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.
A battery simulator, also known as a battery emulator, is a bi-directional power supply that simulates the operation of a battery. The voltage and current output of a battery vary depending on the load connected to it (power consumption) and its remaining capacity (State Of Charge, SOC). A battery simulator simulates this.
The battery simulation operates based on the I-V curve characteristics, which are the basic characteristics of a battery. Furthermore, by setting the I-V curve characteristics according to the remaining capacity (SOC) % of the battery, it is possible to simulate a more realistic battery operation.
Battery estimation procedure. A state estimation procedure can be subsequently performed with the battery model built and parameters determined. A number of nonlinear estimation algorithms have presented reliable adaptivity in predicting the state of the battery, classifying it as filter-based and observer-based methods [101, 102].
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.
