A storage tank for storing a liquid comprises a main storage chamber; an internal sub chamber located within the storage tank; and a reclosable filling opening for enabling filling of liquid into the main storage chamber and internal sub chamber. An overflow level of the internal sub chamber is located substantially at or above a predetermined fill level of the main storage chamber. The reclosable filling opening and the internal sub chamber are arranged in a substantially superposed relationship in a vertical direction, such that a substantially or entirely vertical stream of liquid filling the storage tank via the reclosable filling opening is configured to enter the internal sub chamber. A method for filling a storage tank with a liquid, a method for manufacturing a storage tank for storing a liquid, and a system comprising a storage tank and a filling nozzle are also described.

1. A storage tank for storing a liquid, wherein the storage tank comprises: a main storage chamber;an internal sub chamber located within the storage tank;a reclosable filling opening for enabling filling of liquid into the main storage chamber and internal sub chamber; andan inlet/outlet located in an exterior wall of the main storage chamber and being configured to be connected to a cooling circuit of a liquid cooling system;wherein an overflow level of the internal sub chamber is located substantially at or above a predetermined fill level of the main storage chamber, andwherein the reclosable filling opening and the internal sub chamber are arranged in a substantially superposed relationship in a vertical direction, such that a substantially or entirely vertical stream of liquid filling the storage tank via the reclosable filling opening is configured to enter the internal sub chamber before overflowing into the main storage chamber. 2. The storage tank according to claim 1, wherein the predetermined fill level of the main storage chamber is indicated on the storage tank by means of at least one fill level marking. 3. The storage tank according to claim 2, wherein the at least one fill level marking includes an upper fill level marking indicating a first fill level and a lower fill level marking indicating a second fill level, wherein the first fill level corresponds to a larger filling volume than the second fill level, and wherein an overflow level of the internal sub chamber is located at or above the lower fill level marking. 4. The storage tank according to claim 1, wherein the storage tank comprises a fill level sensor located within the main storage chamber, and wherein the predetermined fill level of the main storage chamber is indicated by means of the fill level sensor. 5. The storage tank according to claim 1, wherein the storage tank is configured such that liquid will flow from the internal sub chamber to the main storage chamber upon overflow of the internal sub chamber. 6. The storage tank according to claim 1, wherein the internal sub chamber has a storage capacity in the range of 1 to 100 milliliters. 7. The storage tank according to claim 1, wherein the storage tank comprises an exterior wall that defines the main storage chamber, and wherein the internal sub chamber is displaced from the exterior wall on all sides thereof. 8. The storage tank according to claim 1, wherein the storage tank comprises an exterior wall that partly defines the main storage chamber and partly defines the internal sub chamber. 9. The storage tank according to claim 1, wherein an internal partition wall within the storage tank divides the main storage chamber from the internal sub chamber. 10. The storage tank according to claim 1, wherein the internal sub chamber is defined by a hollow rigid body with an open upper end and a closed lower end, and the internal sub chamber is formed between the upper and lower ends. 11. The storage tank according to claim 10, wherein the storage tank comprises an upper injection moulded tank element having a closed end and an open end and a lower injection moulded tank element having a closed end and an open end, wherein the upper and lower tank elements are permanently connected to each other with their open ends facing each other such as to form a single piece storage tank, wherein the hollow rigid body is integrally formed with the upper tank element. 12. The storage tank according to claim 10, wherein the open end of the upper tank element is oriented in a direction opposite a direction of orientation of the open upper end of the hollow rigid body. 13. The storage tank according to claim 1, wherein the storage tank is an expansion tank for storing a cooling liquid of a liquid cooling system. 14. A system comprising-a storage tank according to claim 1 and a filling nozzle for filling the storage tank with a liquid, wherein the filling nozzle comprises: an abutment surface for abutting the reclosable filling opening of the storage tank, anda spout with an opening for filling liquid into the storage tank and sucking out superfluous liquid from the storage tank,wherein the opening of the filling nozzle is located within the internal sub chamber when the filling nozzle is sealingly inserted into the reclosable filling opening and the abutment surface abuts the reclosable filling opening. 15. A system comprising: a storage tank comprising: a main storage chamber;an internal sub chamber located within the storage tank; anda reclosable filling opening for enabling filling of liquid into the main storage chamber and internal sub chamber;wherein an overflow level of the internal sub chamber is located substantially at or above a predetermined fill level of the main storage chamber;wherein the reclosable filling opening and the internal sub chamber are arranged in a substantially superposed relationship in a vertical direction, such that a substantially or entirely vertical stream of liquid filling the storage tank via the reclosable filling opening is configured to enter the internal sub chamber; anda filling nozzle comprising: an abutment surface for abutting the reclosable filling opening of the storage tank, anda spout with an opening for filling liquid into the storage tank and extracting superfluous liquid from the storage tank,wherein the opening of the filling nozzle is located within the internal sub chamber when the filling nozzle is inserted into the reclosable filling opening and the abutment surface abuts the reclosable filling opening. 16. The system according to claim 15, wherein the storage tank comprises an exterior wall that defines the main storage chamber, and wherein the internal sub chamber is displaced from the exterior wall on all sides thereof. 17. The system according to claim 15, wherein the storage tank comprises an exterior wall that partly defines the main storage chamber and partly defines the internal sub chamber. 18. The system according to claim 15, wherein the storage tank is configured such that, after the main storage chamber and internal sub chamber have been completely filled with the liquid, excess liquid may be extracted via a filling nozzle extended into the internal sub chamber of the storage tank such that once the fill level of the excess liquid within the main storage chamber is reduced to the overflow level of the internal sub chamber, the excess liquid within the internal sub chamber will be extracted. 19. The storage tank according to claim 1, wherein the storage tank is configured such that, after the main storage chamber and internal sub chamber have been completely filled with the liquid, excess liquid may be extracted via a filling nozzle extended into the internal sub chamber of the storage tank such that once the fill level of the excess liquid within the main storage chamber is reduced to the overflow level of the internal sub chamber, the excess liquid within the internal sub chamber will be extracted. 20.
