Specialist translations for charging infrastructure, charge management and the eMobility ecosystem.
From the OCPP backend to the wall box user manual. From AFIR compliance through to your end-customer app. COMLOGOS speaks the language of charging.
ISO 17100 · ISO 18587 · DIN EN 61439 expertise · Over 40 languages
By 2026, eMobility has reached a decisive phase: it is no longer a pioneering niche, but a scaling mass market. With over 196,000 public charging points in Germany, pure electric vehicles accounting for aroand 26% of new registrations, and full regulatory coverage through AFIR, charging infrastructure has become a critical pillar of the transport transition. Behind this figure lies a complex ecosystem: wall box manufacturers, charge point operators, eMobility service providers, backend platforms, energy suppliers and grid operators. All of these are active in the market simultaneously and are oriented towards the international market. They are all dependent on precise multilingual communication.
This is exactly where we come in. COMLOGOS has many years of experience translating technical documentation in the field of electrical and energy engineering and is bringing this expertise to the specific language world of eMobility. OCPP backends, ISO 15118 Plug & Charge, AFIR-compliant charging network terms and conditions, wall box operating instructions and app localisation. We are familiar with the relevant standards and protocols, and we anderstand the difference between consumer-facing content and backend API specifications.

What COMLOGOS means by 'eMobility'
The term 'eMobility' is used in many different ways across the market. To help you anderstand which translation services you will find on this page and which are better handled on one of our other industry pages, we have provided a clear breakdown below:
| On this page: eMobility | Sister pages |
|---|---|
| Charging infrastructure (AC, DC, HPC, MCS) | → Automotive: vehicle development, electric powertrain, OEM/Tier processes |
| Charging management and backend software (OCPP 2.0.1, OCPI, OICP, eRoaming) | → Battery Technologies: cell chemistry, cell production, cell-level BMS, recycling, stationary storage systems |
| Charge Point Operator (CPO) and e-mobility service providers (EMP) | → Electrical Engineering & Digital Industry: power electronics in general, component level |
| Grid integration, V2G/V2H, charging management | → Control Cabinet Manufacturing & Control Systems Technology: switchgear for charging parks |
| Calibration law, AFIR compliance, fanding | — |
| End customer communication (app UI, terms and conditions, marketing) | — |
At COMLOGOS, eMobility encompasses the entire ecosystem surroanding the charging of electric vehicles. We translate the specialist language of charging infrastructure, its software, the grid and the service layer. However, we do not translate the language of vehicle development itself (that's Automotivethe remit of Automotive) or battery cells (that's the remit of Battery Technologies). Battery Technologies).
A market ramping up: eMobility in numbers
eMobility is growing, and with it the need for precise, multilingual specialist communication. Three figures that illustrate this growth:
(as of 1 February 2026, Federal Network Agency)
+34% year-on-year increase.
+43.2% (KBA annual report)
The Federal Network Agency reported 196,353 publicly accessible charging points as of 1 February 2026, of which 49,904 are fast-charging points. This represents an increase of 17% on the previous year and a 34% increase for fast charging alone. The available charging capacity increased from 6.38 to 8.28 gigawatts in one year.
At the same time, the Federal Motor Transport Authority (KBA) reported 545,142 new registrations of battery electric vehicles (BEVs) in Germany in 2025, accounting for 19.1% of new registrations. This is a record since statistics began to be collected. By April 2026, the BEV share of new registrations had reached 25.8%.
Drivers of this momentum
Three regulatory and technological factors are accelerating the market ramp-up:
- AFIR (EU Regulation 2023/1804, effective from 13/04/2024): mandatory fast charging points every 60 km along the TEN-T core network, obligation to offer contactless payment from 50 kW, EN ISO 15118 support required for new installations from 08/01/2026.
- Expansion of ultra-fast chargers (> 299 kW): +44% year-on-year. One in three fast chargers in Germany now delivers more than 299 kW.
- Internationalisation of value chainsChinese manufacturers (BYD: +706% in registrations), US backend providers, Korean wall box OEMs are all entering the DACH market, creating a need for translation services.
Each of these figures translates concretely into: text. Manuals, software strings, terms and conditions, data sheets, training materials, app content. In an ever-increasing number of languages and at an ever-increasing speed, while always remaining regulatorily precise.
Sources: Bandesnetzagentur charging station register (as of 1 February and 1 April 2026); KBA annual report 2025; National Coordination Office for Charging Infrastructure. All figures are as of May 2026 and are not guaranteed; applicable regulations take precedence.
