Abstract: In one embodiment, a battery monitoring unit for monitoring a battery pack may include a first power MOSFET transistor with at least three pads, and a printed-circuit board with at least three copper layers. The first copper layer may have vias that connect electrical components amounted on the printed-circuit board. The second copper layer may have a first area where copper material is excluded. The first power MOSFET transistor is embedded (1) in the first area of the second copper layer where the copper material is excluded, and (2) between the first copper layer and the third copper layer. The two pads of the power MOSFET may be plated with copper. The first power MOSFET transistor may be connected to the one or more first electrical components through the at least three pads plated with copper.

Abstract: A system for managing power distribution among devices based on one or more applicable power policies. The system can receive state data, including power condition data representing power conditions associated with a plurality of devices including a first device. The system can determine, based on the power condition data, a second device to wirelessly provide power to the first device. The system can generate a power distribution command configured to cause wireless power transmission from the second device to the first device and send the power distribution command to at least one of the first device or the second device to initiate wireless power transmission from the second device to the first device.
