Med mindre ladebrikken virker, begynner ikke ladeøkten.

Med mindre means unless.

It introduces an exception or condition:

• Med mindre X, Y = Unless X, Y

So in this sentence, the idea is that the charging session will not start unless the charging tag works.

It is best learned as a fixed expression rather than word-for-word.

Here virker means works or functions.

The verb å virke can have more than one meaning in Norwegian, including:

• to work / function
• to seem / appear

But with ladebrikken, the natural meaning is functions properly.

This is because Norwegian is a V2 language. That means the finite verb normally comes in the second position in a main clause.

The opening part Med mindre ladebrikken virker counts as the first element. So the main clause must begin with the verb:

• Med mindre ladebrikken virker, begynner ...

If you put the main clause first, the word order becomes more straightforward:

• Ladeøkten begynner ikke med mindre ladebrikken virker.

Both versions mean the same thing.

After inversion, Norwegian often places ikke before a full noun phrase subject like ladeøkten.

So this is natural:

• ..., begynner ikke ladeøkten

A pronoun subject would usually come before ikke:

• ..., begynner den ikke

So the position of ikke is tied to normal Norwegian sentence rhythm and subject placement.

They are compound nouns, which are very common in Norwegian.

• ladebrikken = lade

  • brikken
  • lade relates to charging
  • brikke can mean a chip, tag, token, or fob
  • so this is something like the charging tag/fob

• ladeøkten = lade

  • økten
  • økt means a session or period of activity
  • so ladeøkten means the charging session

English often uses separate words where Norwegian prefers compounds.

The ending -en is the definite form, corresponding to English the.

So:

• en ladebrikke = a charging tag
• ladebrikken = the charging tag

And:

• en ladeøkt = a charging session
• ladeøkten = the charging session

Instead of a separate word like the, Norwegian often adds the definite ending directly to the noun.

Norwegian often uses the present tense for:

• general rules
• instructions
• system messages
• future results that follow from a condition

So virker and begynner are completely natural here.

In English, we might think of it as either:

• If the charging tag works, the charging session starts
• If the charging tag works, the charging session will start

Norwegian often does not need a separate future form in this kind of sentence.

Sometimes hvis ikke can be close in meaning, but med mindre is the more direct and idiomatic way to say unless.

• med mindre = unless
• hvis ikke = if not

So in this sentence, med mindre is the better choice because the meaning is specifically an exception condition.

The comma separates the subordinate clause from the main clause.

• Med mindre ladebrikken virker = subordinate clause
• begynner ikke ladeøkten = main clause

This kind of comma is normal in Norwegian when a subordinate clause comes first.
