Abstract
A battery voltage regulation circuit is provided for regulation the charging voltage of a battery. The system of the present invention includes a battery charger and a plurality of series connected batteries. Each of the plurality of series connected batteries are connected in parallel with a battery voltage regulator circuit. Each battery voltage regulator identifies excess battery current by using a voltage temperature compensation factor to compare the voltage of a battery to a reference voltage. A battery bypass circuit is used to remove excess battery current from a battery bath. In addition to being used in conjunction with a plurality of series connected batteries, the present invention may be used with a single charging battery to achieve the same results.
