Embodiment Construction

[0024] Embodiments of the present invention are described in detail below.

[0025] Such as figure 1 It is the communication between the battery management system, the battery simulation device and the upper computer of the present invention. They communicate through the CAN bus. The battery simulation system simulates and outputs the voltage, temperature, current and other information of the battery according to the needs of different batteries. The battery management The system collects its output information and displays it on the host computer system. On the one hand, it can judge whether the output is correct. On the other hand, it is convenient for the battery management system to debug, calibrate, diagnose, and do experiments. It provides a comprehensive test platform for the battery management system. The battery simulation system can also read out the contactor information and feed it back to the host computer through the CAN message, and the host computer can display...

Abstract

The invention provides a battery simulating system, which comprises a battery simulator controlled by a single chip machine, and further comprises a battery management system which collects the voltage, temperature and current information output by the battery simulator and feeds the information back to an upper computer; and an upper computer for setting the battery simulator, displaying the work state and output information of the battery simulator and displaying the voltage, temperature and current information fed back by the battery management system. The battery simulator further comprises a voltage module consisting of DA chips, a temperature module and a current module. The single chip machine can control the gating and the output of the voltage module, the temperature module and the current module according to a battery parameter setting command and a switch parameter setting command of the upper computer. The upper computer, the battery management system and the battery simulator are connected through a CAN bus. The invention can simulate and output the voltage, temperature and current information of the battery and provide a comprehensive test platform for debugging, calibrating, diagnosing and testing the battery management system.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to a battery simulation system. Background technique [0002] At present, electric bicycles, hybrid vehicles, electric vehicles, and fuel cell vehicles powered by lead-acid batteries, nickel-metal hydride batteries, and lithium batteries have received more and more attention from the market. The application of power batteries in the field of transportation is of great significance for reducing greenhouse gas emissions, reducing air pollution and the application of new energy. However, the problems restricting the development of electric vehicles are still energy storage batteries and application technologies. How to improve the energy efficiency and operational reliability of batteries is a problem that must be solved in the industrialization of electric vehicles. It is of great significance to study battery management technology and systems. In order to better ...
