Abstract: A heat management safety enhanced vehicle battery pack based on nested lithium ion batteries includes an insulating housing. K insulating positioning and connecting plates are arranged in the insulating housing along a vertical direction. The positioning and connecting plate on each layer includes the batteries in M rows and N columns to form battery pack units. All the battery pack units perform output alone or perform output after being connected in series or in parallel to form a battery pack. Each battery includes a metal shell and a cell filled in the shell. The shell includes an inner cylinder and an outer cylinder. The inner cylinder is located in a through hole in the center of the outer cylinder. A gap is formed between a side wall of the inner cylinder and a secondary outer wall of the outer cylinder. The cell includes an outer cell and an inner cell.

Abstract: The present disclosure provides a method of managing thermal loads in the powertrain of an electric vehicle and controlling various electronic components of a powertrain thermal management system. The method may include heating a coolant of a powertrain coolant loop utilizing waste heat from a liquid-cooled powertrain component (e.g., an electric motor, a DC-DC converter, etc.), measuring a coolant temperature, and utilizing combined feedforward and feedback control methods for different components (pump(s), radiator fan(s), valve(s)) of the powertrain thermal management system.

Abstract: Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A method comprises positioning a swappable battery module on an external charger comprising charger fluidic ports and sliding the swappable battery module to the charger fluidic ports until these charger's ports are fluidically coupled with the module's fluidic ports. Specifically, the external charger comprises an enclosure and a module support rail slidably coupling the swappable battery module and the enclosure. The module support rail comprises a rail base, a first slider, a second slider, and a lever-based unit, interconnecting the rail base and both sliders. The rail base is fixed to the enclosure, while the second slider is detachably coupled to the module. The two sliders move at different speeds or at the same speed relative to the charger base depending on proximity of the first end plate to the charger base.

Abstract: A battery module compression system includes a battery module having a first end wall spaced apart from a second end wall. Battery cells are disposed between the first and second end walls. A fluid path is between the plurality of battery cells and the walls. An inlet valve is in fluid communication with an inlet module pump communicating dielectric fluid into the battery module into the fluid path between the battery cells and the walls. A pressure sensor generates a pressure signal indicative of the pressure within the battery module. A temperature sensor generates a temperature signal indicative of the temperature within the battery module. A controller is coupled to the inlet module pump, the inlet valve and an outlet valve to independently control a flow rate into the battery module and the pressure within the battery module based on the temperature signal, and the pressure signal.
