EV passport

Your electric's passport: the multi-agency service record that travels with every EV you sell.

The battery is 40-60% of an EV's value.

Every shop scan adds to a verifiable, signed, living history.

When the EV is resold, the EV passport travels with the VIN — protecting the asset's value.

Your electric's passport

A signed history that travels with the VIN

Not an isolated report. A continuous record, co-signed by certified workshops, transferred to the next owner when you sell.

You import the EV. SOHpro joins the VIN from day one.

The first scan is bound to your brand as the Importer. Not metadata — a permanent seal that lives with the VIN.

02 · Importer Seal

Your seal #1: "Imported by your dealership" — permanent, with your brand for the EV's entire life.

This seal is anchored to the VIN. Every future owner, every buyer inspecting the EV before purchase, every other shop that touches it — they all see it first.

03 · Happy customer

Your customer receives their EV with scientific proof of battery health.

An EV passport in their pocket from delivery. Score, history, shop signature. No papers to lose.

04 · Service visits

Every visit, every shop, gets recorded.

Your customers have a reason to come back — each visit enriches their EV passport. And partner-shop seals add up too, without erasing your Importer seal.

05 · Real-time

Your customer sees the maintenance progress as it happens.

No status pings, no phone calls. When the tech marks the visit "in progress", your customer's phone reflects it. When it ends, the report appears signed in their EV passport.

Direct health indicators

Five readings that can be evaluated from a single scan. Each one is compared against healthy ranges established in the literature.

  • Energy returned while driving (round-trip efficiency)
    93.4 %
    Healthy: ≥ 95%
  • Charge the pack retains (coulombic efficiency)
    99.7 %
    Healthy: ≥ 98%
  • How evenly matched your cells are (σ(V))
    1.40 mV
    Healthy: ≤ 3 mV in NMC at mid-SOC
  • Electrical safety margin (HV insulation)
    9.4 ×
    Healthy: ≥ 2× over the ISO 6469-3 floor
  • Resting-voltage consistency (OCV vs SOC)
    8 mV
    Healthy: ≤ 30 mV deviation
06 · Science + AI

Every report: chemistry-aware, banded, auditable.

Five physical indicators crossed against the pack's real chemistry — LFP, NMC, NCA all have different thresholds and we respect them. Bands verified against public literature, code open to audit.

07 · Resale

The day comes. The EV is sold.

The EV passport travels with the car to the next owner. The new buyer inspects the full history before closing — and sees, at the very top, "Imported by your dealership — since 2024". Your brand stays. For life.
