This repository contains the electrical design source used for battery management and monitoring hardware development.

Scope
This repo focuses on:
- Schematic design (
.kicad_sch) - PCB layout (
.kicad_pcb) - KiCad project configuration (
.kicad_pro)
Firmware, web, and mechanical assets are maintained in separate repositories.
Requirements
- KiCad 9.x (recommended)
- Git for version control
Download KiCad: https://www.kicad.org/
Quick Start
- Clone this repository.
- Open
Schaltplan.kicad_proin KiCad. - Work from the project root (do not move files out of this directory).

Schaltplan-backups/ # Automatic KiCad backupsRecommended Workflow
- Create a branch for your change.
- Edit schematic and/or PCB in KiCad.
- Run ERC and DRC before opening a pull request.
- Keep commits focused and easy to review.
For contribution expectations, see CONTRIBUTING.md.
Backups
KiCad can generate backup archives in Schaltplan-backups/.
- Keep backups out of commits unless explicitly needed for recovery/documentation.
- If backup files are included intentionally, mention why in the PR description.

Questions
What parts does the Schaltplan use?
4 parts, built around the IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Schaltplan KiCad files?
From the Akku-Craft/schematics repository on GitHub, at the commit this page was made from: the board is Schaltplan.kicad_pcb and its schematic Schaltplan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schaltplan design in my own project?
Its repository states no licence, so its author keeps all rights: ask Akku-Craft before reusing the design.
