[0021] By way of non-limiting introduction and overview, in various embodiments, an apparatus includes a wireless transmission unit electrically coupled to a high voltage system of a vehicle and configured to enable wireless bidirectional power exchange between the high voltage system and an auxiliary device. The high voltage system is operable to power a drive train of the vehicle. The auxiliary device is separate from the vehicle and configured to perform at least one of: providing power to the high voltage system, and receiving power from the high voltage system.

[0022] Now that an overview has been given, details of various embodiments will be explained by way of non-limiting examples given by way of illustration only and not limitation.

[0023] The following description explains, by way of illustration only and not limitation, various embodiments of vehicles, devices, and methods for assisting an operator in benefiting from identifying alternative routes of travel.

[0024] See also Figure 1, a vehicle 100 (which may be a passenger car, truck, sport utility vehicle (SUV), or other vehicle) includes a body 102 that houses the vehicle's onboard systems. The body 102 also includes a cabin 104 to accommodate an operator and possibly one or more passengers. The body 102 also includes a cargo area 106, such as a trunk or truck bed. Among the onboard systems, the vehicle 100 includes a transmission system 101 that provides power to wheels 103 to propel the vehicle 100. In various embodiments, the vehicle 100 is an electric vehicle that includes a high voltage system 105 that provides electricity capable of powering the transmission system 101. It should be understood that an electric vehicle or hybrid vehicle uses more electricity than, for example, a gasoline-powered vehicle that relies primarily on internal combustion to power its transmission system.

[0025] In various embodiments, one or more wireless transmission units 110 and 112 are positioned around the body 102 of the vehicle 100 to provide power transmission between the high voltage system 110 and one or more auxiliary devices 111 and 113. The wireless transmission units 110 and 112 are bidirectional and are therefore configured to transmit power to or from the high voltage system 105. In various embodiments, the wireless transmission units 110 and 112 use inductive power transmission to transmit power between the high voltage power system 110 and the auxiliary devices 111 and 113, as further described below. Therefore, when the auxiliary devices 111 and 113 are placed adjacent to the wireless transmission units 110 and 112, respectively, the inductive power transmission allows power to be wirelessly transmitted between them. In various embodiments, the wireless transmission units 110 and 112 communicate with a transmission control unit 120, which implements control of power transmission between the wireless transmission units 110 and 112 and the auxiliary devices 111 and 113, as further described below. In various embodiments, the wireless transmission units 110 and 112 are coupled to the high voltage system 105 directly or through a transmission control unit 120 .

[0026] In various embodiments, one or more wireless transmission units 110 and 112 are located in the cabin 104 and / or the cargo area 106 of the vehicle 100. The wireless transmission unit 110 disposed in the cabin 104 may be located, for example, on the floor of the cabin 104. Thus, the auxiliary device 111 may be located on the floor adjacent to the wireless transmission unit 110 to exchange power with the high voltage system 105. When located on the floor, the wireless transmission unit 110 and the auxiliary device 111 may transmit power without excessively occupying space and thereby interfering with the comfort of one or more occupants of the cabin 104.

The auxiliary device brackets 402 and 404 may position the auxiliary device near the wireless transmission unit 401 and 403. The close positioning of the auxiliary device and the wireless transmission unit 401 and 403 may help keep the auxiliary device near the wireless transmission unit 401 and 403 to facilitate the inductive transfer of power therewith. Having auxiliary device brackets 402 and 404 may be particularly helpful in moving the vehicle to prevent the auxiliary device from sliding or otherwise moving away from the wireless transmission unit 401 and 403, thereby reducing the effectiveness of the wireless power transfer.

[0038] See also Figure 4A In various embodiments, the wireless transmission unit 401 is configured to exchange power with an auxiliary transmission unit 311 of the auxiliary device 301 (or an external auxiliary transmission unit 312 of the auxiliary device 302), which is configured to wirelessly exchange power through the bottom surface of the auxiliary device 301.
