Abstract: A flexible sheet having enhanced thermal conductivity, electrical isolation and bonding strength includes a first layer of polyethylene terephthalate having opposed first and second sides and an electrical isolation of at least 500 ohms at 2.0 kV DC, and a second layer of heat-activated adhesive attached to and covering the first side. The heat-activated adhesive has a bonding strength of greater than 50 psi, and the first and second layers together have a thermal conductivity of at least 0.7 W/mK. A thermal cooling structure for use with high-voltage battery applications includes the first layer of polyethylene terephthalate, the second layer of heat-activated adhesive, a third layer of thermal interface material attached to and covering the second side of the first layer, and a metallic cooling plate attached to the second layer.

Abstract: A vehicle includes a system operating a method of controlling a temperature at a battery cell of the vehicle. The system includes the battery cell, a temperature sensor and a processor. The battery cell has a tab for flow of current to and from the battery cell. The temperature sensor is configured to measure a cell temperature of the battery cell at a location away from the tab. The processor is configured to predict a tab temperature from the cell temperature, and control a power supplied to a load from the battery cell based on the tab temperature.

Abstract: A rechargeable energy storage system and a method of manufacturing includes a battery pack having a battery cell module assembly with an interconnect board disposed between and physically connecting the battery cells with the cell monitoring unit, and a module cover at least partially enclosing the battery cells, the cell monitoring unit, and the interconnect board. The battery pack has relatively high and relatively low loss regions for radio frequency signal communication. A radio frequency manager is wirelessly connectable to the cell monitoring unit by radio frequency signal communication. A signal directing component is operable for transmitting and/or receiving a radio frequency signal between the cell monitoring unit and the radio frequency manager, is configured to direct the radio frequency signal to the relatively low loss region, and is integrated in one of the module cover, the interconnect board, or the radio frequency manager.
