  • Patent number: 11133697
    Abstract: The wireless portable electronic charger recharges each of the one or more personal data devices. The wireless portable electronic charger: a) draws AC electrical energy from a national electric grid; and, b) wirelessly broadcasts the received AC electrical energy to the one or more personal data devices. The wireless portable electronic charger comprises an energy broadcast circuit and one or more induction circuits. The energy broadcast circuit broadcasts the received AC electrical energy to the one or more induction circuits. Each induction circuit selected from the one or more induction circuits: a) receives the AC electrical energy broadcast from the energy broadcast circuit; b) converts the received AC electrical energy into DC electrical energy suitable for use by a personal data device associated with the selected induction circuit; and, c) transmits the DC electrical energy to the battery of the personal data device.

  • Patent number: 11131713
    Abstract: A computer-implemented method predicting a life span of a battery storage unit by employing a deep neural network is presented. The method includes collecting energy consumption data from one or more electricity meters installed in a structure, analyzing, via a data processing component, the energy consumption data, removing one or more features extracted from the energy consumption data via a feature engineering component, partitioning the energy consumption data via a data partitioning component, and predicting battery capacity of the battery storage unit via a neural network component sequentially executing three machine learning techniques.

  • Patent number: 11081899
    Abstract: A battery system includes a battery circuit group in which a plurality of battery circuits, each including a plurality of battery units including a battery and a switching unit connected in series, are connected in parallel, and a control unit that controls the switching unit. The switching unit switches a state of the battery unit between a first state, in which the battery is connected between a positive electrode end and a negative electrode end of the battery unit, and a second state, in which the positive electrode end and the negative electrode end are connected without the battery. When discharging, the control unit controls the switching unit such that the state of the battery unit including the battery determined to be not fully discharged becomes the first state, and the state of the battery unit including the battery determined to be fully discharged becomes the second state.

  • Patent number: 11075425
    Abstract: A battery pack is provided with an improved charger interface through the use a contact carrier assembly. The non-conductive contact carrier aligns and retains a plurality of charger contacts. The carrier aligns a first portion of each charger contact along a back surface of the battery pack housing and further facilitates alignment of another portion of each charger contact within bottom apertures of the housing thereby allowing each contact to extend across perpendicular back and bottom surfaces of the housing with improved ruggedness. Improved sealing is also provided by sealing the back of the carrier.

  • Patent number: 11075530
    Abstract: A collection, charging and distribution machine collects, charges and distributes portable electrical energy storage devices (e.g., batteries, super- or ultracapacitors). To charge, the machine employs electrical current from an external source, such as the electrical grid or an electrical service of an installation location. The machine determines a first number of devices to be rapidly charged, employing charge from a second number of devices identified to sacrifice charge. Thus, some devices may be concurrently charged via current from the electrical service and current from other devices, to achieve rapid charging of some subset of devices. The devices that sacrifice charge may later be charged. Such may ensure availability of devices for end users.

  • Patent number: 11043827
    Abstract: A device, system, and method enhances battery performance on a user equipment. The user equipment includes a rechargeable battery, a charging circuit, and a processor. The charging circuit controls a recharging operation for the rechargeable battery. The processor determines an activity condition and a charge condition, the activity condition based on a foreground activity running on the user equipment, the charge condition based on a charge capacity of the rechargeable battery being above a capacity threshold. The processor selects a first charging rate at which the charging circuit recharges the rechargeable battery when at least one of the activity condition and the charge condition is absent. The processor selects a second charging rate when the activity condition and the charge condition are present, the second charging rate being less than the first charging rate.
