A vehicle temperature control system, for electric motor-powered vehicles or hybrid vehicles, includes a heater (18), which can be operated electrically or/and with fuel, with a first heat exchanger device (16) for transferring heat provided in the heater (18) to a first heat carrier medium provided in a first heat carrier medium circuit (12). An operating material tank (20) holds a liquid operating material (24). A second heat exchanger device (26) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and energy storage material (36) contained in the operating material tank (20). A third heat exchanger device (38) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and a second heat carrier medium provided in a second heat carrier medium circuit (40).

A fuel storage system may be configured for a vehicle and may include a fuel tank, at least one inflatable bladder extending inside the tank, and at least one heat storage member, extending inside the tank, comprising a phase change material having a melting point in a range of from 18 to 40 C. The heat storage member may be attached to a bottom wall of the tank and/or attached to the bladder. The system may include several heat storage members.

A vehicle fuel storage system may include: a fuel tank, a support member extending inside the tank, and several inflatable bladders extending inside the tank. Each of the inflatable bladders being carried by the support member and attached to the support member. Such bladders may include polyethylene and/or polyamide, or the bladders may be multilayered, including polyethylene and ethylene vinyl alcohol. Each bladder may have a maximum volume in a range of from 5 to 15 liters.
