The Simulation Analysis on Side Collision Safety of Electric Buses

Article Preview

With energy and environmental issues outstanding, electric vehicles have got much room for developments, which also brings a lot of security risks different from the traditional internal combustion engine vehicle such as the electrolyte spillage; toxic fumes; electric shock and so on. This paper simulates the progress of a electric bus side collision with LS-DYNA, and analyzes its security mainly from aspects of the electrical injury and electrochemical injury: internal short-circuit occurs in battery monomer, external short-circuit outside the battery pack occurs or even cause a fire, BMS, fast fuse and other electronic components with too large deformation in a collision will lose its ability of monitoring external short-circuit of battery pack. Meanwhile, we analyze reasons for the three phenomena above and propose measures for improvement, fix methods and structure of the weak components in collision zone have been improved. Then this paper verifies vehicle security after improvement reducing the electrical injury and electrochemical injury the vehicle on passengers.
