402030 battery.Diversified technical routes for special vehicle power batteries

　　On June 12, 2019, the Ministry of Industry and Information Technology released the "Catalogue of Recommended Models for the Promotion and Application of New Energy Vehicles" (the 5th batch of 2019) on its official website, including a total of 2,446 models. Among them, there are 2,132 models that meet the product technical requirements in 2019, accounting for about 87%; there are 314 models that meet the product technical requirements in 2018, accounting for about 13%. In terms of product types, there are 582 models of new energy special vehicles. The Research Department of the Power Battery Application Branch further analyzes the new energy special vehicle products that have entered this recommended catalog:

　　In terms of power type, among the new energy special vehicle models selected this time, there are 581 pure electric models and 1 fuel cell special vehicle.

　　According to statistics from the Research Department of the Power Battery Application Branch, the 582 new energy special vehicles shortlisted for this batch of recommended catalogs come from 109 car companies. Among them, Zhengzhou Yutong Heavy Industry has the largest number of new energy special vehicle models shortlisted, reaching 33; the top five car companies are: Nanjing Jinlong (32 models), Yantai Haide Special Purpose Vehicle (27 models), Dongfeng Motor and Beiqi Foton each ( 24 models), Geely Sichuan commercial vehicles (23 models).

　　From the perspective of power battery technology routes, there are also many types of battery technology routes for new energy special vehicles in this batch of recommended catalogs. Overall, lithium iron phosphate batteries are the main ones, followed by ternary batteries, accounting for 55.5% and 38.0% respectively. . Other battery types include 17 lithium manganese oxide batteries, 10 multi-composite lithium batteries, 9 unspecified lithium-ion batteries, and 1 each of lithium-rich manganese battery and fuel cell. Among them, the fuel cell is provided by Shanghai Reshaping Energy.

　　Judging from the supporting battery companies, the 582 new energy special vehicle models selected in the recommended catalog are provided by 53 battery companies. Among them, the number of supporting models of CATL far exceeds that of other companies, reaching 132 models; other top-ranking battery companies and the number of supporting models are Guoxuan Hi-tech with 60 models, Lishen with 56 models, Beijing Guoneng with 35 models, BYD and Yiwei There are 28 models each for lithium and energy.

　　From the perspective of battery system energy density of pure electric special vehicles, in this batch of recommended catalogs, except for 10 models whose battery system energy density is unknown, only 4 models have battery system energy densities lower than 125Wh/kg. The other models all meet the 2019 fiscal subsidies. Require. Among them, the energy density of the battery system is as high as 179Wh/kg. Dongfeng Times provides support for two pure electric multi-purpose trucks of Dongfeng Nissan. The battery technology route is ternary battery.

　　In addition, the four models with battery system energy density lower than 125Wh/kg are two Hualin brand pure electric sweepers specially equipped by Beijing Guoneng, and Zoomlion brand pure electric sweepers supplied by BYD. Road Truck and Jiangsu Zhihang are supporting Shuchi Bus’s Shuchi pure electric van transport vehicle. Among them, only the Shuchi van transporter’s battery technical route is ternary battery, while the battery technical routes of the other three models are all lithium iron phosphate batteries.
