Abstract
A motor vehicle, particularly a passenger car, contains an onboard electrical system having a number of electrical consumers, a generator and an onboard electrical system rechargeable battery. A bidirectional interface is provided for a rechargeable device battery of a mobile device such that the rechargeable device battery can be coupled to the onboard electrical system by the bidirectional interface and, when coupled, can both be charged by the onboard electrical system and be used as an additional energy source in the onboard electrical system.
Claims20
A motor vehicle, comprising:
- an onboard electrical system having a plurality of electrical consumers, a generator and an onboard electrical system rechargeable battery;
- and
- a bidirectional interface for connecting to a device rechargeable battery of a secondary vehicle having an electric motor such that the device rechargeable battery being coupled to said onboard electrical system via said bidirectional interface, via a plug-type connector or in a contactless fashion, and in a coupled state the device rechargeable battery being charged by said onboard electrical system and, the device rechargeable battery being available as an additional energy source for said onboard electrical system, the secondary vehicle being a last-mile vehicle and the motor vehicle being configured to accommodate or carry the secondary vehicle, wherein said onboard electrical system is configured in such a way that the device rechargeable battery can be coupled to the onboard electrical system via the bidirectional interface and in the coupled state the device rechargeable battery can be used in addition to the onboard electrical system rechargeable battery as an additional energy source in the onboard electrical system, such that in some operating states the onboard electrical system rechargeable battery and the device rechargeable battery are used in parallel at the same time.
A motor vehicle system, comprising:
- a first motor vehicle containing an onboard electrical system having a plurality of electrical consumers, a generator and an onboard electrical system rechargeable battery;
- a secondary vehicle having an electric motor and a device rechargeable battery, said secondary vehicle being a last-mile vehicle and being accommodated in or carried by said first motor vehicle;
- and
- said first motor vehicle having a bidirectional interface for connecting to said device rechargeable battery of said secondary vehicle such that said device rechargeable battery being coupled to said onboard electrical system via said bidirectional interface, via a plug-type connector or in a contactless fashion, and in a coupled state said device rechargeable battery being charged by said onboard electrical system and, said device rechargeable battery being available as an additional energy source for said onboard electrical system, wherein said onboard electrical system is configured in such a way that the device rechargeable battery can be coupled to the onboard electrical system via the bidirectional interface and in the coupled state the device rechargeable battery can be used in addition to the onboard electrical system rechargeable battery as an additional energy source in the onboard electrical system, such that in some operating states the onboard electrical system rechargeable battery and the device rechargeable battery are used in parallel at the same time.
