Embodiment

[0029] The technical problem of the present invention is to provide a set of working environment consisting of a monitoring computer, a real-time computing platform and supporting external auxiliary equipment, so as to realize the operation simulation of various types of working conditions for PBS under the background of different vehicle types. The working environment needs to be able to establish a vehicle-related system model to simulate the electric power loading demand under the set working conditions and the thermal environment boundary condition loading of the PBS (mainly temperature and humidity conditions); at the same time, the working environment will also accept the current status monitoring information of the PBS , simulate the actual vehicle controller strategy through a mathematical model, and adjust these power and temperature and humidity loading requirements in real time according to the expected output at the next moment and the vehicle and environmental condi...

Description

technical field [0001] The invention relates to a power battery system simulation test platform, in particular to a power battery system hardware-in-the-loop simulation test platform. Background technique [0002] The power battery system (PBS) is one of the main energy storage devices for various electric and hybrid vehicles. PBS includes two parts: power battery (PB for short) and battery management system (BMS for short). Its main functions include: single battery status monitoring, battery pack status monitoring, thermal management, fault monitoring and alarm, in-package communication and vehicle communication. PBS hardware-in-the-loop simulation test platform will not be easy to establish a mathematical model PB and BMS together to achieve hardware-in-the-loop. Take the real-time computing platform as the working environment, run the vehicle power system model, vehicle longitudinal dynamics model and vehicle thermal management model on it, and simulate PBS under vario...
