Preconditioner system for a battery of a vehicle and method

A method of preconditioning a battery for a vehicle, the method comprising:

• detecting a state of charge of the battery;
• determining the state of charge is below a first threshold;
• prompting a user to connect the battery to a charger;
• detecting a temperature of the battery;
• determining the temperature of the battery is outside a targeted battery temperature range;
• determining a charging capacity of the charger is below a second threshold at the temperature;
• detecting a condition for a cabin defroster being deactivated;
• deactivating the cabin defroster in response to determining that the condition for the cabin defroster being deactivated is met;
• activating a preconditioner to change the temperature of the battery toward the targeted battery temperature range;
• detecting a clarity of a window and determining whether the clarity of the window exceeds a clarity threshold;
• and
• prompting a user to:
• increase an air flow temperature;
• activate an air conditioner;
• activate an outside air intake;
• increase air flow;
• and
• direct a side window toward an ajar position in response to the clarity being less than the clarity threshold.

A method of preconditioning a battery for an electric vehicle, the method comprising:

• detecting a state of charge of the battery;
• determining the state of charge of the battery is below a threshold percentage;
• prompting a user to connect the battery to a charger;
• detecting a temperature of the battery in response to the user affirming to connect the battery to the charger;
• determining the temperature of the battery is outside a targeted battery temperature range;
• observing a charging capacity of the charger;
• determining the charging capacity of the charger is below a second threshold at the temperature of the battery;
• determining whether a measured duration a cabin defroster has been active exceeds a target duration the cabin defroster activates to defrost and deice a window;
• determining whether a measured clarity exceeds a target clarity of the window;
• prompting a user that preconditioning is recommended and to deactivate the cabin defroster in response to the measured duration exceeding the target duration and the measured clarity exceeding the target clarity;
• deactivating the cabin defroster in response to the user providing an input to deactivate the cabin defroster;
• and
• activating a preconditioner to change the temperature of the battery toward the targeted battery temperature range.
