This project implements a script to calculate the state-of-charge of a simulated battery as specified in the Wärtsilä Battery Take Home Question PDF.
The solution is implemented as a ts-node script supported by a few additional modules.
The instructions do specify "single-file code" and an equivalent function signature:
calculateSoc(hour: float, power: int, currentSoc: float) -> float.
In keeping with the instruction to "Add any comments and structure that you would normally add to a production code-base" I've implemented a more modular, object-oriented approach.
If favorable evaluation is contingent on following the letter of the law, I'm willing to re-implement along those lines :)
The script run-power.ts takes the path to an input file as its sole argument, e.g.
./src/run-power.ts ./power-over-time.csv
There's a simple Jest test to verify that the code generates the expected outputs when configured according to the PDF. Invoke via:
npm test
