The three commonly used batteries of new energy vehicles are ternary lithium battery, lithium iron phosphate battery, and nickel metal hydride battery, and the current more common and popular recognition is ternary lithium battery and lithium iron phosphate battery. So, how to distinguish the new energy vehicle battery is ternary lithium battery or lithium iron phosphate battery? The following is a brief introduction to the method.
For the average consumer, the easiest way to tell whether a battery is lithium terihydric or lithium iron phosphate is to look at the battery data in the vehicle configuration sheet, which is usually labeled by the manufacturer as the battery type.
Meanwhile, it can also be distinguished by looking at the data of the power battery system on the body nameplate. For example, Chery Xiaoant, Wuling Hongguang MINI EV and other models, there are lithium iron phosphate version and lithium ternary version.
In addition, compared with lithium iron phosphate battery, lithium lithium three battery has higher energy density and better low-temperature discharge performance, while lithium iron phosphate is more superior in life, manufacturing cost and safety. If you find yourself buying a long endurance model, or in the winter low temperature environment, the endurance attenuation is less than other models, then nine times out of ten is the three-way lithium battery, on the contrary is the lithium iron phosphate battery.
Because the power battery pack is difficult to distinguish between ternary lithium battery and lithium iron phosphate battery by observing the appearance, so in addition to the above methods, to distinguish ternary lithium battery and lithium iron phosphate battery, you can only use professional instruments to measure the voltage, current and other data of the battery pack.
The characteristics of ternary lithium batteries: ternary lithium batteries are characterized by good low-temperature performance, the ultimate operating temperature of -30 degrees. But its disadvantage is the low thermal runaway temperature, only 200 degrees, for hotter areas, prone to spontaneous combustion phenomenon.
Characteristics of lithium iron phosphate: lithium iron phosphate battery has a long history of development, he is characterized by good stability and high thermal runaway temperature, which can reach 800 degrees. That is, the temperature does not reach 800 degrees, lithium iron phosphate will not catch fire. Only it is more afraid of cold, in colder temperatures, the battery decay will be more powerful.
