Beschreibung
Zusammenfassung:	A method of thermally managing a battery system including enabling a sleep mode, the sleep mode causing the battery system to maintain a capability to control a temperature of a main storage battery of the battery system with a temperature control system while the machine is not in operation; monitoring a battery temperature; activating an externally powered battery management mode when connected to one or more external power sources, to heat or cool the main storage battery based on the battery temperature of the main storage battery as determined by the temperature control system, to charge the main storage battery, or to charge the auxiliary battery; and activating an internally powered thermal battery management mode when isolated from external power sources, to heat or cool the main storage battery, the internally powered battery management mode being different than the externally powered battery management mode.
