Electric Vehicle Inverter Specification Example for Delivery Vans: Vented Design
Electric Vehicle Inverter Specification Example for Delivery Vans: Vented Design
This is a worked specification for electric vehicle inverter in a vented design 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 vented design version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.
Example specification
| Item | Electric Vehicle Inverter |
|---|---|
| Application | Delivery Vans |
| Version | Vented Design |
| Base material | Magnesium Alloy |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | zinc plated |
| MOQ | 3,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | ISO/TS 16949 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Magnesium Alloy, 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
- cold forging
- shot blasting
- gravity casting
- CNC machining
- ultrasonic cleaning
- sintering
Where this example applies
Programmes that run vented design most often specify this build for delivery vans. Related applications include construction equipment, export programmes, assembly programmes, light trucks, aftermarket retail.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO/TS 16949-compliant build instead of a fresh interpretation.
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO/TS 16949 documentation is issued with the shipment when your market requires it.
