Abstract: A thermal device comprises a first layer of a non-metallic material that is a good conductor of heat and electricity, that includes a first terminal and a second terminal, and that has a first surface and a second surface; a metallic material disposed on the first surface of the first layer; a first plastic layer disposed on the metallic material; and a second plastic layer disposed on the second surface of the first layer. The first plastic layer and the second plastic layer include a plastic material that is a good conductor of heat.

Abstract: A vehicle system is provided and includes a modular dynamically allocated capacity storage system (MODACS) and an active management module. The MODACS includes blocks of cells. The active management module is configured to: detect a first state of a first block of cells of the blocks of cells; determine whether a safety fault condition exists with the first block of cells based on the first state of the first block of cells; in response to detecting existence of the safety fault condition, isolate the first block of cells from other ones of the blocks of cells; subsequent to isolating the first block of cells, actively discharge and detect a second state of the first block of cells; and based on the second state, continue isolating the first block of cells or reconnecting the first block of cells such that the first block of cells is no longer isolated.

Abstract: A mixed chemistry battery is provided. The mixed chemistry battery includes a reference module having a first chemistry and a battery module having a second chemistry that is different that the first chemistry, the battery module is connected to the reference module in series. The mixed chemistry battery also includes a battery monitoring system configured to monitor an open circuit voltage of the reference module, an open circuit voltage of the battery module, and a current flow through the reference module and the battery module. The battery monitoring system is further configured to calculate a state-of-charge (SOC) and state-of-health (SOH) of the battery module based at least in part on a SOC of the reference module.
