BYD’s second-generation blade battery officially debuted in August 2024, and its biggest highlight is the breakthrough in battery life, which is expected to reach a range of more than 1,000 kilometers. Here are the details about the battery:
Technical features:
Energy density : The energy density of the second-generation blade battery is expected to reach 190Wh/kg, an increase of more than 35% compared to the first-generation blade battery (140Wh/kg). This significantly improves battery life 12.
safety : A new type of composite fluid collector and a new type of air-liquid mixed temperature equalizing heat dissipation system are adopted to improve the safety of the battery. These improvements allow the battery to remain stable under extreme conditions 12.
Volume group efficiency : through the unique concave pole design, the volume group efficiency of the battery is improved, and the driving range and performance of the electric vehicle is further improved.
Performance improvement:
Low temperature discharge capability : The second generation blade battery uses a new electrolyte formula to reduce the internal resistance of the battery and improve the low temperature discharge capability. The battery can also maintain 80% discharge capacity at -30 ° C, 10% more than the first generation .
Safety : The first generation of blade batteries has passed the needle, extrusion, high temperature and other stringent tests, safety is very high. The second generation of blade batteries continues to maintain advantages in these aspects, making people more secure .
Practical applications and industry impact:
Practical application : The second generation blade battery not only has high energy density, but also has guaranteed safety. The Mi SU7 is a good example, its standard version is equipped with BYD lithium iron phosphate blade battery and has a range of 700 km .
Industry impact : The emergence of blade batteries has attracted the attention of global car companies, including FAW, Changan, Toyota, Tesla and many other car companies have assembled or plan to assemble blade batteries. Byd also plans to introduce the fifth-generation DMI hybrid technology, feed fuel consumption down to 2.9 liters / 100km, full range of up to 2,000 km .
Future outlook:
With the continuous progress of electric vehicle technology, the penetration rate of electric vehicles may increase significantly in the future. If electric vehicles can achieve “five minutes of charging, 1,000 kilometers of driving”, this will greatly promote the popularity of electric vehicles. However, we also need to pay attention to the environmental problems caused by battery recycling and large-scale use of lithium batteries .
