BatterySim Studio – Advanced Battery Simulation Software for EIS Testing
BatterySim Studio is Impedyme’s dedicated battery simulation software for characterizing electrochemical impedance, emulating real-world battery behavior, and diagnosing faults across cells, modules, and packs. It is built on Impedyme’s Power HIL Studio 与 CHP platforms, combining real-time 真硬件在环(Hardware-in-the-Loop, HIL) and Power-HIL capabilities with advanced Electrochemical Impedance Spectroscopy (EIS) analysis and equivalent circuit modeling (ECM).
BatterySim Studio sits at the center of Impedyme’s battery emulator ecosystem, turning raw hardware capability into an intuitive, diagnostic-rich environment for engineers working on EVs, energy storage, and power electronics systems. By integrating Nyquist and Bode plotting, fault signatures, and ECM fitting into one unified interface, it functions as a complete battery simulation software stack rather than a simple visualization tool.
Why Battery Simulation Software is Critical in Modern Energy Systems
The global transition to electrification has significantly increased the complexity of battery systems.
Battery packs now involve:
- Hundreds or thousands of cells
- Sophisticated battery management systems
- Dynamic thermal and electrical interactions
- Fast charging technologies
Testing these systems with physical batteries alone is inefficient.
Battery simulation software solves this problem by creating digital models of battery behavior, enabling engineers to test systems safely and quickly.
According to industry research, simulation tools can reduce development costs and testing time significantly by allowing engineers to evaluate designs digitally before building prototypes.
Core Capabilities
Real-Time Battery Emulation
BatterySim Studio deploys high-fidelity battery models on FPGA-based CHP platforms, achieving nanosecond time steps and high bandwidth for closed-loop testing. It supports multiple chemistries (Li-ion, NMC, LFP, NCA) and scales from single cells to full packs.
Control and Protection Validation
Real-time emulation enables engineers to test BMS firmware under dynamic conditions, validate protection thresholds (overvoltage, undervoltage, overcurrent, overtemperature), and evaluate control strategies in inverters, DC/DC converters, and onboard chargers safely and repeatably.
Integrated EIS Testing and Analysis
BatterySim Studio performs wideband EIS from sub-Hz up to ~20 kHz with micro-ohm accuracy. It supports fast multisine and PRBS excitation and automatically generates Nyquist and Bode plots within the interface.
Equivalent Circuit Model (ECM) Fitting
The platform converts EIS measurements into compact ECM models using RC branches, Warburg elements, or fractional-order components. These models enable accurate SOC, SOH, and aging-aware simulations for real-time and system-level studies.
Diagnostics and Fault Detection
Built-in diagnostics translate impedance data into clear health indicators, detecting issues such as internal resistance growth, contact loss, and measurement instability, with real-time pass/fail feedback.
Custom Test Profiles and Automation
Users can define voltage, current, frequency sweeps, and protection limits, then automate testing via MATLAB/Simulink integration. This supports batch testing, SOC-based sweeps, automated logging, and report generation.

What Makes BatterySim Studio Stand Out as Battery Simulation Software?

Fusion of real‑time emulation and EIS
2
Automation and openness
3
Tight hardware integration
BatterySim Studio and Hardware-in-the-Loop Testing
BatterySim Studio operates within a Hardware-in-the-Loop (HIL) and Power-Hardware-in-the-Loop (PHIL) environment.
These testing environments connect real hardware devices (such as inverters, controllers, or BMS systems) to simulated battery models.
The result is a closed-loop testing system where engineers can evaluate:
- Battery behavior
- Power electronics interaction
- Control system performance
PHIL systems allow real electrical power exchange between simulation and hardware, enabling highly realistic testing conditions.
