Some time ago, Bingge tested a wheeled car. Unlike the powerful F1 racing car, this car is not even as fast as a bicycle, it is the Xiaomi balance bike No. 9. Although the performance is not strong, Bingge still used this electric car to simply run the "track" (built from an ice cone). Brother Bing challenged this "track" twice. The fastest lap speed of the first time is about 34 and a half seconds; the second time is to try it at full charge, with a lap speed of about 33 seconds.
Obviously, the battery power has a great impact on the performance of electric vehicles. In this case, for those new car-making forces that develop new energy vehicles, only by choosing a reliable battery cell supplier can we create excellent products. So, which suppliers do the following more well-known new energy vehicle brands come from?
Tesla
The early Model S and the Model X launched in the previous two years both use Panasonic 's 18650 ternary lithium battery cells. However, the Model 3 released last year uses 21700 cylindrical battery cells, jointly developed by Tesla and Panasonic. Theoretically, the larger the battery cell, the higher the energy density, but the curing process of lithium ions is also difficult. Although the cost and weight of a single 21700 cell has been increased, the weight and cost of the entire battery pack system PACK has been reduced.
Tesla Model X's motor comes from Futian, Taiwan and belongs to the asynchronous AC motor . Because Model X has strong power, using the permanent magnet synchronous motor will have a strong magnetic field, and a lot of iron filings will be absorbed at the bottom of the vehicle. However, mainstream electric vehicles are all moving towards permanent magnet motors, so Model 3 is changed to permanent magnet synchronous motors.
NIO
Near this year's Guangzhou Auto Show Pavilion, there are many registered NIO ES8 parked, indicating that its production capacity has gradually come on track. As a new energy vehicle company among its own brands, the three-electric technology of NIO ES8 basically comes from mainland China. In the battery cell part, ES8 uses the VDA square battery cell from the Ningde era.
Industrially speaking, squares are more difficult to process than rounds, but the space utilization rate of square objects is very high, so the energy density of the entire battery system of ES8 reaches 135wh/kg. The motor and electronic control parts of ES8 are both independently developed and use asynchronous AC motors, so the acceleration performance of ES8 is very strong.
WM
WM Motor uses VDA standard battery cells and modules, so its battery pack can be compatible with products from mainstream battery suppliers such as CATL, Tianjin Lishen, and Suzhou Yuliang. However, these battery suppliers do not use batteries of the same specifications. CATL mainly uses square battery cells, while brands such as Tianjin Lishen and Suzhou Yuliang all claim to be deploying 21,700 batteries, so WM Motor has more power batteries.
Since WM Motor's founder Shen Hui was once the president of BorgWarner in China, and the products under WM Motor do not require much power at present, the EX5 model uses a permanent magnet synchronous motor from BorgWarner, which is more efficient; and the electronic control part is also from BorgWarner.
Xiaopeng
In the field of new energy vehicles, the "Matthew effect" is becoming more and more obvious. Therefore, at this year's Guangzhou Auto Show, the new energy brands participating in the exhibition began to be streamlined, or they began to reshuffle! On the other hand, the new car-making forces that can participate in the auto show this year are definitely not small roles. As one of the three new car-making giants (NIO, Xiaopeng, and WM Motor), Xiaopeng Motors brought us Xiaopeng G3 this year.
Although Xiaopeng G3 will be launched at the end of this year, it is estimated that its R&D will be two or three years ago. Therefore, it uses 18650 battery cells from Bick, but as the production capacity of Lishen 21700 battery cells gradually increases, it will switch to a new power battery pack. The motor of Xiaopeng G3 comes from Jingjin Electric, which is the largest motor supplier among domestic non-vehicle companies. Since Jingjin Electric has relatively advanced technology, the power performance of Xiaopeng G3 is good.
Although China's electric vehicle brands (new car manufacturing forces) are still in the initial development state, if you look at the current global automobile companies, China's new car manufacturing forces are still at the forefront. In other words, our brand influence may not be comparable to that of many century-old automobile companies and international brands, but then again, consumers' loyalty to brands will gradually decline in the future, and what consumers most want is better product strength and better product experience. Brother Bing believes that in the near future, many Chinese auto companies will gradually step on the international stage with new energy vehicles, compete with international brands on the same stage, and achieve overtaking on the curve.
