The Problem
EV charging is getting too complex to test in the field
The industry is moving faster than traditional QA can keep up. Regulations, protocols, and grid complexity are compounding — and failures in the field cost millions.
NEVI Compliance Pressure
$5 billion in federal funding requires OCPP 2.0.1, OCPI 2.2.1, and ISO 15118 compliance. Testing against every requirement with physical hardware is slow, expensive, and error-prone.
Validate compliance in software before your certification deadline.
Smart Charging Complexity
Modern algorithms must handle TOU rates, demand charges, demand response events, V2G, solar integration, and battery storage simultaneously. Testing in production is risky.
Benchmark algorithms against real grid constraints in a safe sandbox.
Costly Grid Over-Build
Fleet depots and charging sites routinely spend $50K-$500K on grid planning. Many still rely on spreadsheets, leading to over-sized infrastructure or unexpected demand charges.
Model energy costs and right-size your infrastructure before capital commitment.
Interoperability Nightmares
100+ charger OEMs, dozens of CSMS vendors, multiple protocol versions. Every new combination needs testing, and vendor-specific quirks break integrations in the field.
Test every charger-CSMS combination virtually, at scale, in CI/CD.
Three Products, One Platform
Cover the full lifecycle of charging infrastructure
No other vendor combines protocol testing, energy simulation, and digital twin capabilities. ChargerTwin connects what the industry has kept fragmented.

Who It's For
Purpose-built for every player in the EV charging ecosystem
Whether you're building the software, deploying the hardware, or operating the network — ChargerTwin accelerates your path to production.
CSMS Vendors
Need to test OCPP 2.0.1 compliance and multi-vendor charger compatibility before shipping
Replace physical test labs. Cut QA cycles from weeks to hours.
Charge Point Operators
Need to model energy costs and validate configs before site deployment
Save $50K-$500K in avoided grid overbuild per site.
Fleet Operators
Electrifying depots is complex — need to right-size grid, chargers, and schedules
One platform replaces multiple consultants and spreadsheets.
Charger OEMs
Need to test firmware OCPP compliance against multiple CSMS backends
Accelerate certification and reduce field failures.
Pricing
Invest a fraction of what a single site costs to deploy
A simulation that saves you from one grid overbuild pays for itself many times over. Start free, scale as your network grows.
