Sebang Lithium Battery simultaneously won orders for Hyundai Motor's new hybrid (HEV) battery packs and LG Energy Solution's new ESS (JF2) battery packs, together worth more than KRW 3 trillion (reported 2026-09-07). This article quantifies, under an assumed scenario, how the Cell Inbound Interface and Cell-ID Traceability load differ when a pack systems company that sources cells externally receives two heterogeneous product lines — automotive and grid-scale power — within a single organization. The conclusion is that the traceability system's load scales with cell count, not GWh. In the assumed scenario, the HEV pack, at 0.45 GWh/year, is only 1/17.8 the scale of the ESS module (8 GWh/year), yet its…
