## Abstract

An electronic system housing for an E-axle drive of a motor vehicle is disclosed. The electronic system housing comprises a power electronic system received within the electronic system housing for processing voltage in high voltage systems. At least one low voltage component is further received within the electronic system housing.

## Claims

### Claim 1

An electronic system housing for an E-axle drive of a motor vehicle, comprising:
a power electronic system disposed within the electronic system housing; and
at least one low voltage component mounted directly on the electronic system housing, wherein the low voltage component is one of a motor sensor arrangement, a temperature sensor, a parking brake actuator system and a transmission actuator system,
wherein the electronic system housing is arranged adjacent, and connected, to an overall housing, the overall housing being arranged to receive an electric machine,
wherein an opening extends through a portion of the electronic system housing and the low voltage component includes a protrusion extending through the opening when mounted on the electronic system housing.

### Claim 2 (depends on 1)

The electronic system housing as claimed in claim 1, wherein the low voltage component further comprises at least one interface for an actuator.

### Claim 3 (depends on 1)

The electronic system housing as claimed in claim 1, wherein the electronic system housing and the overall housing include interfaces that engage with one another, wherein the interfaces are arranged to be pressed together in a positive-locking manner.

### Claim 4 (depends on 1)

The electronic system housing as claimed in claim 1, wherein the electronic system housing is arranged below the overall housing.

### Claim 5 (depends on 1)

The electronic system housing as claimed in claim 1, wherein at least one cooling connector is provided on the electronic system housing.

### Claim 6 (depends on 1)

The electronic system housing as claimed in claim 1, wherein an intermediate element is arranged between the electronic system housing and the overall housing.

### Claim 7 (depends on 1)

The electronic system housing of claim 1, wherein the power electronic system is configured to process voltage in a 48 volt voltage system.

### Claim 8 (depends on 1)

The electronic system housing of claim 1, further comprising a seal disposed on an outer surface of the protrusion, wherein the seal is configured to seal the low voltage component to the electronic system housing.
