Problems solved by technology

The disadvantage of this method is that the evaluation is carried out on the basis of the whole vehicle, so it is not conducive to shortening the development cycle
Secondly, the existing evaluation methods are fault-prompting, that is, in the evaluation process, the faults that occur can only be analyzed passively, and it is impossible for the testers to completely autonomously create an application environment that induces or simulates possible faults

Embodiment Construction

[0029] Hereinafter, the present invention will be specifically described based on the drawings showing the embodiments of the present invention.

[0030] figure 1 A schematic diagram of the architecture of a typical automotive power supply system. Such as figure 1 As shown, the vehicle power supply system 10 includes a starting system 101 , a power supply system 102 , a power management system 103 and a power distribution system 104 . The starting system 101 refers to a starter. The power supply system 102 is also called the charging system, including storage batteries and generators, which convert chemical energy and mechanical energy into electrical energy, and supply them to the starting system 101 and the power consumption system 20 (that is, the collection of energy-absorbing components, such as air conditioners, igniters, etc.) ) output power. The power management system 103 is used for coordinating the management and supply of electric energy, so as to achieve the p...

Abstract

The invention relates to an automobile electronic technology, in particular to a method and a system for evaluating performance of a power supply system of an automobile. The method for evaluating the performance of the power supply system of the automobile comprises the following steps of: determining a group of input parameters including an electricity utilizing load demand and an electricity utilizing duration of a starting system and/or electrical components of a tested automobile; according to the input parameters, controlling the power supply system to supply power to the starting system and/or the electrical components by using a power management system; acquiring running parameters of the power supply system; and according to the running parameters, evaluating the performance of the power supply system of the automobile. Compared with the prior art, the method and the system for evaluating the performance of the power supply system of the automobile have the advantages that: an electric quantity matching test of the whole automobile is not required; functions and reliability of a power diagnosing system are improved; and on-line dynamic electric quantity matching balance is realized and risk evaluation is started.

Description

technical field [0001] The invention relates to automotive electronic technology, in particular to a method and a system for evaluating the performance of a power supply system of a hybrid electric vehicle and an electric vehicle. Background technique [0002] In the current automobile development process, in order to evaluate the performance of the automobile power supply system, it is generally carried out through the method of vehicle power matching test. The disadvantage of this method is that the evaluation should be carried out on the basis of the whole vehicle, so it is not conducive to shortening the development cycle. Secondly, the existing evaluation methods are fault-prompting, that is, during the evaluation process, the faults that occur can only be analyzed passively, and it is impossible for testers to completely autonomously create an application environment that induces or simulates possible faults. Contents of the invention [0003] The present invention ...
