Electric Vehicle Inverter Specification Example for Scooter Fleets: Long Life Version
Electric Vehicle Inverter Specification Example for Scooter Fleets: Long Life Version
This is a worked specification for electric vehicle inverter in a long life 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 long life version version exists because the duty cycle on scooter fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

Where this example applies
Programmes that run long life version most often specify this build for scooter fleets. Related applications include aftermarket retail, three-wheelers, emergency vehicles, assembly programmes, export programmes.
Checks before packing

- AQL 4.0 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
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
