I have an quite big CSv File I want to have in Google Maps or just on a map. These are just coordinates but I have 600.000 of them..
Do you have any Idea how I can do this?

The easiest way to do this is generate a KML file (see http://code.google.com/apis/kml/articles/csvtokml.html for a possible solution). You can then open that up in Google Maps by storing it online and linking to it from Google Maps as described at http://code.google.com/apis/kml/documentation/whatiskml.html
EDIT: http://www.gpsbabel.org/ may let you do it without coding.

We have now (jan2017) a csv layer import inside Google Maps itself.
Google Maps > "Your Places" > "Open in My Maps"

GPS Visualizer has an interface by which you can cut and paste a CSV file and convert it to kml:

Then use Google Earth. If you don't have Google Earth and want to display it online I found another nifty service that will plot kml files online:

none of that needed.... just go to:
http://www.gpsvisualizer.com/
now and load your csv file as-is. extra columns and all. it will slice and dice and use just the log & lat columns and plot it for you on google maps.

For generating the KML file from your CSV file (or XLS), you can use MyGeodata online GIS Data Converter. Here is the CSV to KML How-To.
