The invention relates to automatic test equipment for a Motorola lithium battery BQ protection board. A computer is in one-way connection with a HP6624 direct current power supply, a HP6632A direct current power supply, a HP3488A multiplexer and a HP6063B load circuit respectively through a GPIB (General Purpose Interface Bus)-USB (Universal Serial Bus) card; the HP6624 direct current power supply is in one-way connection with the HP3488A multiplexer and a fixture respectively; a programmable direct current power supply is in one-way connection the multiplexer and in one-way connection with the fixture through the HP6063B load circuit; the HP6063B load circuit is in one-way connection with the HP3488A multiplexer; and a universal meter is in one-way connection with the fixture and an interface data display of the computer respectively. The automatic test equipment has the characteristics that the computer is adopted for full digital control, and the automatic test equipment has the advantage that the test is accurate and stable, has the out-of-tolerance alarm function and can continuously test 32 connection plates.
Description
technical field [0001] The invention relates to an automatic test device for a lithium battery protection board, in particular to an automatic test device for a MOTOROLA lithium battery BQ protection board. Background technique [0002] Due to the high volume density and energy density of lithium batteries, and a single battery voltage as high as 4.2V. , In order to ensure the safety of use, the lithium battery must have a corresponding battery management circuit in the application to prevent the battery from overcharging, overdischarging and overcurrent. At present, there is no test equipment for MOTOROLA lithium battery protection board on the market, which cannot meet the needs of actual testing. Contents of the invention [0003] In view of the above problems, the present invention provides a MOTOROLA lithium battery BQ protection board automatic test equipment, the specific technical solution is, a MOTOROLA lithium battery BQ protection board automatic test equipment...
