Technical battle between America and China This is the most obvious example between Tesla and Byd in an electric car battery. American firm TeslaElon Musk, China face BideA few days ago, who announced a remarkable progress with his new battery capable of Ultra -Creted Recharge Processes (400 km autonomy of 400 km autonomy in five minutes of recharge), which has been raised equally.
Bide Use Iron lithium battery phosphateWhile Tesla uses a chemistry with a high nickel material (NMC811), provides more energy density (ideal for high performance cars). Special press has participated for testing and analysis of technologies to be used. One of the most striking findings is by BYD battery, baptism Blade cellAllows Recharge process faster three times That Tesla’s people but with Half of summer compared to your opponentThe conclusion is that in principle Fire risk This is low in the recharge process. The blade battery is supported by an official guarantee of 8 years or 200,000 km,
Expert of Frawnhofer InstituteThe DW report, after a complete analysis, is not a clear winner in front of the battery of Beddi’s battery Tesla and each design “responds to different preferences: Tesla is committed to high performance, while Beddi focuses on durability and low costs. The choice between the two technologies depends on the interests or performance on the interest.
A team of researchers at the Rwth University Aquisk (Germany) led by Jonas Gongs completely eliminated the BYD and Tesla battery to analyze the components. The study last month was published in the magazine ‘SAIL Report PhysicsAccording to the main conclusion of that study, Tesla prioritizes high energy density, which reaches 643.3 watt per liter, is ideal for high -vehicles. For its share, the byd focuses on the amount and the efficiency of the inexpensive material, which receives 355.3 watt per liter, allowing vehicles to offer at more affordable prices.
Criticism of field
A good part of analysts in the automobile sector consider that byd has achieved its first objective of attracting public opinion with an ultra -gord battery advertisement. But the truth is that there is still a lot of time for this advance to be popular among consumers due to the cost of the final product and the decrease of the new load speed. Mercedes-Benz has accused of launching Byd False advertisementAndrew Cornelia, CEO of Mercedes-Benz High-Power Charging, announced that most drivers do not actually require such quick recharge and in fact the autonomy and efficiency of the vehicle is a very important point. The idea is that to recharge 400 km of autonomy in just five minutes, a battery will require a charger capable of providing minimum 115 kWh capacity and 960 kW power, which is currently almost experimental.
technical analysis
The study of the gonch concludes that “the bead shows half of the blade cell Energy loss from volume Cell Tesla out of 4680. Cell Tesla uses 4680 laser welding, and byd blade uses laser and ultrasonic welding as cell electrode contact technologies. It is confirmed that iron and lithium phosphate (LFP; byd blade cell) and NMC811 (Tesla 4680) are electrode materials, resulting in 160 wh/kg and 355.26 wh/ly 241.01 who and 643.3 with, resulting in energy density. Both cells use graphite anode without silicon dioxide. Polycrillic acid (PAA) and polyethylene oxide (PEO) are found as binders on the edge of the Tesla 4680.
Share contribution
Byd actions He recorded his biggest growth in Hong Kong Bag after the announcement of his new battery in more than nine months, publishing the initial record for the third quarter by China’s largest electric car manufacturer. In a statement released to the bag on Tuesday night, according to the automobile manufacturer, the third quarter net earnings will reach 11,500 million yuan ($ 1.6 billion) as compared to the previous year’s 5.7 billion yuan. The profits in the nine months ended September 30 may be between 20,500 and 22,500 million yuan, all over the net profit of 2022, which were 16.6 billion yuan.
Industrial key
One of the reasons supporting byd’s success is that it also produces batteries that feed their electric and hybrid cars, as well as some semiconductor chips that create them. It is old Manufacturing capacity Byd allows more control on the supply chain, which means better cost control.
