1. A method of providing an intelligent charge limit for a battery in a vehicle, comprising the steps of:
utilizing at least one of horizon map data, a road grade sensor, wheel torque and vehicle speed, said horizon map data includes data of downhill segments in a travel route, said road grade sensor provides a slope of the travel route either positive or negative;
calculating dynamically a percentage of a maximum charge limit to create a dynamic maximum charge limit for a battery based on at least one of said horizon map data, said road grade sensor, wheel torque and vehicle speed;
inputting an operator maximum charge limit entered by a user;
offsetting said operator maximum charge limit with said dynamic maximum charge limit to define a maximum charge limit for charging the battery.
