An active sacrificial protection device includes a third contactor and a first fuse. The active sacrificial protection device is connected to a positive or negative terminal of the battery system. A current sensor is configured to sense a measured load current flowing through one of the first contactor and the second contactor. A battery management module is configured to selectively close the third contactor to reduce current flowing through one of the first contactor or the second contactor and selectively open the one of the first contactor or the second contactor after closing the third contactor.

A temperature-sensitive battery connector is disclosed. The connector can include a connector body and at least one conductor mounted to the connector body and configured to convey a current signal used to measure voltage from a battery pack or battery cell to a battery management system (BMS). The connector can include a thermal switching device mounted to the connector body and thermally coupled to a terminal of a battery pack or a battery cell. The thermal switching device can be configured to provide an overtemperature signal to the BMS by changing or interrupting a current conducted by at least one conductor when a temperature of the battery pack or battery cell exceeds a threshold temperature.

An attachment assembly joining a fuse box and battery tray includes a fuse box having a mounting structure having a fuse bottom surface including a retainer structure joined therewith. The retainer structure includes a cylindrical boss having an attachment wall disposed within the cylindrical boss. A cutout is formed in the cylindrical boss. A battery tray includes a tray bottom surface. The tray bottom surface includes a mating structure including a pair of spaced annular walls extending therefrom defining a gap. Each of the annular walls includes notches formed therein. A J-nut is positioned in the cut out of the cylindrical boss and over an edge of the attachment wall retaining the J-nut on the attachment wall. The cylindrical boss is disposed between the pair of spaced annular walls in the gap and the cutout is aligned with the notches. The J-nut is positioned in the cut out and the notches rotatively aligning the battery tray relative to the fuse box.

A fuse array for use in a vehicle electrical system having more than one battery, such as in a start-stop vehicle that automatically shuts off an engine when the vehicle comes to a stop and automatically restarts the engine when a driver starts driving again. The fuse array includes first and second discrete circuits, where the discrete circuits include their own internal bus bars and are electrically isolated from one another, even though they are part of the same fuse array. This enables the fuse array to independently provide battery power to different downstream electrical components, such as a power distribution device and various high amperage components, while still utilizing a single compact assembly.

A fuse unit includes: a fusible link which is connected to a battery terminal and of which a fuse is fused when overcurrent flows therein; and a holding mechanism including a base portion that is interposed between a post-standing surface and the battery terminal in a state in which the battery terminal is fastened to a battery post provided on the post-standing surface of a battery housing, and a holding portion that is connected to the base portion and holds the fusible link on the post-standing surface. Accordingly, a load acting on the battery post can be suppressed.

A circuit protection assembly (CPA) is disposed between a source of power and a circuit to be protected. The CPA comprises a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block. A post having a first end is disposed within the recess cavity and a body portion extends through the bore. The body portion configured to receive a terminal and the second end configured to receive a securing mechanism. A fuse having a centrally disposed aperture is configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected. An insulator disposed on the terminal and disposed beneath the securing mechanism. The insulator configured to isolate the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque.

The present disclosure provides a multifunctional high-voltage connector and a battery product, the multifunctional high-voltage connector comprises: an upper cover; a pedestal; a conductive connection structure; two mating terminals; and a harness assembly. The conductive connection structure is used to make the two mating terminals be connected in series, and the harness assembly is directly connected to one of the mating terminals. When the upper cover and the pedestal are assembled, the conductive connection structure is simultaneously in contact with the two mating terminals, thereby turning on the high-voltage circuit. When the battery product requires maintenance, the upper cover is directly detached from the base, thereby turning off the high-voltage circuit. The battery product can be electrically connected to an external device via the harness assembly. The multifunctional high-voltage connector integrates both a switch function and a high-voltage connection function, therefore the connection resistance is greatly reduced.

Provided is a fusible link unit in which a case includes case-side locking portions to be locked in a fusible link so as to affix the fusible link, the fusible link includes fusible link-side locking portions locked in the case-side locking portions, the fusible link-side locking portion on one side in a longitudinal direction is provided closer to a connected position of a bus bar than the fusible link-side locking portion on the other side in the longitudinal direction, and a gap size between the fusible link-side locking portion on the one side and the case-side locking portion in a vertical direction is made greater than a gap size between the fusible link-side locking portion on the other side and the case-side locking portion in the vertical direction.

A fuse unit includes a fusible link, a holding mechanism, and a locking mechanism. The fusible link is connected to a battery terminal and includes a fusible element that melts when an overcurrent flows through the fusible link. The holding mechanism includes a base portion disposed between a post standing surface of a battery housing and the battery terminal in a state where the battery terminal is fastened to a battery post provided on the post standing surface, and a holding portion that is formed next to the base portion and that holds the fusible link above the post standing surface. The locking mechanism locks the holding mechanism onto the post standing surface. With this configuration, the fuse unit can suppress a load acting on the battery post.
