Document Type and Number:
WIPO Patent Application WO/2020/233693
Kind Code:
A1
Abstract:
Provided in the present application are an uninterruptible power supply (UPS), a power supply system and a battery capacity test method, which may accurately detect the total battery capacity of a system, and during capacity testing and when mains electricity is abnormal, the backup time of a power supply system is sufficient. The UPS is separately connected to a load and at least two battery packs, and the UPS comprises a testing unit used for carrying out individual capacity testing on each battery pack among the at least two battery packs so as to acquire the battery capacity of each battery pack, wherein when the battery capacity of each battery pack is measured, the other battery packs besides each of the battery packs do not discharge electricity and have backup power. The UPS also comprises a determination unit used for determining the total battery capacity of the at least two batteries according to the battery capacity of each battery pack.
