Operational Support Services for Charging Network Operators

End-to-End Testing

Our comprehensive QA solutions, including virtual charger simulation, protocol testing, integration testing, and automated front-end testing, ensure your charging network is reliable, compliant, and ready for real-world scenarios, every day.

Level 2 Support

Identify and resolve issues like abnormal charger behavior, payment discrepancies, and roaming problems through comprehensive troubleshooting, on-demand QA testing, and log analysis. Protocol experts are ready to scrutinize every charging session.

Charger Onboarding

Onboard new charger makes and models through comprehensive interoperability testing. We develop and execute robust test cases, resolve issues with manufacturers and CSMS vendors, and conduct regression testing, field commissioning validation, and network inventory documentation. Any issues are handled by our seasoned OCPP engineers, members of the OCA.

Reliability Engineering

We help define KPIs and monitor network performance, iterating for continuous improvement. By optimizing availability, systems uptime, and CSMS response times, we maintain accountability and provide alerts for e.g. traffic anomalies. Develop and maintain scaling strategies for peak periods to ensure customer satisfaction, network utilization, and revenue growth.

How we can help

Draw from our extensive institutional knowledge in building and maintaining OCPP and OCPI-based CSMS and CPO platforms, managing well over 100,000 EVSEs. Our extensive industry experience across multiple regions and markets enables us to offer expert Level 2 and Level 3 support, backed by a wealth of experience in resolving thousands of cases.

  • Stress and Load Testing: Operating a charging network is challenging under the most normal circumstances. Add a travel holiday or marketing campaign and it could put your systems and architecture to the test. Proactive performance testing, using real-world scenario modeling, done by experts with domain knowledge, can be the difference that sets you apart from the competitors. 
  • End-to-End Testing: Continuous testing and QA work can find issues before they become incidents. An E2E approach gives a holistic view and transparency into the black box of systems involved. An example of this is an automated frontend framework, testing actions on a mobile app interface on one end, spanning the app’s backend, transacting with a CRM system for customer data, whilst triggering actions on a CSMS, that at the other end, that finally interacts with a charger over a VPN. We’ll find the culprits, bottlenecks, and ways to enhance that customer experience.
  • Roaming Integrations: Even the best of OCPI implementations have their quirks. Not only new roaming connection setups can be time-consuming. Add a handful of roaming partners and month-end CDR and invoice reconciliation could easily become a hassle. Systems out of sync, connections that need to be moved, or EVSE’s with new IDs - we have seen it all. 
  • EVSE Model or Firmware Updates: New charger models need thorough testing against the CSMS. Test cases, discussions with manufacturers, and tweaks to configuration are all things necessary. Even an already on-boarded charger model might need regression testing upon new firmware releases or changes in the CSMS. We’ve rolled out thousands of updates over the years, on both sides of the OCPP ecosystem and planning is key.
  • Migrating Chargers: Perhaps a change of CSMS or taking over a population of chargers from another vendor. Batch EVSE migration sounds easy in theory but needs to be proactively planned, flawlessly executed, and carefully monitored. All to ensure up-time, a great customer experience and prevent loss of data or even revenue.
  • Liaison & Representation: We can act as a liaison between system or infrastructure vendors and your business operations, speaking the language of both. Examples of this are the areas of setting up and managing Internet/Telco-related infrastructure (e.g. DNS, certificates, gateways, hosting, sysops) together with cloud providers or other IT services companies. Other areas are for example communication with EVSE manufacturers around interoperability problems, or external parties on either side of your vital SaaS integrations.
  • Incident Response and Investigation: Having monitoring and alarms on the infrastructure is necessary, but incidents will occur at the most inconvenient of times. Trust us to help with Level 2 support, diagnose and troubleshoot the technical reasons behind an issue and suggest improvements not only isolated to the case at hand but to enhance reliability overall. Coming from the EV software world, we have protocol experts, QA and software engineers that can drill down to levels that often no one else can.
