Develop Charging Stations and Wallboxes

For Charging Station OEMs, Wallbox Manufacturers and Heavy-Duty Infrastructure Developers

Vector’s product families vSECC and vSECClib are field-proven communication controllers and software libraries that reduce integration effort to a minimum for wallbox, charging station and heavy-duty DC charging manufacturers. They cover CCS, CHAdeMO, NACS with ISO 15118-2 and ISO 15118-20 including Plug & Charge, BPT, V2G, OCPP 1.6, OCPP 2.0.1, OCPP 2.1 and AFIR compliance, across AC and DC wallboxes, AC and DC charging stations and megawatt charging systems.

Which Type of Charging Infrastructure Are You Developing?

The vSECC family and vSECClib cover infrastructure types from compact residential wallboxes to multi-megawatt heavy-duty charging. Each type has distinct requirements for power level, form factor, communication protocols, regulatory compliance and hardware integration depth.

Wallboxes

AC and DC wallboxes and compact charging points for home, workplace, parking and fleet use. Compact form factors, cost-sensitive designs and varied installation environments require flexible controller options including board-level integration and extended temperature variants. ISO 15118-20 bidirectional charging adds both grid-serving and off-grid capability to AC and DC wallbox designs.

Charging Stations

AC and DC charging stations and fast chargers for public networks, parking facilities, fleet depots and commercial sites. Requires full support for ISO 15118-2 and ISO 15118-20 including Plug & Charge and bidirectional V2X and backend communication via OCPP. AFIR compliance requirements apply to all public charging infrastructure in the EU.

Heavy-Duty Charging

High-power and automated DC charging systems for electric trucks, buses, port equipment and industrial vehicles. Heavy-duty applications require charging via CCS or MCS, as well as pantograph charging using OppCharge or SAE J3105. MCS operates at power levels beyond standard DC charging and requires dedicated communication architecture. Bus and depot environments involve VDV 261 for fleet bus preconditioning and operational communication.

Extended Cable Distances and Smart Power Distribution

Fleet depots and high-utilization sites often require charging points to be placed far from central power electronics, or need to share power electronics dynamically across multiple charging points. vSECC.InPlug moves PLC into the connector and enables cable lengths of up to 100 meters. Combined with vSECC and Smart Power Distribution, it supports scalable off-site charging layouts.

Scale Charging Infrastructure

Off-the-Shelf or Custom Solution?

Two integration paths allow manufacturers to decide how much of the hardware platform they want to develop themselves. The right choice depends on the expertise in hardware design and embedded software.

Communication Controller

Use ready-to-integrate Vector communication controllers for your charging station or wallbox. The vSECC family covers all power levels and form factors: plug-on PCB for compact wallboxes, full DC or megawatt station controllers and small controller designed to fit into the charging plug. Each variant ships with a software platform, together replacing the individual components you would otherwise source, qualify and integrate separately. Charging communication interoperability, V2G grid code compliance, Plug & Charge and AFIR compliance are handled by the platform.

Software Library

Implement the full charging communication on your own controller hardware using vSECClib. A library dedicated to the charging interface covers DIN SPEC 70121, ISO 15118-2, ISO 15118-20 including bidirectional AC, DC and MCS charging and Plug & Charge. Wireless and pantograph charging are also supported. Another library dedicated to the management interface covers OCPP 1.6, OCPP 2.0.1 (IEC 63584) and OCPP 2.1 (in development). For manufacturers who own their controller hardware and want to implement the full charging communication stack on their own embedded platform without using a Vector controller.

Which Vector Solution Fits Your Charging Station Design?

Several hardware variants and software libraries cover the full range of communication requirements for charging stations and wallboxes. Every hardware variant integrates the components and software that would otherwise need to be sourced and qualified separately, reducing procurement, integration and certification effort. Choose based on charging type, power level, form factor and whether you prefer Vector hardware or your own embedded platform.

Which Charging Communication Standards Do the vSECC Products Support?

The vSECC and vSECClib products cover the full range of vehicle-side and backend charging standards across all power levels. Support for evolving standards is designed to be updateable without requiring a full communication layer redesign.

VEHICLE COMMUNICATION

EV and EVSE Charging Protocols

ISO 15118-2 (AC and DC, Plug & Charge)
ISO 15118-20 (bidirectional, multi-service, Plug & Charge)
DIN SPEC 70121
CHAdeMO
NACS (SAE J3400)
OppCharge / SAE J3105 (pantograph)
VDV 261 (fleet bus preconditioning)

Protocol coverage varies by product. See individual product pages for the exact supported standards per variant.

BIDIRECTIONAL CHARGING AND V2G

Vehicle-to-Home and Grid-Serving Charging

ISO 15118-20 BPT (DC bidirectional)
ISO 15118-20 AC DER (grid-forming and grid-supporting)
OCPP 2.1 (in development)
Smart charging and dynamic load management
Interface to energy management systems

Bidirectional charging via ISO 15118-20 enables wallbox and station manufacturers to add V2G and grid-serving capability to their products.

BACKEND AND NETWORK

Charge Point Management and Grid Integration

OCPP 1.6
OCPP 2.0.1 (IEC 63584)
OCPP 2.1 (in development)
Compatible with all major CPMS platforms
Dynamic load management via smart charging profiles
OCA certification achieved with customers

OCPP 2.0.1 introduces device management, enhanced security and smart charging capabilities beyond OCPP 1.6.

REGULATORY COMPLIANCE

EU and International Regulatory Requirements

AFIR (EU Alternative Fuels Infrastructure Regulation) ready
ISO 15118-2 and -20 as required by AFIR for AC and DC public and private charging
OCPP certified as required by CALeVIP (California Electric Vehicle Infrastructure Project)
Designed for evolving international implementation requirements

AFIR requires all new public charging points deployed in the EU from 2025 onward to support ISO 15118.
