NONAQUEOUS ELECTROLYTE, NONAQUEOUS SECONDARY BATTERY, CELL PACK, AND HYBRID SYSTEM
FIG4 is a schematic explanatory diagram illustrating a hybrid power system according to a forty fifth embodiment
An example of a specific configuration of the forty fifth embodiment will now be described. FIG4 is a schematic explanatory diagram illustrating a hybrid power system according to the present invention. Here, the reference numeral 1 refers to a "non-aqueous secondary battery (LIB)", the reference numeral 2 refers to a voltage monitoring circuit (BMS), the reference numeral 4a refers to a "capacitor (secondary battery other than the LIB)", and the reference numeral 5 refers to a small-sized hybrid power system. This small-sized hybrid power system 5 can be repeatedly charged and discharged. Specifically, as illustrated in FIG4, this small-sized hybrid power system 5 includes non-aqueous secondary batteries (LIB) 1 in which four cells are connected in series, and a voltage monitoring circuit (BMS) 2 that individually monitors terminal voltages of each of the plurality of non-aqueous secondary batteries. In addition, a capacitor 4a (as a secondary battery other than the LIB) is connected in parallel to the LIB 1. The capacitor preferably includes an electric double layer capacitor, a lithium ion capacitor, or the like.
