Abstract: Aspects of this disclosure relate to a system for energy storage with integrated heating. The system can include a battery cell. The system can include a battery management board assembly coupled to the battery cell. The battery management board assembly can include a printed circuit board, an integrated circuit coupled to the printed circuit board and configured to monitor the battery cell, and an integrated heating element integrated with the printed circuit board and configured to heat the battery cell.

Abstract: An ultrasonic sensor assembly is placed against an inside surface of a panel for sensing objects on an opposite side of the panel and includes an ultrasonic sensor, a preload structure, a coupling element, and a damping material. The preload structure applies a preload on the ultrasonic sensor toward the inside surface of the panel. The coupling element interfaces between the ultrasonic sensor and the inside surface of the panel. The damping material is placed against the inside surface but not where the coupling element interfaces between the ultrasonic sensor and the inside surface. The coupling element may include a matrix material that is reinforced with a filler.
