The Chinese automotive group Chery (in Italy with the Omoda and Jaecoo brands) just made big announcements during its Global Innovation Conferencein the city of Wuhuin Anhui province. There are juicy innovations at stake, especially in the field of batteries, with the creation of the new internal brand Kunpeng.
Chery punta a batteries with solid state technologiesby energy density fino a 400 Wh/kgof which we will be able to see something in the prototype state already by the end of 2024, and then even reach 600 Wh/kg nel 2025. In the meantime, however, we will move on from more traditional batteries with liquid electrolyte, but with very high performance.
All batteries will have charging capacity of 6Cor a sixth of an hour to be fully recharged. Since maintaining maximum charging power is virtually impossible, it would be more accurate to describe the 6C as being able to support a maximum power of six times the capacity, such as 600 kW for a 100 kWh battery.
The batteries with LFP chemistry and prismatic format have a density of 120-160 Wh/kg and support electric vehicles with an autonomy of 200-600 km, while the ternary battery NCM prismatiche they have an energy density of 140-200 Wh/kg and find application in a range of 600-800 km.
Then there are the cells large format cylindricalperhaps similar to Tesla’s 4680, for electric vehicles with autonomy between 700 and 1,200 km. The very high power charging capabilities can also be used for plug-in hybrid cars and EREV vehicles. Furthermore, Kunpeng batteries can withstand 3,000 charging cycles, a good 20% more than the market standard.
All this with unspecified production and use times, but they are still considered immediate batteries, which we will therefore presumably see in Chery’s electric cars as early as 2025.
