  • Patent number: 5973479
    Abstract: A device (10) and method for charging rechargeable type batteries (11) in which the charging current (Ib) supplied the batteries is measured and the temperature variation (.DELTA.Teff) of the batteries is determined over an established interval of time. Furthermore, this variation is compared with a reference value (.DELTA.Tref) so that battery charging can be interrupted when the variation equals or exceeds the reference value (.DELTA.Tref). The reference value (.DELTA.Tref) is defined in relation to the current (Ib) charging the batteries (11) so as to take into account all the possible current values with which the batteries are charged. To advantage, battery charging is interrupted and battery overloading avoided when the charging of the batteries (11) is terminated by a very low charging current. The device (10) and method are particularly suitable for charging the batteries of electronic equipment, such as a personal computer or similar.
