Battery Emulation

Besides testing and characterization of batteries, the emulation of electric systems is becoming increasingly important.
To optimize, validate, and evaluate components and applications through reliable and flexible battery simulation, HORIBA has developed X-HVT.

X-HVT simulates the real behavior of:

• Batteries, battery modules, battery packs and battery systems
• Fuel cells, fuel cell stacks and fuel cell systems
• High-voltage wiring systems in vehicles
• 48 V wiring systems in vehicles
• Energy grids
   

With a single unit voltages up to 1500 V, currents up to 2000 A, and outputs up to 1000 kW can be achieved. Higher currents and power levels are possible through parallel configuration. Stored simulation models enable realistic battery emulation. In addition, custom discrete-time, continuous-time, or hybrid Simulink and Stateflow models can be processed.

Thanks to its modular design, X-HVT can be individually customized and configured to meet your testing requirements. It is ideally suited for testing and evaluating charging devices, inverters, and battery management systems (BMS).

Currents up to ±800 A enable the simulation of starter behaviors and start-stop scenarios. Higher values are possible with parallel setups. In addition to constant power, voltage, resistance, and performance modes, switching conditions and alarm limits can also be defined.

Stored simulation models allow for the emulation of:

• Batteries, battery modules, battery packs and battery systems
• Fuel cells, fuel cell stacks and fuel cell systems
• 48 V on-board power supplies in vehicles
   

Custom, time-discrete, time-continuous, or hybrid Simulink and Stateflow models can also be processed.
 

X-HVT is a customizable solution for diverse testing needs and includes:

• State-of-the-art IGBT technology with extremely low noise level
• Parameterized standard and user-specific battery models
• Excellent safety characteristics for Performance Level "d"
• Parameterized control loop architecture for the adjustment to different testing requirements
• Excellent measurement precision and reproducibility
• Fast settling time (t90) of less than 0.3 ms to capture highly dynamic effects
• Efficient automation interfaces, including direct control unit communication and HiL interface
• Manual operation via a modern touch interface
• Flexible installation concepts
