Method for Managing a Bank of Rechargeable Batteries Using the Coup De Fouet Effect on Charging
First Claim
1. A method for managing a bank of rechargeable batteries comprising a sequential charging of the batteries of the bank according to an order of priority and analysis of the state of charge of the batteries, the method comprising partial charging of at least one batter subset, measurement during said partial charging of electrical parameters representative of a coup de fouet effect on charging, comparison of the amplitudes of the coup de fouet effects on charging associated with the different batteries of the subset, the batteries of the bank being charged during a subsequent sequential charging cycle of the batteries of the bank according to an order of priority modified according to said comparison.

Abstract
The batteries of at least one battery subset are partially and preferably simultaneously charged; during this partial charging, electrical parameters representative of a coup de fouet effect on charging are measured to enable the extent of discharge of each of the batteries of the subset to be analyzed; the batteries are then charged sequentially with an order of priority that depends on the extent of discharge of the different batteries; priority is preferably given to charging the most extensively discharged batteries.
