Abstract: Battery management techniques for a vehicle include a set of sensors configured to measure a set of parameters of a battery of the vehicle and a controller configured to control recharging of the battery to a first target state of charge (SOC) corresponding to optimized battery life when a mileage of the vehicle is less than a threshold mileage corresponding to an expected transport period of the vehicle, wherein controlling the recharging of the battery to the first target SOC prevents battery malfunctions and thereby reduces vehicle warranty costs for an original equipment manufacturer (OEM) of the vehicle, and control recharging of the battery to a second target SOC determined by a cost-based optimization technique when the mileage of the vehicle reaches the threshold mileage.

Abstract: Charging control techniques for a vehicle including an engine that drives an alternator configured to charge a battery of the vehicle comprise modeling a fuel consumption of the alternator for each load level across a range of alternator loads using an engine torque model and a set of operating parameters of the engine, determining an energy output from the alternator for each load level across the range of alternator loads, calculating a cost-to-charge metric based on the modeled alternator fuel consumption and the determined alternator energy output for each duty cycle across a range of duty cycles of the alternator, determining an optimal cost-to-charge from the calculated cost-to-charge metrics, determining a target cost-to-charge metric based on a state of charge of the battery, and operating the alternator accordingly at an optimal duty cycle based on the metrics and current engine operating conditions.
