstanding. It is a top-notch existence in the entire electric vehicle industry. Powerful electronic control technology can make the battery work more stable. Simply put, BMS electronic control technology can monitor every battery in the entire vehicle, adjust the output of each battery according to different vehicle conditions, effectively saving electricity. Another advantage of this monitoring is that it makes the power of the vehicle very smooth linearly, such as acceleration and head-up, slowing down and nodding, etc., driving experience is much better than BYD.
For example: Tang EV Exclusive model has a total power of 180kW and a total torque of 350N·m. It is equipped with a battery of 108.8kW·h, with a range of about 730 kilometers. The Model Y rear-wheel drive version (lithium iron phosphate) has a total power of 194kW, a total torque of 340N·m. The battery capacity is 60kW·h, and a range of about 600 kilometers. It is not difficult to find through the comparison of these two models that the difference in power is not big, but the difference in range and battery capacity is very large. Part of this gap is the result of electronic control technology control, but it is not that BYD's electronic control technology is useless. Tang EV, as a 7-seater SUV, weighs 2.3 tons, while Model Y has only 5 seats, and the weight of the car is 1.9 tons.
followed by Tesla's assisted driving technology. The Autopilot intelligent assisted driving system independently developed by Tesla is far ahead of the industry, present or short-term future. The core of assisted driving lies in the close cooperation of information recognition and collection, data computing and analysis, and AI intelligence. The disciplines involved are even more complex. BYD's assisted driving starts later and has a significant gap, but Tesla's assisted driving needs to be purchased extra.
BYD's "Technology and Fierce"
It seems that Tesla does have its own uniqueness, but not many.
As the only world's first master of the core technologies of the entire industry chain of new energy vehicles such as batteries, motors, electronic controls and automotive-grade semiconductors, BYD's technology accumulation cannot be ignored. Many people do not know what it means to master the entire set of technologies. Take BYD's Tang DM-i for example. At that time, many car owners reported that Tang, as an SUV, had a pure electric range of only 112KM, which was not enough to see the end. So when BYD's Tang DM-p was released, it directly met the needs of consumers and launched the BYD's Tang DM-i 252KM version. The R&D design and accessories were all in their own hands. Change whatever they wanted, without additional considerations on the unstable body structure and the inability to install the battery.
As for BYD's blade battery , I don't need to repeat it. I will say it's annoying if you are tired of it.
knows that the battery life of electric vehicles is very important, but few people mention charging speed. In fact, I personally feel that charging speed is more important than battery life. Just like the previous mobile phones promoted battery capacity, after the popularization of fast charging technology, who else cares about how large the battery capacity is? It is enough to charge for five minutes after the battery is out of power, so the charging speed is also applicable to electric vehicles, but why aren't it mentioned? Because I can't handle it.
Now the upper limit of the voltage of the general charging pile is around 500V, which means that the battery pack voltage of an electric vehicle must be less than 500V before it can be rushed into the power, and there is a limit on the current limit. Therefore, if you want to make the charging speed faster, you have to consider how to increase the voltage limit of the battery pack. The high voltage of the battery pack is in conflict with the upper limit of the charging pile. In order to solve this problem, many car companies have begun to build super charging piles in various cities, and those who choose to replace batteries are avoiding the upper limit of the 500V voltage of the general charging piles.
, and BYD chose to develop its own boost charging technology, which is the famous "drive multiplexed boost charging technology". Boost charging can increase the voltage of a general charging pile through the boost circuit and then transmit power to the battery pack. Currently, the pioneer of boost charging technology is Porsche Taycan. The first electric car that uses charge pump to increase the voltage to 800V, followed by BYD's drive multiplexed boost charging technology.
BYD's boost technology is very complex. It forms three parallel boost circuits through the motor's coil and IGBT module . By adjusting the duty cycle and frequency of the three-phase different IGBT switches, the boost operation of the charging pile voltage is achieved. To put it simply, it uses the simple principle of the junior high school physical transformer. The voltage energy of alternating current is nothing more than the difference in coils.
However, this kind of innovation also requires consideration of the huge heat generated during boosting, and battery and electronic control technology must also be taken into account. At that time, the battery pack of BYD e5 reached 633.6V. If nothing unexpected happens, at least in the E platform 2.0 era, BYD began to deploy boost charging technology. The technology did not come out of thin air. Every black technology of BYD is explored step by step.
So, comparing BYD's technical accumulation and advantages, do you think it is reasonable or not to sell it at this price in Europe?
