A holding apparatus (15) for current and signal conductors of a traction battery of a motor vehicle has a plate-like base body with longitudinal sides (16), transverse ends (17) and a top (18) and bottom (19) extending between the longitudinal sides (16) and transverse ends (17). Elements (20) are arranged on the top (18) and the bottom (19) for guiding and fixing current conductors (12) of the traction battery, and elements (21) are arranged on the other of the top (18) and the bottom (19) for guiding and fixing at least one signal conductor (14) of the traction battery. The base body provides EMC shielding of the signal conductor (14) from the current conductors (12). The plate-like base body has on the opposite longitudinal sides (16) and/or on the opposite transverse sides (17) sections (22) for securing and grounding the holding apparatus on a frame of the motor vehicle.

A battery system with a passive thermal management system is formed from a plurality of battery cells arranged on a printed circuit board assembly. In some cases, the printed circuit board assembly may include a flexible printed circuit board that is folded along an axis forming an upper and lower portion of the printed circuit board assembly. The thermal management system may include fire-blocking foam members individually attached to each battery cell. The battery cells may be arranged in a grid-like pattern to allow for a spacing arrangement between the battery cells to keep a failing battery cell from negatively affecting an adjacent battery cell. In addition, the flexible printed circuit card may include a fuse for each battery cell to shut off any current flow to a faulty battery cell if it begins to fail causing current flow to exceed beyond a predetermined current limit. The battery system may be a conformal wearable battery.

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.
