Hardware-in-the-Loop

Real-time testing for modern control systems
Hardware-in-the-Loop (HiL) is a modern testing method in which control units or electronic components are tested within a realistically simulated environment. Signals from sensors, cameras, or other system components are virtually generated and transmitted to the test object. This allows functions and responses to be tested under practical conditions, even if the actual complete system is not available.

The bidirectional operation enables the simulation of various operating states. Developers benefit from a safe, reproducible, and efficient testing environment – without the need for charging cycles or thermal conditioning of real batteries.

Battery Emulator for HiL Applications
The BeXema battery emulator is designed for use in HiL environments. It accurately replicates the electrical behavior of 12V, 24V, and 48V batteries and can be directly integrated with real components such as generators, inverters, DC/DC converters, energy storage systems, and electric motors.
