Technology
Four layers. One integration. Zero guesswork.
VideoEV is a CSMS-agnostic middleware that ingests EV charging session events, resolves anonymous hardware identifiers to verified vehicle profiles, runs a real-time ad auction, and closes the attribution loop via Amazon Marketing Cloud — without ever storing a raw vehicle identifier.
End-to-End Stack
From charger plug-in to purchase attribution
CSMS Event
OCPP 1.6 · 2.0.1Charger fires an OCPP session event. VideoEV ingests it in real time across Driivz, AMPECO, ChargeLab, and EV Connect — normalized to a single payload regardless of source.
Identity Resolution
ISO 15118 · DeterministicThe EVCCID — an encrypted hardware identifier — is matched against the Vehicle Identity Graph. No VIN transmitted. One confirmed match returns Make, Model, Trim, and MSRP proxy.
Ad Auction
Real-time · SSP bid requestVehicle profile passes to the SSP as a targeting signal before the first ad slot fills. Buyers bid on VIN-level segments — Tesla owners, Porsche drivers, luxury EV buyers — in real time.
Attribution
Amazon AMC · Closed-loopImpressions are matched to downstream purchase events via Amazon Marketing Cloud. Closed-loop attribution without a pixel — from charging session to Amazon cart.
Universal Compatibility
One integration. Every network.
Every CSMS exposes a different API surface. VideoEV abstracts that complexity into a single normalized event stream — so your ad infrastructure never breaks when a network upgrades their platform.
Real-time OCPP 1.6 / 2.0.1 event streams via native webhook bridge.
Session lifecycle events normalized from REST polling + push webhooks.
Cloud CSMS session data surfaced via OCPI-compatible event API.
Network session data ingested via direct certified integration.
Vehicle Identity Graph
The charger doesn't know what car just plugged in. We do.
Under ISO 15118, EV chargers never receive Make, Model, or VIN — only an encrypted hardware identifier called an EVCCID. VideoEV built the resolution layer that deterministically matches it to a verified vehicle profile before the first ad slot fills.
No probabilistic modelling. No behavioural inference. A confirmed match attaches Make, Model, Trim, Model Year, and MSRP proxy — passed to the SSP in the bid request.

Zero PII. Full attribution.
Raw vehicle identifiers are hashed at the point of ingestion. The original value is never written to disk, never logged, and never transmitted downstream. Attribution precision is preserved through the hashed token — without any PII leaving the origin system.
API Reference
The universal webhook schema
Every CSMS speaks a different dialect. VideoEV normalizes them into a single consistent payload — one integration for every network.

Ad-Tech Architecture
Built to spec. Programmatic-ready.
VideoEV supports 2026 programmatic standards. Your trading desk can activate a campaign without custom integration work.
Automated buying and selling of screen inventory — no manual IO required. VideoEV's kiosk and in-car surfaces are available as pDOOH inventory, discoverable through any compatible DSP.
Where brands and agencies buy ads programmatically. VideoEV inventory is directly accessible via Amazon DSP (primary, enables AMC attribution) and The Trade Desk via OpenRTB 2.6.
VideoEV operates its own SSP layer, exposing charging-session inventory to DSPs. Sellers can set floor prices per station network, MSRP tier, or station environment.
Protocol Support
Full Pod Bidding support — multiple advertisers compete for individual 30-second slots within a single 20-minute charging session. Each pod can hold up to 10 ad units, enabling layered campaigns across a single impression window.
Video ad serving across all three surfaces. Supports interactive overlays, VPAID-compatible measurement, third-party verification tags, and proof-of-play reporting.
DSP Compatibility
Direct integration — enables AMC closed-loop attribution
Via DOOH extension — full programmatic access
Native DOOH DSP with location intelligence
Additional DSPs and Direct IO available on request

Enterprise Integrations
Built on the standards your stack already trusts.
No proprietary lock-in. Every layer of VideoEV speaks an open standard — so your DSP, ad server, and attribution platform plug straight in.
EVCCID, SoC, and session duration — direct from the charger. No API middlemen. The EVCCID feeds our Vehicle Identity Graph.
Standard OpenRTB 2.6 bid stream. Any DSP can access our inventory without custom integrations.
VAST 4.2 compliant. Drop in any video creative from any ad server. Full measurement support.
Close the loop: impression to Amazon purchase. The only OOH medium with confirmed retail attribution.
Listed on Vistar Media's DOOH exchange. Buyers already active on Vistar can reach VMN inventory instantly.
First-party Amazon audience sync. Retarget existing Amazon shoppers by vehicle segment and location.
