PREDICTION OF BATTERY POWER REQUIREMENTS FOR ELECTRIC VEHICLES

摘要

An efficient way of predicting the power requirements of electric vehicles is proposed based on a history of vehicle power consumption, speed and acceleration as well as road information. By using this information and the operator's driving pattern, a model extracts the vehicles history of speed and acceleration, which in turn enables the prediction of the vehicle's future power requirements. That is, the power requirement prediction is achieved by combining a real-time power requirement model and the estimation of vehicle's acceleration and speed.

1. A computer-implemented method for predicting battery power requirements along a route traversed by a vehicle, comprising:
defining a power requirement model for battery cells powering the vehicle, where the power requirement model has one or more coefficients and outputs a power requirement for the battery cells as a function of velocity of the vehicle and acceleration of the vehicle; segmenting road along the route into a plurality of road segments; determining velocity and acceleration for the vehicle along a given road segment of the plurality of road segments; predicting power requirement for the battery cells of the vehicle while the vehicle is traversing the given segment, where the power requirement is predicted using the determined velocity of the vehicle along the given road segment, the determined acceleration of the vehicle along the given road segment and the power requirement model; and configuring the battery cells in accordance with the predicted power requirement while the vehicle traverses the given road segment.
