A protective device for a housing, such as a battery housing, is provided for discharging an overpressure from the interior of the housing. The protective device has a closure element for sealing an opening in the housing in a first operating state. The closure element is arranged to be movable relative to the housing and is configured to be moved into a second operating state in a non-destructive manner. A bearing element is provided for guiding the closure element. The closure element may have at least in some regions, a membrane having a predetermined permeability, and in the second operating state the closure element uncovers the opening in the housing.

Vehicle mounted Radio Frequency Identification (RFID) systems and associated methods are provided. An example vehicle mounted RFID system is configured to operate an RFID system in a high-power mode. The example vehicle mounted RFID system is further configured to determine that an operating state of a vehicle switched from an active charging state to an inactive state. The example vehicle mounted RFID system is further configured to, in response to determine that the operating state of the vehicle switched from the active charging state to the inactive state, initialize a timer for a period of time. The example vehicle mounted RFID system is further configured to, in response to an elapse of the period of time, switch the RFID system to a low-power mode.

A battery case of a battery storage device is disposed on a vehicle floor, thereby securing an interior space. A battery module of the battery storage device can be cooled by using an interior air, thereby simplifying a cooling structure and saving a manufacturing cost. In addition, the battery storage device for an electric vehicle blocks noise generated by a cooling device and an electrical component from flowing into the interior, thereby preventing the occurrence of a passenger's discomfort feeling caused by the noise.

A heating wire apparatus for a vehicle safety glass includes: a plurality of bus bars located at a periphery of the vehicle safety glass; a plurality of heating wires having a serial pattern between the plurality of bus bars; and a battery that applies a voltage to the plurality of heating wires.

A battery unit arrangement structure for a vehicle increases legroom for a passenger while disposing a battery in front of the passenger seat. The structure includes a dash vertical wall separating an interior from an engine compartment, a floor panel of the interior, and a curved corner portion connecting the lower end of the dash vertical wall and the front end of the floor panel together. The battery unit is mounted on the corner portion in front of the passenger seat with the upper surface of the battery unit inclined downward toward the vehicle rear so the rear end of the battery unit is lower than the front end of the battery unit. The battery unit is covered from above with a cover member inclined downward toward the vehicle rear so the rear end of the cover member is lower than the front end of the cover member.
