How to distinguish the battery of new energy vehicles from ternary lithium battery or lithium iron phosphate battery?

Three commonly used batteries for new energy vehicles are ternary lithium battery, lithium iron phosphate battery, and nickel metal hydride battery. At present, ternary lithium battery and lithium iron phosphate battery are more common and highly recognized by the public. How to distinguish the battery of new energy vehicles from ternary lithium battery or lithium iron phosphate battery? The following is a brief introduction to the method.

For ordinary consumers, the easiest way to distinguish whether the battery is lithium ternary or lithium iron phosphate is to view the battery data in the vehicle configuration table. Usually, manufacturers will mark the battery type in the battery information.

It can also be distinguished by viewing the data of the power battery system on the body nameplate.

By comparing the data on the body nameplates of the two vehicles, it can be found that the battery rated voltage of the lithium iron phosphate version is higher than that of the lithium ternary version, and the battery rated capacity of the lithium ternary version is higher than that of the lithium iron phosphate version.

In addition, compared with ternary lithium battery and lithium iron phosphate battery, ternary lithium battery has higher energy density and better low-temperature discharge performance, while lithium iron phosphate battery is superior in terms of life, manufacturing cost and safety. If you find that you are buying a long endurance vehicle, or that the endurance decay is less than that of other vehicles in the low temperature environment in winter, then in nine cases out of ten, it is a ternary lithium battery, otherwise it is a lithium iron phosphate battery.

Since it is difficult to distinguish the power battery pack from the lithium iron phosphate battery by observing its appearance, in addition to the above methods, if you want to distinguish the lithium iron phosphate battery from the lithium iron phosphate battery, you can only use professional instruments to measure the voltage, current and other data of the battery pack.

eatures of the ternary lithium battery: The ternary lithium battery is characterized by good low-temperature performance, and the limiting operating temperature can reach - 30 ℃. However, its disadvantage is that the temperature of thermal runaway is low, only over 200 degrees. For relatively hot areas, spontaneous combustion is easy to occur.

Features of lithium iron phosphate: lithium iron phosphate battery has a long history of development. It is characterized by good stability and high temperature of thermal runaway, which can reach 800 ℃. In other words, if the temperature does not reach 800 degrees, the lithium iron phosphate battery will not catch fire. But it is afraid of cold. In cold places, the battery will decay more severely.
