From 8 January 2026, all publicly accessible charge points must comply with EN ISO 15118-1 to -5.
From 1 January 2027, EN ISO 15118-20 will also be mandatory, including for private or semi-public stations.
Compliance is therefore pivotal to ensure interoperability, security and future-proof electric vehicle (EV) charging.
Against that backdrop, Elecq reported that its chargers successfully passed all ISO 15118-1 to -5 test cases using Keysight equipment.
The milestone reduces integration friction, improves vehicle compatibility and lays the groundwork for Plug & Charge and V2X functions.
“Keysight provides ISO 15118 protocol test equipment to various certification bodies and renowned test laboratories,” explains Jay Wen, Elecq’s CEO and co-founder, speaking to Mobility Portal.
“Passing all the test cases indicates that Elecq’s AC charger has achieved a market-leading level of conformance with ISO 15118-1 to -5,” he adds.
Regarding product availability, the Home Series supports ISO 15118 on selected models, whereas the Biz Series offers coverage across the entire range.
“We are committed to offering charging solutions that not only meet upcoming regulations but are also ready for the evolution of mobility,” says Jen.
What does ISO 15118 enable on AC?
ISO 15118 compatibility in alternating-current chargers unlocks core capabilities for the next phase of infrastructure:
- Smart load balancing: optimises power distribution, avoids peaks and reduces operating costs.
- Plug & Charge (integrated authentication and payment): securely pairs vehicle and charger, streamlines billing and removes cards or apps.
- Bidirectional power flow (V2X): prepares V2G (vehicle-to-grid) and V2H (vehicle-to-home) scenarios as regulation and vehicles permit.
V2G continues to draw attention across the industry. There are pilots in several regions reporting positive results and practical regulatory and technical lessons.
“As the number of electric vehicles grows, they will cease to be mere consumers; they should act as distributed storage and participate in grid dispatch,” notes Jay.
“At Elecq we see this as an inevitable trend,” he adds.
Why conformance testing matters
Passing ISO 15118 tests is not a box-ticking exercise: it reduces the risk of incompatibilities across brands, secures the communication layer between vehicle and charger, and speeds up commissioning.
For operators and builders, that translates into lower integration costs, fewer field incidents and a better user experience.
Role of interoperability test labs
Elecq follows an open collaboration strategy.
In addition to its own labs, it actively participates in interoperability testing organised by sector alliances and organisations to validate real-world scenarios with multiple OEMs.
“We invite all electric-vehicle manufacturers to contact us at any time to carry out interoperability tests,” says Jay.
