Open Charge Map Pricing: API Access & Data Costs (2026)

Pricing overview

Open Charge Map offers a pricing model primarily centered around free access for non-commercial purposes and specific commercial scenarios, with options for enterprise-level engagement. The Open Charge Map project maintains a global, community-driven database of electric vehicle (EV) charging stations and provides an API for developers to access this data Open Charge Map developer help. The core philosophy is to support the growth of the EV ecosystem by making charging station information widely available.

For individuals and organizations engaged in non-profit initiatives, academic research, or personal projects, the Open Charge Map API is generally available without direct cost. This free tier also extends to commercial entities whose usage falls within certain defined limits, which are primarily designed to prevent abuse and ensure fair access for all users. These limits typically relate to the volume of API requests per unit of time and the total amount of data transferred.

Commercial operations requiring higher throughput, dedicated support, custom data extracts, or service level agreements (SLAs) are directed to contact Open Charge Map for an enterprise plan. These bespoke plans are tailored to the specific needs of businesses, ensuring that larger-scale integrations can operate reliably and efficiently. The absence of publicly listed enterprise pricing indicates a consultative sales approach, where costs are determined based on the scope, scale, and specific requirements of the commercial user.

The project's sustainability is supported through various means, including donations and the revenue generated from these enterprise agreements. This hybrid model allows Open Charge Map to maintain its foundational free service while also accommodating the needs of professional developers and businesses who rely on its data for commercial products and services.

Plans and tiers

Open Charge Map primarily operates with two broad categories of access: a free tier and enterprise plans. There are no publicly advertised intermediate plans or tiered subscriptions with fixed prices.

Free Access

The free access tier is the primary offering, allowing developers to query the Open Charge Map database for charging station information. This tier is suitable for:

• Personal projects: Individuals building mobile apps, web tools, or research projects for personal use.
• Non-commercial applications: Non-profit organizations, academic institutions, or community initiatives focused on EV adoption without direct revenue generation from the data.
• Limited commercial use: Small-scale commercial ventures that operate within the established rate limits and terms of service. The exact definition of "limited commercial use" and associated rate limits are detailed in the Open Charge Map developer guidelines.

Users under the free access tier are expected to attribute Open Charge Map as the data source and adhere to the project's data license. The API provides a wide range of query parameters, allowing filtering by location, connection type, status, and more. Data updates are continuous, reflecting community contributions and verified submissions.

Enterprise Plans

For commercial entities with significant data consumption needs, stringent uptime requirements, or integration into revenue-generating products, Open Charge Map offers enterprise plans. These plans are customized and require direct contact with the Open Charge Map team. Enterprise plans typically include:

• Higher API rate limits: Increased request volumes and data transfer capacity beyond the free tier.
• Dedicated support: Access to technical assistance for integration and troubleshooting.
• Service Level Agreements (SLAs): Guarantees on API availability and performance, crucial for commercial applications.
• Custom data solutions: Potential for custom data extracts, bulk downloads, or specialized API endpoints.
• Flexible licensing: Commercial terms tailored to specific business models and usage patterns.

The pricing for enterprise plans is determined on a case-by-case basis, reflecting the specific service level, usage volume, and contractual terms agreed upon. This approach allows Open Charge Map to support diverse business needs, from large automotive manufacturers to energy providers and mapping services.

Here's a comparison table outlining the key differences:

Free tier and limits

The free tier of Open Charge Map's API provides access to its global database of EV charging stations without direct monetary cost. This accessibility is fundamental to the project's mission of accelerating EV adoption Open Charge Map homepage. However, to ensure fair usage and prevent system overload, certain limits apply to the free tier.

API Rate Limits

While specific numerical rate limits are not always explicitly published and can be subject to change, the general principle is that usage should be reasonable for non-commercial or limited commercial applications. Excessive requests from a single IP address or API key within a short timeframe may result in temporary blocking or throttling. Developers are advised to implement caching mechanisms and optimize their queries to minimize API calls, thereby staying within reasonable usage parameters.

Data Usage and Attribution

Users of the free tier are expected to adhere to the Open Charge Map data license, which typically requires attribution. This means that applications or services leveraging Open Charge Map data should clearly indicate Open Charge Map as the source of the charging station information. This attribution helps to acknowledge the community effort behind the data collection and maintenance.

Terms of Service

All users, including those on the free tier, must comply with Open Charge Map's overall terms of service. These terms outline acceptable use, data privacy policies, and responsibilities of the user. Serious or repeated violations of these terms, such as attempting to scrape the entire database without authorization or using the data for malicious purposes, can lead to permanent access revocation.

Support

Support for free-tier users is primarily community-driven. Developers can seek help and share insights through forums, developer communities, or the project's public resources. Dedicated, one-on-one technical support is generally reserved for enterprise plan subscribers.

The free tier is designed to be highly functional for a wide range of uses, from developing a personal EV route planner to powering a small-scale, localized charging station finder. Developers are encouraged to review the Open Charge Map developer documentation for the most current information regarding usage policies and best practices.

Real-world cost examples

Given Open Charge Map's pricing model, which features a free tier for non-commercial and limited commercial use, and custom enterprise plans, demonstrating real-world costs involves considering typical usage scenarios for both tiers.

