Systems and methods for charging an electric vehicle from multiple sources

An electric vehicle comprising:

• a wheel;
• an electric prime mover configured to drive the wheel;
• a battery electrically connected to the electric prime mover and configured to receive DC electrical power for charging the battery;
• an on-board charger electrically connected to the battery and configured to supply first DC electrical power for charging the battery;
• a range extender electrically connected to the battery and configured to supply second DC electrical power for charging the battery;
• a display configured to display a graphical user interface (GUI) for selecting a desired power allocation;
• and
• a controller comprising a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the controller to:
• receive context data;
• determine a power allocation for charging the battery based on the context data and the desired power allocation, wherein the power allocation comprises a portion of the first DC electrical power and a portion of the second DC electrical power;
• and
• operate the on-board charger and the range extender, based on the determined power allocation, to cause the on-board charger and the range extender to simultaneously provide power to charge the battery when the electric prime mover is not driving the wheel.

A power management controller for an electric vehicle, the power management controller comprising a processing circuit comprising a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the power management controller to:

• determine whether an external power source is connected to the electric vehicle;
• determine a current charge level of a battery of the electric vehicle;
• cause a display to display a graphical user interface (GUI) comprising (i) a slider for selecting a desired power allocation and (ii) an indication of the current charge level;
• receive context data;
• determine, based on the desired power allocation and the context data, a power allocation for charging the battery;
• and
• operate an on-board charger of the electric vehicle and a range extender of the electric vehicle, based on the determined power allocation, to cause the on-board charger and the range extender to simultaneously provide power to charge the battery.
