Abstract: A fully integrated circuit configuration that can be utilized to prevent abnormal discharge or overcharge in ultra-portable electronic systems is described. This battery protection integrated circuit can be enhanced by the addition of traditional battery protection schemes such as current limiting, overcurrent clamping, under voltage lock out and over voltage protection. This battery protection scheme utilizes a high side switch approach utilizing an ultra-low leakage PMOS power switch rather than the traditional low side NMOS switching.

Abstract: An autonomous underwater vehicle includes a vehicle body controlled by a processor. An anchor joined to a tether is disposed in the vehicle. The vehicle has control surfaces for maneuvering, a propulsion unit, and a turbine. The propulsion unit and turbine generate thrust to propel the vehicle. A power source provides power to the vehicle. The turbine is further joined to a generator. When the processor detects that the power source is below a threshold value, the propulsion unit is stopped, the anchor is deployed, and the control surfaces are operated to move the vehicle in a predetermined trajectory through a fluid stream of the environment restrained by the tether. The fluid stream causes rotation of the turbine and generator to recharge the power source.

Abstract: Methods and systems for protection/disconnect of airborne high-power/energy high-voltage modular multi-string battery packs (such as battery packs for airborne electric propulsion systems). The methods and systems are based on a dissimilar/redundant distributed battery pack protection architecture and use a smart mid-point battery disconnect in conjunction with centralized battery management system. The resulting battery disconnect/protection system is configured to detect bus faults, load faults and string faults and then take appropriate action to isolate the detected fault. For example, in response to a short circuit in one battery string, the faulty battery string may be disconnected from the positive and negative busbars while the remaining battery strings continue to provide power.
