Wanted PCB board designer

Post by ecat » Jun 26 2019 3:48pm

Hello, I need an electronics engineer or someone who has extensive PCB board experience to design a simple interface board.

The circuit board would acts as an interface between an already developed DIY 18650 lithium powerwall system, and a commercial battery management board.
The applicant would be provided the DIY powerwall board, and components, and the BMS board, and would design a new circuit board that would interface the two. There would be no active circuitry to develop, it is mostly just circuit board layout.

BMS system: https://www.energusps.com/shop/category ... nagement-4

On successful completion of the project, there is a further design project possible for a relay board that would involve circuit design, layout, and testing.
I can pay a reasonable fee for this service on a project completion basis.

What has to be "interfaced?" Just a shutdown signal? A bunch of sense lines? That sounds more like a cable construction project than a PWB.

My idea is that a board would be made up that works with Jehu's system, and the Tiny BMS would sit on top of it like a daughterboard, with the connections made with headers or ribbon cables.
