Vehicle battery system including response to energy expenditure event

A vehicle comprising:

• a propulsion system having at least one electric motor powered by a vehicle energy storage component;
• a plurality of auxiliary systems configured to receive operational power from one of the vehicle energy storage component and a vehicle power system able to receive power from the vehicle energy storage component;
• a charger configured to interface with an external power source and provide power to the vehicle energy storage component;
• and
• a controller configured to control power distribution through the vehicle, the controller including a memory storing instructions for causing the vehicle to:
• direct electric energy from the external power source to a vehicle energy storage component until the vehicle energy storage component is charged to a threshold state of charge percentage,
• monitor, using the controller, a data source external to the vehicle for an occurrence of an energy expenditure event external to the vehicle
• respond to the energy expenditure event by charging a remainder of the vehicle energy storage component, and
• and monitor, using the controller, whether the energy expenditure event is still present when the remainder of the vehicle energy storage component has been fully charged and includes expending energy from the vehicle energy storage component while simultaneously charging the vehicle energy storage component such that 0 net current passes through the vehicle energy storage component by simultaneously operating a heating and a cooling portion of the vehicle HVAC system.
