  • Publication number: 20170267116
    Abstract: A system for optimizing life of a battery pack in a plug-in vehicle includes sensors for measuring battery performance data, including an open-circuit voltage, charging current, and/or temperature of the battery pack, a GPS receiver, a user interface, and a controller. The controller executes a method to monitor degradation of the battery pack using the performance data, and determines driving and charging histories for an operator of the vehicle using the measured battery performance data and a position signal from the GPS receiver. The histories identify the days, hours, and locations at which the operator has driven the vehicle and charged the battery pack. The controller identifies a state of charge data bin missing performance data or containing old performance data. The controller then controls a charging operation of the battery pack via a charging control signal, and records the measured battery performance data for the identified SOC data bin.

The chamfer may be formed at an abutment edge disposed between the tooth top and a respective meshing surface via a brushing process directly following the machining of the teeth.
