A detection device and method for a lithium battery pack protection board

Abstract

The invention discloses a device and method for detecting a lithium battery pack protection board. The device comprises a shell, and a central processing unit, a power module, a first current detection module, a second current detection module and a voltage detection module are arranged in the shell. A display screen, a button set, a battery interface, a charge interface and a discharge interface are arranged on the shell. The positive pole of the battery interface is electrically connected with the positive pole of the charge interface and the positive pole of the discharge interface. The negative pole of the battery interface is electrically connected with the negative pole of the charge interface through the first current detection module, and the negative pole of battery interface is electrically connected with the negative pole of the discharge interface through the second current detection module. The two ends of the voltage detection module are electrically connected with the positive pole and the negative pole of the battery interface respectively. The central processing unit is electrically connected with the power module, the first current detection module, the second current detection module, the voltage detection module, the display screen and the key set. The device and method can quickly and accurately detect out whether the protection function of the lithium battery pack protection board is normal or not.

Description

technical field [0001] The invention relates to the technical field of detection of lithium battery packs, in particular to a detection device and method for a protection board of a lithium battery pack. Background technique [0002] At present, electric vehicles have been widely used in people's lives. With the development of the times, lithium battery packs are more and more widely used in electric bicycles. The lithium battery pack needs the protection of the protection board. The protection board is used as an electronic product to match the lithium battery pack and installed in the electric vehicle. Due to the harsh environment of use, the protection board of the lithium battery pack is often easily damaged and the lithium battery pack loses protection. In view of the above phenomena, the convenience and efficiency of after-sales service of lithium battery packs are particularly important. At present, the detection of lithium battery pack protection boards in the market...
