Thailand.

• CONDITIONAL GO: validate a company-controlled Bangkok East–Bang Na–Samut Prakan technical hub, with Chonburi as the first collection/spoke zone.
• Thailand had 412,160 private passenger plug-in cars at 31 March 2026: 326,812 BEVs and 85,348 PHEVs [fti_mar26].
• The fleet is growing quickly but remains young and strongly OEM-controlled.
• Do not approve national franchising or battery-module repair until all gates pass.

Approve a 90-day paid validation programme, a conditional Bang Na–Samut Prakan premises option and six-family platform tests. Defer franchise sales, cell rebuilding, unsupported programming and public charging operation.

DLT-linked March data record 326,812 private passenger BEVs and 85,348 private passenger PHEVs [fti_mar26]. Their sum, 412,160, anchors the service model. Broader passenger-service vehicles and other vehicle classes remain adjacent opportunities.

The all-BEV total includes roughly 90,000 motorcycles plus buses, trucks and three-wheelers. HEVs are non-plug-in. Sales flows are not added to stock. EVS uses only exact private passenger BEV and PHEV stock in its TAM.

Private passenger BEVs increased from a derived 156,164 at end-2024 to 272,828 at end-2025 and 326,812 by March 2026 [fti_2025] [fti_mar26]. The rapid build means warranty and age bands matter more than the headline stock alone.

Thailand registered 55,304 private passenger BEVs and 4,168 PHEVs in Q1 2026 [fti_mar26], after 118,725 BEVs and 18,388 PHEVs during 2025 [fti_2025]. Period flows remain separate from the March stock.

From March 2026, the cautious, base and high scenarios use 12%, 20% and 28% annual growth. These are EVS planning assumptions, not government or industry forecasts.

EVAT-linked data reported 4,643 stations and 13,977 outlets at 31 January 2026, including 8,184 DC CCS2 and 5,382 AC Type 2 outlets [charging26]. PEA and EGAT network figures are subsets, not additions [pea_volta] [egat_elex].

No exact plug-in age/warranty distribution was found. The sum of 2025 and Q1-2026 BEV registrations equals 53.3% of March-2026 BEV stock; this is a directional maturity signal, not an age statistic or proof that those vehicles remain in stock. Deep repair demand must be measured before capex.

DLT trains and authorises inspection personnel separately [dlt_elearning]. EVS should accept remediation referrals without implying statutory inspection authority. No EV-only inspection failure rate is invented.

Core TAM is 412,160 plug-in passenger cars × 55% incidence × THB18,000 = THB4.08bn. Independent-eligible value is THB2.04bn. A 55% Bangkok–Eastern Corridor reach proxy gives THB1.12bn SAM. Base SOM is 3,200 orders × THB28,000 = THB89.6m.

It excludes HEVs, motorcycles, commercial vehicles, charging installation, statutory inspection, body repair, full-pack replacement and franchise fees. Every incidence, spend, eligibility and reach input is labelled as an EVS assumption.

Prioritise used-EV dealers, ride-hailing/rental/delivery fleets, insurers/bodyshops/recovery and corporate/hospitality fleets. Private post-warranty customers will grow but should not carry the pilot alone.

BYD Dolphin led 2025 registrations; JAECOO 5 led Q1 2026, while MG, AION, Deepal, GWM and Tesla remain material [autolife_2025] [autolife_q126]. All advertised functions require VIN/tool/parts validation.

Chinese and global OEMs control warranty/software/parts. B-Quik, FIT Auto, Cockpit and Bosch provide broad independent coverage [bquick] [fitauto] [cockpit] [bosch]. EVS must differentiate through auditable battery/flood evidence, insurer workflow and multi-brand technical governance.

Recommend Bang Na–Samut Prakan for the hub, Chonburi/Pattaya/Laem Chabang for the first spoke, and Rayong as a technical/fleet partner zone. Scores require province stock, rent, labour, flood, insurer and customer-origin validation.

EV3/EV3.5 combines vehicle support with local-production commitments [boi_ev_terms]. Eligibility is scheme- and VIN-specific. The proposed THB24bn replacement programme was still under review in July 2026 [reuters_replacement26] and is excluded from the base case.

