Abstract: An advanced mobile energy storage device includes an energy storage component for the storage of electrical energy and characterized by a state of charge representative of an amount of energy stored within the energy component and by an energy storage rate into and out of the energy storage component. At least one power input transfers electrical energy into the device for storage in the energy storage component. At least one power output transfers electrical energy out of the device from the energy storage component. A processor determines, for indication to a user, an estimate of time until the state of charge at least reaches one or more particular levels, the estimate determined at least from the state of charge in conjunction with the energy storage rate. The device can network with an external computing device and can generate solar adjustment information.

Abstract: A solar energy-storage cooler includes an insulated housing and a lid movable between a closed position, sealing the opening, and an open position for access to an interior of the housing. A solar power source generates electrical energy for an energy storage component in the housing which is part of an energy storage device. The housing can include a separate secure compartment. A compartment door can close the secure compartment door for locking by a lock mechanism to limit unauthorized access to the secure compartment. The lid and compartment door can share a common hinge. A motion sensor can characterize motion of the housing. An estimate of time can be determined as predictive of a state of charge of the energy storage device. Temperature indications are provided responsive to a temperature sensor.
