Electric autonomous vehicles promise safer and more sustainable mobility, but integrating them into charging networks presents many challenges. What do you think are the main technical obstacles—such as real-time charge management or protocol interoperability—and the legislative issues related to liability in case of an incident? Should we prioritize open standards or proprietary solutions to facilitate deployment? I’d like to hear about your experiences, studies, or projects that highlight these issues, as well as your suggestions for harmonizing practices.
What future for autonomous vehicles in charging networks? Debate on technical and legal challenges

The central question often arises: how can an autonomous vehicle "recharge" without human intervention while ensuring the legal safety of the process?
Technically, the lack of interoperability between chargers and communication protocols is the first hurdle. Today, the OCPP 1.6 standard is widely deployed, but it does not yet cover the requirements of V2G (Vehicle-to-Grid) and bidirectional charging, which are essential for an autonomous EV fleet. The ISO 15118-2/3 group, which introduces "Plug-and-Charge" and digital contract signing, is better suited, but its adoption remains fragmented; manufacturers sometimes use their own proprietary implementations, complicating the implementation of a homogeneous network. A pragmatic solution is to deploy an OCPP↔ISO 15118 translation gateway that manages the session in real time, ensuring SOC (State-of-Charge) tracking via the vehicle’s CAN-bus and adjusting charging power based on the autonomous mission’s needs.
Legally, responsibility in case of an incident during the charging phase remains unclear. Civil law stipulates the liability of the "operator’s act," but the introduction of autonomous decision-making software creates a gray area: who is responsible if the vehicle decides to leave the charging point before the safety protocol is fully executed? Some countries (e.g., Germany) are considering mandating a "certificate" of software compliance, which must be validated by a third-party authority before each OTA update. In practice, the service contract between the charger operator and the vehicle owner must clearly outline each party’s obligations, particularly the sharing of session logs for post-incident audits.
Regarding the choice between open standards and proprietary solutions, my experience with a pilot project in Scandinavia shows that open standards enable faster deployment and facilitate scalability. By using OCPP 2.0 combined with ISO 15118-3, we were able to integrate chargers from three different manufacturers without resorting to specific adapters. This reduced integration costs by 30% and simplified software update management. Of course, manufacturers may protect their interests with proprietary extensions, but these must remain backward-compatible with open protocols to avoid market fragmentation.
In summary: I advocate prioritizing open standards (OCPP 2.0 + ISO 15118) while implementing an abstraction layer that manages real-time charging and ensures legal traceability. This not only harmonizes practices between operators and manufacturers but also provides a solid foundation for liability in case of incidents, which is essential for public trust in autonomous vehicles.
The real-time charge management problem in autonomous EVs is quite similar to what we faced with Qualcomm’s Quick Charge ecosystem a few years back—the phone had to negotiate voltage and current on the fly, and manufacturers had to agree on a common handshake. In the case of autonomous cars, you're dealing with a much larger power envelope and a moving platform, so the charger needs to predict the vehicle’s state of charge, upcoming route, and even traffic conditions to schedule a top-up without stopping. Compared to today’s static DC fast-charge stations, the protocol stack has to be far more dynamic, which is why many OEMs are pushing for an open OCPP-2.0-based interface that can be extended with real-time telemetry instead of proprietary “black-box” APIs that lock you into a single brand.
Legally, it’s a lot like the liability debate around self-driving smartphones (think of the “phone-while-driving” lawsuits). If the charger supplies power based on the car’s autonomous decisions, responsibility for a fire or overcharge could fall on the vehicle’s software provider, the charger operator, or even the network manager. The safest route is to adopt an open-standard model—similar to the USB-PD specification—so that compliance testing, audit trails, and firmware updates can be jointly overseen. Proprietary solutions might speed up rollout for a single manufacturer, but they’ll complicate cross-brand liability and make regulators nervous. In practice, a hybrid approach works best: an open core protocol for safety and interoperability, with optional proprietary extensions for brand-specific features, just like how Android phones use the open Android OS but can add Samsung’s DeX layer on top.
I wonder how real-time load management impacts the reliability of autonomous vehicle control systems when demand peaks on the network. Have you ever tested open interoperability protocols that ensure clear accountability in case of an incident?
Are open standards like OCPP already capable of handling real-time charging for autonomous vehicles, or do we still need specific extensions? And legally, who is responsible if the car can't find an available charging station and causes an accident while searching for a recharge?
Thanks for bringing up this topic—real-time load balancing and the lack of interoperable charging protocols are the biggest technical hurdles, while unclear liability frameworks make legal compliance tricky. Do you think adopting an open-source communication stack could ease both issues, or would manufacturers push for proprietary solutions anyway?
