Building clarity for EV charging infrastructure decisions.
Electric vehicle charging infrastructure in the United States is expanding rapidly, but the data behind it
is difficult to access, analyze, and visualize in practical workflows. Evasta connects public infrastructure
data to real planning questions: where growth is accelerating, where gaps remain, and how network
distribution changes month by month.
As EV adoption grows, charging infrastructure planning becomes more than a technical exercise — it becomes a
public-access, energy-equity, and transportation-readiness challenge. Evasta organizes that complexity into
insights that are easier to trust and act on.
Our mission
Turn raw federal EV charging data into meaningful insights.
Provide practical tools for planning and decision-making.
Support transparent, evidence-based infrastructure discussions across public and private stakeholders.
Reduce the time between data collection and practical action.
The mission is translation: taking large, technical datasets and converting them into clear, interpretable
patterns that support real decisions on expansion strategy, policy prioritization, and service reliability.
What this platform covers
State-level charging summaries with comparable metrics.
EV network and operator comparisons to assess market structure.
Plug counts and network-by-state matrices for capacity visibility.
California county and network analytics for localized planning.
Month-over-month trend tracking to identify momentum shifts.
Coverage views that reveal concentration, imbalance, and expansion corridors.
The platform bridges national and local perspectives — the breadth needed for policy and funding context,
with enough granularity to answer county-level and corridor-level questions.
02 — The value
Less time reconciling spreadsheets, more time deciding.
Why it helps
AFDC data is comprehensive, but large and complex for many users.
Raw national data becomes monthly plug-count analytics.
State-level and network-level comparisons sit side by side.
California county summaries add local trend visibility.
Highlights where investment is keeping pace with demand signals — or falling behind.
Fills a public gap with a transparent platform built on open federal data.
Better visibility leads to better decisions. Simplifying how infrastructure data is read and compared lets
teams spend their time deciding where to build next.
How the data is prepared
Public AFDC station records are collected as monthly snapshots.
Records are normalized into consistent state, network, and county views.
Plug counts are aggregated so periods stay comparable over time.
California ZIP codes are mapped to counties for local analysis.
Every summary table is published as a downloadable CSV.
Publishing the intermediate files matters as much as the charts: anyone can audit a figure, reproduce a
comparison, or extend the analysis with their own methods.
03 — Data & attribution
Every figure traces back to a public source.
Evasta is built entirely on open data. The sources, rights, and refresh cadence are listed below so any
number on this site can be checked against its origin.
Data source
Electric vehicle charging station data is provided by the U.S. Department of Energy's Alternative Fuels
Data Center. California-specific ZEV and infrastructure statistics are also informed by the California
Energy Commission's Zero Emission Vehicle and Infrastructure Statistics Collection.
The data is public and is used with attribution to the originating agencies.
