Description of the Related Art As prior art, a plurality of storage capacitors, such as a plurality of electric double layer capacitors, connected in series along a main electric line, and switching regulators connected in parallel to each of these storage capacitors, A sub-circuit which connects each output terminal of the switching regulator to the main circuit (the current flowing through the sub-circuit is set to be at most about 10% of the current flowing through the main circuit) and a storage capacitor Are monitored, and the higher the inter-terminal voltage being monitored, the greater the conduction time ratio,
2. Description of the Related Art A power storage device including a monitoring / control circuit for controlling a switching operation of a switching regulator connected in parallel with each other is known (Japanese Patent Application Laid-Open No. H10-52042).
A battery pack in which a plurality of lithium-ion batteries are connected in series, wherein the high-frequency internal impedance is lower than that of the lithium-ion batteries, a large-capacity capacitor (for example, an organic semiconductor solid electrolytic capacitor or the like), or more than the lithium-ion battery voltage There is also known a power storage device including a lithium ion battery pack connected in parallel with a lithium ion battery in order to obtain a high voltage and a high capacity with an assembled battery (for example, a nickel cadmium battery) having a voltage of (2). −4537

といった問題点があった。However, in the above-mentioned prior art, in Japanese Patent Laid-Open No. Hei 10-52042, each switching regulator can be constituted by an inexpensive element having a low rated value by a sub-circuit configuration. However, since the voltage between the terminals of each capacitor is monitored individually, the system becomes very complicated. Further, if the monitoring / control system malfunctions, a certain capacitor becomes high in voltage, causing a problem that the capacitor explodes. Also, Japanese Patent Application Laid-Open No. 9-45
In No. 375, the apparent high-frequency internal impedance of the lithium-ion battery pack is lowered from its configuration,
Although it is possible to suppress the heat generation of the battery, there is a problem that since a plurality of lithium ion batteries are connected in series, the high-frequency internal impedance rises by that amount and it is difficult to perform a rapid discharge.
