High-voltage two-wheel EV, signed for series production.

Tomco ran functional safety and battery-system assurance for a leading electric motorcycle OEM — ISO 26262 item definition through UNECE R136 type approval, with the high-voltage battery case as one continuous evidence chain.

Program narrative

How the engagement ran.

The client is a leading electric motorcycle OEM moving from a hand-built first generation into a high-volume platform shared across multiple model lines. The new platform required a defensible ISO 26262 case for the powertrain, a UNECE R136 (L-category EV) submission for type approval, and an ISO 6469 / SAE J2929 evidence package for the high-voltage battery system.

Tomco embedded as the safety partner from item definition through SOP. AFSPs co-signed the hazard analysis, the ASIL decomposition across motor controller, BMS, and ride-by-wire, and the full V&V evidence package. Agents kept the trace from hazard → safety goal → requirement → test current as the hardware spun through three silicon revisions.

Type approval came back clean and the platform shipped on schedule. The same case structure now absorbs each new model variant without re-opening the standards mapping — a pattern the client has standardised on for every future EV program.
