Falling battery costs have been one of the vital constant developments within the electrical car trade for the final decade. Costs dropped from effectively over $1,000 per kilowatt hour in 2010 to $141 per kWh final 12 months. This jump-started one of many greatest shifts within the auto trade within the final century, spurring automakers to plow billions of {dollars} into EVs.
The pattern has floor to a halt this 12 months, with BloombergNEF’s annual lithium-ion battery worth survey exhibiting a 7% improve in common pack costs in 2022 in actual phrases. That is the primary improve within the historical past of the survey.
There are a number of components driving the uptick, however the single most necessary one is rising prices for supplies together with cobalt, nickel and lithium. Whereas costs for nickel and cobalt have come down in current months, and lithium could also be about to show, every of those are nonetheless larger than they’ve been in earlier years. That is pushed by surging battery demand and a lag in how briskly new provide will be introduced on-line.
The typical battery worth would have been even larger if not for the shift to lower-cost lithium iron phosphate (LFP) batteries, which include no nickel or cobalt. LFP batteries have gained important market share within the final three years, with BloombergNEF anticipating them to account for round 40% of worldwide EV gross sales this 12 months. Battery producer margins are also decrease this 12 months, suggesting they’ve absorbed among the rising prices of supplies and elements.

To reach on the common worth, BNEF gathered virtually 200 survey information factors from consumers and sellers of lithium-ion batteries going into passenger EVs, business automobiles, buses and stationary storage purposes. The headline determine is a volume-weighted common, so it hides quite a lot of variation by area and software. The bottom costs recorded have been for electrical buses and business automobiles in China at $131 per kWh. Common pack costs for absolutely electrical passenger automobiles have been $138 per kWh.
On a regional foundation, pack costs have been most cost-effective in China, at $127 per kWh. Packs within the U.S. and Europe have been 24% and 33% larger, respectively.
The large query is what occurs subsequent. BloombergNEF’s vitality storage staff expects costs to stay elevated subsequent 12 months, rising barely in actual phrases over 2022 ranges. Past that, the staff is anticipating costs to start falling once more in 2024 as extra uncooked materials provide comes on-line, provide chain pressures ease, and next-generation battery applied sciences and pack designs begin to make their means into the car combine.
An oft-cited benchmark for when EVs hit worth parity with typical automobiles is $100 per kWh. Based mostly on the up to date estimates for the training charge for batteries from this 12 months’s survey, BNEF predicts that common pack costs ought to fall beneath that threshold by 2026. That is two years later than beforehand anticipated.
It’s price noting, although, that $100 per kWh is a nominal determine that’s been round for over a decade and doesn’t absolutely consider how the price of virtually every little thing has elevated resulting from inflation, notably within the final 18 months. Common new-vehicle transaction costs within the U.S. climbed to greater than $48,000 this 12 months, the very best ever. EVs are pulling up transaction costs a bit, however the price of making a car with an inside combustion engine is also rising.
EV worth parity is best considered a variety than a set threshold. At at the moment’s battery costs, some car segments can already go absolutely electrical cost-effectively with out subsidies. Premium electrical automobiles, for instance, arguably are at worth parity with inside combustion fashions already, as are mini metropolis automobiles in China, the place EV choices begin at simply $5,000. For business automobiles like buses and supply vans, the place complete price of possession issues most, parity can be already right here or very shut relying on the area and utilization sample.
Battery costs do nonetheless must fall additional for extra of the center market to go electrical this decade. That’s undoubtedly nonetheless achievable, however would require far more funding in all areas of the battery provide chain, in addition to in R&D and manufacturing course of enhancements.
