  • Publication number: 20170106760
    Abstract: Vehicles that use electric power as a motive force may use accurate measurements of battery power for numerous purposes, e.g., battery characteristics, state of charge of the battery, travel distance remaining for the vehicle and the like. A traction battery measurement should be taken when the battery is fully relaxed, i.e., the battery is neither being charged nor providing power and a time period thereafter when the battery chemistry reaches a steady state. A controller or methods may determine if the battery is relaxed and if the battery is not relaxed, delay charging or discharging of the traction battery to allow accurate battery capacity determination. The controller may control a battery charger to ensure the battery is fully relaxed before sensing battery characteristics.

  • Patent number: 9457686
    Abstract: A hybrid-electric vehicle includes a traction battery. A controller may operate the traction battery within certain state of charge and voltage limits. The controller may define a minimum operating voltage or state of charge below which no power may be requested from the traction battery. The minimum voltage and state of charge may be based on an electrical resistance of the traction battery. The voltage may also be based on a minimum power level required to crank the engine while meeting emissions standards. As the battery ages, the minimum voltage level may be adjusted such that the minimum power level is available at the minimum voltage level.

  • Publication number: 20160272080
    Abstract: A battery management system for a vehicle includes a controller programmed to apply a current pulse to reverse a current flow through a battery to reduce or remove cell polarization. After the current pulse, an open-circuit voltage is measured as the terminal voltage of the battery. The settling time for the terminal voltage to approach the open-circuit voltage is reduced after the current pulse. The magnitude of the current pulse is based on a battery state of charge, a battery temperature, and a current magnitude prior to the current pulse.

  • Publication number: 20160276843
    Abstract: A battery management system for a vehicle includes a controller programmed to charge a battery at a predetermined charge rate. The controller discharges the battery for a predetermined time in response to a terminal voltage of the battery exceeding a predetermined voltage limit that results in a reduced charge rate. After discharging for the predetermined time, the controller resumes charging at the predetermined charge rate. A current magnitude during the discharge and the predetermined time may be based on factors including the predetermined charge rate, a battery temperature, and a charge current magnitude during charging.

  • Publication number: 20160103185
    Abstract: Determination of an electric vehicle battery state-of-charge (SOC) based on measuring open circuit voltage is subject to error as the relationship changes over time. A method is provided for updating the relationship during aging. A charging current is applied to the battery cell. A favorable charging condition is detected in response to a predetermined charging current. A charging slope vector is compiled during the charging condition comprising a plurality of slope values over respective state-of-charge increments. A plurality of SOC-OCV slope vectors are determined corresponding to a plurality of stored SOC-OCV aging curves, each SOC-OCV slope vector comprising a plurality of slope values over equivalent state-of-charge increments. One of the stored SOC-OCV aging curves is selected having an SOC-OCV slope vector best fitting the charging slope vector for use in converting measured OCV values to battery cell SOC values.
