TeraWatt Technology

TeraWatt Technology Inc. is a next-generation lithium-ion battery company founded in 2020 by Ken Ogata (CEO) and Yifan Tang, headquartered in California with an R&D center in Santa Clara and operations in Japan, including its first mass-production facility in Shizuoka. The company develops, manufactures and commercializes lithium-ion cells engineered for ultra-high energy density, high power output, improved safety and competitive cost, aimed at electric vehicles, drones, eVTOL aircraft and grid-scale energy-storage systems. It closed a Series C round with investors including Khosla Ventures, Temasek, JIC Venture Growth Investments, JBIC, JERA and ITOCHU Technology Ventures. TeraWatt Technology is a hardware manufacturer: it publishes no public API, developer portal, machine-readable contract or SDK, which was verified by probing its only public host rather than assumed.

TeraWatt Technology is profiled on the APIs.io network. Tagged areas include Company, Batteries, Energy Storage, Lithium-Ion, and Electric Vehicles.

TeraWatt Technology’s developer surface includes support and 4 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/terawatt-technology: open an issue to ask a question, or submit a pull request to add artifacts.
