This disclosure is directed to supercapacitor systems for supporting relatively high power transient electrical loads within vehicles. An exemplary supercapacitor system includes a mounting assembly and a supercapacitor housed within the mounting assembly. The mounting assembly may be employed to mount the supercapacitor system within a vehicle, such as within a cowl assembly or cargo space of the vehicle. The mounting assembly may include multiple panels. At least one of the multiple panels may be made of a thermally conductive polymer, and at least one other panel of the multiple panels may be made of a polymer that is reinforced by a structural foam.

A power supply switching control system switches a power supply for supplying power to a load between a first power supply and a second power supply in a power supply system. The power supply switching control system includes a first switch provided between the first power supply and the load in the power supply path and configured to cut off a current flowing from the second power supply to the first power supply in an off state of the first switch, a second switch provided between the second power supply and the load in the power supply path and configured to cut off a current flowing from the first power supply to the second power supply in an off state of the second switch, and a control unit configured to set the second switch in an on state when the second power supply is charged.

A current-averaging audio amplifier for vehicles. The current averaging audio amplifier is connectable to a DC power source and a load, and may generally comprise a power input to receive a DC electrical power from the DC power source. The system may further include a voltage converter, such as a boost converter, connected to the power input, such that the voltage converter can receive electrical power from the DC power source. The system also includes a rechargeable battery coupled to the voltage converter, such that the voltage converter charges the rechargeable battery. An audio amplifier can be powered by the rechargeable battery and connectable to supply power to the load, wherein the average power supplied by the rechargeable battery to the audio amplifier in a finite time interval differs from the average power supplied by the DC power source to the voltage converter.

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.
