RECHARGEABLE BATTERY ASSEMBLY AND POWER SYSTEM USING SAME
First Claim
1. A method for charging a plurality of rechargeable battery assemblies electrically connected in series with a battery charger, each battery assembly comprising a rechargeable battery having a positive terminal and a negative terminal, and means for self-discharging the rechargeable battery electrically connected in parallel with the battery terminals, said method comprisingcontinually determining a voltage across the positive and negative terminals of each battery, thenif the voltage is ≧
- a preset value, self-discharge the battery until the voltage is equal to the preset voltage, thenfurther self-discharge the battery for a period of time (t), wherein time (t) provides a discharge of the battery charge corresponding to a preset percentage of the battery'"'"'s charge capacity.
