BATTERY MODELLING & SIMULATION SERVICES

Physics-based battery simulation, from particles to cells.

We connect particle-scale electrochemistry to full-cell multiphysics, and use it to design fast-charge protocols, predict ageing, and build the simulation and data workflows your engineers work in every day.

从颗粒到电芯的机理级电池仿真

我们把颗粒尺度的电化学机理与电芯级多物理场模型打通,用于快充协议设计、老化与寿命预测,并为客户搭建工程师日常使用的仿真与数据工作流。

电芯级多物理场

电-热-力耦合模型:极耳与散热设计、温升,以及真实工况下的性能表现。

The three scales share one parameter set: values calibrated at the particle scale carry into the electrode and cell models, so a change in formulation or process stays traceable through to cell-level performance.

三个尺度共用一套参数体系:颗粒尺度标定的参数直接进入电极与电芯模型,配方或工艺的改动可以一路追溯到电芯性能。

Ask your cells a question向你的电芯提问

MCP SERVER — BUILT ON YOUR OWN MEASURED DATA

It lets a battery engineer ask questions about cells in plain English and get answers computed from the actual measured data.

让电池工程师用自然语言提问,答案全部由真实测量数据计算得出。

THE PROBLEM IT SOLVES

The information needed to judge a cell is scattered — raw cycler files in S3, a measurement database, a tracker spreadsheet, and the Quality team's workbook. Answering “is this cell aging badly, and why?” used to mean opening four systems and doing the analysis by hand.

判断一颗电芯所需的信息是分散的:S3 里的原始循环文件、测量数据库、跟踪表格,以及质量团队的工作簿。要回答“这颗电芯老化是否异常、原因是什么”,过去要打开四个系统并手工分析。

WHAT IT DOES

It reads the raw test files and interprets them: segments them into meaningful events (formation, cycling, rate tests, pulses), then describes what happened in engineering language — where capacity was stable, where it started declining, whether there's a knee, whether the impedance is growing faster than the capacity is fading. It cross-links that to how the cell was built and what the Quality inspections found, and it can compare a cell against similar ones from history.

它读取原始测试文件并加以解释:先切分为有意义的事件(化成、循环、倍率测试、脉冲),再用工程语言描述发生了什么——容量在哪一段稳定、从哪里开始衰减、是否出现拐点、阻抗增长是否快于容量衰减。它把这些与电芯的制造信息、质量检验结果交叉关联,并可与历史上相似的电芯做对比。

The MCP brief in chat next to the interactive dashboard: capacity retention of cell C-0417 against a 22-cell cohort, DCIR growth, and the lot's electrolyte fill-weight distribution.
TWO WAYS IT ANSWERS

A short written brief in chat — decision-ready sentences, not data dumps — and an interactive dashboard for looking at the curves.

一是对话里的简短结论——可直接用于决策的句子,而不是数据堆叠;二是用于查看曲线的交互式看板。

TWO AUDIENCES

R&D engineers asking about cell performance, and the Quality team watching process control (Cpk, control charts, defects, lot traceability).

研发工程师关注电芯性能;质量团队关注过程控制(Cpk、控制图、缺陷、批次追溯)。

DESIGN PRINCIPLE

The numbers are always computed by code, and the model only narrates them. That keeps the answers auditable — you can trace any figure back to measured data.

所有数字都由代码计算,模型只负责叙述。因此每一个数字都可以追溯回原始测量数据。

How we validate验证方法

EVERY MODEL SHIPS WITH ITS BENCHMARK

Model versus measured discharge voltage at 0.5C, 1C and 2C for an NMC811 21700 cell, with residuals; RMSE 9.8, 12.4 and 18.7 mV.
Held-out discharge data, NMC811 | Gr-SiOx 21700 (Case 01). The model never saw these curves during calibration. Error is largest in the last 5 % of discharge at 2C, where the validity window ends. 留出放电数据,NMC811 | Gr-SiOx 21700(案例 01)。模型在标定时从未见过这些曲线。误差集中在 2C 放电末端最后 5 % 容量——这也是适用边界的终点。
STEP 01

Parameterisation

Parameters come from your own measurements, or from a documented literature source with its uncertainty stated.

参数化

参数来自客户自有测量,或来自有出处的文献值,并明确标注不确定度。

STEP 02

Held-out validation

Calibration and validation datasets are kept separate. We report error against data the model never saw.

留出验证

标定与验证数据集严格分开,误差指标基于模型未见过的数据。

STEP 03

Stated limits of validity

Each model comes with the C-rate, temperature and SoC window in which it was validated — and where it should not be trusted.

明确适用边界

每个模型都给出经过验证的倍率、温度与 SoC 区间,以及不应外推的范围。

STEP 04

Handover you can run

Deliverables include the model, the scripts, and a report your team can reproduce line by line.

可复现的交付

交付内容包括模型、脚本与报告,客户团队可以逐步复现结果。
