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.
