Method and Device for Determining Voltages and/or Powers Available in an Electrical Recharging Network

A device for determining voltages and/or power available in an electrical recharging network, said electrical network comprising at least one voltage generator and at least two dipoles, including at least one recharging terminal i corresponding, at a first instant t1, to a pre-determined reference impedance zii, wherein said device comprises:

• a module which estimates a changing of said reference impedance zii into a modified impedance z′ii,
• a module which updates a voltage of said recharging terminal i, said updating implementing a step of determining a modified inverted loop impedance matrix Zloop_M−1 as a function of a reference inverted loop impedance matrix Zloop_R−1 and at least as a function of a difference in impedance between said modified impedance z′ii and said reference impedance zii, delivering a modified voltage U′i for said recharging terminal i,
• a module which verifies and/or updates a value of power, called available power Pdisp_i, capable of being delivered by said recharging terminal i as a function of said modified voltage U′i, of a maximum power provided by said voltage generator and/or of a threshold voltage of said electrical network delivering, in case of updating, an updated available power,
• said modules which estimate, update a voltage and verify and/or update a value of power being activated successfully at at least one second instant t2 for at least said recharging terminal i.

A non-transitory computer-readable medium comprising a computer program stored thereon comprising instructions to implement a method of determining voltages and/or power available in an electrical recharging network, when this program is executed by a processor, wherein the electrical network comprises at least one voltage generator and at least two dipoles, including at least one recharging terminal i corresponding, at a first instant t1, to a predetermined reference impedance zii, and wherein the method comprises:

• at at least one second instant t2, implementing at least one iteration of the following successive steps for at least said recharging terminal i:
• estimating a changing of said reference impedance zii into a modified impedance z′ii,
• updating a voltage of said recharging terminal i, said updating implementing a step for determining a modified inverted loop impedance matrix Zloop_M−1 as a function of a reference inverted loop impedance matrix Zloop_R−1 and at least as a function of an impedance difference between said modified impedance z′ii and said reference impedance zii, delivering a modified voltage U′i for said recharging terminal i, and
• verifying and/or updating a value of power, called available power Pdisp_i, capable of being delivered by said recharging terminal i as a function of said modified voltage U′i, of a maximum power given by said voltage generator and/or of a threshold voltage of said electrical network delivering, in the event of updating, an updated value of available power.
