Abstract

Apparatur, fremgangsmåte og datamaskinprogramprodukt for batteristyring. I en utførelse, en fremgangsmåte for kommunikasjon. Fremgangsmåten inkluderer å muliggjøre bestemmelse av når en batteripakke er koplet til en innretning, hvor batteripakken inkluderer et batteristyringssystem. Fremgangsmåten inkluderer også generering av et vilkårlig tall i batteristyringssystemet, hvor batteristyringssystemet inkluderer batterimonitoreringskretser, en prosessor, minne og en generator av vilkårlige tall. Fremgangsmåten inkluderer bruk av det vilkårlige tallet for å gjennomføre autentisering, og dersom autentiseringen lykkes, å åpne for kommunikasjon mellom batteripakken og innretningen.
