Honda has converted a plant built for electric vehicle production into a facility making batteries for data centers, according to a report from Mezha.

The repurposing marks a shift in how one major OEM uses manufacturing capacity as EV demand undershoots earlier forecasts. Honda built the plant to supply batteries for its electrification programs. Now the same site will feed stationary storage — a market growing on the back of data center construction rather than vehicle sales.

Details of the conversion — the plant's nameplate capacity, the investment in retooling, workforce numbers, and the start date for battery output — were not disclosed in the report. Honda has not specified how much of the site's original EV battery capacity transfers to data center production, nor which data center operators or energy storage partners will take the output.

The move fits a broader pattern. Automakers across North America, Europe and Japan have slowed or restructured EV battery investments over the past two years as adoption rates came in below the projections that underpinned capacity announcements. Several OEMs and battery makers have delayed plant openings, cut shifts, or sought alternative outlets for battery output. Stationary storage — grid-scale and data center batteries — has emerged as the most credible adjacent market, since it uses similar cell chemistry and manufacturing processes without depending on vehicle demand.

For Honda specifically, the conversion signals that the company views data center power demand as a more reliable near-term growth story than its own EV volume projections. Hyperscale operators are contracting battery supply to manage power costs and grid constraints, and suppliers with existing cell manufacturing capacity can serve that market with lower retooling cost than greenfield entrants face.

What to watch: confirmation from Honda on the converted plant's location and output capacity, the first shipment date for data center batteries, and whether the company frames this as a temporary flexibility measure or a permanent line reassignment. Any change in Honda's stated EV battery capacity plans across its broader plant network would clarify whether this is a one-site pivot or the start of a wider reallocation.
