This battery thermal management calibration test bench applies the same development as that applied by most domestic OEMs, main engine plants and electronic control system suppliers so that the students can have the latest technical experience in a timely manner and acquire the abilities to apply related development environment in the process of learning. Students accomplishing this teaching module can seamlessly start their careers by working in related OEMs, main engine plants and electronic control systems, as well as various engine parts production suppliers.
This battery thermal management calibration test bench is mainly designed for the undergraduate students of automotive related majors so as train talents such as test equipment operators, test engineers, calibration engineers and product engineers.
The following teaching purposes can be achieved through this battery thermal management experiment bench:
1.Truly operational battery thermal management system is provided where all parts are installed on the stand for easy disassembly. Students can master the structure and connection approaches and key points of the battery thermal management system during the disassembly and assembly processes. If the battery has sufficient power, it can be actually operated so as to fully demonstrate the composition and working processes of the battery thermal management system.
2.Master the composition of the battery thermal management system of electric vehicles, the structure and working principle of each functional component, the functional diagram of the sprayed image on the panel diagram as well as the vivid expression of the execution process of the parts.
3.Master the hardware and software architecture of the battery thermal management system.
4.Master the basic software logic of the battery thermal management system, such as state of charge (SOC) calculation, state of health (SOH) calculation, signal acquisition, thermal management control and relay control.
5.Master the calibration approaches and principles of the battery thermal management system parameters based on the calibration software for the following purposes:
