Creating a charging infrastructure for electric vehicles relies on a capable workforce. Professionals with knowledge in electrical engineering, renewable energy integration, grid management, and compliance are essential for the future of transportation. In this blog, we’ll briefly go over some of the skills needed by technicians to support the shift to electric transportation, with a focus on Germany and its standards. Although this is by no means an exhaustive list, and only touches the surface of the insight required to work effectively in this field, the overview should provide a starting point for engineers considering entering this space.

Electrical Engineering Expertise:

The heart of EV charging infrastructure is electrical engineering. Professionals in this field require a solid understanding of electrical systems, circuits, and power distribution. They are skilled at designing and implementing safe and efficient charging solutions. An essential standard in this context is DIN EN 62196. Part 1 of this standard deals with the conductive charging of EVs, outlining the requirements for plugs, socket-outlets, vehicle connectors, and vehicle inlets. It encompasses both AC and DC charging.

Knowledge of EV Charging Standards:

Understanding various charging standards like CCS (Combined Charging System), CHAdeMO, and Tesla Superchargers is important for ensuring compatibility and interoperability across different charging networks. Several standards play a role in this context, including IEC 61851 (Electric Vehicle Conductive Charging System), which pertains to devices for wired charging within and outside electric road vehicles at standardized alternating voltages up to 1,000 V.

Networking and Communication Protocols:

An understanding of networking protocols (e.g., OCPP, ISO 15118) and communication technologies is crucial for enabling smart charging capabilities, remote monitoring, and data analytics. DIN EN 61851-1 outlines general requirements for conductive charging systems for EVs. It includes aspects like electrical and mechanical safety, EMC (Electromagnetic Compatibility), and communication protocols.

Project Management Skills:

Effective project management ensures that charging infrastructure projects are completed on time and within budget. This includes skills in planning, scheduling, resource allocation, and risk management. Project managers, sometimes shortened to PMs, may need to consider the following when developing plans:

1. DIN EN 60664-1 (Insulation Coordination for Equipment within Low-Voltage Systems):

   • This standard addresses insulation coordination for electrical equipment, ensuring that different parts of an electrical installation can operate safely together.

2. DIN EN 50620 (Conductors of Insulated Cables):

   • This standard covers the requirements for conductors of insulated cables, which are used in various electrical applications, including EV charging infrastructure.

3. DIN EN 60947:

   • Part 1 of this standard provides general rules for low-voltage switchgear and controlgear, which are essential components of EV charging stations.
