MOTOR VEHICLE DRIVE UNIT INCLUDING A FUEL CELL AND AN ENERGY STORAGE SYSTEM

摘要

The invention concerns a motor vehicle drive unit, comprising: a fuel cell (3) comprising a flat nonlinear control whereof control input Ppac* is a setpoint of the electrical power to be delivered by the fuel cell; a reversible electrical energy storage system (2); an electric motor (4); an electrical connection element (11) configured to selectively connect the fuel cell and/or the energy storage system to the electric motor (4); a control circuit (5, 31): - memorising a model of the dihydrogen consumption of the fuel cell on the basis of the electrical power delivered by said fuel cell g(Ppac*) = a*Ppac*2 + b*Ppac* + c; - configured to calculate a coefficient of power distribution between the fuel cell and the storage system: formula (K) - configured to apply power setpoint Ppac*, where Ppac*=(λ1-b)/(2a).
