Battery Test Station HPDC 1000 BattTest
The HPDC high-voltage energy system is used to test components of modern vehicle drive concepts in the field of E-Mobility.
The system is operated in two-quadrant mode (source / sink). The HPDC BattTest system is connected to the DC link. Due to the self-sufficient energy supply within the test facility only the losses are incurred as energy consumption during stationary operation. Figuratively speaking, the energy flows in a circuit.
The future oriented, modular, compact AIP System design offers both, IGBT and SIC technology, and AIP can equip the power electronics with the technology, as required.
Multi-channel design of the BattSim / BattTest systems
- Systems can be designed as 2-channel with a total of up to 4 DC outputs, of which 2 DC outputs can be used simultaneously
- Relevant e.g. for test runs with front axle/rear axle or additional charging function
Advantages of the DC intermediate circuit
- Cost savings
- Reduction of the required AC connected load
- Utilization of the simultaneity factor for efficient test system operation
- Compact system design
- Demand-oriented power distribution to individual test systems
- Reliability of the DC-side supply
The HPDC BattTest consists of a feed/feedback unit, the power fields, a control unit and a heat exchanger unit. The feed unit is used to provide the required power supply for the power modules. A control cabinet field is equipped with 2 power modules of 100 kW each.
