1. A mobile X-ray apparatus comprising:
- an X-ray radiator configured to generate and emit X-rays;
a battery configured to supply power to the X-ray radiator;
a charger configured to charge the battery;
a battery management system, comprising a battery stack monitor circuit, configured to determine a state of the battery by detecting at least one of a voltage and a temperature of the battery;
a direct current DC-to-DC converter configured to convert the power supplied by the battery into a driving power for driving the battery management system; and
a first switch configured to prevent power from being supplied to the DC-to-DC converter based on a control of the battery management system,wherein the battery management system is further configured to be shut down when the first switch is turned off, and the first switch is further configured to be turned on by power supplied from the charger when the battery management system is shut down.
