Title:
APPARATUS AND METHOD FOR IDENTIFYING AND CHARGING BATTERIES OF DIFFERENT TYPES
Document Type and Number:
WIPO Patent Application WO1997048162
Kind Code:
A3
Abstract:
An apparatus for charging batteries of different types is disclosed as including support means for receiving a battery having a positive terminal and a negative terminal, a battery interface for electrically coupling the battery charging apparatus to the received battery, and a circuit for identifying the particular type of the received battery and supplying a charging current to the received battery in accordance with a specified charging algorithm applicable to the particular battery type. The battery interface includes a positive contact positioned within the support means so as to engage the positive terminal of the received battery, a negative contact positioned within the support means so as to engage the negative terminal of the received battery, and at least one sensing contact positioned within the support means which senses a voltage from the received battery indicative of a particular battery type. The circuit identifies the particular battery type by whether or not the sensing contact is engaged by one of the battery terminals, by whether the voltage sensed by the sensing contact is substantially equivalent or not to a voltage received by one of the battery terminals, by whether the voltage sensed by the sensing contact creates a high or low logic level in the circuit, or by which combination of logic pins is engaged by the battery terminals.
