Abstract

The invention provides a power supply analyzer and a temperature compensation method thereof, and relates to the technical field of power supply characteristic detection. The method comprises the steps: acquiring target data which comprise the environment temperature of an environment where a to-be-detected power supply is located and a current cold start current value of the to-be-detected powersupply; determining an adjustment coefficient of the current cold start current value based on the environment temperature; and determining a target cold start current value of the to-be-detected power supply by using the current cold start current value and an adjustment coefficient. Therefore, a technical problem of relatively low measurement accuracy of the cold start current of the power supply in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power characteristic measurement, in particular to a power analyzer and a temperature compensation method thereof. Background technique [0002] Since the characteristics of the power supply will change with the change of temperature, the most important measurement parameter of the car starting power analyzer is the CCA value (cold cranking current). However, under the influence of ambient temperature, the CCA value measured in the prior art will fluctuate with the temperature change, which leads to the low accuracy of the CCA value obtained when the existing power analyzer measures the CCA value of the car starting power supply. . [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a power analyzer and its temperature compensation method, so as to alleviate the technical pr...
