Battery Testing

The Dynaload is used to test batteries by both analyzing life cycle and establishing the V/I characteristics. The load is operated in the constant current mode which freezes one of the variables when calculating the battery's power level. Some batteries require exotic waveform testing in order to simulate real life uses. This is accomplished by using the Dynaload’s internal pulse generator. Many different waveforms can be created through the use of variable current levels, frequency, duty cycle, and slew rate.

The load may be controlled through the analog remote programming input for situations where the required waveforms are extremely complex. This input, scaled 0 to 10 volts, is directly proportional to the selected full-scale current.

The constant power mode is used to test batteries designed for UPS backup systems. This mode emulates the changing current demand as the bat tery voltage decays. These are the characteristics of both DC to DC converters and inverter input simulations.
