1. A control method applicable to a rack server system, comprising:
- establishing a communication link between the rack server system and a battery backup unit, wherein the battery backup unit is connected to a power input port of the rack server system, and comprises a plurality of battery modules connected with each other in parallel;
controlling the battery backup unit by the rack server system to perform a validity test on a first battery module of the battery modules during a first period, wherein the validity test further comprises increasing the output voltage of the battery backup unit supplied to the rack server system while the rack server system is supplied with a main power to the rack server system;
controlling the battery backup unit by the rack server system to perform the validity test on a second battery module of the battery modules during a second period, wherein the first period and the second period are not overlapped with each other; and
determining a default loading by the rack server system based at least upon the results of the validity tests on the first battery module and the second battery module, wherein the default loading is adjusted based at least upon a number of battery modules that failed the validity test.

Abstract
A rack server system and a control method thereof are provided. The rack server system establishes a communication link for communicating with a battery backup unit. The battery backup unit is connected to a power input port of the rack server system, and includes a number of battery modules connected with each other in parallel. The rack server system controls the battery backup unit to perform validity test on a first battery module during a first period and to perform validity test on a second battery module during a second period, wherein the first period and the second period are not overlapped with each other.

10. A rack server system, comprising:
-
a power input port connected to a battery backup unit, wherein the battery backup unit comprises a plurality of battery modules connected with each other in parallel; a communication interface establishing a communication link for communicating with the battery backup unit; a control unit connected to the communication interface for controlling the battery backup unit to perform a validity test on a first battery module of the battery modules during a first period by increasing the output voltage of the battery backup unit supplied to the rack server system and controlling the battery backup unit to perform a validity test on a second battery module of the battery backup unit during a second period by increasing the output voltage of the battery backup unit supplied to the rack server system, wherein the first period and the second period are not overlapped with each other; and wherein the rack server system further determines a default loading based at least upon results of the validity tests on the first battery module and the second battery module; and
wherein the default loading is adjusted based at least upon a number of battery modules that failed the validity test. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
