  • Apparatus and method for determining state of change (SOC) and state of health (SOH) of electrical cells
    Patent number: 10132781
    Abstract: A method, an apparatus and a system for interrogating a battery in order to determine one or more of: (i) its state of charge (SOC), (ii) its state of health (SOH), (iii) physical state of one or more internal components or parts, which utilizes at least one sound source for transmitting a signal (e.g., a sound wave or sound pulse through or across the battery, and at least one sound receiver for receiving a signal from the battery, which received signal is representative of the physical state of the battery being interrogated. The interrogation method is noninvasive, namely does not require the depletion of a portion of the charge of the battery being tested or settlement or the destruction of the battery in order to evaluate one or more of (i), (ii) and (iii).

  • Determining electrical current using at least two sensors at a known distance from each other
    Patent number: 8125214
    Abstract: The invention relates to methods and devices for accurately monitoring the electrical current in electrolytic cells used to produce metals, including but not limited to aluminum, or other chemical substances. A plurality of sensors are placed at some distance from the conductor, with at least two sensors at a known distance from each other. Measurements from the plurality of sensors are used to calculate the electrical current.
