Purchase, delivery, construction and operation of a Power Hardware in the Loop Simulator (Power-HiL).

Purchase, delivery, construction and operation of a Power Hardware in the Loop Simulator (Power-HiL).

Essentially, the power HiL consists of two emulators, an AC voltage emulator (AC emulator) and a DC emulator (DC emulator). With the AC emulator, for example, the behavior of a distribution network or an electric motor can be simulated at the power level. The DC emulator, on the other hand, emulates the behavior of a vehicle or backup battery, for example. Both emulators should be able to be operated both as a load and as a source. The behavior and properties of the emulators are defined at the signal level by real-time simulation models. The coupling between the signal and power level is ideally done via fast FPGA-based interfaces.

The Power-HiL should be able to map at least the following two applications:

1. Simulation at the power level of the charging and discharging process of vehicle batteries:

a. The AC emulator simulates the distribution network at the power level

b. The DC emulator simulates a vehicle battery at the power level

c. The test object is a bidirectional charging station including communication protocols and control/regulation. The test object is not the subject of the tender and is provided by the client, whereby the provision of common communication protocols (ISO 15118, DIN SPEC 70121, CHAdeMO and GB/T 27930) for charging stations would be advantageous.

2. Simulation of electric or hybrid vehicles at the power level:

a. The AC emulator simulates an electric motor at the power level

b. The DC emulator simulates a vehicle battery at the power level

c. The test object is an inverter incl. control/regulation. The candidate is not the subject of the invitation to tender and is provided by the client.

d. Ability to update software products when new versions are released.

e. Provision of common communication protocols (ISO 15118, DIN SPEC 70121, CHAdeMO and GB/T 27930) for charging stations.
