The Ministry of Industry and Information Technology released the 8th batch of recommended models for the promotion and application of new energy vehicles in 2018.

On August 2, 2018, the Ministry of Industry and Information Technology released the catalogue of recommended models for the promotion and application of new energy vehicles (8th batch in 2018), including a total of 385 models. Among them, there are 51 new energy passenger cars, 152 new energy buses and 182 new energy special vehicles.

According to the statistics of the battery China network, the 385 models in this batch of recommended catalogues involved 71 supporting battery companies, compared with the seventh batch of recommended catalogs. Among them, Ningde era ranked first in the battery supporting list with 90 models, accounting for 23% of the total models; followed by Beijing Guoneng supporting 28 models, accounting for 7%; the third is Guoxuan Hi-Tech, supporting 24 models The model has a percentage of 6%. The top 10 battery companies in the number of supporting models, the sum of the number of models supporting the model accounted for 62% of the total number of models in the recommended catalogue of this batch, and the concentration of supporting models of mainstream battery companies compared 68% and 69% of the catalogues of the sixth and seventh batches. There has been a decline.

Lithium iron phosphate exits the new energy passenger car supporting the new energy special vehicle

Among the 385 new energy models, 201 lithium iron phosphate batteries, 117 ternary batteries, 32 lithium manganese oxide batteries, 19 fuel cell packages, 6 lithium titanate batteries, and multi-component lithium battery 3 models, 2 lithium-rich manganese batteries, 1 lithium iron phosphate and super capacitors, and 4 types of lithium-ion batteries.

It is worth noting that in the recommended list of this batch, the lithium iron phosphate battery is not equipped with new energy passenger cars, but the proportion of new energy special vehicles has increased. According to the technical requirements of the new energy vehicle subsidy policy for 2018, the energy density of the battery system is not less than 115Wh/kg, and all types of batteries can reach the standard, because the lithium iron phosphate battery is more cost-effective and safe. Advantages, therefore, the battery technology route for new energy special vehicles has a tendency to shift to lithium iron phosphate batteries.

This batch of catalogues also has a bright spot. The lithium-rich manganese battery supporting models have been approved by the recommended catalogue, and two pure electric vans have been supplied, which are the Ludifangzhou  RQ5026XXYEVZ1 and the new one produced by Jiangsu Ludifangzhou New Energy Vehicle Co., Ltd. The new day brand XRF5032XXYBEV produced by Japan (Wuxi) Development Co., Ltd., the energy density of the battery system reached 140.03Wh/kg and 151.48Wh/kg respectively, and the supporting battery companies were all excellent power.

There is also a Yishengda QF6110HEVNG plug-in hybrid city bus produced by Liaoning Ganfeng Special Vehicle Co., Ltd., which is equipped with lithium iron phosphate battery and super capacitor. It is composed of Wanxiang A-Twenty-three System Co., Ltd. and Jiangsu Set. Shengxingtai New Energy Technology Co., Ltd. is jointly supported.

The overall performance of the battery is increased by an energy density of over 120Wh/kg, which accounts for 89%.

From the perspective of the energy density of the battery system, the energy density of the battery system of the pure electric vehicle is 89% at 120 Wh/kg and above. The energy density of the battery system is up to 165.45Wh/kg. It is the Junfeng brand DFA7000A1F4BEV pure electric car produced by Dongfeng Motor Group Co., Ltd. It is equipped with the ternary battery provided by Henan Lithium Power Co., Ltd.

The following is a detailed analysis of the energy density of each pure electric vehicle battery system:

In terms of pure electric passenger cars, the battery system density of the 47 pure electric passenger cars in this recommended catalogue is 98% of the energy density of 120Wh/kg and above. According to the technical requirements of pure electric passenger vehicles in the 2018 subsidy policy, the energy density of the power battery system is not less than 105Wh/kg, and the model of 105 (inclusive)-120Wh/kg is subsidized by 0.6 times, 120 (inclusive) - 140Wh. The model of /kg is subsidized by 1 time, the model of 140 (inclusive)-160Wh/kg is subsidized by 1.1 times, and the model of 160Wh/kg and above is subsidized by 1.2 times. 98% of pure electric passenger car models in this batch of recommended catalogues are eligible for a factor of 1 or more. Among them, 31 can receive 1.1 times subsidy, and 5 can receive 1.2 times subsidy.

In terms of pure electric vehicles, the energy density of the battery systems of the 178 models of pure electric vehicles in this batch of catalogues all exceed 115 wh/kg, which are in line with the technical requirements of the 2018 new energy vehicle subsidy policy.

In terms of fast-charged pure electric buses, according to the subsidy policy of 2018, the fast charge rate of fast-charged pure electric buses is higher than 3C, and the models with fast charge ratios between 3C-5C (inclusive) are subsidized by 0.8 times; The model between 5C-15C (inclusive) is subsidized by 1 time; the model above 15C is subsidized by 1.1 times. The four fast-charged pure electric bus models in this batch of recommended catalogues have a fast charge ratio of 3 models in the range of 3C-5C (inclusive) and 0.8 times subsidy; 2 models have a fast recharge rate of 5C- Between 15C (inclusive), you can get 1 time subsidy.
