Vector introduces vSECC.InPlug, a new communication controller board for DC charging infrastructure. The solution relocates charging communication directly to the DC charging plug, thereby enabling cable lengths of up to 100 meters between the vehicle and the charging station. This gives operators of bus and truck depots greater flexibility in planning and setting up their charging infrastructure.

With vSECC.InPlug, Vector integrates the charging communication controller directly into the DC charging plug. There, the board handles power-line communication on the plug side. Another controller, such as vSECC, remains centrally located in the control cabinet and continues to manage the charging process, the communication protocols, the power electronics, and the connection to the backend. This division of tasks allows for long cable runs between the central power electronics and the charging plug, enabling distances of up to 100 meters (328 feet) between the charging station and the vehicle. This architecture is particularly well-suited for bus and truck depots, as well as for charging infrastructures with centrally located power electronics or geographically distributed charging points. Planners gain the flexibility to position charging points directly at the vehicles’ parking spaces and to consolidate the power electronics at locations with suitable power supply and cooling.

Integration with the Smart Charging Connector from Lapp Mobility

In collaboration with Lapp Mobility, Vector has integrated the vSECC.InPlug communication board into a DC charging plug. As a result, the technology is now available as a fully integrated solution through Lapp. Manufacturers of charging infrastructure can also integrate vSECC.InPlug independently into their own connector and system designs. The solution thus supports a variety of charging architectures and integration approaches.

At IAA Transportation, Vector and Lapp are demonstrating how vSECC.InPlug works using an exhibit featuring a transparent charging plug, a control cabinet, and a miniature truck model. Visitors can clearly see the setup and the entire communication path between the vehicle, the plug, and the central charging infrastructure.

For Operators of Bus and Truck Depots

The board supports the IEC 61851, DIN SPEC 70121, ISO 15118-2, and ISO 15118-20 standards. The solution is designed for operators of bus and truck depots, as well as manufacturers of charging infrastructure, who want to flexibly decouple charging points from power electronics.

Warehouse Management System for an Operational Overview

In addition, with vCharM.DMS, Vector is launching the first depot management system designed for small and medium-sized bus depots. The solution consolidates vehicle status, parking space occupancy, maintenance information, and scheduled departures into a single operational overview. As a result, dispatch, the control center, and the workshop all work from the same data source and can identify early on which vehicles are ready for service and where action is needed within the fleet. The DMS consolidates telematics data, information from vehicle manufacturers’ backends, as well as maintenance and operational data. A map and list view display each vehicle along with its assigned parking space, current status, and next scheduled departure. Reported defects, maintenance work, cleaning, and driver handoffs are also factored into the assessment of vehicle readiness.

Depot operators can start using vCharM.DMS even before their fleet is electrified. When electric buses are added, the depot management system can be integrated with the vCharM charging and energy management system. Confirmed departure times and the required charge level are then directly incorporated into the charging schedule. vCharM plans the charging sessions, calculates the required start time for charging, and prioritizes vehicles based on operational requirements.

Building on the insights from Etherline Guard for data cables, Lapp is developing a system that will, for the first time, record the wear of power-carrying cables during operation. (Source: Lapp)
