Model-in-Loop Automated Test Based on Function Requirements of BMS 2018-01-0434

It is important to verify the requirements of battery management strategy (BMS), which is directly related to the safety of the electric vehicles. A model-in-loop test framework was established to realize the automated test based on the application scenario of BMS, including battery simulation module, battery management strategy module, test sequence module and function assessment module. The inputs of the automated test were designed in the test sequence module. The function requirements of state estimation, balance control, security protection, thermal management and fault diagnosis were designed in the function assessment module. The test results show that the proposed model-in-loop test can reach 100% of function requirements, and 87% of execution coverage. Additional automated test cases can be added to the proposed model-in-loop test, and it will be an effective method to the requirements verification of battery management strategy.
