Abstract
A gas pressure tank system is disclosed, and includes at least one gas pressure tank comprising a thermal pressure relief device. The thermal pressure relief device may include a valve unit fluidically connected to the at least one gas pressure tank and including at least one fluid path, by way of which a gas stored in the at least one gas pressure tank can be discharged into an environment. The valve unit may include a locking element which can be moved between an open position, in which the gas can flow through the fluid path, and a closed position, in which no gas can flow through the fluid path. The thermal pressure relief device may include a first trigger means configured to detect heat impact at least at one location of the gas pressure tank system spatially separated from the installation location of the thermal pressure relief device.
