Abstract

The invention provides a technique to realize dynamic charge management and a state of health estimation of a battery of an X-ray machine upgrade kit in an x-ray system. The X-ray machine upgrade kit includes a detector, a workstation, a monitor, a docking and a charger, among others. A rechargeable battery powers portable nature of the detector and the workstation. The docking and the chargers are integrated as a part for charging the detector battery and the workstation battery and also communicating with the workstation. The workstation is a core controller of the system, which allows controlling the detector, the docketing or the charger and the monitor. All communications are wireless or wired.

BATTERY MANAGEMENT METHOD USED ON X-RAY MACHINE UPGRADE KIT

FIELD OF INVENTION

The invention generally relates to an X-ray machine and more particularly a technique for estimating state of health of a battery and realizing battery management utilized by the X-ray machine.

BACKGROUND OF THE INVENTION

An X-ray machine upgrade kit utilizes a battery, which is charged by substantially constant charge current. The upgrade kit does not estimate state of health of the battery.

A conventional technique includes an apparatus to determine a state of health of battery based on time duration and constant charge current. However, the technique does not manage charging of the battery simultaneously with estimation of state of its health.

Hence there exists a need for an efficient technique to estimate state of health and manage charging of the battery.

BRIEF DESCRIPTION OF THE INVENTION

The invention provides a technique to realize dynamic charge management and a state of health estimation of a battery in an X-ray machine upgrade kit. The X-ray machine upgrade kit includes a detector, a workstation, a monitor, a docking and a charger, among others. A rechargeable battery powers portable nature of the detector and a workstation. 

DETAILED DESCRIPTION OF THE INVENTION

The invention provides a technique to realize dynamic charge management and a state of health estimation of a battery of an x-ray machine upgrade kit in an X-ray system. The X-ray machine upgrade kit includes a detector, a workstation, a monitor, a docking and a charger among others. FIG. 1 depicts the X-ray machine upgrade kit in a block diagram.

FIG. 1

A rechargeable battery powers portable nature of the detector and the workstation.  The docking and the chargers are integrated as a part for charging the detector battery and the workstation battery and also communicating with the workstation. The workstation is a core controller of the system, which allows to control the detector, the docking or the charger and the monitor. All communications are wireless or wired. There are two batteries for the detector. One of the batteries is used for working and another is used for back up. Both the batteries are placed in the docking. The docking powers and charges the workstation, when the workstation is inserted into the docking. The batteries management in a user interface (UI) on the monitor provides three batteries status. The status includes state of the detector battery while utilization, the state of battery while charging and state of the workstation battery while working. FIG. 2 depicts the docking or charger schematic block diagram.

FIG. 2

For the dynamic charging management there is multi charging level setting, for instance, slow speed charging, normal speed charging and high speed charging. One or two of the detector battery is in normal speed charging mode by default. When the workstation is placed into the docking, the batteries turn to slow speed charging mode. The charging mode is co...
