A battery simulator (battery emulator) is a programmable source/sink that reproduces battery voltage and current for repeatable testing. It can model battery behavior such as internal resistance/ESR and SoC/SoH-like conditions without needing real cells.

A “battery simulator power supply” is typically a bidirectional programmable DC power supply used to emulate both discharge and charge behavior. AMETEK Programmable Power positions its battery simulation platforms as bidirectional and regenerative for efficient, repeatable testing.

Yes—battery simulation is used to validate battery management systems (BMS) without physical packs. The category positioning highlights use in BMS, converters, and drivetrains testing across industries.

Yes—bidirectional capability helps simulate both battery discharge (source) and battery charging (sink) behavior. i‑BEAM and Mi‑BEAM are described as bidirectional and regenerative platforms (model dependent).

Battery simulation can scale from cell/module-level to pack/system-level depending on required voltage/current/power. Mi‑BEAM is positioned as modular and scalable, i‑BEAM is positioned for higher-power battery simulation with parallel scalability.

Battery simulation software helps run repeatable test scenarios by applying a battery model and controlling simulator output behavior. Mi‑BEAM is positioned as a “complete solution” that includes battery simulation capability and related resources (drivers/software sections vary by product page).

Battery simulation platforms often provide interfaces for automation and test stand integration. i‑BEAM lists options such as Ethernet/VNC, Modbus, CAN, EtherCAT, Profinet, plus integration workflows with LabVIEW and MATLAB/Simulink.

The Battery String Simulator (BSS) is positioned to provide safe, reliable battery power for spacecraft testing and integrated system testing. BSS is described with static and dynamic modes, spreadsheet-based charge tables, and optional sensor simulation for more complete emulation.

Battery simulators emulate battery behavior by controlling voltage, current, and internal resistance to reproduce real operating conditions without physical cells. This supports repeatable testing across modeled conditions like SoC and load-driven voltage sag, AMETEK Programmable Power describes emulation of behaviors including SoC and voltage sag via controlled parameters.

Internal resistance/ESR impacts terminal voltage under load and charge current, so modeling is key for realistic battery simulation. Without ESR modeling, tests may miss real behaviors like voltage sag, and charger/BMS edge conditions; AMETEK’s definition includes internal resistance/ESR reproduction.

Regenerative battery simulation means the system can sink power during charge simulation and return absorbed energy instead of dissipating it as heat, improving efficiency for long tests. AMETEK Programmable Power describes i‑BEAM as regenerative (up to ~96%) and Mi‑BEAM as regenerative (up to ~95%), supporting efficient, repeatable testing.

Choose Mi-BEAM for a modular 4U platform with 80 V to 2,000 V output, current up to ±1,000 A per unit and expansion from 10 kW to multi-megawatt systems. Choose Mi-BEAM Power Rack when the application requires an integrated 42U rack with up to 262.5 kW and ±7,000 A per rack, built-in rack safety features and expansion to 8.6 MW. Choose i-BEAM for customized high-power or multichannel testing with 5 V to 1,500 V output, up to ±1,200 A per system and power up to 650 kW per system, with parallel scalability up to 5 MW. Choose BSS for spacecraft and integrated-system testing that requires battery-string simulation.

Many battery test workflows require dynamic profiles (changing voltage/current over time) to match real operating conditions more accurately than a static power source. i‑BEAM is positioned for advanced, integration-heavy test workflows.

Yes—battery simulation is widely used for BMS validation, including integration-heavy test setups. i‑BEAM lists HIL-relevant interfaces such as CAN, EtherCAT, Profinet, plus integration workflows using LabVIEW and MATLAB/Simulink.

Yes. Mi-BEAM systems scale up to 8.6 MW+ through parallel operation. Mi-BEAM Power Rack provides up to 262.5 kW and ±7,000 A per rack and scales up to 8.6 MW. i-BEAM provides up to 650 kW per system and scales up to 5 MW in parallel.

Battery String Simulator (BSS) is positioned for spacecraft battery simulation, enabling integrated system testing beyond basic two-terminal power behavior. BSS is described with static/dynamic modes, spreadsheet-based charge tables, optional sensor simulators (e.g., thermistor/pressure/heater loads), and remote control via Ethernet/optional GPIB using SCPI format commands.
