A cooling system simulation model in a Matlab environment, allowing to analyze the battery module thermal state
Abstract
Introduction. The last decade development of an ecologically friendly transport sector is one of the most actively studied areas. The most notable achievement of automakers is the mass-production of electric vehicles.
The purpose of the study is to work out an effective methodology for a thermostatic control of a traction battery (TCTB), including the creation of a simulation model (SM).
Methodology and research methods. The simulation model is based on the standard SM in the Matlab/ Simulink environment. Its key component is a block of a closed channel (pipeline) for transporting liquid between the coolant components with the possibility of heat transfer. The necessary list of source data and circuit diagrams together with connection diagrams of Simulink blocks (in the Matlab environment) is presented. The principle of the system’s operation is described and the ways to implement each particular component of SM and the cooling system of electric transport vehicles (ETV) as a whole are indicated.
Scientific novelty and results. One of the main obstacles to replace vehicle internal combustion engines with electric motors is the safety and reliability of the ETV. One of the main safety criteria for TSTB is its operation in the optimum temperature range. This fact stimulates the creation of TSTB cooling systems to control the operational properties both of single batteries and TSTB in general. When modeling the operation and condition of the components, a natural heat sink (5 W/m2 ∙°С) was implemented. This aspect has been reflected in the findings of the study and demonstrated the efficient cooling performance of the model.
Practical significance. This SM opens up great opportunities for the development of temperature control systems as it permits to select components at the stage of system design. The article presents conclusions on the results of battery thermal modeling of an electrobus battery.
