Battery cell tests protection circuit

The utility model provides a battery cell tests protection circuit for on concatenating the return circuit of formation by battery cell and monomer test module, this battery cell tests protection circuit includes that one is used for the one -way device through unilateral electric current and one is used for flowing through the electric current and is greater than the fuse of realizing automatic disconnection when presetting the threshold value, wherein, one -way device and monomer test module be carried forward and concatenating mutually with the fuse abreast, and the positive pole of one -way device and battery cell 's negative pole links to each other, and the negative pole of one -way device passes through the fuse and links to each other with the anodal of battery cell. Implement the utility model discloses, when battery cell the negative pressure appears or damages, avoid battery cell 's negative pressure or damage the harm to monomer test module, improved storage battery detection system security natur
