The project

The main purpose of this project is to create a set of build instruction for a DIY NiFe battery.

Any set of instruction will have a number of design parameters. Which will pertain to dimensions, materials and the performance that can be expected. The instructions should show how parameters changes will affect performance.

The construction of prototypes will be done using a 3d printer. This will allow easy scaling and changing of dimensions while at the same time guaranteeing that the unaffected dimensions really stay the same.

Testing will be done to establish relationships between parameter chances and battery performance.

Tests should be repeatable and comparable. I.e. each test must be relatable to previous tests and show what the parameter changes resulted in.

This will result in a lot of testing, and thus an automated testing setup will be highly desirable. At the very least data acquisition must be automated. But it would be advantageous to also automate the charging and discharging processes.

Evaluation of the test results will be an ongoing concern, and will be used to control the direction of the project. While also allowing for some random testing (i.e. changing one or more parameters without a clear purpose just to prevent getting stuck in a dead-end development)

The budget for the project is limited, its a hobby project after all. So especially in the beginning whatever is easily and cheaply available will be used.
