Definitions

• the present invention relates to the regulation of the state of charge of a vehicle energy storage means, and is particularly applicable to vehicles with a heat engine and an electric machine can provide a couple participating in the training of the vehicle, especially during the start-up phase or restart.
• the - or sometimes the - electric machine of the vehicle is obviously a large energy consumer that it is important to produce and store when the vehicle only works or at least essentially thanks to the engine.
• the storage of electrical energy is obtained by means of one or more batteries, recharged by a generator driven by the engine. It is also known to store the kinetic energy of the vehicle by means of supercapacities.
• the object of the present invention is thus to provide an improvement to the management systems of the energy storage means for optimizing the consumption gain.
• this object is achieved by a method of controlling the charge of an energy storage means for powering an electric machine of a vehicle also equipped with a heat engine, comprising a regulating the load demand to be stored to allow a limitation of the load demand according to at least one dynamic parameter of the vehicle state indicative of a recoverable energy potential in the future conditions of driving the vehicle.
• the dynamic parameter is selected from the vehicle speed, the engine speed, the gear engaged and the type of driving.
• the limitation of the load demand is only allowed if the health status of the energy storage means is estimated to be undegraded, this state of health being able to be deduced, for example, from the history of currents / voltages and temperatures. It is also advantageous to allow this regulation of the load demand only if the vehicle is operating normally, therefore excluding a limitation if it is considered to operate in degraded mode (for example if the engine speed is capped by failure or malfunction of certain equipment.
• the invention is in the context of vehicle architectures equipped with at least one onboard electrical power source. Depending on the various vehicle life phases (accelerations, decelerations, stop, stabilized, start, etc.), it solicits more or less the storer of electrical energy to store or restore electrical energy.
• the invention is based on a strategy for optimizing the management of the available electrical energy of a means for storing electrical energy in its various life phases as a function of vehicle parameters to optimize the consumption gain. and the ease of use while ensuring the vehicle functions.
• the deceleration that will follow before going through a complete stop state of the vehicle will recover energy to find the initial state of charge of the storer.
• the invention can be implemented with energy storage means such as conventional lead-acid batteries, NiMH (Nickel Metal Hydride) batteries, or lithium batteries. It is important, however, that the storage means is compatible with many charging and discharging cycles, which in particular directs the choice towards so-called sealed batteries.
• the invention can also be implemented with a storage means constituted by a supercapacity, for example of about 50KJ for a mid-range vehicle, as described for example in the French patent application FR 2842144 whose content is hereby incorporated by reference.
• the max and min load difference determines the limits in which the strategy is active and represents the maximum potential of available energy.
• the computer hosting the electrical management strategy retrieves the vehicle speed information.
• the said strategy can be activated beyond a certain threshold of vehicle speed.
• the following parameters enable the strategy:
• the engine speed The electrical generator of the electrical energy is linked to the engine, it must be ensured that the regime allows to ensure the recovery of energy allowing to return to an initial or minimum storage level to ensure a restart function for example
• the state of charge of the storer makes it possible to fix the phase of life of the storer (regulation, recharge or discharge) and a reference of state of charge relevant according to the parameters quoted above
• the computer can identify a type of rolling and thus identify a strategy adapted to the user.
• the strategy will focus on the energy recovery mode for a driver who will make short deceleration through the intensive use of brakes while we can better exploit the range of electrical energy available from the electric storage during a more flexible rolling ...
