Abstract

Apparatus and methods are provided for charging rechargeable batteries using amplitude and frequency modulated current.

Claims

1. A method of charging a rechargeable battery, the method comprising:

applying amplitude and frequency “

SuperWaves”

modulated electrical power to the battery;

monitoring at least a first characteristic parameter of the charging process during the charging;

comparing at least the first characteristic parameter with corresponding stored sets of reference parameters representing fully charged battery conditions;

selecting, based on the comparison, one of the stored sets of reference parameters; and

terminating the charging process when at least the first characteristic parameter has reached the one of the stored sets of reference parameters.

2. The method of claim 1, wherein at least the first characteristic parameter is the battery temperature and a second characteristic is the average voltage derivative.

3. The method of claim 1, wherein the charging process is terminated if the measured value of at least the first characteristic parameter exceeds a predetermined value for the respective parameter.

4. The method of claim 1, wherein the charge state of the battery is maintained after termination of the charging process by feeding a trickle “

SuperWaves”

modulated current to the battery to maintain the battery charge.

5. An apparatus for charging a rechargeable battery, the apparatus comprising:

a programmable or pre-programmable power supply able to generate an amplitude and frequency “

SuperWaves”

modulated current;

means for monitoring at least one characteristic parameter of a charging process during the charging;

means for terminating the charging on exceeding a predetermined parameter indicative of the battery approaching its full charge; and

means for providing a trickle “

SuperWaves”

charging after the battery is fully charged.
