This is a very simple design of a electric battery connector that covers the need of charging an Amparo 12Ah KTM e-bike. Given that I could not find a commercially available connector I capture the mechanical dimensions and electrical requirements to match my battery charger rating.
The design is compose of the next parts:
- Pins to match the battery connector (pure nickel 1.5mm).
- PCB that capture the position of the pins and facilitate electrical connections.
- Two part case that provides rigidity, pin short circuit protection and alignment aids.
The case and pins have been designed using Fusion 360 and because of that it can be shared but not edited. Exported models will be available under the ''Models'' folder
The PCB has been designed with KiCAD 7.0 which made everything very easy.
Thanks to the Hawthorn Community Connected Hacker Space (CCHS) for ideas, assistance cutting the pins and in general being a bunch of very helpful and skilled people. Thanks for the bicycle and the rework of the battery to another bunch of helpful people: The Recycling Bicycle Shed in the Ceres Environmental Park.
Also thanks PCBWay for sponsoring the CCHS, providing members with free PCBs. Yuhuu!.
