Title:
POWER SYSTEM OF ELECTRIC AUTOMOBILE
Document Type and Number:
Japanese Patent JP3761966
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To downsize a device and also, improve the reliability on a power system at large by lightening the burden of the power source to the electrical load at low voltage in an electric automobile where a battery for high voltage for motive power is mounted.
SOLUTION: This power system is dispersed into a plurality of power groups 10, 20, 30,..., with the high-voltage battery 5 being the power source for motor drive of an electric automobile as a common battery, and each power group 10, 20, 30,... is equipped with DC-DC capacitors 11, 21, and 31,..., and electric double-layer capacitors 12, 22, 32,..., respectively, and each load is supplied with power. Each DC-DC converter 11, 21, 31,... is arranged in the section close to the load, using a general relatively small capacity of converter geared to the kind and size of load 13, 23, 33,... connected to each, and when there is instantaneous power increase by load fluctuation, etc., the power is supplied from the electric double-layer capacitor.
