Battery Management System
First Claim
1. A battery management system for one or more batteries coupleable to a healthcare delivery system, the one or more batteries coupled to the healthcare delivery system when the system is not coupled to an alternate power supply, the system comprising:
- a display unit;
a controller coupled to the display unit and programmed;
to determine when the healthcare delivery system is coupled to the one or more batteries,to control the display unit to display an initial number corresponding to a time remaining on battery (TROB) when the healthcare delivery system is coupled to the one or more batteries,to determine if the TROB is within a reserve range extending up to a reserve range maximum, the reserve range maximum being less than a maximum TROB,to change the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum, andto decrease the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum.

Abstract
A battery management system is provided for one or more batteries. The system includes a display unit, and a controller coupled to the display unit and programmed to determine when a healthcare delivery system is coupled to the one or more batteries, to control the display unit to display an initial number corresponding to a time remaining on battery (TROB) when the healthcare delivery system is coupled to the one or more batteries, to determine if the TROB is within a reserve range extending up to a reserve range maximum, the reserve range maximum being less than a maximum TROB, to change the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum, and to decrease the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum.

13. A healthcare delivery system comprising:
-
one or more batteries; a portable pump for use in intravenous delivery of medical fluids, the portable pump being coupleable the one or more batteries; a display unit; an input unit; a pump controller coupled to the portable pump, the display unit and the input unit, the pump controller programmed to receive an input from the input unit and to control the portable pump to enter an operational state according to the input received; and battery management system comprising a charger coupled to the one or more batteries and a controller coupled to the display unit, wherein the controller is programmed; to determine when the portable pump is coupled to the one or more batteries, to control the display unit to display an initial number corresponding to a TROB when the portable pump is coupled to the one or more batteries, to determine if the TROB is within a reserve range extending up to a reserve range maximum, the reserve range maximum being less than a maximum TROB, to change the TROB according to an operational state of the healthcare delivery system if the TROB is greater than the reserve range maximum, to decrease the TROB without regard for the operational state of the healthcare delivery system if the TROB is less than the reserve range maximum, to activate the charger when the portable pump is coupled to the mains voltage to charge the one or more batteries, and to increase the TROB either by a first increment or to the TROB maximum according to a recharge state of the one or more batteries. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
