0.3 milliohm. Different types of lithium iron phosphate batteries have different internal resistances, which are related to discharge current and temperature. However, the internal resistance of lithium iron phosphate batteries is preferably 0.3. At this value, the internal resistance of the battery is smaller and may be high. Better adapt to the operating needs of lithium iron phosphate batteries, thereby extending the life of the battery.
As lithium batteries age, internal resistance increases. How will this affect the actual battery capacity?
Of course, the lower the internal resistance of the 67.2 volt lithium battery, the better. The closer the internal resistance of your lithium battery is to 0, the lower your loss will be. loss, the greater the power it can provide. The desired actual internal resistance of the battery can be obtained byfollowing formula:
E=V1+V1*r/R1 E=V2+V2*r/R2 V1, V2, R1, R2 are known, solve for E and r. r is the internal resistance of the battery.
The principle is that the internal resistance of the voltmeter must be much greater than R1 and R2.
Of course, the smaller the internal resistance the better, preferably 0, but this is an ideal state. The internal resistance of ordinary lithium batteries is only a few milliohms. The internal resistance of lithium batteries should be as low as possible. The smaller the internal resistance. For batteries, less energy is wasted. And this is helpful for heat production and battery rate.
Physically speaking, this will increase the power consumption of the internal resistance and reduce the capacitance.
As it is assumed that the battery can provide 100 J, the battery itself consumes 50 J, which is equivalent to 50 J of intelligent energy storage.
But the news beatsries have almost no internal resistance consumption.
From a chemical point of view, some reaction substances have undergone an irreversible transformation and can no longer store energy
