Overview

Open Charge Map is a global registry of electric vehicle (EV) charging stations with detailed location and connector information. You need a free API key to access it, which you can request on their website. It is an excellent resource for building EV trip planners or mapping applications.

💡

Beginner Tip

Use the latitude, longitude, and distance parameters together to find nearby chargers. Start with a large distance (e.g., 10 km) to make sure you get results before narrowing down.

Common Errors & Troubleshooting

401 Unauthorized or empty results API key is missing or invalid
✓ Register at openchargemap.org to obtain a free API key and pass it as the key query parameter
Empty results array No charging stations found within the specified radius
✓ Increase the distance parameter or verify that latitude/longitude values are correct
Too many results or slow response maxresults parameter not set, defaulting to a large number
✓ Always include maxresults (e.g., maxresults=20) to limit response size and improve performance
