Figure 5-11 Charging resistance versus state of chargeAs can be seen the internal resistances of the battery are increased as the state of chargeof the battery decrease. In higher temperatures the internal resistance is less because ofthe free movement of the electrons in the electrolyte.5.6.3 CapacitorIn order to consider the transient behavior of the battery, the value of the capacitor mustbe measured. To find the capacitor, the voltage transient happening during transition fromone load to another load is observed. A circuit model as shown in figure 5-11 is used .Atfirst load R 1 +R 2 is connected. Then the load is switched to only R 1 .The voltage behaviorof battery is shown in figure 5-12. The transient time between V 1 , when R 1 +R 2 isconnected and V b , when R 1 is connected is measured , τ, and according to followingequation the value of capacitor is calculated.0.63τ = ( R + R C( 5-14)1 int)135
