How is Battery Pack Prices constructed?
Published by Deepstory Research as the methodology attached to Battery Pack Prices. Scope and source attribution are bounded by that Evidence Brief.
Procedure and scope
Prices are BloombergNEF’s annual volume-weighted average PACK price (not cell price), covering both EV and stationary-storage demand. Pack prices sit above cell prices by the cost of the module, housing, thermal management and BMS — comparing a pack figure to a cell figure is a common error and would overstate the decline. CAVEAT: only 2023 and 2025 are seeded on the trend chart. BNEF publishes a full annual series, but the two releases cited here give levels for those two years only; 2024 is expressible only as "8% above 2025", which is a derivation rather than a published value, so it is omitted. The regional bars for North America and Europe ARE derived — BNEF publishes them as premia (+44% and +56%) over the published China level of $84/kWh. The arithmetic is stated in each value_basis so the derivation is visible rather than hidden. Re-verified 2026-08-10.
Known failure modes and limits
- Cell-level prices or chemistry-specific breakdowns.
- Whether quoted regional prices reflect tariffs or subsidies.
- Forward prices.