BOI can provide tax and non-tax benefits to promoted activities [boi_guide]. EEC and industrial-estate location may help [eec] [ieat]. A routine repair workshop is not assumed to qualify, and no award enters economics.

Thailand’s standard corporate income-tax rate is 20% and VAT is 7% [revenue_tax]. Foreign-controlled service activity may require a Foreign Business Licence or eligible BOI structure [foreign_business] [foreign_company]. Confirm royalties, withholding, transfer pricing and customs.

The OSH Act governs employer safety duties [osh_act]. Use DSD/TISI frameworks as inputs [dsd] [tisi], but do not assume one blanket EV-HV certificate. EVS must authorise each person for defined tasks after training and assessment.

Map local land/building use, BMA/local fire, DIW/factory classification, waste/hazardous substances, electrical/charging, refrigerants, labour, insurance, consumer and PDPA requirements before signing a lease [diw] [factory_act] [bma_fire].

Require isolation, lockout, test-before-touch, insulated tools, PPE, controlled access, rescue equipment, task authorisation and independent audit. Vehicle traction work and fixed/public charging require separate scope determinations.

Thailand’s climate makes wet-vehicle triage material [evat_flood]. No damaged/wet-pack intake or opening before engineered quarantine, monitoring, emergency response, insurer approval and licensed downstream waste handling [diw_ewaste26] [pcd].

Confirm current Thai refrigerant, hazardous-substance, storage, recovery and record duties with DIW/PCD/MNRE. Do not import EU requirements as if directly applicable.

Use clear estimates, diagnostic authorisations, limitations, warranties and complaints [consumer]. Do not imply OEM authorisation. VIN, telemetry, battery and fleet data require PDPA minimisation, security and retention controls [pdpc].

Foreign Business Act, Thai contract/IP/tax and competition analysis are fundamental [foreign_business] [competition]. No franchise sale before one audited Thai operating year, a proven training system and a locally reviewed disclosure/contract pack.

Launch battery-health and flood-history certificates, paid fault isolation, charging/thermal diagnosis, tyres/alignment/brakes/suspension, compliant HVAC, fleet SLAs, collection and mobile triage. Hold module/cell work, unsupported coding and ADAS release.

Use one Bangkok East hub with Thai/English service controls, a VIN/function database, central parts approval and daily HSE governance. Cover Chonburi by collection/mobile triage before adding a spoke.

The illustrative base case generates THB89.6m revenue, 55% gross margin and THB3.28m EBITDA before tax, financing and central allocations. Low case loses THB29.04m; high case earns THB46m. Binding demand and staged capex are mandatory.

Critical risks are brand/dealer instability, OEM access and thermal/flood events. Foreign ownership, household debt, incentive changes and city-level demand are high risks. Multi-brand coverage and paid gates mitigate—not eliminate—them.

Days 0–30: Thai structure/HSE, interviews, province data and tool matrix. Days 31–60: 120 paid jobs, 40 VIN tests and binding site/compliance quotes. Days 61–90: anchor LOIs, HSE audit, conditional lease, lead hire and refreshed board model.

No hub without THB45m credible contracted demand, 120 paid jobs, 90% function success, written approvals, positive validated base economics and a capable team. No franchise before the separate one-year gate.

Obtain province/model-year/warranty stock, paid ticket/cycle-time distributions, OEM function pass rates, parts lead times, site flood/fire requirements, binding insurer/waste quotes and Foreign Business Licence/BOI advice.

DLT/FTI-linked sources anchor stock and flow. EVAT and utilities anchor charging. Thai authorities anchor tax, ownership, labour and environment. Commercial sources map models/competition only. Facts and assumptions remain separate.

Province stock, exact age/warranty bands, EV-only inspection failures, workshop pricing, OEM access, technician supply and insurer terms remain unresolved. Forecasts, TAM/SAM/SOM, regional scores and economics are decision-support assumptions.

The source table records publisher, publication date where available, access date, definition notes and direct URL. Material current pages were freshly checked; URL syntax validation is not a universal reachability claim.

Approve Thailand validation. Authorise a Bang Na–Samut Prakan hub only after every gate passes, use Chonburi as the first collection/spoke zone, and defer national franchising and battery-module repair.
