Ford的Ted J. Miller,先生写的很全，这大概就是OEM厂家在电池厂家的配合之下，仍旧要熬那么长段时间才能有所成就的原因了。

Automotive Cell Designs

这是电池厂家作的事情……

Durability: material selection and validation,demonstrated long life packaging,manufacturing process and controls

Abuse tolerance: passive safety features

Power:internal resistance minimization (component and weld stack up analysis)

Terminals: proper sealing is critical,sufficient landed area (current carrying without excessive heating),flexibility for bolted and welded connections

Thermal:validated model of heat generation and transfer

Low cost: uniformity，manufacturability，low scrap rate

New Technology Requirements

新技术导入需要做的工作

Data

– Performance (vs. T, SOC, and life)

– Life (cycle and calendar)

– Cost (detailed BOM and model)

– Abuse tolerance (subsystem testing)

Design information

– Packaging (durability)

– Electrical (high current appropriate)

– Thermal (heat transfer model)

Models

– MATLAB-based performance and life model

– Thermal (included in MATLAB model if possible)

– Cost (materials, depreciation, labor, overhead, assumptions)

Credible manufacturing plan

– Plant investment, timing, and production design qualification

– Production materials and equipment suppliers and support

– R D plan for performance improvement and cost reduction

Fundamental analysis

– Performance degradation identification and validation

这里将对单体电池的模型建立单独拿出来，而且这还有个从个体到整合之后的模型转换问题。

Battery Modeling Requirements

Performance Model

– Cell-level equivalent circuit model in MATLAB which provides:

1. voltage and current response based on power demand or input,

2. response over the full operating temperature range

3. thermal response during simulated usage

4. degradation behavior as a function of simulated usage/life

Electrochemical Model

– determine electrode-level behavior and performance limitations over the full operating range (temperature, pulse current and time,ΔSOC, and cell life)

– Verification testing is required to validate the model

Life Model

– A cell life (cycle and calendar) model must be developed in order to determine to effects of usage and stand time

– The life model must consider the fundamental cell performance deterioration mechanism

– Verification testing lab analysis is required to validate the model

而最为头疼的安全问题，从FMEA（FTA / FMEA Safety Analysis Model for Lithium-ion Batteries）到Abuse以UL的表格
