EV CHARGING
Don't test on live customers.
EV charging issues don't always appear in architecture diagrams. They emerge when real chargers, firmware, billing flows, and operating conditions interact, usually in production.
RBT validates critical charging workflows before that happens.
THE PROBLEM
The issue was there. You just didn't find it before your customers did
Failed charging sessions
Sessions that don't start, stop unexpectedly, or behave differently across charger models and sites. Usually traced back to firmware, configuration, or protocol behavior nobody tested against real hardware.
Broken billing flows
CDRs, tariffs, payment records, and settlement data that don't match. Often invisible until a customer disputes an invoice or a reconciliation fails.
Migration disruption
Changing platforms should be routine. In practice, chargers, users, RFID cards, tariffs, session history, and billing data all need to survive the move without gaps.
Hard-to-reproduce field issues
The most expensive kind. Happens in production, can't be replicated in a test environment, takes weeks to diagnose.
WHY RBT
Real chargers. Real sessions. Engineering that follows through.
Most EV charging issues can't be found in documentation. They appear when a specific charger model, firmware version, backend configuration, and operational scenario interact in ways nobody anticipated.
RBT validates against physical chargers and systems, not assumptions. And when validation reveals a problem, we don't just hand over a report and leave. We support the fixes, integrations, migrations, and stabilization work needed to make the system production-ready.
We test against physical hardware. The charger either works or it doesn't.
Authorization, session behavior, backend communication, data consistency, tested end to end, not in isolation.
RBT reproduce edge cases and field-like conditions in a controlled lab environment before they reach live operations.
Validation without engineering is just a list of problems. RBT stays in to help fix them.
FIND YOUR SITUATION
Where do you need confidence before go-live?
WHO THIS IS FOR
Where a charging failure is more than a technical issue.
Charge Point Operators
Mixed charger fleets, platform changes, billing accuracy, roaming configuration, any of these can affect customers and revenue when something goes wrong. RBT validates that critical workflows hold before they reach live operations.
Charger Manufacturers
New charger models and firmware updates need to work reliably across different platforms and operator environments. RBT tests real charger behavior, reproduces field issues, and validates platform interactions in a controlled lab before customers encounter them in production.
CPMS / CSMS Vendors
A platform can work perfectly and still fail in a client's specific operating environment. RBT helps make implementations reliable beyond what standard onboarding covers.
Commercial Fleets & Public Transport
Depot charging that misses a window doesn't just create a support ticket, it grounds a vehicle. RBT validates charging workflows before they affect route execution and daily operations.
eMSPs and OEM Digital Teams
Roaming flows, user authorization, payment logic, vehicle and app integrations, the charging experience is only as reliable as the systems behind it. RBT supports the validation work that keeps those systems trustworthy across partner networks.
IN PRACTICE
Real validation and engineering support.
Migration Continuity Validation
A CPO migrating to a new Charge Point Management System needed assurance that chargers, users, RFID cards, tariffs, billing data, and customer-site configurations would remain consistent before and after migration. RBT helped prepare the network for migration by bringing field conditions to a stable baseline, resolving customer-site installation issues, and updating charger versions to improve consistency across the network. We also developed and implemented automated test coverage for key migration use cases, creating a validation foundation for the new platform before rollout.
Field Issue Reproduction & Diagnostics
A charger manufacturer was facing field complaints about inconsistent charging-session behavior that could not be reproduced in a standard test environment. The issue affected one of their key customers, with dozens of installed customer sites and chargers already in operation. RBT reproduced the conditions in a lab environment, isolated the firmware-protocol interaction causing the issue, and defined the remediation steps needed before the next firmware release.
EV Lab Production Readiness Validation
A new charger model needed validation before rollout to operator sites. RBT tested real charging scenarios, simulated edge cases and fault conditions, and reviewed backend communication before production.
Charging Session & Billing Integrity Validation
An e-mobility provider managing charging access across its own network and roaming partners needed reliable coordination between charging sessions, CDRs, tariffs, billing records, customer data, and reporting. RBT helped build and validate the backend layer connecting charging operations with CRM and billing systems. The work supported automated CDR processing, multiple billing models, roaming-related data flows, and end-to-end validation from physical charging events to business reporting.
ABOUT RBT'S EV CHARGING WORK
Validation with real chargers and engineering experience
RBT's work in EV charging spans OCPP/OCPI protocols, backend systems, billing flows, roaming connections, enterprise integrations, and hands-on lab validation against real chargers. We've worked with CPOs, OEMs, and e-mobility platforms across Europe, on systems where charging reliability, billing accuracy, and operational continuity are non-negotiable.
Our EV lab allows us to test what standard software environments cannot: how real chargers, firmware versions, configurations, protocols, backend systems, and fault conditions behave together. The lab supports validation across multiple charger models and configurations, and if clients need to validate against their own specific hardware, validation works with any equipment they supply.
OCPP, OCPI, billing flows, roaming, APIs, enterprise systems.
RBT understands how hardware, firmware, configuration, and backend logic interact in real conditions.
We look for what breaks before rollout, not after.

Something critical is going live.
Let's validate it first.
Whether it's a charger rollout, firmware update, platform migration, or billing integration, RBT can validate the workflows that matter before they reach production.
