Electric mining vehicle, charge controller, and related process
First Claim
1. A charge controller for an electric mining vehicle, the charge controller configured to determine an amount of charge to be provided to a battery of the electric mining vehicle for an upcoming trip based on regenerative braking power generation and load indication the load indication indicating an amount of load hauled by the electric mining vehicle during a previous trip or to be hauled by the electric mining vehicle during the upcoming trip, the charge controller further configured to command a battery charger to charge the battery up to the determined amount of charge and to stop charging the battery once the determined amount of charge has been reached.

Abstract
A charge controller for an electric mining vehicle is configured to determine an amount of charge to be provided to a battery of the electric mining vehicle for an upcoming trip based on regenerative braking power generation and load indication measured during a previous trip. The charge controller is further configured to command a battery charger to charge the battery up to the determined amount of charge and to stop charging the battery once the determined amount of charge has been reached.
