Abstract: A power supply system that includes a traction battery, and a secondary battery that includes one or more hybrid modules having one or more low temperature chemistries. The power supply system also has one or more temperature sensors, and a switching device that connects or disconnects the secondary battery or the traction battery from a high-voltage DC (Direct Current) bus of an electric vehicle based on measurements of the one or more temperature sensors.

Abstract: A highly efficient arrangement for a battery pack including a first battery and a second battery inductively coupled together to transfer energy from the second battery to the first battery includes a triple-active bridge DC-DC converter.

Abstract: Actively venting by measuring venting parameters of the cell, computing, using the venting parameters, a pre-venting state of the cell, and preemptively triggering, responsive to computing that the pre-venting state has reached a threshold pre-venting state, an opening of a vent of the cell to release vent-gas. The preemptive triggering is performed by activating a cell vent opening device to open the vent.

Abstract: An anode-free cell including a cathode, an anode current collector and a separator disposed between the cathode and the anode current collector. It also includes a short-circuit limitation configuration configured by (i) the anode current collector and/or the cathode current collector being a polymer current collector, and/or (ii) the cathode dimension being the same as the anode current collector and/or of the separator dimension, or the dimension of the cathode being larger than the dimension of the anode current collector. The dimension is measured in the X-axis and/or Y-axis. Another cell includes a cathode and an anode and the short-circuit limitation configuration is configured by (i) the anode current collector being a polymer anode current collector and the cathode current collector being a polymer cathode current collector; and (ii) the dimension of the anode active material layer and of the cathode active material layer being the same.

Abstract: A busbar that includes a low profile, flexible body made of aluminum layers stacked together on their longitudinal surfaces. The aluminum layers are laser welded together and are designed to have an offset at a middle portion such that the middle portion has a raised profile. A method of laser welding the aluminum layers is also disclosed.

Abstract: A power supply system that utilizes a hybrid architecture to enable low cycle-life, high energy density chemistries to be used in rechargeable batteries to extend the range of a traction battery.

Abstract: An anode-free cell that includes a cathode and a separator-collector-separator structure. The separator-collector-separator structure includes a perforated anode current collector, and a polymer layer contiguously disposed on both surfaces of the perforated anode current collector through perforations in the perforated anode current collector. The polymer layer is a binder.

Abstract: A cap assembly that includes a cap plate having an upper surface and a lower surface, the cap plate being formed to seal an opening of a cell case and to have a terminal hole, an electrode terminal inserted into the terminal hole, and an insulator positioned between the cap plate and the electrode terminal and inserted into the terminal hole, with the insulator making contact with the lower surface of the cap plate. The insulator has a first unibody structure and insulates the electrode terminal from the cap plate.
