The Charge Sheet
A

About

I'm Aatish Patel. I build physical products and the businesses around them, and I've spent the last several years doing that in EV charging.

The Charge Sheet exists because most of what I know about charging, I learned by getting it wrong first, or by watching someone else do it. The information is out there, but it's scattered across vendor brochures, utility tariff books and forum arguments, and most of it is trying to sell you something. This isn't. It's free, it's open source, and it will stay that way.

Wherever I could, the numbers come from real sites and real data. Where I had to assume something, the tools say so, and you can change it. If you think something here is wrong, you're probably right about something, and I'd like to hear it.

How I got here

  1. Fellowes MobileSupply chain engineer on injection-molded phone cases for Walmart, AT&T and Verizon. Where I learned that a product is mostly its supply chain.
  2. Desktop MetalMetal powders, then technical program manager across printer and product lines.
  3. FormlabsBuilt the Fuse powder product line from zero, set up its supply chain in Germany, and shipped the first SKUs.
  4. XCharge North AmericaFounded it in February 2021 and ran it for the better part of six years, across product, sales, marketing, HR, finance and logistics. A polite way of saying I've done most jobs in a charging company, including a few nobody wanted.
  5. XCharge (Nasdaq: XCH)Chief operating officer. Took the company public in September 2024 and ran the IPO roadshows myself.

I studied mechanical engineering at NYU and management at Harvard Extension School. I also grew up around my family's hotel business, which taught me early that a charger is a guest amenity before it's a business.
