Abstract
Abstract A charging system for a stand-by power supply comprising a battery having plurality of series-connected cells and a switching means for periodically and sequentially charging sections of the battery, thereby to minimize voltage variation between the normal DC power source voltage and the stand-by power supply discharge voltage applied to a load during the nonfunctioning of the DC power source.

Claim 12
Independent Claim
155 words
A method for charging a stand-by power system designed to supply electrical power to a load during the non-functioning of the normal power source for said load, said system comprising a plurality of rechargeable cells connected in circuit, said cells being divisible, for charging, into a plurality of sections of at least one cell each and a supplemental section of at least one cell, said method comprising the steps, in sequence, of: a. connecting said supplemental section in parallel with one of said plurality of sections; b. disconnecting said one section from the remaining sections, thereby to leave said supplemental section in series with said Remaining sections; c. connecting said one section to a source of charging current; d. disconnecting said one section from said charger after charging; e. reconnecting said one section in parallel with said supplemental section; and f. repeating steps (a) through (e) for a second one of said plurality of sections.
Claim 13
Independent Claim
155 words
A method for charging a stand-by power system designed to supply electrical power to a load during the non-functioning of the normal power source for said load, said system comprising a plurality of rechargeable cells connected in circuit, said cells being divisible, for charging, into a plurality of sections of at least one cell each and a supplemental section of at least one cell, said method comprising the steps, in sequence, of: a. connecting said supplemental section in parallel with one of said plurality of sections; b. disconnecting said one section from the remaining sections, thereby to leave said supplemental section in series with said Remaining sections; c. connecting said one section to a source of charging current; d. disconnecting said one section from said charger after charging; e. reconnecting said one section in parallel with said supplemental section; and f. repeating steps (a) through (e) for a second one of said plurality of sections.
