A battery simulator can operate to provide different outputs. These outputs provide different characteristics related to how a device under test operates. In an example, a controller such as an electronic control module (ECM) or battery energy control module (BECM) can be tested. The battery simulator may provide different modes, e.g., a high current mode or a voltage change over time mode. A traction battery simulator may include a controller, analog output circuitry being controlled by the controller to output test current and test voltage, and switching circuitry connected to the analog output circuitry that has a first state and a second state. The first state is to provide an increased change in voltage over change in time relative to the second state. The second state is to provide an increased capacitance over the first state.
