Recently, the Ministry of Industry and Information Technology released the 'Catalog of Recommended Models for the Promotion and Application of New Energy Vehicles (2nd Batch in 2021)The author noticed that in this batch of recommended catalogs, the biggest highlight is the Beijing brand BJ700USD8-BEV pure electric car with battery system provided by Guoxuan Hi-Tech. The energy density of the battery system exceeds 200Wh/kg, which is unprecedented in China. 200.22Wh/kg. Figure: Screenshot of the data from the Ministry of Industry and Information Technology. This is a qualitative leap that Guoxuan High-Tech has achieved in terms of battery system energy density, because in 2020, Guoxuan High-Tech's supporting battery system has the highest energy density of only 161.36Wh/kg. Among the 1-13 batches of new energy passenger vehicle announcements in 2020, the battery system with the highest energy density is SKI. Its supporting Jihu brand has a battery system energy density of 194.12Wh/kg; the next is Ningde era, the supporting BAIC WU5 , BAIC EX3, the battery system energy density is 190.1Wh/kg. The third is Gateway Power, its supporting Euler R1, the battery system energy density is 176Wh/kg, and the fourth is Funeng Technology, the supporting GAC AionLX, the battery system energy density is 170Wh/kg, which is the only one in 2020 4 companies that can provide energy density of battery systems above 170Wh/kg. It is worth noting that since September 2020, the energy density of the passenger car battery system for CATL has decreased significantly. This may be related to the occurrence of multiple fire accidents in GAC AionS equipped with CATL811 batteries at that time. Another point is that the current Guoxuan Hi-Tech battery system energy density of 200.22Wh/kg, equipped with Beijing brand BJ700USD8-BEV pure electric car, its cruising range is 470km. This shows that in terms of volumetric energy density, Guoxuan Hi-Tech's battery system needs to continue to be optimized!
