Problems solved by technology
Special equipment and manual input are required, and the test time is very long. During the test, because the battery is separated from the system, the reliability of the backup power of the entire system is reduced, and the battery is discharged through a dummy load, which wastes energy in vain.
In addition, in a large number of sites, it is difficult to maintain the power system of the whole network in this way

The invention discloses a power system capable of realizing online battery detection, which comprises a battery pack, a monitoring module, a rectifier module and a rectifying / inverting bidirectional module, wherein the battery pack is connected with a load through a test switch; the monitoring module is used for controlling the battery pack for battery detection; one end of the rectifier module isconnected with the mains supply and the other end is connected with the load for rectifying the inputted mains supply and providing power for the load and charging the battery pack in normal work; and one end of the rectifying / inverting bidirectional module is connected with the mains supply and the other end is connected with the battery pack for providing power for the load and charging the battery pack in a rectifying mode in normal work, and working in an inverting mode in the case of battery test to output battery discharging current. Online battery pack test for the power system can berealized, the test process is reliable and environmental friendly, and maintenance on the full network power supply system can be realized.
Description
technical field [0001] The invention relates to a power supply system, more specifically, to a power supply system capable of realizing on-line battery detection. Background technique [0002] In many applications, the power system will be connected with a battery pack as an energy storage element to provide backup power. In the application, the battery pack needs routine maintenance of charging and discharging the battery to judge the health status and remaining capacity of the battery. [0003] The current detection method needs to disconnect the battery from the power system for off-line charge and discharge test. Special equipment and manual input are required, and the test time is very long. During the test, because the battery is separated from the system, the backup power reliability of the entire system is reduced, and the battery is discharged through a dummy load, which wastes energy. In addition, in a large number of sites, it is difficult to maintain the power ...
