Selection of range for an electric device having a rechargeable energy storage unit

A method of selecting range for an electric device having a rechargeable energy storage unit and a controller with a processor and tangible, non-transitory memory, the method comprising:

• requesting an operator to enter a selected range for the electric device via an operator interface in communication with the controller;
• determining if the selected range is less than a predetermined maximum range, via the controller;
• if the selected range is less than the predetermined maximum range, then converting the selected range to a selected energy consumption based on a driving model of the operator, via the controller;
• determining a target voltage based at least partially on the selected energy consumption and predetermined parameters of the charging unit, via the controller;
• and
• charging the rechargeable energy storage unit to the target voltage at a predefined first charging strength, via a charging unit configured to charge the rechargeable energy storage unit at one or more charging strengths, including the predefined first charging strength.

An electric vehicle comprising:

• a rechargeable energy storage unit selectively connectable to a charging unit, the charging unit being configured to charge the rechargeable energy storage unit at one or more charging strengths, including a predefined first charging strength;
• a controller operatively connected to the rechargeable energy storage unit and including a processor and tangible, non-transitory memory on which is recorded instructions for executing a method;
• an operator interface in communication with the controller and accessible to an operator;
• a plurality of sensors configured to obtain respective data, the controller being programmed to construct a driving model of the operator based at least partially on the respective data;
• wherein execution of the instructions by the processor causes the controller to:
• request an operator to enter a selected range for the electric device on the operator interface;
• determine if the selected range is less than a predetermined maximum range;
• if the selected range is less than the predetermined maximum range, then convert the selected range to a selected energy consumption based on the driving model of the operator;
• obtain one or more modifiers for the selected energy consumption based at least partially on information selected by the operator via the operator interface, including the operator selecting between “mostly highway speed” and “mostly non-highway speed”;
• determine a target voltage based at least partially on the selected energy consumption and predetermined parameters of the charging unit;
• and
• charge the rechargeable energy storage unit to the target voltage at the predefined first charging strength, via the charging unit.
