In response to receiving information regarding an unsafe condition from portable electrical energy storage device (e.g., battery) safety sensors, a locking mechanism controller determines whether the battery is in a desired state to, as a safety measure, have the compartment that holds the battery locked and/or to send a signal to reduce or eliminate current draw from the battery. If the locking mechanism controller determines the battery is in the desired state to have the compartment locked, then it sends a signal to a compartment locking mechanism causing the compartment locking mechanism to lock the compartment in which the battery is located to prevent a user from opening the compartment, and thus helps protect the user against the unsafe condition. In some embodiments, the unsafe condition may be a potential or existing catastrophic failure of the battery in the compartment (e.g., a meltdown, explosion or dangerous leak, etc.).
