用于 EIS 测试的电池仿真软件 — BatterySim Studio

BatterySim Studio 是 Impedyme 的旗舰 电池仿真软件 ,面向设计、验证和认证用于电动汽车、固定式储能和高性能电力电子的锂离子电芯、模组和电池包的工程师。它是一个电池仿真软件平台,将 实时硬件在环(HIL) 与 功率硬件在环(Power-HIL)仿真 与集成的 电化学阻抗谱(EIS)、自动化等效电路模型(ECM)拟合以及实时故障诊断结合在单一应用中。BatterySim Studio 基于 Impedyme 的 FPGA CHP(HIL 与功率相结合)平台 和 Power HIL Studio 环境构建,以单一的 MATLAB/Simulink 原生电池仿真软件工作区取代碎片化的工具链——一个工具用于电芯建模,另一个用于阻抗测量,再一个用于 BMS 测试——其规模可从台式纽扣电池研究扩展到兆瓦级牵引电池组。

什么是 BatterySim Studio 电池仿真软件?

BatterySim Studio 是一款基于 Windows 的电池仿真软件和电池仿真应用程序,运行于 Impedyme 的 Power HIL Studio 和 CHP 硬件。作为一个完整的电池仿真软件环境,它让工程师能够在电芯、模组和电池包层面运行基于物理的锂离子、LFP、NMC、NCA 及新兴固态电池化学体系的实时仿真;在低于 1 Hz 到 20 kHz 的频率范围内进行高保真 EIS 测量,并自动绘制奈奎斯特图和波特图;自动拟合等效电路模型——Randles、Thevenin、双极化和高阶 RC 网络,包括带恒相位元件和 Warburg 扩散的分数阶 ECM——并进行随 SOC、SOH 和温度变化的参数化;在闭环功率条件下向 BMS、逆变器、车载充电器或 DC-DC 变换器仿真真实电池;并注入诸如电芯不平衡、微短路、传感器故障、过压和过温等故障,同时实时捕获被测设备的响应。

大多数电池仿真软件只占据单一细分领域:要么是基于物理的离线设计仿真,要么是采用集总电芯模型的简单电源控制。BatterySim Studio 则专为工作流程中的验证和仿真阶段而设计——它将表征、建模、仿真和诊断整合在一起,使工程师不再需要在各个独立工具之间传输数据。

What Makes BatterySim Studio Stand Out as Battery Simulation Software?

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

In conventional HIL, a simulated battery delivers signal-level sensor values to a BMS ECU. BatterySim Studio supports this out of the box. Where this battery simulation software goes further is Power-HIL: by routing the real-time model through a bidirectional regenerative converter, the emulated pack delivers real current and voltage to the device under test — letting engineers validate BMS logic alongside contactor, pre-charge, on-board charger, DC-DC converter, and motor-inverter behavior under production electrical conditions.

Applications and Use Cases

EV Battery Pack Validation

Teams use this battery simulation software to validate BMS firmware, contactor logic, and fast-charge behavior against an emulated 400 V or 800 V traction pack, running hundreds of fault permutations per night without a physical battery.
Energy Storage icon

Energy Storage Systems

Megawatt-class Power-HIL lets this battery simulation software emulate utility-scale racks, testing grid-tied inverters and EMS controllers against real conditions without staging a costly real battery yard on the lab floor.
Research icon

Academic and Industrial Research

Universities use this battery simulation software to study fractional-order modeling with MATLAB/Simulink workflows dropping in with minimal re-implementation.
Safety Testing icon

Safety Testing

Internal-short, over-charge, over-discharge, and ground-fault scenarios are scripted in this battery simulation software and replayed safely thousands of times, because the battery is fully emulated rather than physical.

Battery Modeling Approaches BatterySim Studio Supports

Good battery simulation software should not lock engineers into a single model fidelity. BatterySim Studio works across the full modeling pyramid: empirical and lookup models for the fastest real-time loops; Equivalent Circuit Models — Thevenin, dual-polarization, n-th order RC, Randles, and fractional-order ECMs — fitted directly from EIS data; physics-based reduced-order models including the Single Particle Model and SPMe; Doyle-Fuller-Newman (DFN / P2D) models for offline parameterization, with reduced-order outputs deployed to the real-time engine; and coupled electro-thermal models so heat generation evolves consistently with the electrical state.

Frequently Asked Questions

What is BatterySim Studio used for?
It is used to test battery behavior, analyze impedance data, validate BMS algorithms, detect faults, and support EV, energy storage, and research applications.
How is BatterySim Studio different from other battery simulation software?
simulation software handles only one stage of the workflow. BatterySim Studio unifies physics-aware modeling, integrated EIS, automated ECM fitting, and real-time Power-HIL emulation in a single interface.
What kinds of faults can BatterySim Studio detect?
It can help identify high internal resistance, Nyquist intercept shifts, phase discontinuity, coherence problems, and time-domain instability.
Is BatterySim Studio only for battery simulation?
No. It also supports EIS analysis, fault detection, battery model fitting, and real-time diagnostics, making it a broader engineering tool.
Who should use BatterySim Studio?
It is ideal for EV developers, battery engineers, BMS teams, energy storage labs, and researchers working on impedance-based battery analysis.
