Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] like figure 1 A new energy vehicle power battery management system hardware-in-the-loop test platform is shown, which includes a battery cell simulation unit 2, a battery cell electrical fault injection unit 3 and an I / O signal electrical fault injection unit 4;

[0022] Wherein, the battery cell simulation unit 2 is used to send the battery cell electrical fault mode configuration information to the battery cell electrical fault injection unit 3 under the control of the computer 1 (RTPC real-time computer);

[0023] The battery cell electrical fault injection unit 3 is used to input the configuration information of the battery cell electrical fault mode into the tested BMS controller 5, so that the tested BMS controller 5 performs a corresponding battery cell electrical fault mode test;

[0024] The I / O signal electrical fault injection...

Abstract

The invention discloses a hardware-in-loop test platform for a new energy vehicle power battery management system. A battery cell simulation unit of the hardware-in-loop test platform is used for sending battery cell electrical failure mode configuration information to a battery cell electrical failure injection unit under the control of a computer; the battery cell electrical failure injection unit is used for inputting the battery cell electrical failure mode configuration information into a measured BMS controller so that the measured BMS controller is used for carrying out a correspondingbattery cell electrical failure mode test; an I / O signal electrical failure injection unit is used for inputting I / O signal failure configuration information into the measured BMS controller under thecontrol of the computer so that the measured BMS controller is used for carrying out a corresponding I / O signal failure test of the measured BMS controller. Complete hardware-in-loop automated testing, including full-function testing of a main board and a slave board, of the battery management system can be realized, so that the reliability of the battery management system is improved.

Description

technical field [0001] The invention relates to the technical testing field of new energy vehicle power batteries, in particular to a new energy vehicle power battery management system hardware-in-the-loop testing platform and testing method. Background technique [0002] For new energy vehicle power battery management system (BMS) hardware-in-the-loop test platform. Today's mainstream battery management system hardware generally includes a control board and multiple acquisition slave boards. The current in-the-loop test platform only conducts related tests on the control board in the BMS, and does not perform corresponding tests on the acquisition slave boards. When testing, only use the model or code to simulate the parameters of the single battery. The BMS test result obtained in this way is inaccurate, which affects the reliability of the BMS test. Contents of the invention [0003] The purpose of the present invention is to provide a new energy vehicle power battery...
