▁▁ ▁The ▁Energy Bus ▁physical ▁interface ▁consists ▁of ▁the ▁plug ▁and ▁socket ▁used ▁to ▁connect ▁battery ▁pack s , ▁battery ▁charg ers ▁and ▁other ▁components . ▁The ▁ ▁conne ctor ▁used ▁was ▁designed ▁by ▁Rosen berger ▁( de ) ▁and ▁contains ▁six ▁contacts : ▁▁ 2 ▁medium ▁p ins , ▁for ▁DC ▁power ▁transfer ▁up ▁to ▁ 1 . 5   k W ▁at ▁ 1 2 – 4 8 ▁vol ts ▁DC , ▁limited ▁to ▁ 3 0 ▁A . ▁▁ 2 ▁small ▁p ins , ▁for ▁C AN ▁bus ▁data ▁bus ▁high ▁and ▁low ▁lines , ▁transport ing ▁C AN open ▁with ▁C AN ▁in ▁Autom ation – 4 5 4 ▁messages . ▁▁ 2 ▁small ▁p ins , ▁for ▁auxili ary ▁DC ▁power ▁to ▁drive ▁non - power ▁components , ▁such ▁as ▁energy ▁management ▁systems ▁and ▁sens ors . ▁ ▁To ▁avoid ▁damage ▁from ▁electric ▁ar cing , ▁the ▁power ▁p ins ▁are ▁not ▁energ ised ▁until ▁communication ▁has ▁been ▁established ▁and ▁checks ▁performed . ▁ ▁For ▁b ikes ▁with ▁a ▁non - standard ▁conne ctor , ▁charg ing ▁c ables ▁are ▁used ▁which ▁contain ▁a ▁chip ▁program med ▁with ▁the ▁voltage ▁and ▁charg ing ▁parameters ▁for ▁the ▁battery ▁in ▁a ▁specific ▁manufact uer ' s ▁e - bi ke . ▁ ▁Inter change ability ▁▁ ▁The ▁main ▁intended ▁benefit ▁for ▁the ▁end - user ▁is ▁that ▁one ▁battery ▁char ger ▁can ▁be ▁used ▁for ▁batter ies ▁of ▁different ▁manufact ur ers ▁and ▁different ▁chem ist ries . ▁ ▁This
