Embodiment Construction

[0047] To illustrate the prior art, it has been referred to figure 1 and figure 2 .

[0048] Refer to attached image 3 To illustrate the present invention. compared to in figure 1 and figure 2 In the conventional power supply shown in , the power supply according to the invention has a second electrical line 20 in which an overcurrent protection device 21 is arranged. The overcurrent protection device 21 is connected in series with the disconnect switch 13, wherein the disconnect switch 13 is electrically operable. That is to say the disconnect switch 13 is only closed when it is powered. Thus, when the overcurrent protection device 21 in the second electrical conductor 20 is triggered, the current in the second electrical conductor 20 will be interrupted and no power will be supplied to the disconnect switch 13, causing it to open. The first electrical line 10 and thus decouples the battery 1 from the power grid.

[0049] The power supply device according to the in...

Abstract

The invention relates to a power supply device, comprising a first electric line (10) and at least one battery (1) connected thereto, in particular a lithium-ion battery, and an electrically operable circuit breaker (13) arranged in the first electric line (10) for interrupting a current flow in the first electric line (10). The power supply device further comprises a second electric line (20) for supplying power to the circuit breaker (13), wherein in the second electric line (20) an overcurrent protection device (21) is arranged, by means of which a current flow in the second electric line (20) can be interrupted and thus the circuit breaker (13) can be controlled in such a manner that same interrupts the current flow in the first electric line (10).; The invention further relates to a method for disconnecting a battery (1), in particular a lithium-ion battery, from a connection device coupled to the battery (1) via a first electric line (10), and to a motor vehicle having the power supply device according to the invention.

Description

technical field [0001] The invention relates to a power supply device comprising a first electrical conductor and at least one accumulator connected thereto, as well as an electrically operable disconnect switch arranged in the first electrical conductor for disconnecting the current in the first electrical conductor . [0002] Furthermore, the invention relates to a connection for coupling to an accumulator via a first electrical line by means of an electrically operable disconnect switch arranged in the first electrical line for breaking the current in the first electrical line. A method of separating the storage battery from the device. [0003] Furthermore, the invention relates to a motor vehicle having a power supply device according to the invention. Background technique [0004] Especially when lithium-ion batteries are used in motor vehicles, the entire on-board electrical system of the motor vehicle needs to be switched voltage-free for maintenance and / or repair ...
