Standardized Protocol for Real-Time APIs as Required by Title 23 CFR 680.116(c)

Summary

The U.S. Department of Energy and Department of Transportation have published a standardized protocol for real-time APIs for EV charging stations, as required by 23 CFR 680.116(c). This protocol, version 1.0 expected in September 2024, mandates that static data fields update daily, while dynamic data such as port status and pricing must update within 15 seconds. The API should achieve an average response time under 1,000 milliseconds and maintain 99.5% uptime (maximum 3.6 hours downtime per month). It specifies a rate limit of 1,000 requests per hour for verified users and aims to support 10,000 registered API users with 1,500 simultaneous requests. Geographic coordinates require 6-decimal precision, and charging levels are defined across AC Level 1 (120V), AC Level 2 (208-240V), and DC fast (400-1000V).
