Coil cost optimization balances copper/litz weight, ferrite tile area, potting volume, and process steps (hand vs automated winding). Saving on inner turns that contribute little to k but add disproportionate loss is smarter than uniform turn reduction.
Fleet programs feel cost through yield and field returns — cheapest coil that fails Rac screening is expensive at scale.
01Cost levers
- Right-size OD to alignment spec, not oversized 'just because'.
- Standard ferrite tile sizes vs custom cuts.
- PCB auxiliary coils vs all-litz where power allows.
- Modular design reducing unique SKUs across vehicle variants.
02Guards
Any cost reduction must re-run thermal and misalignment power maps. Second-source litz requires Rac equivalence, not only gauge match. Do not drop Hi-Pot or sampling without reliability review.
03Total cost
- Include pad downtime cost in serviceability design.
- Tooling amortization for ferrite vs NRE on custom bobbins.
- Logistics weight of ferrite-heavy pads for international installs.
