VES3 high voltage series

Battery simulation and battery tests with VES3

Vehicle Energy Systems VES3 are specially adapted to the requirements at test benches operation. Therefore they include convincing features.

Next to high dynamics, these energy systems are characterised by a wide control range and extensive control concept. This allows them to operate various loads with capacitive, ohmic and inductive characteristics. All hybrid components can be tested and simulated with a vehicle energy system. To double the power capacity, two systems can be connected and operated in parallel.

Automation and HIL-Simulation

For the communication between measuring equipment and automation systems we provide all common bus systems. This also covers a fast EtherCAT interface.

For simulation purposes you have the choice of using onboard models or the possibility to integrate own models. These models can be calculated on FGPA boards with high sampling rate. Therewith, the behaviour of simulated components will be calculated in real time and forwarded to the vehicle energy system as current or voltage reference value. For that purposes, a high speed interface with 40 kHz data sampling rate is available. The MATLAB Toolchain supports model creating with MATLAB/SIMULINK.
