The voltage of Pacific Automotive Network iron phosphate battery cell is 3.2V and the series voltage is 6.4V, 9.6V, 12.8V at 70 V. It is similar to the lithium polymer battery cell, but the. The battery cell is the same. The performance is better than lithium polymer batteries.
3.2V lithium iron phosphate battery refers to the rated voltage of the battery cell, which is also the discharge platform voltage of the cell. To put it bluntly, this means that the cell starts to discharge when it is. fully charged and ends when the discharge ends (often called power-off) the average voltage of this process As for the voltage of 3.65 V, it refers to the no-load voltage of the lithium iron phosphate battery when it East. fully charged. In other words, these two voltages refer to the core voltage of the batterie, while the voltage of single battery of the same type of battery is the same, the difference is the capacity. The capacity depends on the size of. the battery cell and R&D equipment and technical force of lithium iron phosphate battery manufacturer. Generally, high resistance manufacturers, such as Grepow batteries, lithium iron phosphate batteries of the same size may have higher capacity, but of course the price will be. be more expensive.
So, what are 12V, 12V, 24V and 72V lithium iron phosphate batteries? In fact, the claim that the voltage exceeds 3.65 V already refers to the battery and not the battery cell. Whether it is a lithium iron phosphate battery voltage of 12V, 24V or higher, it is obtained by connecting cells in series. For example, 12V means connecting four 3.2V cells in series, or 3.2V + 3.2V + 3.2V + 3.2V = 12.8. V. Open the appon Baidu to view the high-definition battery cell series diagram. In fact, if you see integer voltages on the market, most of them will be a little higher, unless the power consumption strictly requires the voltage, some circuit boards will. be equipped to adjust it. Voltage required.
Like other batteries with higher volts, they are essentially evolving towards modular batteries, that is to say intelligent batteries with BMS management. These batteries range from 12V to 72V and are all made by connecting a single cell in series. Of course, different cell types have different voltages in series. For example, the cell voltage of a nickel-metal hydride battery is 1.2 V. The series voltages are 2.4 V, 3.6 V, 4.8 V, and 12 V. As you increase, you need a more mature battery protection board. Few companies make bhigh voltage nickel-metal hydride batteries. The voltage of lithium polymer battery cells is 3.7. V., the series voltages are approximately 7.4 V, 11.1 V, 14.8 V and 70 V. When they increase, safety hazards are likely to arise, because the consistency of the cells of lithium polymer battery is worse than that of other cells. The iron phosphate battery cell voltage is 3.2V, and the series voltage is 6.4V, 9.6V, 12.8V to 70V. This is similar to the battery cell lithium polymer battery, but the cell consistency is better than lithium polymer battery. .
As for the capacity of batteries or battery packs, they are constantly changing. Batteries with corresponding capacities can be manufactured according to the needs of electrical equipment. Of course, the capacity of cells of a certain size is. also limited. If you want to increasenter the capacity, only the cells or batteries need to be connected in parallel. This is also limited in quantity. As far as current technology is concerned, parallel numbers from 12 to 18 can be obtained.

1. The working voltage platform of lithium iron phosphate battery is
< strong> 3.65V.
According to the query on Sohu.com, The full voltage of lithium iron phosphate battery cell is 3.65V and the end of discharge voltage is 2.0V in order to protect the service life of. the battery cell, the battery manufacturer defines that the termination voltage will be higher than 2.0V. Due to the characteristics of the battery chemical material itself, the energy density of lithium iron batteries is lower than that of lithium polymer batteries, but the safety performance is morehigh and the price is lower.
Hello, what you are asking is 1. What is the operating voltage platform of the lithium iron phosphate battery? 1. The operating voltage platform of lithium iron phosphate battery is between 3.2 and 3.3 volts. Lithium iron phosphate battery (LFP battery) is a lithium-ion battery with an operating voltage platform typically between 3.2 and 3.3 volts. In other words, when an LFP battery is charging, its voltage typically reaches around 3.6 volts (around 100% charge), and when discharging, its voltage gradually decreases until it depletes at around 2.5 volts (approximately 100% charge). state of charge). During the whole process, the operating voltage platform of the LFP battery will remain between 3.2 and 3.3 volts.
