<p align="justify">This research titled “Simulation and Crashworthiness Analysis of Sandwich Panel Structures for Protection on Battery Module in Electric Vehicles Subjected to Ground Impact” is carried out because people nowadays are living in a high level of mobility to fulfill their life necessities, so transportation’s technology needs to occupy the demands, and electric vehicle is the right answer. But due to the increasing numbers of vehicles, it came out to be negative impact to the environment, therefore electric vehicle (EV) is developed. But, unfortunately the main power source in EV, that is battery, is so fragile that can explode if its Lithium ion exposed to the air, so a super protective structure is needed, but the protector must be light-weight and can reduce any external forces’ effect, such as dynamic loads. For example, a rock that fly and hit the lower part of vehicle is a dynamic load. The goal of this research is to analyze crash event in protective structure of battery and to determine the most effective which sandwich panel geometry for battery’s crashbox. There are two sandwich geometries, Blast Resistant Adaptive Sandwich (BRAS) and Navy Truss (NavTruss) with aluminum as materials in both sandwiches due to the it is lightweight. The geometries are modeled by finite element method in LS-DYNA by using numerical simulation. The dynamic loads use simple kinematics, only translation in z-axis. The result is analyzed in the manner of crashworthiness theory with some varied cases. It is concluded that BRAS geometry is the most effective geometry for battery’s crashbox. <p align="justify"> <br />
