Electric Vehicle Inverter Specification Example for Three-Wheelers: Lightweight Version
Electric Vehicle Inverter Specification Example for Three-Wheelers: Lightweight Version
This is a worked specification for electric vehicle inverter in a lightweight version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The lightweight version version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Semi-Metallic Compound, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- ultrasonic cleaning
- cold forging
- laser cutting
- rubber vulcanisation
- sintering
- die casting
Where this example applies
Programmes that run lightweight version most often specify this build for three-wheelers. Related applications include assembly programmes, city buses, trailer axles, fleet maintenance, three-wheelers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO 9001-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
