Iron phosphate lithium ion battery pack capacity:
Lithium-ion battery pack capacity is one of the critical performance indicators to measure the performance of the battery. It means that under certain conditions (discharge rate, temperature, termination voltage, etc.) the battery is released (JS-150D can be used for discharge detection), that is, the capacity of the battery, usually in hours. The capacity of lithium-ion battery is divided into actual capacity, theoretical capacity and rated capacity according to different conditions. The calculation formula of battery capacity C is C= T0IT1DT, and the battery is divided into positive and negative electrodes.
Lithium iron phosphate battery voltage:
Lithium-ion iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a cathode material. The cathode materials of lithium ion battery include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate and so on.
What is the relationship between voltage and capacity of lithium-ion iron phosphate battery pack?
Generally speaking, the higher the charge and discharge voltage of a lithium ion iron phosphate battery pack, the greater its capacity will be. The charging and discharging voltages of lithium-ion batteries of different materials are different, and the lowest is lithium-ion batteries of iron phosphate. As the capacity decreases, the voltage decreases, and the capacity becomes very small when the voltage falls below the rated value.
1. In the same battery, under the condition of the same residual capacity, the voltage value will change due to the discharge current. The greater the discharge current, the lower the voltage. The voltage is the highest in the absence of current.
2. The influence of ambient temperature on the voltage of the lithium ion battery pack. The lower the temperature, the lower the voltage of the battery with the same capacity.
3. Influence of cycle on battery discharge platform. With the progress of cycle, the discharge platform of lithium-ion battery tends to deteriorate. Discharge platform lowered. So the capacity represented by the same voltage has changed accordingly.
4. Lithium ion batteries of different manufacturers and different capacities have slightly different discharge platforms.
5. The discharge platforms of lithium ion batteries with different types of electrode materials are quite different. The discharge platforms of lithium cobalt and lithium manganese are completely different.
