Electric passenger car batteries that use lithium iron phosphate or ternary lithium battery?

Source: 2020 - 04 - 01 hits: giving time battery electric bus should use lithium iron phosphate or ternary lithium battery? The safety of new energy vehicles cannot be judged by a single material, safety involves, module, battery, battery vehicle induced factors such as planning and control system, especially the battery production technical level and quality of management level is very big. Domestic new energy automobile enterprises, most of the early use of lithium iron phosphate battery as a source of energy. In the present application in the market, new energy car battery is mainly the lithium iron phosphate batteries, and the ternary lithium ion batteries due to its own advantage to become the first choice for commercial vehicles. In terms of power battery, the application of new energy vehicles for the first time is the lithium iron phosphate batteries and ternary lithium batteries, lithium iron phosphate batteries, pure electric bus lithium iron phosphate battery energy density range is about 87 - battery system 135 wh/kg, continuous mileage of the vehicle is 200 - 576km。 In terms of ternary batteries, electric city bus using ternary ningde era, the energy density of 136 system. 05 wh/kg, the mileage of 450 kilometers. Pure electric bus like lithium iron phosphate batteries, mainly because it safer than ternary lithium batteries. New energy bus capacity is big, in the event of accidents often more damage than the bus. Power battery is considered to be the primary factors influencing the performances of the new energy automotive safety, it is directly related to the battery of open operation, affecting the direction of national policy and speech. So, despite the ternary talent power battery life, also is better than that of lithium iron phosphate battery energy density, but the safety of the bus priority category, industrialization, on the basis of the lithium iron phosphate batteries in our country, higher technical maturity under the setting of pure electric vehicle class still tend to use more safety of the lithium iron phosphate batteries. Abstract: three yuan material power lithium ion battery and lithium iron phosphate ion battery, there is a big security risk, and commercial vehicles ( Especially in commercial vehicles) Member is more, in the event of accident, may bring serious consequences. Therefore, the ministry decided to suspend using ternary lithium ion batteries in electric commercial vehicle.
