A manual service disconnect for a battery system includes a disconnect header having a housing defining a receptacle, a high current terminal connector within the receptacle, a high voltage interlock (HVIL) connector within the receptacle and a control device terminal connector within the receptacle. A disconnect plug is removably coupled to the disconnect header. The disconnect plug has a high current fuse electrically connected to the high current terminal connector and a HVIL shunt terminal electrically connected to the HVIL connector. A current power control device is received in the receptacle and is electrically connected to the control device terminal connector. The current power control device is exposed for servicing when the disconnect plug is removed from the disconnect header and the current power control device is inaccessible when the disconnect plug is coupled to the disconnect header.

Manual service disconnects for battery systems

A service disconnect assembly includes a receiver assembly having a fuse receptacle that is configured to receive a fuse therein. The service disconnect assembly includes a lockout device having a latch. The latch is actuatable between a latched position and an unlatched position. The latch cooperates with the receiver assembly in the latched position such that the lockout device cannot be removed from the receiver assembly. The latch is configured to be locked in the latched position.

Service disconnect assembly

A service disconnect assembly for a battery assembly includes a receiver configured to hold terminals of a power circuit of the battery assembly and a service disconnect removably coupled to the receiver. The service disconnect has a hub rotatably coupled to the receiver that holds a terminal interconnect configured to electrically connect the terminals together. The service disconnect is removable from the receiver to disconnect the terminals from one another. Rotating the hub in a first direction drives the terminal interconnect into engagement with the terminals and rotating the hub in a second direction opposite to the first direction releases the terminal interconnect from the terminals.
