8 good reasons to rely on Siemens Technology in your charging stations

The perfect interaction of SIMATIC, SENTRON and SIRIUS
Icon charge E-Car

Charge any e-car with any voltage – standard compliant

With only 3 charge control modules you will be able to charge with the following connector types according to latest international standards.

  • AC: Type 1-3, GB/T
  • DC: CCS, CHAdeMO, Tesla SuC connector types (via CSS adapters)

With Siemens automation and electrical components, it is possible to charge AC and DC with an output up to 1000 V (depending on converter performance) and up to 3 phases AC. The charging station will be highly performant and future proof.

Icon scalable, space saving and customizable solution

Highly scalable, space saving and customizable solution

Due to the master-slave solution design it is possible to realize charging stations of ANY size from single pillars to multi point charging with many charging sockets or plugs.

 

The clue?  The innovative concept differs from conventional pillar solutions and offers minimal space:

  • There is only minimal space required for sockets or plugs in the parking space. 
  • The distance between control cabinet and charging point can be 30 m and more! 
  • All hardware is mountable on DIN rails in a central control panel.
Icon performance for maximum system availability

Highest controller performance for maximum system availability

All automation task run on one single and performant device what eliminates redundant and risky interfaces.

Especially for a high number of charging points only one controller is needed compared to common solutions in the market.

Siemens controllers are designed to run reliably under the most adverse circumstances.

Icon Charge Controller for OCPP communication and Load Management

State-of-the-art Controller Technology: Ready for OCPP communication, Load Management and calibratable metering integrable

The controller platform includes secure VPN (over 3G, LAN, WiFi) to communicate with backend systems, e.g. for billing purposes and more. Free application examples for the SIMATIC controllers support the Open-Charge-Point-Protocol (OCPP). Both is required to create modern stations. 

 

A basic load management is included into the SIMATIC controller platform. For advanced load management the SIMATIC Energy Suite is recommended.

 

For calibratable metering (e.g. according to German “Eichrecht”) the meter “EDL40+” can be used together with SIMATIC. In addition, for individual charging poles the Siemens SENTRON PAC2200 offers a PCB compliant solution.

Icon easy and fast programming

Free application examples for easy and fast programming

For an easy start our customers receive free-of-charge application examples that can easily adapted and extended in the TIA portal (projection and programming environment for SIMATIC controllers).

Icon safe and robust electrical components

Safe and robust electrical components

SIRIUS and SENTRON ensure protection of the user - people and the car.

Reliability is key in this context - especially as charging infrastructure is exposed to all kinds of weather conditions, electrical equipment needs to be robust and of high quality.
