PURPOSE:To effectively prevent generation of G pulses in an alternator by piling dielectric films and filmy electrodes alternately on the periphery of a housing in a car battery and winding them so that capacitors connected with the battery are formed to decrease resistance on their connection parts. CONSTITUTION:Filmy electrodes 2 and 3 with dielectric films 1 interposed between them are laminated alternately on the periphery of a battery housing 61 in a car battery 6. This electrode 2 is connected with a positive electrode 4 of the battery 6, and the electrode 3 is connected with a negative electrode 5 of the battery 6. This dielectric film 1 is made of electrolytic paper, and the electrodes 2 and 3 are made of aluminium foils. Thus, a capacitor of large capacity of several farads is formed between the electrodes 2 and 3, and so a voltage drop due to short-time large current at the time of a starting operation can be prevented simply and effectively in a small space without a necessity of installing a large capacitor individually. |
