真实负载循环,逐点直算
损耗 · 结温 · 寿命一目了然 Real duty cycles, point by point
loss, Tj & lifetime at a glance

导入真实工况序列(电流 / 电压 / 功率随时间变化),系统逐工况点自动算损耗、结温与裕度,并给出热循环与寿命评估建议 —— 把靠经验的「拍脑袋」变成基于真实工况的量化分析,覆盖全工况、不漏点。 Import a real mission profile (current / voltage / power over time) and the system computes loss, Tj and margin for every operating point, with thermal-cycling and lifetime hints — turning intuition into data-driven analysis, with full coverage and nothing missed.

手工跑工况,卡在这三步Manual mission-profile work gets stuck here

01 / 04

逐点手算,费时易错Point-by-point by hand

几十个工况点逐一拉曲线、查表、算损耗,过程繁琐,极易漏点或抄错,复核耗时。Dozens of points, each curve-by-curve and table-by-table — tedious, easy to miss, painful to review.

热循环寿命靠经验Lifetime guesswork

结温摆幅与寿命评估长期依赖资深经验,缺逐工况真实数据支撑,风险难量化。ΔTj swing and lifetime rely on senior intuition, without per-point data to quantify the risk.

结果碎片化难复用Scattered, hard to reuse

手算结果散落在表格、脚本里,难以系统复用到设计评审、报告或下一步计算。Manual results live in scattered sheets and scripts — hard to feed into reviews, reports or the next step.

怎么分析How it works

三步,从工况序列到逐点结论From a profile to per-point conclusions — in three steps

本地组装与校验参数,核心计算调用专用计算引擎,AI 层做结果解读与建议。Parameters are assembled and validated locally; core computation runs on a dedicated engine; the AI layer explains and advises.

常见问题FAQ

关于负载循环分析About load cycle analysis

04 / 04
负载循环分析支持哪些输入?What inputs does it support?+
支持常见表格 / 时间序列格式导入,序列至少包含时间与电流、电压或功率列,可来自实车、实测或仿真。系统会校验单位与完整性,缺失或异常点会提示修正,确保分析建立在准确数据之上。具体支持的格式以演示为准。Common tabular / time-series imports are supported; the sequence needs time plus current, voltage or power, from vehicle, lab or simulation. The system validates units and completeness and flags gaps. Exact formats are confirmed in the demo.
工况点很多,分析速度如何?How does it handle many operating points?+
针对多工况点批量分析做了优化:参数组装与校验在本地完成,核心计算提交专用引擎,即使上百个工况点也能批量跑完。具体性能指标正在用真实工况校准中,确认后会公布。It's built for batch analysis: assembly and validation run locally while the core computation goes to a dedicated engine, so even hundreds of points run in batch. Exact performance figures are being calibrated and will be published once confirmed.
能体现不同散热条件的影响吗?Can it reflect different cooling conditions?+
可以。配置分析时支持设定散热相关参数,系统在逐点计算结温时会结合这些热约束,给出每点的结温与摆幅 ΔTj,使热循环评估更贴近真实系统。具体可设参数范围以界面演示为准。Yes. You can set cooling-related parameters; the system then computes Tj and ΔTj per point under those constraints, bringing the thermal-cycling assessment closer to your real system. The exact parameter scope is shown in the demo.
怎么查看每个工况点的详细结果?How do I review per-point results?+
分析完成后,结果区展示逐点数据表与趋势曲线,包括每点的导通损耗、开关损耗、结温、结温裕度与谐波分量;展开任意点可看该点的器件应力说明与设计建议,帮助快速定位高风险工况。After analysis you get a per-point table and trend plots — conduction loss, switching loss, Tj, Tj margin and harmonics per point. Expand any point for device-stress notes and design hints to zero in on high-risk conditions.
结果能直接进设计评审或技术报告吗?Can results feed reviews or reports?+
可以。负载循环分析结果可衔接 PowerPilot 的设计计算与报告生成,一键导出含工况统计、损耗分布、结温曲线与寿命评估结论的结构化技术报告,内容可追溯,满足内部评审与归档。Yes. Results connect to PowerPilot's design calculation and report generation — one click exports a structured report with duty-cycle stats, loss distribution, Tj curves and lifetime conclusions, traceable and ready for review and archiving.
