Electric Vehicle Conversion Software Safety Study by Mean of Model Based System Design (MBSD) Approach

Although electric vehicle conversion option has gained more attention for commercial use, there are questions regard to functional safety aspects. One of them is the software being employed within the system such as, electric propulsion system, battery system, and communication system and others. Thus, this work aim to employ model based design approach to investigate by mean of examination possible safety requirement parameters range and failure scenario. The procedure includes building of systematic models of electric vehicle conversion sub-subsystem, power flow system, traction and vehicle dynamic system, and communication system. Then, the system is simulated based on technical requirement of the particular electric vehicle conversion. Furthermore, in-the-loop test will be used to study the software algorithm within the electric conversion system. The results will be analyzed and evaluated before the algorithm is embedded and tested in actual electric vehicle conversion vehicle lab vehicle before employing in the real field test.
