In October 2019 , a fire followed by an explosion affected the battery compartment of the Norwegian hybrid ferry Ytterøyningen. The fire was declared under control a few hours later.
Experts are still trying to determine the initial cause of the fire. The fire is believed to have started outside the battery compartment. Other questions remain about the functioning of the battery management system, including the activation of the battery pack ventilation and whether or not explosive gases generated by a faulty battery had accumulated.
