The difference between power lithium battery and capacity lithium battery

With the widespread application of digital products such as mobile phones and computers, lithium batteries, as a very important battery product in these digital products, have been widely used and gradually developed into other fields. There are many kinds of lithium batteries, such as power lithium batteries and capacity lithium batteries. What are the differences between these two types of lithium batteries? Perhaps many people are not very clear. The technical staff will explain to you the power and power of lithium batteries. What are the differences in capacity: Power lithium battery 1. Different voltages In the battery industry, when the voltage rises, the corresponding output voltage will also rise, so that the power lithium battery pack can meet some high-power equipment; direct use in parallel It is the current of the newly added entire battery, and its capacity is affected by the current at the output terminal. Therefore, the direct use of parallel connection is to increase the capacity of lithium batteries. The capacity of the battery connected in this way is usually relatively large, which is the so-called capacitive lithium battery. 2. Use different products. Some large-scale equipment requires a high voltage value, because low-power battery packs cannot operate, so we have to choose power lithium batteries. For example, the electric bicycle we often use, its voltage value is often 48V, related to some of our lives, 48V is not small. So you must use lithium batteries to keep the bike running. But we usually go to some large supermarkets or shopping malls, some sign lights and backup power supplies, because these devices do not consume a lot of power, so we generally use capacitive lithium battery packs, and the applications of the two are different. 3. Different internal resistance The internal resistance of the power lithium battery is smaller than that of the capacity lithium battery. Taking 18650 as an example, a good three-discharge manufacturer usually has a PDC with an internal resistance of about 40. A 5-rate discharge generally does not have a PDC internal resistance of about 20. There is any difference between power lithium battery and lithium battery capacity sharing. In actual use, it is not suitable for the rigid regulations of the connection method of lithium battery packs. Strings and hybrids are often used, although they are not purely link types in a single aspect. Effect, but also combines the advantages of both. This is often the case when using lithium battery packs, because only in this way can lithium battery packs perform better. Before, we have also talked about the differences between power lithium-ion batteries and ordinary batteries, you can combine them to know.
