SIMATIC EV Charging System
Charging the evolution of eMobility.
It is essential to understand that building and installing EV charger system goes beyond providing a charging point for electric vehicles. To maximise uptime and minimise losses, you need a holistic approach to the entire electrical infrastructure.
Overview
SIMATIC: The holistic approach for a successful EV charging infrastructure
Using Siemens modular approach, we begin with the transformer substation connection to the electrical grid. The load management system helps you stay within contract limitations with your power supplier and ensures that you deliver maximum power to your customers during the charging process. The optional microgrid application enables you to integrate on-site batteries or photovoltaic generation. The integrated asset management system helps reduce service costs and ensures seamless operation. Additionally, it maximises the lifespan of your EV charging infrastructure.

SIMATIC EV Charging key components
ET 200SP TM ECC 2xPWM ST
The essential module for your charging systems
The ET 200SP I/O system offers an ideal basis for meeting the technological requirements involved in the conductive charging of electric vehicles not only in industrial automation, but also the field of electromobility. Communication between the electric vehicle and the CPU installed in the charger infrastructure plays a major role here. The ET 200SP TM ECC 2xPWM ST hereby enables communication in accordance with charging mode 3 for two charging processes running independently of one another as defined in the IEC 61851 standard. It can be used within an ET 200SP station, both in centralised and distributed configurations, whereby the slots can be freely selected.
In addition to communication, the technology module takes over control of the connector lock for charging sockets type 2 in accordance with IEC 62196 and of the contactor for switching the charging capacity.
For demanding charging infrastructure solutions, the tasks of load management (Energy Meter), back-end and billing options (Open Controller), identification (RF1060R), illumination (e.g. TM Pulse) and back-end connection (PC) can be implemented within the SIMATIC ET 200SP in combination with additional modules and a corresponding CPU (e.g. SIMATIC ET 200SP Open Controller).

Multi-point EV Charging stations
This multi-charging system is build to be able to expand it over the time to deal with the increasing number of electrical vehicles. To ensure this property both hardware and software should be focused on modularity.
The Siemens hardware offers you to build up a modular charging system by adding some charging specific hardware like the charging plug.
The ET 200SP TM ECC 2xPWM ST is the essential module for your Siemens charging system. This module builds up the communication to the car and manage the behaviour of the lock among other things.
