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

大概就知道需要干的事情，真的是很多……

   我们走的快，不是别人不会走，只是我们略过了其实不能略过的路，而且有些地方还尽搞些事情来自我安慰，真正从设计、生产和测试等角度来看，应该做的事情其实是补功课。
