1. An electric harness for connecting a primary electronic device to a secondary electronic device, comprising:
a main branch comprising:
a supply end for electrically connecting the electric harness to the primary electronic device;
a load end for electrically connecting the electric harness to the secondary electronic device;
an electronic current limiter configured to limit a main electric current supplied by the primary electronic device via the supply end, on the main branch, to a main current limit; and
a main one-way switch configured for passing the main electric current from the electronic current limiter to the load end; and
an auxiliary branch in parallel with the main branch and connected thereto at the supply end and the load end, the auxiliary branch comprising:
an electric energy storage device; and
an auxiliary one-way switch connecting the electric energy storage device to the load end, the auxiliary one-way switch configured to operate in:
a first mode in which the auxiliary one-way switch is open; and
a second mode in which the auxiliary one-way switch is closed allowing an auxiliary electric current supplied by the electric energy storage device to flow to the load end while blocking the main electric current from flowing through the auxiliary branch;
wherein, when the secondary electronic device draws a load current in excess of the main current limit:
the electronic current limiter limits the main electric current to the main current limit;
the auxiliary one-way switch operates in the second mode thus allowing the auxiliary electric current to flow through the auxiliary branch to the secondary electronic device; and
the main electric current and the auxiliary electric current together are equal to the load current.
