An arrangement for a vehicle includes a fuel cell, an electric traction and/or propulsion motor, and a single cooling circuit cooling the fuel cell and the electric motor. The cooling circuit includes two parts: a first, high-flowrate and high-temperature part including a high-temperature exchanger and a second, low-flowrate and low-temperature part including a low-temperature exchanger. The first part cools the fuel cell and the second part cools the electric motor. The first part includes a high-flowrate pump, in particular for a high flowrate of between 8000 l/h and 9000 l/h and the second part includes a low-flowrate pump, in particular for a low flowrate of between 2000 l/h and 3000 l/h.

A device for the thermal management of a power train includes a main housing accommodating an electric motor and its cooling circuit and a speed reducer including a lubrication circuit. The main housing includes an oil sump arranged in the lower part of the main housing and a partition separating same into two parts, wherein there are arranged respectively, on the one hand, the motor and its cooling circuit, and on the other hand, the speed reducer and its lubrication circuit, while an oil channel extends in the oil sump through the partition in order to bring the two parts into communication and includes one end on the speed reducer side provided with a valve for regulating the oil flow, controlled by the oil temperature, so as to close the oil passage in the oil channel when the oil temperature on the speed reducer side reaches a predetermined temperature threshold.

Device for the thermal management of an electric power train

A cooling system for a hybrid powertrain of a motor vehicle comprising an internal combustion engine and an electric traction assembly, comprising a main circuit that can be traversed by a coolant in order to cool the internal combustion engine to a first temperature level and a secondary circuit that can be traversed by a coolant to cool the electric traction assembly to a second temperature level, lower than the first level, each of the circuits and comprising a radiator capable of cooling the coolant by means of heat exchange with an air flow, at least one hydraulic pump for circulating the coolant in the coolant circuits, and one electronic control unit capable of controlling the hydraulic pumps. The control unit comprises a module for recovering information on the dynamics of the vehicle and a module for controlling the flow from the hydraulic pumps on the basis of that information.

Cooling system and method for a hybrid powertrain of a motor vehicle

An automobile including an electric motor, a passenger compartment, an electronic power circuit, and a cooling circuit for the electronic power circuit, in which a coolant flows and which includes: a heat exchanger configured to discharge calories carried by the coolant to outside of the vehicle; a heating radiator provided upstream from the exchanger and configured to transfer the calories carried by the coolant to air in the passenger compartment; and an adiabatic tank configured to store at least a fraction of the coolant flowing in the cooling circuit.

A device for cooling a battery or batteries of a motor vehicle, for example an electric vehicle, includes a temperature regulating unit including an evaporator that is used to cool the passenger compartment of the vehicle and arranged in a housing, the battery or batteries being contained in a case. The housing of the evaporator is connected to a conduit, an outlet of which is oriented towards a heat exchange area on at least one outer surface of the case containing the battery or batteries.

A method for controlling a vehicle drive train, which communicates or maintains in communication via at least one valve two cooling circuits operating normally and respectively associated with a heat engine and with at least one electrical member.

Method for controlling a vehicle drive train comprising two cooling circuits

An electric generator for a motor vehicle, including: a reformer for producing a reformate from a primary fuel, water and air; circuits supplying the reformer with primary fuel, air, and water; a fuel cell for production electric power from the reformate and air; a compressor for compressing the air for the fuel cell and/or the reformer; and circuits for supplying the fuel cell with reformate and air, connecting the fuel cell to the reformer and the compressor, respectively. The circuits supplying water to the reformer include a first heat exchanger for establishing heat exchange relationship between the water and the air compressed by the compressor.
