Research on over Current of Grounding Wire of 48V Battery Pack

【Abstract】Through the analysis process of a real vehicle case ，this paper explores the different factors causing the grounding wire over-current of 48V battery pack， and verifies and investigates each influencing factor one by one. Finally the root cause of the grounding wire over-current is identified， and a set of effective solutions are summarized to provide reference for the subsequent vehicle development
