This disclosure describes methods and apparatus for indicating battery cell status on a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide methods for indicating battery cell status on the exposed exterior of a battery assembly pack both when the battery is in use and when the battery is not in use during mechanical ventilation. Embodiments utilize power from the ventilator as well as power from the battery pack itself to light the indicators during periods of battery use and non-use, respectively. Embodiments described herein further seek to provide an apparatus indicating battery cell status on the exposed exterior of the battery pack assembly during mechanical ventilation. Embodiments described herein further seek to provide an apparatus for a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide a system for a ventilation system with an inserted battery pack assembly.

1. A method for indicating battery cell status on the exterior of a battery pack assembly inserted in a ventilator for use during mechanical ventilation, the method comprising: receiving information about the battery cell status from the battery pack;providing power to one or more indicators located on the battery pack assembly's exposed exterior, wherein power is provided: by electronics of the battery pack assembly if the battery pack assembly is in use by the ventilator;by electronics of the ventilator if the battery pack assembly is not in use by the ventilator; andlighting the one or more indicators based on the battery cell status, the indicators located on an exposed exterior of the battery pack assembly so that a user can view the indicators without removing the battery pack assembly from the ventilator. 2. The method of claim 1, wherein information about the battery cell status is determined by the electronics of the battery pack. 3. The method of claim 2, wherein power is continuously provided to the one or more indicators by the electronics of the battery pack assembly when the battery pack assembly is in use by the ventilator. 4. The method of claim 2, wherein information about the battery cell status is sent from the electronics of the battery pack to the electronics of the ventilator when the battery pack is not in use by the ventilator. 5. The method of claim 4, wherein power is continuously provided to the one or more indicators by the electronics of the ventilator when the battery is not in use by the ventilator. 6. The method of claim 1, wherein the battery cell status comprises information about at least one of: state of charge, battery current, voltage, assembly number, revision, number of discharges, number of charges, date, in-use status, and fault. 7. The method of claim 1, wherein the information about fault includes information about over-charge, temperature, over-discharge, and voltage current charge. 8. The method of claim 1, wherein the one or more indicators are at least one of: a LED bar indicator and an alpha-numeric display. 9. The method of claim 1, wherein the battery pack assembly is hot swappable. 10. The method of claim 1, wherein the one or more indicators display battery cell status of battery charge, in-use status, and fault. 11. The method of claim 10, wherein lighting the one or more indicators further comprises lighting the indicators displaying battery charge to correspond with the percentage of charge held by the battery, each indicator being lit when the battery reaches a certain percentage of charge. 12. A battery pack assembly for indicating battery cell status on the exterior of the battery pack assembly used during mechanical ventilation, the battery pack assembly comprising: a connector communicatively coupled to a mating connector on a ventilator or on a compressor in the ventilator;a battery pack;an electronics for monitoring the battery cell status;a fuel gage containing one or more indicators located on the exposed exterior of the battery pack assembly so that the indicators are visible to a user when the battery pack assembly is inserted into a ventilator without requiring the user to remove the battery pack assembly from the ventilator, the one or more indicators indicating battery charge, in-use status, and fault. 13. The battery pack assembly of claim 12, the electronics further configured to provide charge to the Battery Pack Assembly Status Indicator when the battery pack is in use by the ventilator. 14. The battery pack assembly of claim 12, wherein the battery cell status comprises information about at least one of: state of charge, battery current, voltage, assembly number, revision, number of discharges, number of charges, date, in-use status, and fault. 15. The battery pack assembly of claim 12, wherein the one or more indicators display battery cell status of battery charge, in-use status, and fault. 16. The battery pack assembly of claim 15, wherein the information about fault includes information about over-charge, temperature, over-discharge, and voltage current charge. 17. The battery pack assembly of claim 12, wherein the one or more indicators are at least one of: a LED bar indicator and an alpha-numeric display. 18. The battery pack assembly of claim 12, wherein lighting the one or more indicators further comprises lighting the indicators displaying battery charge to correspond with the percentage of charge held by the battery, each indicator being lit when the battery reaches a certain percentage of charge. 19. The battery pack assembly of claim 12, wherein the battery pack assembly is hot swappable. 20. The battery pack assembly of claim 12, wherein the electronics is comprised of safety electronics and fuel gage electronics. 21. A method for indicating battery cell status on the exterior of a hot-swappable battery pack assembly used in a ventilator during mechanical ventilation, the method comprising: receiving information about the battery cell status from the battery pack;providing power to one or more indicators located on the battery pack assembly's exposed exterior, wherein power is provided: continuously when the battery pack assembly is inserted into the ventilator; andin response to a depressed test switch when the battery pack assembly is not inserted into the ventilator;lighting the one or more indicators based on the battery cell status, the indicators located on an exposed exterior of the battery pack assembly so that a user can view the indicators without removing the battery pack assembly from the ventilator. 22. The method of claim 21, wherein information about the battery cell status is determined by the electronics of the battery pack. 23. The method of claim 22, wherein power is provided to the one or more indicators by the electronics of the battery pack assembly. 24. The method of claim 21, wherein the battery cell status comprises information about at least one of: state of charge, battery current, voltage, assembly number, revision, number of discharges, number of charges, date, in-use status, and fault. 25. The method of claim 21, wherein the information about fault includes information about over-charge, temperature, or over-discharge. 26. The method of claim 21, wherein the one or more indicators are at least one of: a LED bar indicator and an alpha-numeric display. 27. The method of claim 21, wherein the one or more indicators display battery cell status of battery charge, in-use status, and fault. 28. The method of claim 21, wherein the test switch comprises a button, a flip switch, or a dial.
