How to set "measurement" with code

[github-ps1304]

Hi - can you help me with you script?
Example csv:

timestamp,Ladezustand,Batterie,Batterie (Entladen),Netzeinspeisung,Netzbezug
01.05.2021 00:00,59,0,122,1,1
01.05.2021 00:00,40,0,140,5,2

my dbname is "test" - how to set "measurement" in influxdb correct with your script when trying to access
the data via Grafana? from my perspective measuremtn should contain all names in the header row like Ladezustand etc.
the values below should be visible as values

For example a Grafana query looks like this:

SELECT last("Leistung") FROM "Batterie" WHERE $timeFilter

where "Leistung" should be a value from csv above eg: 122, "Batterie is the column header name and one measurement
