Abstract
A vehicle includes a rechargeable energy storage device, such as a battery. A recharging system is operatively connected to the energy storage device and configured to selectively charge the energy storage device by transmitting energy thereto. A regenerative braking system is operatively connected to the energy storage device to selectively transmit energy thereto. A controller is operatively connected to the recharging system and configured to control the recharging system. The controller is configured to determine an amount of the vehicle'"'"'s gravitational potential energy that is recoverable by the regenerative braking system over a predicted route, and to control the recharging system such that the amount of energy transferred from the recharging system to the energy storage device is based on the amount of the vehicle'"'"'s gravitational potential energy that is recoverable by the regenerative braking system over the predicted route.
