HSSMI worked with Ford to develop a repurposing strategy, evaluating the suitability of repurposing the currently installed ICE Bill of Process (BOP) machining and assembly production lines and facilities to produce equivalent EV components.
The methodology followed to develop this repurposing strategy was:
1. Analysis of an ICE BOP.
Having determined the engine plant to be assessed, the HSSMI technical team created a thorough analysis of the ICE BOP gathering key information in an Equipment Repurposing Comparator (ERC) sheet. The information captured included: workplace detail and layout, component complexity information, key facility requirements, error proofing and an equipment list.
2. Analysis of an EV BOP.
The maturity of the EV BOP was not at the same level as the ICE BOP. Therefore, CAD models, bill of sequence (BOS) and benchmarking information was used to complete the EV comparator sheets.
3. Comparison of ICE BOP to EV BOP.
The ERC sheets enabled comparison of the machining and assembly processes between the various ICE and EV components and final assemblies, making it possible to evaluate the re-use potential of ICE equipment with respect to EV production against 3 categories:
- Re-use minimal re-tool required.
- Re-use further work required.
- ICE specific major re-tool.
