Research and development of electrified powertrains on the powertrain test bench
Battery simulator
The increasing number of electrified vehicles requires a high-performance, flexible test environment for research and development purposes. In the case of the powertrain test bench, this means a necessary expansion to include a system that represents the interface to the actual vehicle high-voltage battery. This DC voltage source can emulate the behaviour of a real HV battery, e.g. by regulating the voltage, current or power (so-called battery simulator). In addition, it is possible to implement battery models that can be used in highly dynamic test bench operation.
The battery simulator from the company HORIBA FuelCon represents a high-performance solution based on IGBT inverter technology. The maximum power is 250 kW nominal, the limit ranges for current and voltage regulation are 1,000 V and 1,000 A respectively. In this way, testing of all today's common DUTs is possible in this power range, since typical HV system voltages are in the range of approx. 350-800 V. It can be assumed that, due to the Low Voltage Directive 2014/35/EU, the system voltages of future DUTs could increase to a maximum of 1,500 V DC, the economic viability of which must, however, be examined. The option of connecting the battery simulator in parallel with another system also makes it possible to increase the power that can be called up to approx. 450 kW. This option is intended for the operation of the test bench in the vehicle test centre.
With the help of the battery simulator, in addition to the previously completed expansion with a real-time simulation platform with IPG CarMaker/TestBed, another important component has been realised at the powertrain test stand, which significantly expands the possibilities for research and development, teaching and carrying out student work.
