Can energy storage lithium batteries and electric vehicle lithium batteries be interchanged?deep cycle solar battery

　　For ordinary friends who do not have much knowledge of lithium batteries, it is considered acceptable. However, for friends who are engaged in lithium batteries or have knowledge of lithium batteries, it depends on the situation, and of course, they will think that it is not acceptable in most cases. What's going on here? What is not suitable for exchanging energy storage lithium batteries with electric vehicle lithium batteries?

　　Firstly, we need to know that the most basic point is that in addition to polymer lithium batteries, iron phosphate lithium batteries, cobalt acid lithium batteries, etc., the most important thing is that there are also power lithium batteries and ordinary lithium batteries. It should be noted that power batteries and ordinary energy storage batteries have certain differences in quality performance standards and raw materials, so if used interchangeably, there will be problems.

　　Energy storage lithium batteries belong to conventional lithium batteries and generally support stable discharge performance within 1C magnification. If exceeded, the battery will easily generate heat and be scrapped due to short circuits.

　　Below, we assume that energy storage lithium batteries (non power type) and electric vehicle lithium batteries have the same capacity, and both belong to the same category as lithium iron phosphate batteries or polymer lithium batteries. Here, we will briefly explain with lithium iron phosphate batteries.

　　The general application scenario of lithium iron phosphate batteries for energy storage is that some conventional electronic devices use electricity, such as information base stations, some 3C electronic products, etc. Their discharge requirements are mostly below 1C magnification. In such cases, the performance of the materials used to manufacture lithium iron phosphate batteries will be relatively poor, such as in terms of separators. Because lithium batteries with low magnification discharge are not easy to generate heat, they are resistant to temperature, The separator is worse than the power type battery, and the natural price is relatively lower.

　　In terms of internal resistance, due to the small discharge current of the battery, the internal resistance is generally higher than that of the power type battery. This means that although the type of battery material used for energy storage lithium batteries and power lithium batteries is the same, the quality of the same material is slightly worse, and the internal resistance is also higher. Therefore, in terms of overall price, generally speaking, Energy storage lithium iron phosphate batteries are cheaper than power lithium iron phosphate batteries.

　　In fact, energy storage lithium batteries also have power types, such as supporting a stable current discharge capacity of around 5C. Therefore, whether energy storage lithium batteries can be interchanged with electric vehicle lithium batteries depends on whether the types of these two batteries are the same, and then whether the batteries have the same capacity. Finally, it also depends on whether the stable discharge current supported by energy storage lithium batteries can meet the requirements of electric vehicle lithium batteries during driving, And whether the maximum allowable current meets the requirements for short-term use of electric vehicles. If all of these are met, is it okay? Of course not. You need to know how to adjust the electric control system of the electric vehicle when replacing the battery.
