Abstract: A method and apparatus (FIG. 1) for optimizing recharging of batteries (20) in an electric or hybrid vehicle that uses an electric motor (35) powered by the batteries (20) and having a regenerative system (10) that uses mechanical forces of the vehicle to generate current to recharge the batteries. The output of the regenerative system is controlled (15 and 35) to supply a maximum amount of current to recharge the batteries immediately after termination of a pulse or continuous discharge thereby to recapture a larger portion of the discharge current (FIG. 3) and the battery voltage is monitored (35) during recharge and the voltage is controlled (15) during charge so that it does not exceed a predetermined value at which battery gas evolution takes place (FIG. 2), thereby permitting the battery to be charged to a relatively high state of charge.

Abstract: In accordance with the invention, there is a battery defect detection method comprising applying a current ramp to a battery; determining a first time (t 1 ) when a current of the battery reaches a maximum current (I peak ), and determining a second time (t 2 ) when a terminal voltage of the battery reaches a maximum voltage (V peak ). The method also includes determining a differential (d), wherein (d)=/(t 1 )-(t 2 )/, and wherein (d) corresponds to a magnitude of defects in the battery.

Abstract: A method of predicting by non-invasive testing the available energy of a battery at any state of charge by acquiring data of the parameters of internal resistance (IR), open circuit voltage (OCV) and temperature (T), the points of voltage and current of the slope on a positive current ramp of Vup and Iup at the transition from charge to overcharge and on a negative current ramp of Vdn and Idn at the transition from overcharge to charge for a plurality of batteries. Next an algorithm in the form of a linear equation is developed using this data. The available energy of a battery under test is predicted by acquiring from it the numerical data values of these parameters and applying them to the algorithm.
