Embodiment 1

[0043] The method for collecting data distribution of a DCDC converter provided in this embodiment is to increase the data distribution collection function in a system loaded with DCDC converter software, and when the system is in a charging condition or a normal driving condition, the Statistical counting of key parameters and fault states. Wherein, in this embodiment, the system is a new energy vehicle.

[0044] as attached figure 2 described, including the following steps:

[0045] S1: Obtain basic data from the storage.

[0046] In this embodiment, the step S1 further includes judging whether the DCDC converter is powered on before acquiring the basic data from the memory, and only when the DCDC converter is powered on, it is necessary to obtain the basic data from the memory. Get the basic data in the memory.

[0047] First of all, it should be noted that whether the DCDC converter is powered on or not is not directly related to the driving state of the new energy ve...

Embodiment 2

[0070] The difference between this embodiment and Embodiment 1 is that the timing of updating the coded data and the count of the coded data to the memory in this embodiment is not only after the DCDC converter is powered off, but also after During operation of the method for collecting data distribution of the DCDC converter, all the encoded data and the count of the encoded data are periodically updated to the memory.

Embodiment 3

[0072] The difference between this embodiment and Embodiment 1 is that step S2 of this embodiment also includes fitting the index numbers of two or more of the key parameters to obtain a composite index number, and the composite index number is the code For data, the collection in step S2 is periodic collection, the duration of the cycle is determined by the nature of the key parameter, and the count of the composite index number is increased by 1 in each cycle. In this embodiment, for a multi-dimensional interval composed of two or more parameters, the composite index number is fitted according to the interval index numbers of different parameters, and the fitting criterion is: the obtained composite index number has a unique solution, namely The unique interval index number can be obtained by parsing. Fitting the interval of the output voltage and the input current to obtain the composite index number of the output voltage and the input current, adding 1 to the count of the ...

Abstract

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 converter, and realize complete recording of the working conditions experienced by the DCDC converter in the whole life cycle.

Description

technical field [0001] The invention relates to the technical field of DCDC converters for new energy vehicles, in particular to a method and device for collecting data distribution of DCDC converters. Background technique [0002] With the rapid development of the modern economy and the improvement of people's living standards, especially the improvement of the general public's awareness of environmental protection, the application of new energy vehicles is becoming more and more popular. The vehicle performance of the car plays a key role, such as the attached figure 1 As shown, it is a typical automobile electric drive system. The power source of the DCDC converter 1 is the automobile power battery pack. The DCDC converter 1 mainly supplies power to the vehicle electrical appliances, and is responsible for converting the energy of the high-voltage battery 2 into the low-voltage power supply network of the vehicle. While supplying power to low-voltage loads such as automo...
