Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0013] figure 2 The physical detection function test method of the battery management system shown is realized by using the physical detection function test system of the battery management system. The input terminal of 1 is connected to the battery simulation model 1-2. The battery simulation model includes a driver model, a vehicle model and a battery pack model. The output port of the upper computer control module 1 is connected to the voltage simulation module 2, temperature simulation module 3, fault injection Module 4 is connected, the output signal of the voltage simulation module 2 is transmitted to the fault injection module 4 through the voltage signal of the single voltage simulation signal line 5, and the fault injection module 4 transmits the voltage signal to the battery management system 7, and the temperature simulation module 3 The tem...

Abstract

The invention, which relates to the technical field of electric vehicle manufacturing, discloses a physical detecting function testing method of a battery testing system. The method comprises: step one, carrying out physical detection accuracy testing; step two, carrying out battery state abnormality testing; step three, carrying out invalid value testing; and step four, carrying out electrical connection failure testing. Therefore, problems of high cost and low safety in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to a test method for the physical detection function of a battery management system of an electric vehicle. Background technique [0002] Now many companies test the physical detection function of the battery management system (BMS for short) of electric vehicles mostly by connecting the battery management system with a real battery pack (such as figure 1 shown), conduct charge and discharge tests, read the battery pack monomer voltage, temperature, total voltage, and total current values ​​through high-precision voltage, current, and temperature sensors, and compare them with the BMS detection results to obtain the BMS physical quantity detection accuracy of the battery management system However, the real battery pack cannot be used after a test, resulting in high production costs. At the same time, the power and voltage of the real battery pack are very high...
