Is the voltage of the lithium iron phosphate battery 3.2V or 3.65V?

The 3.2V lithium iron phosphate battery refers to the nominal voltage of the battery cell, and also the discharge platform voltage of the cell. To put it bluntly, the cell is fully charged and discharged to the end of the discharge (we often say that the voltage is dead). Uniform voltage, as for the voltage of 3.65V, it refers to the no-load voltage when the lithium iron phosphate battery is fully charged, that is to say, the two voltages refer to the voltage of the battery, and the voltage of a single battery of the same battery is the same The difference is the capacity. The capacity depends on the size of the battery cell and the equipment and Ru0026D technical strength of the lithium iron phosphate battery processing manufacturer. Generally strong manufacturers, such as the iron phosphate of the same size and specifications processed by the Gripp battery Lithium battery cell capacity can be made higher, of course, the price will be more expensive. So what are the 12V, 12V, 24V to 72V of lithium iron phosphate batteries? In fact, the statement that the voltage exceeds 3.65V is already talking about batteries, not batteries. Regardless of whether it is 12V, 24V or higher voltage of lithium iron phosphate battery, it is realized by the series connection of battery cells. For example, 12V, it is necessary to connect 4 3.2V battery cells in series, which is 3.2V+3.2V+3.2V+ 3.2Vu003d12.8V. The series connection method is as follows: the battery series diagram does see the standard integer voltage volts on the market, most of which will be a little higher, unless it is strictly required for the voltage to be used, some circuit boards will be equipped and adjusted to The desired voltage in volts. Modular batteries, like other higher volt-voltage batteries, are currently basically developing towards modular batteries, that is, smart batteries with bms management. These battery packs range from 12V to 72V, and they are all realized by connecting a single battery cell in series. Of course, different types of battery cells can achieve different voltages in series. For example, the battery cell voltage of a nickel-hydrogen battery is 1.2V. The voltage of the series connection is 2.4V, 3.6V, 4.8V12V. On the top, a more mature battery protection board is needed. Fewer companies make high-voltage nickel-metal hydride batteries; polymer lithium battery cell voltage is 3.7V , The series voltage is about 7.4V, 11.1V, 14.8V to 70V, and safety risks are prone to appear upwards, because the consistency of polymer lithium battery cells is worse than other cells. The voltage of the iron phosphate battery cell is 3.2V, and the voltage in series is 6.4V, 9.6V, 12.8V to 70V or less. This is similar to the polymer lithium battery cell, but it is better than the polymer lithium battery in terms of cell consistency. . As for the capacity of batteries or battery packs, there are many changes. You can make batteries with corresponding capacity according to the needs of electrical equipment. Of course, the capacity of cells of a certain size is also limited. If you want to increase the capacity, you have to connect cells or batteries in parallel. , This is also limited in number, as far as the current technology is concerned, it can achieve 12 to 18 parallel numbers.
