Abstract

The invention discloses a method for debugging a BMS lower computer by utilizing an upper computer. The method comprises the following steps: data are monitored; a function of periodically transmitting the data of the lower computer is debugged; the data are calibrated; the functions of receiving ID data and transmitting the ID data of the lower computer are debugged; the data are processed; the periodically transmitted data and calibrated data are processed, and when information of the data is confirmed to be correct, the data of the lower computer are normal; hardware is controlled; and a relay, a data input port and an output port are controlled, and normality of the data of the functional relay, the data input port and the output port are judged. A BUG of the lower computer can be more comprehensively tested by the test scheme, and repairing can be performed before publishing so that subsequent program writing, production and maintenance are more facilitated, troubles of program re-writing are reduced for clients, and thus specialty of companies in such aspect can be greatly enhanced.

Description

technical field [0001] The invention relates to the field of battery management, in particular to a method for debugging a BMS lower computer by using an upper computer. Background technique [0002] The battery management system is an important management unit of the battery system for electric vehicles. At present, after the design and processing of the management system are completed, they are directly loaded into the battery system. Due to the high energy of the battery system, there are risks such as short circuit and burning of the battery management system. If the basic performance and functions of the management system are tested before the battery management system is installed in the battery system, the risk can be reduced. The main function of the battery management system is to measure the total voltage of the battery pack in the battery system, the cell voltage, the charge and discharge current of the battery system, and the temperature of the battery pack in t...
