High-Power Battery Emulation · Bidirectional DC Testing
High-Power Battery Emulator & Battery Simulator
Test your DUT without waiting for a physical battery pack to reach the required condition. Simulate programmable battery behaviour for inverters, EV charging equipment, PCS and other battery-connected DUTs.
Configure the system around your required voltage, power level, bidirectional power flow and battery-emulation functions.
Voltage and power capability depend on the selected system configuration.
Start Your Test Project
Have a DUT and electrical range?
Send the DUT type, approximate voltage and power. We can review the configuration from there.
Why Battery Emulation
Control the Battery Conditions Your DUT Needs to See
Whether you are replacing a physical battery, developing a new DUT or building a larger test system, battery emulation gives you more control over the electrical conditions used during testing.
Your project does not have to match one fixed test example.
Different DUTs, voltage ranges, power levels, power-flow directions and test objectives can be reviewed around the actual project requirement.
Reach the Required Battery Condition Faster
A physical battery may need to be charged or discharged before the voltage, SOC or operating condition required for the test is available.
Move directly to programmable battery-side conditions according to the DUT and test objective.
Repeat or Change Test Conditions
Development and validation often require one operating condition to be repeated and then changed to another voltage, SOC or load condition.
Configure and reproduce defined operating conditions instead of relying on the changing state of a real battery.
Support Different Power-Flow Scenarios
Depending on the DUT and operating state, the test may require DC power to be supplied, absorbed or transferred in both directions.
Source, sink and bidirectional operating requirements can be reviewed around the actual application.
Have a different DUT, voltage range or test requirement?
Send us what you are testing and the approximate electrical range. We can review the project even if the final specification has not been fully defined yet.
Battery Simulation Capabilities
Simulate the Battery Conditions Your DUT Needs
Go beyond a fixed DC output. Configure battery-side behaviour for different operating states, repeat defined conditions and adapt the simulation around the actual DUT and test objective.
Battery Behaviour → DUT
Reproduce the electrical conditions the DUT needs to see.
Combine programmable battery behaviour with bidirectional DC power operation for development, validation and test-bench applications.
01
OCV–SOC Behaviour
Reproduce battery voltage across simulated states of charge.
Configure the relationship between open-circuit voltage and SOC for different operating conditions.
02
Internal Resistance
Represent battery-side voltage response as current changes.
Configure resistance behaviour for charging, discharging and changing DUT operating conditions.
03
Dynamic SOC
Change simulated battery state as energy flows during testing.
SOC behaviour can change as the DUT draws power from or returns power to the emulator.
04
Custom Battery Curves
Configure battery behaviour around different test requirements.
Battery curves and applicable charge/discharge profiles can be configured or evaluated around the project.
05
Source ↔ Sink Operation
Support tests where DC power needs to flow in either direction.
Supply power to the DUT and absorb returned energy for charge, discharge and regenerative scenarios.
06
Programmable Test Profiles
Build repeatable conditions instead of one fixed operating point.
Defined profiles, operating points and project-specific sequences can be reviewed for the required workflow.
Real Control Interface
Programmable Operating Conditions
Actual HMI examples show programmable profiles and defined operating-point functions. Displayed values represent example operating conditions, not universal system ratings.
Need to reproduce a battery condition not shown above?
Tell us your DUT, approximate voltage and power range, and the battery behaviour or test sequence you want to reproduce. We can evaluate the suitable configuration around the project.

Other Battery-Connected Equipment
If your DUT is not listed here, send the topology, approximate electrical range and what the battery side needs to reproduce.
Your Application Does Not Need to Match This List
Have a different DUT or test architecture?
Send us what the equipment is, the approximate voltage and power range, and what you need to reproduce on the battery side. We can evaluate the project before the final specification is fully defined.
Configuration Fit
Start With Your DUT, Voltage and Power
A battery emulator configuration is selected around the equipment being tested, the required DC range, maximum power and the direction of power flow. You do not need a complete specification to begin.
Your DUT
Tell us what you are testing: inverter, charger, PCS, converter, test bench or another battery-connected device.
DC Voltage Range
Approximate minimum and maximum DC voltage is enough for the first configuration review.
Maximum Power
Provide the expected kW level or approximate peak power requirement.
Power Direction
Tell us whether the DUT draws power, returns energy, or requires bidirectional operation.
Electrical Range & Project Capability
Standard configurations cover a broad DC range, while higher-voltage and higher-power projects can be evaluated according to the system architecture.
Do not stop at the ranges shown above. Send the required operating range and DUT information so the project can be reviewed for a suitable configuration.
Approximate values are enough for an initial review.
DUT + voltage + power + power direction gives us enough information to start discussing the configuration.
Engineering & Verification
Built Around Real Test Requirements
A high-power battery emulator is not selected from one universal specification. The system is configured around the DUT, electrical range, power flow and test objective, then verified before delivery.
Real DC Power Hardware
Cabinet and system configurations are built around the required voltage, power and bidirectional operating requirements.
Factory Verification
Output behaviour, source/sink operation, response, protection functions and control operation can be checked before delivery.
Project-Based Configuration
The recommended solution depends on the actual DUT and test objective, rather than forcing every project into one fixed model.
Factory Verification Can Include
The exact verification plan depends on the selected configuration and project requirements.
Send Your Requirement
DUT, voltage, power and approximate test objective.
Configuration Review
Review system range, power direction and battery-emulation needs.
