A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.

An estimation device configured to estimate a charge rate of a battery includes a voltage sensor configured to detect a voltage of the battery, a temperature sensor configured to detect a temperature of the battery, and a processing circuit. The processing circuit is connected to the voltage sensor and the temperature sensor and is configured to execute, while a vehicle is parked, an estimation process of estimating the charge rate of the battery based on a detection voltage and a detection temperature. The detection voltage is detected by the voltage sensor. The detection temperature is detected by the temperature sensor.
