1. A system for managing a battery within a vehicle, comprising:

  • a cooling subsystem including a fluid;

    a cabin circulation subsystem coupled to the cooling subsystem to utilize the fluid for cabin cooling;

    a battery circulation subsystem coupled to the cooling subsystem to utilize the fluid for battery cooling;

    a temperature sensor that monitors a battery temperature corresponding to the battery; and

    a processor to regulate operation of the cabin circulation subsystem and the battery circulation subsystem, wherein said processor estimates a remaining operational time before the battery reaches a state of depletion, wherein said processor estimates a time before said battery temperature reaches a threshold battery temperature, and wherein said processor prevents operation of said battery circulation subsystem if said remaining operational time is less than said time before said battery temperature reaches said threshold battery temperature.
