5 Effective Internal Impedance Battery impedance is dependent on temperature, its state of charge,and the load frequency. The effectiveinternal impedance is lower for a fullycharged battery than it is for a dis-charged one. Having a low internalresistance is very important when thebattery must suppo...

6 Miscellaneous Tests In addition to the tests already men-tioned, there are also other miscella-neous tests performed on nickel-cadmium batteries. These tests usuallyinvolve high rate charge and/or discharge. High rate discharge and charge ofnickel-cadmium batteries is possiblewith today’s new and ...

7 From the various tests described so far, we can see some commonrequirements for test equipment. Allthe tests require a discharge cycleusing a constant current. A constantdischarge current cannot be attainedwith a simple resistor because thebattery voltage changes as current isdrawn from it. An act...

Agilent Technologies Electronic Loads are ideally suited for batterytest applications. Their many featuresmake the test system easy to config-ure and provide safe, reliable, andrepeatable operation. The Agilent 6060A Electronic Loadand 6050A Electronic Load mainframehave the required constant-curren...
