The invention, which belongs to the field of the battery PACK technology, discloses a hand-held power battery PACK tester and a control method thereof. The tester is composed of a battery PACK plugging member, a switch array, a battery check circuit, a master control chip, and a display device. The input terminal of the master control chip is connected with the output terminal of the battery check circuit through another path of SPI interface; the input terminal of the battery check circuit is connected to the output terminal of the switch array; the input terminal of the master control chip is connected with the output terminal of the switch array by the battery check circuit; and a battery PACK is connected with the input terminal of the switch array by the PACK plugging member. In addition, the invention also discloses a control method of the hand-held power battery PACK tester. Compared with the traditional method for measuring all batteries in the battery pack one by one by using a universal meter manually, the method disclosed by the invention has the following advantages: the checking efficiency, the checking accuracy, and the checking coverage surface of the battery PACK are improved and the labor cost is reduced substantially.
Description
technical field [0001] The invention relates to the field of battery PACK technology, in particular to a hand-held power battery PACK tester and a control method thereof. Background technique [0002] Battery PACK refers to the packaging, packaging, and assembly of multiple batteries. During use, it is necessary to check whether the wiring sequence of the batteries in the PACK is correct, whether the battery voltage is consistent, whether the internal resistance of the battery is normal, and whether the battery current is stable. Whether it is consistent to ensure that the assembled battery can be put into use. [0003] At present, the detection of the wiring sequence of the batteries in the PACK is mainly to manually use a multimeter to measure the voltage difference of the batteries one by one to determine whether the wiring sequence is correct, to measure the voltage of multiple batteries one by one to determine the consistency of the batteries, and to measure the voltage...
