Capital as a factor of production includes not only money (although in this case Caroline is asking for money), but is also includes equipment, physical tools, machinery, production facilities, offices, etc. Capital can include any physical asset that a company uses to increase labor productivity.
Based on the given paragraph, I would have to say that Caroline is asking for a capital since these are the materials she needs to make the first 100 chargers. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
