What is the relationship between the capacity and voltage of lithium iron phosphate batteries? What is the relationship between the discharge voltage and capacity of lithium iron phosphate batteries? Lithium iron phosphate batteries refer to lithium batteries that use lithium iron phosphate as the positive electrode material. What is the charging voltage and capacity of the lithium iron phosphate battery? The author has answered this problem for everyone. What is the relationship between the voltage and capacity of the lithium iron phosphate battery? The voltage of the lithium iron phosphate battery: the nominal voltage of the lithium iron phosphate battery is 3.2v, the high-end charging voltage is 3.6v, and the low-end discharge voltage is 2.0v. Due to the different quality and technology of the positive electrode, negative electrode data, and electrolyte data used by various manufacturers, there will be some differences in their performance. The charging voltage of the lithium iron phosphate battery pack should be set to 3.65v, the nominal voltage is 3.2v, the maximum charging voltage can be 20% higher than the nominal voltage, but too high voltage will cause damage to the battery, 3.6V voltage lower than this index, no excess Charge phenomenon. The 3.6V voltage is the charging voltage, and both experiments and theories have proved its optimal charging voltage. The discharge voltage value is 2.53.65v, and the maximum charge value can be changed according to customer needs. Lithium iron phosphate battery voltage and capacity 1. Lithium iron phosphate battery charging voltage: 10A standard charge state 25% power voltage point 13.41v: in the charging state, the lithium iron phosphate battery voltage reaches 13.41v, the battery capacity exceeds 25; state of charge Lower battery 50% voltage point 13.51v: In the charging state, the lithium iron phosphate battery voltage reaches 13.51v, and the battery capacity exceeds 50%; the 75% charging voltage point is 13.63v: In the charging state, the lithium iron phosphate battery voltage reaches 13.63v , The battery capacity exceeds 70%. 100% power voltage point in the charging state: In the charging state, the voltage of the lithium iron phosphate battery reaches 14.61v, and the battery capacity reaches 100%. 2. Discharge voltage of lithium iron phosphate battery: 5% of the voltage point corresponding to 0.5c discharge is 11.90v in the discharge state: in the discharge state, the voltage of the lithium iron phosphate battery reaches 11.90v, leaving 5% of the battery capacity. 10% battery voltage point 12.24v in the discharge state: In the discharge state, the voltage of the lithium iron phosphate battery reaches 12.24v, and the remaining 10% power; the battery 25% voltage point in the discharge state 12.55v: The voltage of the lithium iron phosphate battery reaches 12.55 in the discharge state v, 25% of the remaining battery capacity; the voltage point of the 50% power in the discharge state is 12.74v: in the discharge state, the voltage of the lithium iron phosphate battery reaches 12.74v, and the remaining 50% power. In the discharge state, the voltage point of 75% of the power is 12.85v: in the discharge state, the voltage of the lithium iron phosphate battery reaches 12.85v, which is 75% of the remaining power. What is the relationship between the voltage and capacity of a lithium iron phosphate battery? Voltage capacity. JPG1. Generally speaking, the higher the charge and discharge voltage of a lithium iron phosphate battery, the greater its capacity. The charge and discharge voltage of a lithium battery varies with the data. 2. The same lithium iron phosphate battery, under the same capacity, the voltage value changes with the change of the discharge current. The greater the discharge current, the lower the voltage. In the case of no current, the voltage is the highest; 3. The influence of ambient temperature on the battery voltage. The lower the temperature, the lower the voltage of the equal capacity battery; 4. The influence of cycling on the discharge channel of the lithium battery. With the development of cycles, the discharge channels of lithium batteries tend to deteriorate. The discharge channels are reduced. Therefore, the capacity represented by the same voltage also changes accordingly; 5. Different manufacturers and different capacity lithium batteries have slightly different discharge channels.