Example 1: Personal EV Route Planning App (Free Tier)

• Scenario: A hobbyist developer creates a mobile application that helps EV owners find charging stations along a planned route. The app performs an average of 100 API calls per user session (e.g., searching for stations, filtering results, getting details). The developer anticipates approximately 1,000 active users per month.
• API Usage: 1,000 users * 100 calls/user = 100,000 API calls per month.
• Cost: $0.00. This usage level is generally well within the free tier's limits for non-commercial applications. The developer would ensure proper attribution to Open Charge Map.
• Considerations: If the app gains significant traction (e.g., hundreds of thousands of users), the developer might need to optimize API calls further or consider contacting Open Charge Map if rate limits become an issue, to discuss potential commercial terms.

Example 2: Regional EV Charging Network Aggregator (Free Tier / Potential Enterprise Transition)

• Scenario: A small startup builds a web portal that aggregates EV charging station data for a specific metropolitan area, combining Open Charge Map data with proprietary information. The portal serves approximately 5,000 daily unique visitors, each generating an average of 50 API calls (e.g., initial map load, detailed station views, search filters).
• API Usage: 5,000 visitors/day * 50 calls/visitor * 30 days/month = 7,500,000 API calls per month.
• Cost: Initially, the startup might attempt to operate within the free tier. However, 7.5 million API calls per month would likely exceed typical "limited commercial use" thresholds and could trigger rate limiting or require a discussion with Open Charge Map. The cost would likely transition to a custom enterprise plan.
• Considerations: If this service generates revenue, Open Charge Map would expect a commercial arrangement. The startup would contact Open Charge Map to negotiate an enterprise plan, with costs dependent on factors like guaranteed uptime, support, and specific API access requirements. This cost could range from hundreds to thousands of dollars per month, depending on the agreed-upon terms and additional services.

Example 3: Automotive Manufacturer's In-Car Navigation (Enterprise Plan)

• Scenario: A major automotive manufacturer integrates Open Charge Map data into its in-car navigation systems across a fleet of 100,000 vehicles globally. Each vehicle generates several hundred API calls per day for live charging station availability, POI lookups, and routing.
• API Usage: 100,000 vehicles * 300 calls/vehicle/day * 30 days/month = 900,000,000 API calls per month (a very high estimate, potentially with significant caching).
• Cost: This scale of usage necessitates a comprehensive enterprise plan. The manufacturer would negotiate a custom contract directly with Open Charge Map. The pricing would likely involve factors such as the number of active vehicles, total API call volume, data synchronization needs, dedicated support, and specific SLA requirements.
• Considerations: The cost would be significant, reflecting the high volume, mission-critical nature of the data, and the need for robust infrastructure. Such an agreement might involve an annual license fee, usage-based fees, or a hybrid model, likely in the tens or hundreds of thousands of dollars per year, depending on the negotiated terms. This is comparable to what one might expect from other large-scale geospatial data providers like Google Maps Platform billing information for high-volume use.

How the pricing compares

Open Charge Map's pricing model—free for non-commercial and limited commercial use, with custom enterprise plans—positions it distinctly against alternatives in the EV charging data space. Most alternatives tend to be commercially focused from the outset, offering tiered subscription models or usage-based pricing for all levels of access.

Free Tier Accessibility

A key differentiator for Open Charge Map is its highly accessible free tier. Many commercial alternatives, such as PlugShare or ChargePoint, primarily focus on their own proprietary networks or monetize their data access through clear subscription tiers, even for limited usage. While some may offer developer programs or limited free access, Open Charge Map's foundational commitment to open data means a more generous entry point for individual developers, researchers, and small projects Open Charge Map developer documentation.

Open Data Philosophy

Open Charge Map's data is community-contributed and generally licensed under an open data license, which aligns with initiatives focused on open standards and collaborative development. This contrasts with proprietary databases where data ownership and licensing are typically more restrictive and come with associated costs from the first API call. The open nature can reduce initial financial barriers to entry, fostering innovation within the EV ecosystem.

Enterprise Flexibility vs. Tiered Pricing

For high-volume commercial use, Open Charge Map's enterprise plan model, based on direct negotiation, offers flexibility. This can be advantageous for large organizations with specific, complex requirements that may not fit neatly into predefined pricing tiers offered by competitors. However, the lack of public pricing means potential enterprise users must engage in a sales process to determine costs, which may require more time compared to alternatives that publish clear pricing tables for their highest tiers.

In contrast, many commercial API providers in the transportation or mapping sector, like those offering ArcGIS Platform pricing, typically provide structured pricing tiers, often based on transactions, data volume, or number of active users, allowing for more predictable budgeting. While such structured pricing offers transparency, it might not always cater to highly bespoke integration needs as flexibly as a custom enterprise agreement.

Cost Savings for Development and Prototyping

The free tier significantly reduces the cost of development and prototyping. Developers can build and test applications using real-world data without incurring upfront API access fees, which is a substantial benefit compared to platforms that impose charges from the first request or after a very small free allowance. This allows for experimentation and proof-of-concept development without financial risk.

In summary, Open Charge Map represents a cost-effective solution for many use cases, particularly those outside of large-scale, mission-critical commercial applications. Its open data model and free tier make it highly competitive for individual developers and smaller projects, while its enterprise offering allows for tailored commercial engagements.
