  • Core-shell particles based on red lead for lead-acid batteries
    Patent number: 12015144
    Abstract: Core-shell particles may be based on red lead coated with pyrogenically produced titanium dioxide and/or a pyrogenically produced aluminum oxide, and a process may prepare such core-shell particles which may be used in lead-acid batteries. The red lead may include PbO2 in a range of from 25 to 32 wt. %.
    Type: Grant
    Filed: March 23, 2022
    Date of Patent: June 18, 2024
    Assignee: Evonik Operations GmbH
    Inventors: Daniel Esken, Michael Glagla, Rainer Bussar, Micha Kirchgessner, Ian Klein

  • Method for determining a state of charge and remaining operation life of a battery
    Patent number: 10031185
    Abstract: Determining a state of charge (SOC) of a rechargeable battery includes using a first process to determine a first value for the SOC of the battery and using a second process to determine a second value for the SOC of the battery and deriving the SOC as a weighted average of the first value for the SOC and the second value for the SOC. During a charging cycle of the battery an input charge of the battery is determined from an input current flowing into the battery and a charging time. During a discharging cycle an output charge of the battery is determined from an output current flowing out of the battery, a discharging time and an actual capacity of the battery is the sum of the input charge over charging cycles minus the sum of the output charge over discharging cycles.