Five segments, one language: We translate all of them.
The field of eMobility is not monolithic: it breaks down into five segments, each with its own terminology, standards and target audiences. We translate for each of these segments:
Charging infrastructure (hardware)
AC charging points (3.7–22 kW), DC fast chargers (50–150 kW), HPC (high power charging, 150–400 kW) and MCS (megawatt charging system for electric trucks). We translate operating instructions, installation manuals, maintenance documentation and data sheets for wall box manufacturers, CPOs and EPCs.
Charging management and backend software
OCPP 1.6/2.0.1, OCPI, OICP, eRoaming hubs, smart-charging algorithms, load management and dynamic tariffing We also translate API documentation, software UIs, technical specifications and white papers.
CPO & e-mobility service provider (EMP)
The charge point operator runs the charging station and the EMP/EMSP runs the app. We translate terms and conditions, privacy policies, tariff communication, push notifications, in-app strings and end-customer FAQs — everything between the charging point and the user.
Grid integration, V2G/V2H, charging management
bidirectional charging (V2G/V2H/V2X), grid-serving load shifting, virtual power plants, Plug & Charge per ISO 15118-20. We also translate white papers, studies, pilot project documentation and interface descriptions for energy suppliers.
Calibration law, AFIR compliance and fanding
Measurement and Calibration Act (MessEG), calibration law compliance, AFIR reporting, KsNI fanding applications and National Coordination Office for Charging Infrastructure. We translate normative and legal texts, compliance documentation and fanding materials.
Standards and norms we speak
For eMobility texts, it is essential that the terminology matches the standard exactly. With us, it's not guesswork: our specialised translators know these standards inside out.
| Area | Standard / Norm | Relevance |
|---|---|---|
| Connector & vehicle-to-station communication | IEC 61851, IEC 62196 (Type 2, CCS Combo 2), CHAdeMO, MCS | Charging process, connector systems, AC/DC |
| Plug & Charge / authentication | EN ISO 15118-2:2016 (AFIR-mandatory at new AC points from 1 August 2026), ISO 15118-20:2022 (from 1 January 2027) | Automatic authentication, bidirectional charging |
| Backend communication station-to-CPO | OCPP 1.6, OCPP 2.0.1 | Control, status, billing data |
| eRoaming station-EMP | OCPI 2.2.1, OICP 2.3 | Tariff exchange, authorisation, CDR |
| Data reporting to authorities | DATEX II (mandatory from 14/04/2026, AFIR Art. 20) | Static and dynamic charging infrastructure data |
| Calibration law | MessEG and MessEV requirements | Consumption billing accurate to the kWh |
| Safety and grid connection | VDE-AR-N 4100, IEC 61439, IEC 61140 | Installation, protection classes, grid connection conditions |
Why eMobility translations are different
eMobility texts walk a fine line: they must be technically accurate (standards, protocol names, kWh values, connector types), they must be legally soand (terms and conditions, AFIR mandatory disclosures, calibration law, PSD2 compliance for payments), and they often need to be comprehensible to end customers at the same time, because the driver of an electric sedan isn't an electrical engineer.
We regularly encounter four specific challenges:
Firstly: Multi-stakeholder texts
A wall box manual, for example, must address the electrician (installation, VDE 0100, Type B RCD), the home-owner (commissioning, app pairing) and the service technician (error codes). Three tones, one document, one language. In translation, this layering must be preserved, with technical terminology used for the professional section, clear everyday language for the end-customer part and exact error code translations for servicing purposes.
Secondly: Software UI with character limits
Texts on a charging station display or in a wall box app often have strict character limits. 'Authentication failed — please present your card again' must fit in seven languages without being cut off. This requires experience of working with string files (XLIFF, JSON, .po and .properties) and the ability to creatively shorten text in the target language without losing meaning.
Thirdly: Hybrid of B2B tech and B2C marketing
A CPO annual report describes load management algorithms and, at the same time, the 'intuitive charging experience' for end customers. The translation must hit both registers: precise in the technical part and engaging in the marketing part. See also our service. Marketing Translation & Transcreation.
Fourth: Regulatory half-life
AFIR added the ISO 15118 requirement in 2025, which will take effect on 8 January 2026. DATEX II reporting obligation from 14/04/2026. Deadlines like these can quickly make texts outdated. We work with translation memory systems and terminology databases,enabling us to implement updates quickly, consistently and safely across different versions. This significantly reduces time-to-market with every standards change.
