  • Single sided reusable battery indicator
    Patent number: 10818979
    Abstract: A reusable battery indicator includes a voltage sensor, a communication circuit communicatively connected to the voltage sensor, an antenna operatively coupled to the communication circuit, and a connection mechanism having a first connector and a retainer. The first connector and the retainer are electrically connected to the voltage sensor, and the first connector is adapted to be removably connected to a first battery terminal, thereby providing an electrical connection between the voltage sensor and the first battery terminal. The retainer is adapted to removably secure the voltage sensor to a can of a battery, thereby providing an electrical connection between the voltage sensor and the can of the battery. An electrical circuit is completed between the voltage sensor and the first battery terminal and between the voltage sensor and the can.

  • Batteries having vents
    Patent number: 10804515
    Abstract: Batteries having vents are disclosed. An example battery includes a housing, including: a first terminal and a second terminal. The first terminal includes a cover. The cover includes at least one line of weakness therein. The line of weakness is structured to form an opening when a threshold pressure is satisfied within the housing to enable gas to vent from the housing through the opening. A filter is positioned within the housing and adjacent the cover. The filter has an aperture structured to enable the gas to vent from the housing and to deter solid material housed within the housing from exiting the opening when the threshold pressure is satisfied.

    Patent number: 10698032
    Abstract: A method of remote sensing a charge includes charging or discharging a first capacitor of a first RC circuit and a second capacitor of a second RC circuit to a predetermined threshold voltage using a power source. When each of the capacitors reach the predetermined threshold voltage, a response signal is provided from a communications module to a handheld computing device comprising a reader system. An amount of time between the response signals is determined. The amount of time is indicative of charge information.

  • Positive battery terminal antenna ground plane
    Patent number: 10483634
    Abstract: A positive terminal of a battery may act as an antenna ground plane for communicating battery status information. The positive terminal of the battery may include a first electrically conductive external surface with a first surface area. The negative terminal of the battery may include a second electrically conductive external surface with a second surface area less than the first surface area. An antenna impedance matching circuit may electrically connect to a communication circuit, an antenna, and the positive terminal of the battery. Thus the positive terminal of the battery may act as a ground plane for the antenna.
