DISCONNECTION UNIT FOR DISCONNECTING A BATTERY FROM A POWER SYSTEM AND A MOTOR VEHICLE HAVING A LITHIUM-ION BATTERY
A disconnection unit is configured for disconnecting a battery from a power system. A fuse is configured to interrupt a circuit between the battery and the power system. The fuse is integrated into the disconnection unit.
1 . A disconnection unit for disconnecting a battery from a power system, the disconnection unit comprising:
a fuse integrated into the disconnection unit, the fuse configured to interrupt an electrical circuit between the battery and the power system.
2 . The disconnection unit as claimed in claim 1 , wherein the fuse has a permanent mechanical connection by at least one of an interlocking connection and a cohesive connection configured to produce the electrical contact connection.
3 . The disconnection unit as claimed in claim 2 , wherein the interlocking connection corresponds to a screw and the cohesive connection corresponds to soldering.
4 . The disconnection unit as claimed in claim 1 , further comprising at least one contactor which is connected to the fuse.
5 . The disconnection unit as claimed in claim 4 , wherein the contactor is connected in series with the fuse.
6 . The disconnection unit as claimed in claim 1 , wherein a current path has at least one of a current sensor, a temperature sensor, a voltage sensor, and an insulation sensor.
7 . The disconnection unit as claimed in claim 1 , wherein the fuse is a high-voltage fuse.
8 . The disconnection unit as claimed in claim 1 , further comprising:
a large number of connection points,
wherein current relays are incorporated into connections between respective connection points.
9 . A battery, comprising:
a disconnection unit configured to disconnect a battery from a power system, the disconnection unit including a fuse integrated into the disconnection unit, the fuse configured to interrupt an electrical circuit between the battery and the power system.
10 . A motor vehicle, comprising:
a battery, including a disconnection unit configured to disconnect a battery from a power system, the disconnection unit including:
a fuse integrated into the disconnection unit, the fuse configured to interrupt an electrical circuit between the battery and the power system, wherein the battery is connected to a drive system of the motor vehicle.
11 . The battery as claimed in claim 9 , wherein the battery is a lithium-ion battery.
