EV Charger Testing
Find EV charger issues before deployment
Communication failures between chargers, vehicles and energy systems can delay rollout and disrupt charging. Resillion tests how your EV chargers work with these systems and checks them against relevant standards. You get clear test results to help you find problems early and prepare for deployment.

Helping organisations improve quality, resilience and delivery confidence across complex digital estates.
EV charger testing for connected energy systems
Resillion tests whether your EV charger meets relevant standards and works with the systems it connects to. We check communication and performance across vehicles, charging management platforms and grid systems, giving you clear results before deployment.
Our experience spans energy systems and charging standards, including OpenADR, EREC G99, IEEE 1547, IEC 61850 and OCPP. We use controlled test environments and repeatable tests to investigate how connected charging ecosystems work together.
We work with your existing tools and development process to test early, identify problems and document the results. Our Total Quality approach connects this testing with your wider product quality needs.
BENEFITS
How EV charger testing helps you
Understand how your charger performs, where problems remain and what needs fixing before rollout.
Clear test evidence against relevant standards
Fewer problems during rollout
Reliable connections across vehicles, platforms and grids
Problems found earlier through simulated testing
Clear results to guide release decisions
Less repeated work with reusable tests
Challenge
Octopus needed to prove that its EV, bidirectional charger and software could work together safely, securely and compliantly for Vehicle-to-Grid export under G99 requirements.
Approach
Resillion led the compliance and evidence plan, using PNDC’s controlled whole-energy-system environment to test Octopus’s complete V2G setup. The team managed test planning, shakedown cycles, formal G99 testing, cyber security review and evidence capture across automotive, charging, cloud and grid stakeholders.
Result
Octopus achieved G99 certification and ENA Type Test Register support, creating the evidence base needed for commercial rollout of a secure, grid-ready V2G customer offering.
WHY US?
What our testing delivers
Our tests show how your charger performs and help your team decide what to fix before release.
Conformance testing
What this does for you
You validate charger behaviour against required protocols and standards.
Result
Evidence of performance against standards
Interoperability validation
What this does for you
You confirm charger performance across vehicles, platforms and grids.
Result
Lower deployment risk
Testing in simulated conditions
What this does for you
You find issues earlier in controlled test environments.
Result
Quicker fixes
Protocol behaviour checks
What this does for you
You understand how your charger communicates under real conditions
Result
More reliable system communication
G99 readiness support
What this does for you
You prepare test evidence to support assessment against grid connection requirements.
Result
Clearer evidence for approval applications
OCPP validation
What this does for you
You prove backend-to-charger communication works as expected.
Result
More confidence in day-to-day operation
Reusable tests and tools
What this does for you
You use existing tests and tools rather than rebuilding them for each project.
Result
More efficient delivery
Clear test reports
What this does for you
You give reviewers clear results showing what passed, what failed and what needs further work.
Result
Better-informed release decisions
WHY NOW?
Why test before rollout?
Gaps in testing can leave problems undiscovered until your chargers are in use.
Charger faults missed before deployment
Incomplete test results across connected systems
Communication problems that delay rollout
Too few operating conditions tested before launch
Extra manual work from rebuilding tests
Unclear evidence for release and approval decisions
