Battery Cost Is the Central Variable in BEV Competitiveness
The biggest variable shaping electric-vehicle cost competitiveness is the battery. Battery pack prices push down the total cost of ownership (TCO) boundary against internal-combustion-engine (ICE) vehicles and determine which vehicle classes and regions make BEVs economically rational. The downward trend in prices continues. According to the IEA, battery prices in China fell by about 30% in 2024. The issue is that this decline does not work uniformly across the world.
Three Structural Factors Driving the Price Decline
Battery prices have continued to fall even during periods when battery metal prices have not necessarily declined. When raw materials stay elevated but pack prices still fall, the background is not just price movements themselves but structural change. The following is our view of the factors that have pushed prices down.
Cell manufacturing overcapacity
Global additions to cell production capacity have exceeded demand, triggering price competition as suppliers try to secure utilization. Supply-side overcapacity has helped absorb increases in metal costs.
Shift to LFP
Adoption of cobalt- and nickel-free LFP (lithium iron phosphate) has risen. LFP is cheaper than NMC (nickel manganese cobalt), so the shift in mix pulls the overall average down. Adoption is advancing in applications that prioritize low cost over energy density.
Scale effects from stationary storage
Demand growth for stationary storage is lifting scale effects across the cell industry and becoming a source of cost decline alongside transport. The wider the demand base becomes, the easier it is for unit costs to fall.
The Cost Boundary Is Not Uniform Worldwide
This is where the practical trap lies. Treating cost parity as one common global point leads to wrong decisions. The IEA's analysis shows that BEVs already have a price advantage in China, while combustion cars remain cheaper than comparable BEVs in Germany and the United States. Differences in local production costs and battery sourcing structures create this gap. The sharp decline in China's battery prices further widens that advantage.
In other words, the BEV cost boundary shifts by region. In China, BEVs have a price advantage over ICE/HEV across a broad range of vehicle classes. In Europe and the United States, battery costs are higher and the boundary arrives later. The bifurcation in which China and emerging markets move ahead in BEV adoption while the West moves more gradually is also supported by this regional battery-cost gap. China's position as the source of more than 70% of global production and about two-thirds of sales further strengthens its cost leadership.
Why HEV/PHEV Remain Thick in the Mid-Term
Even as battery prices fall, there are reasons HEVs (hybrids) and PHEVs (plug-in hybrids) remain resilient in the mid-term. Charging-infrastructure coverage, cold-weather range performance, and the regional cost boundaries described above all slow a one-way shift to BEVs.
Automakers' HEV line expansions and EV-plan deferrals are often cited as evidence that EVs are unnecessary. More precisely, they should be understood as a mismatch in investment timing. If falling battery prices push BEV TCO below ICE/HEV and fast-charging networks become sufficiently dense, the HEV advantage will shrink. Conversely, until those two conditions are in place, multiple pathways can rationally coexist.
This view is falsifiable. If BEV pack prices fall further in major regions and fast-charging network coverage crosses the threshold, the HEV advantage will shrink sooner than expected. If battery-price declines slow and regional gaps do not narrow, HEV/PHEV thickness will last longer. What should be watched is not the "global average battery price" but "pack prices and charging-network coverage by major destination market."
