A cooling arrangement for cooling components of a heavy-duty electric or hybrid electric vehicle, the cooling arrangement comprising a fan, a mount, an axial flux electric motor, and a control unit arranged to control the cooling arrangement. The control unit is configured to obtain a predicted cooling requirement of the vehicle for a future time by obtaining information about a speed of the vehicle at a future time and using a heat estimation model to estimate an amount of heat generated at the future time based on the speed of the vehicle, and/or obtaining information about a characteristic of a path of the vehicle at the future time and using the heat estimation model to estimate the amount of heat generated at the future time based on the characteristic of the path of the vehicle.

The control apparatus includes a heater configured to generate heat to heat the internal combustion engine, a controller configured to control a heat exchange system in such a way as to transfer EV exhaust heat to the internal combustion engine, and an controller configured to let electrical power be supplied from a battery to the heater before the internal combustion engine is started if it is predicted that a specific warmed-up condition of the internal combustion engine will not be established before the start of the internal combustion engine and not to let electrical power be supplied from a battery to the heating if it is predicted that a specific warmed-up condition of the internal combustion engine will be established before the start of the internal combustion engine.

A cooling device for a vehicle is provided, which includes a first coolant channel through which a first coolant for cooling an engine flows, a second coolant channel through which a second coolant for cooling a motor drive flows, and an oil channel through which oil for lubricating inside a transmission flows. The oil channel includes a first heat exchanger configured to exchange heat between the first coolant and the oil, a second heat exchanger configured to exchange heat between the second coolant and the oil, and a valve configured to adjust a first flow rate of the oil circulating through the first heat exchanger and a second flow rate of the oil circulating through the second heat exchanger.

A hybrid vehicle having an electric drive with an energy storage device for the electric drive, and an internal combustion engine, and a tank device having a tank for storing fuel for the internal combustion engine. The hybrid vehicle further includes a cooling circuit, extending through the tank, having a circulating cooling medium to cool the energy storage device and also cool the fuel in the tank.

Disclosed are an apparatus and method for controlling an oil pump for a vehicle which may control the speed of the oil pump. The apparatus includes a controller configured to control the speed of the oil pump based on the temperature information of a motor and oil and the speed and torque information of the motor, and, when the vehicle is being driven, the controller confirms whether or not a motor or oil temperature is higher than or equal to a first set temperature, controls the speed of the oil pump to a maximum speed value when the motor or oil temperature is higher than or equal to the first set temperature, and calculates a control speed value and controls the speed of the oil pump to the calculated control speed value when the motor or oil temperature is lower than the first set temperature.

The present invention provides a battery temperature control system having a simple configuration and capable of immediately raising a battery temperature by actively using heat generated by an internal combustion engine. The battery temperature control system includes: an engine cooling circuit in which a coolant in an internal combustion engine is circulated between a coolant jacket and a radiator by a coolant pump; an exhaust heat recovery circuit in which a coolant in an EGR cooler that recovers exhaust heat of the internal combustion engine flows; a battery cooler-destined branch circuit that is branched from the engine cooling circuit and goes toward an upstream side of the battery cooler in the battery cooling circuit 11; and a channel switching mechanism that selectively connects a downstream side of at least one of the exhaust heat recovery circuit or the battery cooler-destined branch circuit to the upstream side of the battery cooler in the battery cooling circuit.

A cooling arrangement for a vehicle includes a bottle having a first expansion tank for a coolant and a second expansion tank for a coolant, and a cap which is connectable to and disconnectable from the bottle for covering a mouth of the bottle. The mouth having a filling port of the first expansion tank and a filling port of the second expansion tank which both are covered by the cap when the cap is connected to the bottle. The cap is provided with a first pressure relief valve allowing fluid to be discharged from the first expansion tank through the first expansion tank filling port to the atmosphere, and a second pressure relief valve allowing fluid to be discharged from the second expansion tank through the second expansion tank filling port to the atmosphere.

The invention relates to a cooling module for an electric or hybrid vehicle, the cooling module having a housing including an air inlet and an air outlet and within which there are arranged an assembly of heat exchangers and a tangential turbomachine configured so as to generate an air flow passing through the housing from its air inlet to its air outlet and passing through the assembly of heat exchangers. The housing has, on one of its outer lateral faces, a two-fluid heat exchanger in order to allow the exchanges of heat energy between a first heat-transfer fluid circulating in a first circulation loop and a second heat-transfer fluid circulating in a second circulation loop.

Disclosed is a cooling system comprising: a first cooling circuit with a first coolant pump; a second cooling circuit with a second coolant pump; an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and a deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating therein. The deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a static line to allow air bubbles separated from the coolant in the deaeration device to migrate upwards in the static line towards the expansion chamber.

A reservoir tank includes first and second chambers separated by partitions. The first chamber is configured such that coolant circulates through the first chamber. The second chamber is provided on a side and spaced apart from the first chamber and is configured such that coolant having a different temperature from the coolant stored in the first chamber circulates through the second chamber. A first partition and a second partition are provided so as to separate the first chamber and the second chamber from each other, and are spaced apart from and facing each other. A middle chamber is defined in a space between the first partition and the second partition and configured such that the coolant from the first chamber or the second chamber circulates through the middle chamber, thereby providing a heat buffer between the first chamber and the second chamber.
