Method and device for acquiring data distribution of DCDC converter

The invention discloses a method and device for acquiring data distribution of a DCDC converter, which is applied to a new energy automobile. The new energy automobile comprises a memory and a DCDC converter. The acquisition method comprises the steps of S1, acquiring basic data from the memory; S2, periodically collecting key parameters of the DCDC converter, converting codes of the key parameters into coded data, and updating the count of the coded data; and S3, updating the count of the coded data to a preset position of the memory according to the coded data, wherein the coded data and thecount are the basic data, and the key parameters are state parameters of the DCDC converter during operation. The invention also provides a system for acquiring the data distribution of the DCDC converter. The method and system provided by the invention for acquiring the data distribution of the DCDC converter do not need to add any hardware cost, periodically acquire the key parameters and faultstates of the DCDC conver
