Battery device for use in car, has safety units inserted in lithium batteries accordingly on conductive pieces, and deactivating leading function of conductive piece immediately during over current

摘要

The device has lithium batteries (40) with positive and negative poles corresponding in each case to conductive strips (20). Conductive pieces (50) electrically connect the batteries with the strips as an end of the conductive pieces is attached to the lithium batteries, while another end of the conductive pieces is connected with the strips. Safety units (60) are inserted in the batteries accordingly on the conductive pieces, and deactivate leading function of the conductive piece immediately during over current.
