Battery module with abnormality detection function and power storage apparatus and method of operating the same

A power storage apparatus installed inside an uninterruptible power supply cabinet and uninterruptedly supplying power, the power storage apparatus comprising:

• at least one battery module with an abnormality detection function, and each battery module comprising:
• a body;
• a battery assembly disposed inside the body, and the battery assembly having a plurality of battery units electrically connected to each other;
• a protection unit disposed inside the body and connected in series to the battery assembly, and the protection unit having a first end and a second end;
• and
• a detection unit disposed inside the body and connected in parallel between the first end and the second end of the protection unit, and the detection unit comprising:
• an indication element configured to be enabled by a voltage difference value between the first end and the second end when the voltage difference value is greater than a voltage setting value;
• and
• a charging module connected in parallel to the at least one battery module and configured to charge the at least one battery assembly of the at least one battery module.

A method of operating a battery module with an abnormality detection function comprising steps of:

• (a) providing a battery module, wherein the battery module comprises a battery assembly, a protection unit, and a detection unit;
• (b) providing a first current path and a second current path;
• wherein the protection unit and the battery assembly are located on the first current path, and the detection unit and the battery assembly are located on the second current path;
• and
• (c) flowing an operation current through the second current path when the protection unit is disconnected;
• flowing the operation current through the first current path when the protection unit is not disconnected.
