Patent Images
1. A power generation system, comprising:
- (a) a generator;
(b) first and second batteries; and
(c) means for coupling the generator and batteries to a load in a load-follower configuration wherein changes in power requirements of the load are compensated by the batteries, and wherein the first battery is charged by the generator while the second battery is being discharged to the load, and vice versa.

Abstract
Batteries are often used for load-following, particularly in combination with generation sources that cannot respond to fast load changes. Batteries that display “memory” (i.e., their ability to operate correctly over their entire depth of discharge depends on their previous level of charge or discharge) cannot adequately follow loads. This invention allows the use of batteries that display “memory” in load-following applications.

16. A power generation system, comprising:
-
(a) a generator;
(b) first and second batteries each of which exhibits memory;
(c) a first power converter operatively coupled between the generator and a load; and
(d) means for coupling the batteries to the power converter such that changes in power requirements of the load are compensated by the batteries, and such that the first battery is charged by the generator while the second battery is being discharged to the load, and vice versa. - View Dependent Claims (17, 18, 19)
