## Abstract

An electrical power supply module intended to supply power to an on-board DC electrical network of an aircraft comprising a battery (12) including a primary line (16), a secondary line (18) and a switching member between said primary and secondary lines; and an electrical distribution box (24) separate from the battery (12) including at least one electrical power supply busbar (26) and a plurality of electrical distribution lines (28) each bearing a circuit breaker (30). The power supply module comprises a connection pad (32) positioned on the secondary power supply line (18) allowing a voltage connection between the battery (12) and the electrical distribution box (24).

## Claims

### Claim 1

An electrical power supply module intended to supply power to an on-board DC electrical network of an aircraft comprising:
a battery including a primary line, a secondary line and a switching member positioned between said primary and secondary lines; and
an electrical distribution box separate from the battery including at least one electrical power supply busbar and a plurality of electrical distribution lines each bearing a circuit breaker;
characterized in that it comprises a connection pad positioned on the secondary power supply line allowing a voltage connection between the battery and the electrical distribution box.

### Claim 2 (depends on 1)

The electrical power supply module according to claim 1, in which the battery is a battery of the lithium-ion type.

### Claim 3 (depends on 1)

The electrical power supply module according to claim 1, comprising means for fastening the electrical distribution box to a lateral face of the battery.

### Claim 4 (depends on 3)

The electrical power supply module according to claim 3, in which the fastening means are mechanical and reversible fastening means.

### Claim 5 (depends on 4)

The electrical power supply module according to claim 4, in which the fastening means are screws, nuts, and bolts or quarter-turn fasteners.

### Claim 6 (depends on 3)

The electrical power supply module according to claim 3, in which the fastening means comprise hinges positioned respectively on one side of said lateral face of the battery.

### Claim 7 (depends on 3)

The electrical power supply module according to claim 3, in which the connection pad is inserted into a through-hole made in said lateral face of the body of the battery.

### Claim 8 (depends on 1)

The electrical power supply module according to claim 1, in which the connection pad is a high-power pad.

### Claim 9 (depends on 1)

The electrical power supply module according to claim 1, in which the electrical distribution box takes the form of a parallelepipedal panel, the height (H) and/or width (L) of which are substantially identical to the height and/or width of the battery, respectively.

### Claim 10 (depends on 1)

The electrical power supply module according to claim 1, in which the battery comprises output terminals connected to the primary power supply line.
