A battery simulator power supply is great for bench testing as well as production testing. To simulate a battery, a power supply emulates many of the battery’s characteristics. The most important characteristic is the ability to sink current when the battery simulator is charged. The battery charger drives charging current into a simulated battery.
Elektro-Automatik’s Battery Simulator software makes it possible to simulate both lead-acid and lithium-ion batteries—including their electrical and chemical characteristics—during charge or discharge.
Conventional power supply can only source current, but cannot sink current. Thus a conventional power supply cannot effectively simulate a battery. Figure 1 and 2 show simplified diagrams for the difference between a conventional power supply circuit and a battery simulator power supply.
This type of power supply is called two-quadrant power supply. In contrast, a conventional power supply can only source current when the voltage is positive. A battery simulator may be able to set the simulated battery voltage either remotely via PC or manually. Often battery simulators have built-in voltage and current display and monitoring.
Battery simulator power supply with non-drifting voltage is ideal for bench testing. Especially, when you want the voltage to be constant for the duration (minutes to hours) of the test. A real battery has its own internal impedances called ESR (electric static resistance). When current is draw from the battery, its voltage drops slightly.
Thus, a power supply fundamentally is not equivalent to a battery. Batteries can be modeled as a two-quadrant voltage source along with a series resistance (Fig. 1). The output voltage and the resistance are reprogrammed to simulate the effects of state-of-charge and battery aging.
