1. A method for determining a state of a battery system included in a vehicle comprising: receiving a voltage signal from a pressure-sensitive material located proximate to a component of the battery system, the voltage signal being related to a pressure applied to the pressure-sensitive material by the battery system component; comparing the received voltage signal with a threshold voltage signal; determining a state of the battery system based on a result of the comparison; and implementing at least one action associated with the state in response to the determination.
