PlugSeed optimises your electric fleet charging at the best trading moments and — where market rules allow — sells unused battery energy back to the grid, cutting energy costs and creating new recurring revenue, without compromising vehicle readiness.
PlugSeed hardware moves power between the grid, on-site solar, the building, and the fleet — in whichever direction makes economic and operational sense. The animation below is an illustrative simulation.
Grid power charges the fleet during low-tariff hours.
A bidirectional DC charging hardware family in development, spanning 30kW to 1000kW and designed to charge and discharge through the same connector.
Forecasts fleet demand, tariffs, and solar generation to schedule charge and discharge cycles automatically.
Designed around the standards for vehicle and charge point communication — plug-and-charge, bidirectional power transfer, and interoperability across brands.
Shifts and shaves site load automatically to help manage demand charges and reduce strain on local infrastructure.
Prioritises on-site solar and supports DC microgrid configurations for corporate and industrial sites.
API-first design that scales from a single site to a multi-site fleet without re-platforming.
Our MVP hardware has already been tested on real vehicles — not simulations — across seven major EV brands, confirming compatibility well beyond a single reference vehicle.
The field-test rig shown above validates charging compatibility; this render shows the planned production enclosure design.
Regulation, fleet electrification speed, and a gap in the market are converging at the same moment.
Under the AFIR delegated act as currently adopted, newly installed or renovated public charge points — and new private Mode 3/4 points — must support ISO 15118-20 from 1 January 2027. It is the standard that enables Plug & Charge and bidirectional energy transfer.
Commercial fleets are electrifying faster than grid connections and depot charging can keep up, and peak-power tariffs make unmanaged charging expensive.
We see a gap for modular, small-series bidirectional DC charging combined with AI fleet energy management, built for SME fleet depots.
Market figures: Renub Research (2025), Europe Electric Vehicle Charging Infrastructure Market 2025–2033 (USD 9.22B in 2024 to USD 64.34B in 2033). Regulation: Commission Delegated Regulation (EU) 2025/656 amending AFIR, Regulation (EU) 2023/1804.
Shifts charging and discharging toward the lowest-cost, lowest-carbon hours available.
Helps sites avoid costly demand spikes by coordinating fleet charging with site load.
Prioritises on-site solar generation for the fleet and building before drawing from the grid.
Intelligent load management can reduce or delay the need for costly site grid connection upgrades.
A wallbox prototype tested on real vehicles across seven brands, with early versions of the companion mobile app and the AI fleet platform.
Target: CE certification of the wallbox and a first small production batch for pilot fleet customers.
Target: pilot-fleet testing, tooling for volume manufacturing, the first AI platform release, and deeper integrations with fleet and back-office systems.
Multi-site fleet aggregation and grid services expansion across European markets.
Plans and dates are targets and may change.

Website means this website, operated by PlugSeed.
Controller means the PlugSeed entity named in the Legal Notice above, which determines the purposes and means of processing personal data collected through this website.
Personal data means any information relating to an identified or identifiable natural person.
Processing means any operation performed on personal data, such as collection, storage, use, or disclosure.
GDPR means Regulation (EU) 2016/679, the General Data Protection Regulation.
Pilot Programme request form — when you submit the form on this website, we collect your full name, work email address, organisation, and any message you provide. This is used solely to respond to your enquiry and assess a potential pilot or business relationship. Legal basis: Art. 6(1)(f) GDPR (our legitimate interest in responding to business enquiries directed to us) or, where applicable, Art. 6(1)(a) (your consent, given by submitting the form).
Private team/investor area — access to the password-gated area of this website is checked entirely in your browser. No password, username, or access attempt is transmitted to or stored by us.
Cookies and tracking — this website does not currently use analytics, advertising, or tracking cookies of any kind. If that changes, this policy will be updated accordingly and, where required, a consent mechanism will be added.
Submitted form data is processed internally by PlugSeed. It is also passed to Resend, a transactional email service, solely to deliver your enquiry to our inbox — Resend acts as our data processor for this purpose. Our website is also hosted via Vercel and GitHub, which may incidentally process data as part of providing hosting infrastructure.
Depending on the hosting region and configuration of the providers named above, data may be processed outside the European Economic Area. [To be confirmed and detailed here once infrastructure and provider data-processing agreements are finalised — e.g. Standard Contractual Clauses or an adequacy decision, as applicable.]
Pilot Programme enquiries are retained for as long as needed to respond to your request and pursue any resulting business relationship, and are then deleted or anonymised, unless a longer retention period is required by law (e.g. for business correspondence or accounting purposes).
You have the right to request access to the personal data we hold about you, to request rectification of inaccurate data, to request erasure ("right to be forgotten"), to request restriction of processing, to object to processing based on legitimate interest, to request data portability, and — where processing is based on consent — to withdraw that consent at any time without affecting the lawfulness of processing carried out before the withdrawal.
You also have the right to lodge a complaint with the data protection supervisory authority competent for the Controller's registered office (e.g. the Austrian Datenschutzbehörde or the Portuguese CNPD, depending on the confirmed operating entity).
For any privacy-related question or to exercise your rights, contact us at management@plugseed.com [or a dedicated privacy contact, once assigned].
Integrity and accountability matter to us regardless of company size. We want anyone — team members, advisors, pilot customers, or suppliers — to feel able to raise a genuine concern about misconduct, safety, or compliance without fear of being disadvantaged for doing so.
The EU Whistleblower Protection Directive (2019/1937) requires companies with 50 or more employees to maintain a formal internal reporting channel, with statutory response deadlines and independent case handling. PlugSeed does not currently meet this threshold, so a formal channel of that kind is not yet a legal requirement for us — we are not claiming to have one, and we think it would be misleading to present heavier infrastructure than we actually operate at this stage.
In the meantime, you can raise a concern directly by emailing management@plugseed.com, marked "Confidential." It will be handled personally and discreetly by the founding team, kept confidential to the extent legally possible, and you will not be disadvantaged for raising a genuine concern in good faith.
As PlugSeed grows, we intend to put a more formal, independent reporting channel in place well ahead of the point where it becomes a legal requirement — this section will be updated when that happens.
Placeholder legal content — to be finalised with legal counsel and the confirmed operating entity before public launch.
