Abstract

The invention provides a battery management unit address calibration system and method. The address calibration method comprises the steps of reading a barcode and an address number to be tested on abattery management unit casing to be tested, and performing transmitting; extracting a pre-stored barcode and an address number from a database, and matching with the barcode and the address number tobe tested; if not, determining that the battery management unit address calibration is unqualified; if matching, writing the address is in the battery management unit, determining whether the addressis successfully written, and verifying the address calibration. According to the address calibration method, automatic address distribution, automatic address identification, automatic writing and automatic verification are achieved, and a calibration result can be automatically uploaded to a manufacturing enterprise production process execution management system to improve a production efficiency.

Description

technical field [0001] The invention relates to the field of distributed power management of automobile batteries, in particular, but not exclusively, to the calibration and detection of the address of a battery management unit in a power management system. Background technique [0002] The battery management unit (BMU) is responsible for cell voltage collection, temperature collection, and cell balance control of the batteries in each battery module, and communicates to the main control unit ( BCU) feeds back important information in real time. In the actual production of battery management systems, when the control strategy is determined, the number of battery management units is determined according to the number of batteries. Therefore, there is a main control unit connected to multiple battery management units, so that It is necessary to establish a set of methods for address calibration and detection of the battery management unit. Contents of the invention [0003]...
