  • METHOD OF PRODUCING AN ELECTRIC BATTERY
    Publication number: 20150204948
    Abstract: The invention relates to a method of producing a battery (14), in which method multiple cells (c1-c12) are arranged in receiving locations, taking account of the respective internal resistances of the cells and the suitability of each individual location to dissipate heat. For example, the most resistive cells can be assigned the locations best suited to dissipating heat. In this way, the invention can be used to produce a battery in which the temperature rise is reduced, such that battery life is improved.

  • Method for managing charging of a rechargeable battery
    Patent number: 8093866
    Abstract: The management method comprises a charging phase and may comprise an optional prior phase of estimating the state of charge of the battery. Comparison of the absolute value of the slope of the voltage at the battery terminals with a full-charge threshold at the end of each period, when a pulsed current is applied, is used as end-of-charging criterion in the charging phase and/or as full-charge criterion in the phase of estimating the state of charge. The charging phase by pulsed current is interrupted when the slope reaches the full-charge threshold. This same comparison constitutes the criterion for estimating the necessity for going to a charging step after the prior phase of estimating the state of charge of the battery.

  • Method for managing charging of a rechargeable battery
    Publication number: 20100060240
    Abstract: The management method comprises a charging phase (F2, F3) and may comprise an optional prior phase (F1) of estimating the state of charge of the battery. Comparison of the absolute value of the slope (P) of the voltage at the battery terminals with a full-charge threshold at the end of each period, when a pulsed current is applied, is used as end-of-charging criterion in the charging phase and/or as full-charge criterion in the phase of estimating the state of charge. The charging phase by pulsed current (F3) is interrupted when the slope (P) reaches the full-charge threshold. This same comparison constitutes the criterion for estimating the necessity for going to a charging step (F2, F3) after the prior phase (F1) of estimating the state of charge of the battery.
