Abstract
A battery connector system includes a tray assembly configured to be mounted to a battery module made from a plurality of battery cells. The tray assembly has a tray and a plurality of busbars held by the tray. The tray has a tray connector defining a mating interface being configured to mate with an electrical connector. The electrical connector may be either a wire harness connector or a circuit board connector. The busbars are coupled to the tray and have plates being configured to be electrically connected to corresponding cell tabs of the battery cells. The busbars have fuse terminals positioned in the tray connector. A plurality of fuses are coupled to the fuse terminals. The fuses may be serviceable fuses or resettable fuses. The fuses are connected between the plates of the busbars and the electrical connector.
