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.
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. Therefore, the current is flowing into the simulator power supply.
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.
Use a Power Supply to Emulate a Battery A power supply can be used for the programmable battery. However, a typical power supply has three characteristics that make it unlike a battery and, therefore, unsuitable for battery emulation. First, a power supply tends to maintain very low and constant output impedance.
It may be possible to use an electronic load to to simulate a batter if the load can be controlled by a computer. The computer needs to read the current and provide a 'load' profile that simulates the battery charging profile. The all in one solution provide this for you.

For testing these electronic devices, a battery simulator or emulator is often needed. For example a lithium ion battery emulator can easily vary the voltage to simulate a battery is being charged or discharged. This eliminates hours of test time. A battery simulator power supply is great for bench testing as well as production testing.
