The Chosen Way to Solving EV and Data Centre Energy Management Challenges

Worapoj Chosen is the Founder and CEO of Chosen Digital Co., a multiple-award winning start up company from Thailand in the Electric Vehicles (EV) energy aggregation and management space. He spoke with the CarbonWire and AsiaBizToday team at SusHi Tech Tokyo 2026 on his start-up’s journey so far and plans for the immediate future.

Explain the business of Chosen Digital and the problem it is trying to solve.

Thailand is committed to move to 100% Electric Vehicles by 2035; however, the real challenge is the necessary infrastructure to support the electricity demands from EV charging. Similarly, the demand for electricity from data centres is surging and we are not geared up for this. Our current infrastructure is not designed for the increased load from transition to EVs or boom in data centres. In Thailand alone, there are more than 500,000 transformers that need to be replaced to accommodate the growing demand. If we don’t do anything soon, we will face a crisis

Our goal is to be the enabler of solutions to achieve “net zero” in Thailand, with special focus on the EV energy management space by being an ‘energy aggregator’

How exactly are you solving the problem?

EV charging has had issues and limitations pertaining to brand, protocol and country/ region specific technology – for example, American, European and Chinese. It has been quite fragmented, which means that managing the EV charging infrastructure in a single system is not easy. What we offer is ‘neutral’ and not tied by these limitations

We are able to help manage and reduce up to 75 percent of the load, which can result in a huge cost saving. Secondly, we can also combine the energy from multiple sources such as from EV batteries, solar and so on and bring back power to the grid for those who need it. So, we also act like a Virtual Power Plant (VPP)

How long have you been operating in the EV energy management space?

We have been developing our system over the last seven years as part of a different IT company that specialised in industrial inspection. We spun off this unit about 4 years ago to focus on the energy problem, as the pain points were obvious and we felt we had a good solution.

What kind of traction have you gotten so far?

Thailand is obviously our major market, but increasingly we are getting traction and inquiries from other Asian countries as well. Besides the provincial electricity authority of Thailand, we have executed several proof-of-concept for other government utility agencies as well. We are also talking to some large Malaysian companies. We are scheduled to speak with the Ministry of Economy, Trade and Industry (METI), Japan in early May.

What sort of revenues are you generating currently?

We consider ourselves quite an early-stage deep-tech company. Most of our work currently is in executing proof-of-concept in the Business-to-Government (B2G) space, which we expect to be a huge driver for us as governments are the ones most interested in addressing energy infrastructure challenges.

Of course, governments take time and hence we are targeting the B2B sector – hotels and apartment complexes, for example. We do have to cater to some custom requirements of these customers

We operate on a “Energy as a Service” subscription model, similar to Software-as-a-Service (SaaS) model. We are generating annual revenues of about US$ 500,000 from the business-to-business (B2B) segment with over 150 buildings on our platform already and this is growing. Our goal is to be the leader in Asia in this field within the next three years.

What are your expectations from participating in SusHi Tech Tokyo?

This is the first time we are participating at SusHi Tech Tokyo as part of the ASEAN SPARKS (Shaping Pioneers to Accelerate Renewable and Key Climate Tech Solutions across ASEAN) selection of companies. We are selected and slated to participate in several pitch competitions during our time here.

Besides, we are keen to check out the state of relevant technology here, and meet smart people to understand how they think. It is an opportunity to showcase our technology and offering and gather valuable feedback. Hopefully, we will find some good partners, too.
