The DC battery simulator serves as a replacement for the high-voltage vehicle battery for operating the vehicle under almost real conditions on vehicle test benches (reproducible road driving simulation). The system is operated in 2-quadrant operation (source/sink).

The DC battery simulator is preferably connected to the AFE converter (energy control cabinet) of an existing test bench system. By integrating (expanding) the DC battery simulator into the existing test bench infrastructure, costs can be saved accordingly. If the connection to an existing system is not possible, an extra DC link feed unit can also be supplied.

Replacement for the high-voltage vehicle battery for operating the vehicle under almost real conditions on vehicle test benches.

Applications

• Simulation of the vehicle battery for endurance as well as full vehicle performance tests
• Highly dynamic performance / load tests of electric drive systems

Advantages

• Modular, expandable power range from 200 … 1,200 kW
• Connection to the existing intermediate circuit of the motor converter of the test bench
  → no additional feed necessary
• Highly dynamic and precisely regulated power electronics
• High efficiency
• Very compact design (300 kW per power field)
• Integration into the existing security matrix

Example: 600 kW HPDC-BattSim Energy System in Connection with a 4WD Chassis Dynamometer
