Abstract

En batteripakke kan inkludere én eller flere battericeller, strømblokkerende transistorer og et batteristyringssystem. De beskrevne implementasjoner håndterer overstrømmer trukket fra battericellene som forårsaker ustabil drift av batteristyringssystemet. Overstrømmene håndteres uten å forårsake et uønsket fall i spenningsutgangen fra battericellene. De beskrevne implementasjoner kan håndtere overstrømmer selv om overstrømmene forårsaker at batteristyringssystemet forskyvningsspenning faller under et minimum driftspenningsnivå for en bestemt tidsperiode. De beskrevne implementasjoner bruker strømblokkerende transistorer som kan figureres til å blokkere strømflyt og sikre sikker drift av battericellene i tilfeller strømmen strukket fra battericellene ville være tilstrekkelig høy for en tilstrekkelig lang tidsperiode til å forårsake skade på battericellene.
