Abstract

The invention provides hardware testing equipment of a battery management system and belongs to the technical field of a battery management system of an electric automobile or a large-power energy storage power station, aiming at solving the problems of an existing battery management system that the testing efficiency is low and errors are great. An isolation power supply module provides an isolation power supply for a signal processing module and a touch screen module; after a PCBA (Printed Circuit Board Assembly) board card of a battery management system to be detected is fixed on a testing needle bed, and a testing point on the PCBA board card is in tight contact with a probe on the testing needle bed; a signal acquisition wiring harness of the testing needle bed is connected with a testing signal input end of the signal processing module; an input / output end I of the signal processing module is connected with the input / output end of the touch screen module; an input / output end II of the signal processing module is connected with a wiring end of a USB (Universal Serial Bus) interface, and an interface end of the USB interface module is connected with a USB interface of external equipment. With the adoption of the hardware testing equipment of the battery management system, the testing precision and the testing efficiency are improved. The hardware testing equipment is suitable for testing the battery management system.

Description

technical field [0001] The invention belongs to the technical field of battery management systems for electric vehicles or high-power energy storage power stations, and relates to a battery management system hardware testing technology. Background technique [0002] As one of the core components of the electric vehicle electronic control system, the electric vehicle battery management system has high requirements for its reliability. The electric vehicle battery management system generally consists of a main control board and a voltage acquisition board. During the production process of the main control board and the voltage acquisition board, testing the important signals and parameter indicators on the hardware PCBA board is an important means to evaluate and ensure the performance and reliability of the battery management system. At present, one is to use a multimeter, oscilloscope, etc. to test manually, but this method takes a lot of time due to the large number of sig...
