Abstract: Amplifiers with temperature-adaptive gain and peaking gain control are described. In one example, a temperature-adaptive amplifier includes an amplifier, a temperature sense circuit, and a peaking control level shifter to bias shift the output of the amplifier and adjust a peaking gain of the amplifier based on the temperature control signal. The peaking control level shifter can adjust a peaking gain of the amplifier based on the temperature control signal. The temperature-adaptive control can help to compensate for peaking gain in amplifiers based on the operating temperature of the amplifier. The control can help to compensate for unwanted changes in amplifier peaking gain, over time, resulting in more consistent peaking gain over the full operating frequency range of amplifiers.

Abstract: A method and system for charging high voltage battery packs includes connecting a charger to a power source, connecting the charger to a battery pack, connecting a computer to a battery energy control module of the battery pack and charging the battery pack from the power source through the charger by running a software program on the computer and a system for conducting the method.

Abstract: A temperature monitoring vehicle charger cord assembly includes a wall plug; a pair of power prongs carried by the wall plug; at least one thermal sensor carried by the wall plug, the at least one thermal sensor adapted to monitor a charging temperature; a battery electric vehicle electrical plug; and a microprocessor electrically interfacing with the power prongs, the at least one thermal sensor and the battery electric vehicle electrical plug. The microprocessor is programmed to perform at least one of terminating electrical current and reducing amperes of electrical current flowing from the pair of power prongs to the battery electric vehicle electrical plug if the charging temperature at least meets a predetermined maximum threshold charging temperature. A temperature monitoring vehicle charging method is also disclosed.

Abstract: A vehicle includes a climate control system configured to regulate temperature within a cabin. The vehicle also includes a battery compartment disposed within the trunk, and a soft trim component that at least partially defines space within the trunk of the vehicle. The vehicle is further provided with a rigid insulative material formed upon and supporting a section of the soft trim such that the insulative material and section define a duct fluidly connecting the cabin and battery compartment in order to cool the battery compartment.

Abstract: The present disclosure relates to a vehicle battery pack cooling system, including: a housing; a fan attached to the housing; a first section of the housing including a battery module selectively in fluid communication with the fan; a second section of the housing including a battery support device selectively in fluid communication with the fan; and a baffler assembly configured to control fluid communication between the fan and the first and second sections.

Abstract: A portable high voltage charging apparatus (HVCA) can be configured to controllably charge a hybrid electric vehicle (HEV) traction battery using energy provided by a low voltage (LV) lead acid vehicle battery. An HVCA can include a DCDC converter configured to boost a lower input voltage from the LV battery to a higher output voltage provided to the HV battery. The HVCA can be configured with a traction battery interlock, allowing offline charging of the traction battery. In an example embodiment, an HVCA can be configured to communicate with an HV battery control module via a CAN bus. An HVCA can be configured to transfer energy to the HV battery for a predetermined time period, then automatically stop the transfer process. An HVCA can be configured to receive user input to start and/or stop a charging process. An example embodiment can include a supplemental charger to boost LV battery voltage.
