1. A method of controlling an electric vehicle, the electric vehicle having an HVAC system configured to condition a passenger cabin of the electric vehicle, and one or more batteries configured to provide energy to the HVAC system, the method comprising: receiving a user-selected temperature setpoint for the HVAC system;determining if the electric vehicle is being charged at a charging station;if the electric vehicle is being charged, automatically modifying the temperature setpoint by increasing or decreasing the temperature setpoint of the HVAC system from the user-selected temperature setpoint; andcontrolling an output of the HVAC system to achieve the modified temperature setpoint within a passenger cabin of the electric vehicle. 2. The method of claim 1, further including: receiving a temperature of the one or more batteries;absorbing heat from the one or more batteries via a cooling system or transferring heat to the one or more batteries via a heating system; andif the electric vehicle is being charged, increasing an output of the cooling system or the heating system if the temperature of the one or more batteries is outside of an ideal operating temperature range. 3. The method of claim 1, further including; determining whether a door or a window of the electric vehicle is open; andreducing an amount of power directed to the HVAC system if a door or window is determined to be open. 4. The method of claim 1, wherein automatically modifying the temperature setpoint includes decreasing the temperature setpoint from the user-selected temperature setpoint when the HVAC system is cooling the passenger cabin, and increasing the temperature setpoint from the user-selected temperature setpoint when the HVAC system is heating the passenger cabin. 5. The method of claim 1, wherein an amount of reduction or increase of the temperature setpoint from the user-selected temperature setpoint is based on the ambient temperature outside of the electric vehicle. 6. The method of claim 1, further including setting the temperature setpoint of the HVAC system back to the user-selected temperature setpoint after charging of the electric vehicle is complete. 7. The method of claim 1, wherein receiving a user-selected temperature setpoint includes selecting a temperature from a temperature setpoint window, wherein the temperatures presented in the temperature setpoint window are determined based on an ambient temperature outside of the vehicle. 8. The method of claim 7, wherein, when the ambient temperature is between a minimum threshold temperature and a maximum threshold temperature, the temperature setpoint window presents temperatures in a range that is centered at the ambient temperature outside of the vehicle. 9. The method of claim 8, wherein: when the ambient temperature is below the minimum threshold temperature, setting a lower end of the temperatures in the temperature selection window as the minimum threshold temperature; andwhen the ambient temperature is above the maximum threshold temperature, setting an upper end of the temperatures in the temperature selection window as the maximum threshold temperature. 10. The method of claim 1, further including determining a state of charge of the one or more batteries, and reducing the power directed to the HVAC system when the state of is below a first threshold. 11. The method of claim 10, wherein the electric vehicle further includes a propulsion system configured to propel the electric vehicle, wherein the method further includes reducing the power directed to the propulsion system when the state of charge of the one or more batteries is below a second threshold that is less than the first threshold. 12. The method of claim 11, further including disabling the cooling or heating capability of the HVAC system, and only allowing the HVAC system to recirculate air through the passenger cabin when the state of charge of the one or more batteries falls below a third threshold that is less than the second threshold. 13. The method of claim 1, wherein the electric vehicle further includes an air regulator configured to adjust a ratio of fresh air to recirculated air that is directed to the passenger cabin, wherein the method further includes sending a signal to the air regulator to decrease the ratio of fresh air to recirculated air directed to the passenger cabin if a control unit determines that a door, window, or vent of the electric vehicle is open. 14. The method of claim 13, wherein sending a signal to the air regulator includes sending the signal if the control unit further determines that a difference between the ambient temperature outside of the vehicle and a temperature within the passenger cabin is greater than a fresh air temperature threshold. 15. The method of claim 13, wherein the electric vehicle further includes a cooling system configured to absorb heat from the one or more batteries or a heating system configured to transfer heat to the one or more batteries, wherein the method further includes determining if the cooling system or the heating system is operating, and decreasing the ratio of fresh air to recirculated air directed to the passenger cabin if the cooling system or the heating system is operating. 16. A control system for an electric vehicle, comprising: an HVAC system configured to condition air within a passenger cabin of the electric vehicle;one or more batteries configured to provide energy to the HVAC system; anda control unit configured to: receive a user-selected temperature setpoint for the HVAC system;determine if the electric vehicle is being charged at a charging station;if the electric vehicle is being charged, automatically modify the temperature setpoint by increasing or decreasing the temperature setpoint of the HVAC system from the user-selected setpoint, wherein an amount of the increase or decrease in temperature is based on an ambient temperature outside the vehicle;if the electric vehicle is not being charged, set the temperature setpoint of the HVAC system to the user-selected setpoint; andcontrol an output of the HVAC system to achieve the modified temperature setpoint within a passenger cabin of the electric vehicle when the vehicle is being charged. 17. The control system of claim 16, wherein the control unit is configured to allow a user to select a temperature for the user-selected temperature setpoint from a temperature setpoint window, wherein the temperatures presented in the temperature setpoint window are selected based on an ambient temperature outside of the vehicle. 18. A method of controlling an electric vehicle, the electric vehicle having an HVAC system configured to condition a passenger cabin of the electric vehicle, and one or more batteries configured to provide energy to the HVAC system, the method comprising: selecting a temperature from a temperature setpoint window as a user-selected temperature setpoint, wherein the temperatures presented in the temperature setpoint window are selected based on an ambient temperature outside of the vehicle;determining if the electric vehicle is being charged at a charging station;if the electric vehicle is being charged, automatically modifying the temperature setpoint by increasing or decreasing the temperature setpoint of the HVAC system from the user-selected temperature setpoint, wherein an amount of the increase or decrease in temperature is based on the ambient temperature;if the electric vehicle is not being charged, setting the temperature setpoint of the HVAC system to the user-selected setpoint; andcontrolling an output of the HVAC system to achieve the modified temperature setpoint within a passenger cabin of the electric vehicle when the vehicle is being charged. 19. The method of claim 18, further including; determining whether a door or a window of the electric vehicle is open; andreducing an amount of power directed to the HVAC system if a door or window is determined to be open. 20. The method of claim 18, wherein the electric vehicle further includes a propulsion system configured to propel the electric vehicle, and the method further includes: determining a state of charge of the one or more batteries;reducing the power directed to the HVAC system when the state of charge falls below a first threshold value;reducing the power directed to the propulsion system when the state of charge falls below a second threshold value that is less than the first threshold value; anddisabling a cooling or heating capability of the HVAC system when the state of charge is less than a third threshold value that is less than the second threshold value.
