Abstract: Batteries have a risk of fire due to vibrations and shocks generated during transportation. In this paper, the vibration history of an actual truck was measured and compared with the existing battery transportation standards. The actual truck vibration was measured by measuring the vibration history along the transportation route using a container equipped with a vibration sensor. Accelerometers were attached to the bottom of the container in the three axial directions to measure the vibration histories for three truck movement paths. In ISO 19453-6, the vibration environment of road vehicles requires the use of a random vibration method. All vibration levels in the trucking section partially exceeded the vibration profile of ISO 19453-6. In conclusion, the transport vibration profile proposed in ISO 19453-6 was 69% on the x-axis, 68% on the y-axis, and 38% on the z-axis compared to the truck vibration profile.
