Battery system with elastic hose
A battery system having a hose made from an elastic material. The hose is designed to be fitted on a hose connection by pushing a hose endpiece of the hose over the hose connection. The hose endpiece is designed to be fastened on the hose connection by a hose clip that is arranged in a fitting region of the hose endpiece. The hose endpiece has at least one thickened area which protrudes from the outer side of the hose. The thickened area protrudes from the outer side of the hose to such an extent that a hose clip suitable for fastening the hose on the hose connection is held on the hose endpiece by the thickened area with respect to the influence of gravity in the longitudinal direction of the hose endpiece. The hose may have multiple branch-off points.

a first clip configured to maintain a coupling between the first end piece and the first hose connector, wherein the protrusion of the first end piece is configured to retain the first clip on the first end piece;
a second clip configured to maintain a coupling between the second end piece and the second hose connector, wherein the protrusion of the second end piece is configured to retain the second clip on the second end piece; and
an additional battery cooling hose comprising:
an additional first end piece disposed at an additional first branch-off point of the additional battery cooling hose and configured to fluidly couple the additional battery cooling hose with the first battery element; and
an additional second end piece disposed at an additional second branch-off point of the additional battery cooling hose and configured to fluidly couple the additional battery cooling hose with the second battery element, an additional first hose connector is configured to couple between the additional first end piece and the first battery element, an additional second hose connector is configured to couple between the additional second end piece and the second battery element; and
the battery cooling hose is configured to be an inlet manifold to the first and second battery elements, and the additional battery cooling hose is configured to be an outlet header of the first and second battery elements.
2. The battery system of claim 1 , wherein the first battery element comprises the first hose connector, and wherein the second battery element comprises the second hose connector.
3. The battery system of claim 1 , wherein the protrusion of the first end piece comprises an outermost diameter greater than an inner diameter of the first clip.
4. The battery system of claim 1 , wherein the first clip comprises an inner diameter that is adjustable.
5. The battery system of claim 4 , wherein the first clip comprises a crimping region that, when crimped, is configured to reduce the inner diameter of the first clip such that an inner surface of the first clip comprising the inner diameter exerts a compressive force against the outer surface of the main body of the first end piece, wherein the compressive force is configured to maintain the coupling between the first end piece and the first hose connector.
6. The battery system of claim 1 , wherein the protrusion of the first end piece is tapered outwardly from an end face of the first end piece toward the first branch-off point such that the protrusion of the first end piece comprises a diameter that tapers down toward the end face of the first end piece.
7. The battery system of claim 1 , wherein the protrusion of the first end piece is circumferentially segmented into a first portion and a second portion disposed on opposing sides of the first end piece.
8. The battery system of claim 1 , wherein the first end piece comprises an additional protrusion disposed longitudinally adjacent the protrusion of the first end piece with respect to a longitudinal axis of the first end piece, wherein the protrusion of the first end piece and the additional protrusion of the first end piece are separated by an assembly region of the first end piece, and wherein the assembly region of the first end piece is configured to receive the first clip.
9. The battery system of claim 1 , wherein the battery cooling hose comprises an inner surface having an elastic material configured to directly contact a coolant of the battery system.
10. The battery system of claim 1 , wherein the battery cooling hose comprises an elastic material.
11. The battery system of claim 1 , comprising a coolant source configured to supply a coolant to the battery cooling hose, wherein the battery cooling hose is configured to supply the coolant to the first end piece and the second end piece, wherein the first end piece is configured to supply the coolant to the first battery element via the first hose connector, and wherein the second end piece is configured to supply the coolant to the second battery element via the second hose connector.
12. The battery system of claim 1 , comprising an electronic control unit that:
receives data indicative of a first temperature of the first battery element, of a second temperature of the second battery element, or both; and
controls, based on the data, a flow of coolant toward the first battery element, toward the second battery element, or both.
