Document Type and Number:
WIPO Patent Application WO/2020/171423
Kind Code:
A1
Abstract:
An apparatus for recovering electricity remaining in a waste battery of an electric car according to an embodiment of the present invention comprises: an inverting unit electrically connected to a waste battery so as to convert direct-current electricity in the waste battery into alternating-current electricity with a first voltage; multiple load distribution units which can be electrically connected to the inverting unit and to which the output of the inverting unit is distributed; a main transformer which changes the output voltage of load distribution units operated among the multiple load distribution units to a second voltage higher than the first voltage; and a controller which controls the number of load distribution units operated among the multiple load distribution units according to the amount of electricity remaining in the waste battery.
