The present invention relates to a battery pack system. In the battery pack system including a multi-battery according to the present invention, replacement may be easily performed in a lower unit of the battery pack system, the battery pack system including a multi-battery may include the battery modules having various forms and performances and capable of being arranged so as to increase space efficiency of the battery pack system, the battery pack system including a multi-battery includes the battery modules having various forms and performances, such that an energy density of the battery pack system may be improved, and the battery pack system including a multi-battery may allow battery modules having various performances and outputs to maintain states of charge (SOCs) (%) in a uniform ratio by estimating the SOCs of the respective battery modules and re-scaling the SOCs according to a capacity criterion of a control unit.

Battery pack system including multi-battery

A probe used for a high electric current. The prove comprises an outer pipe having a cylindrical configuration which is opened at upper and lower ends thereof; a plunger installed in an upper part of the outer pipe to be elastically extended out of and retracted into the outer pipe, and brought into contact with a contact terminal of a test object; a contact member installed in a lower part of the outer pipe and electrically connected with a contact terminal of a circuit board; and a plurality of contact wires installed at a region where the plunger and the contact member are engaged with each other, to electrically connect the plunger to the contact member, and each having one end which is bent outward.

The present invention relates to an electrical connecting device, which enables to connect electrically an integrated circuit substrate to a printed circuit board in direct or to test an integrated circuit device in use of a printed circuit board. The present invention includes a housing having a slot and a separating means wherein a board is inserted into the slot and the separating means separates the inserted board, a space part formed at a bottom of the housing, a coupling means coupled with the spacing part of the housing wherein a coupling space part connected to the slot and wherein a plurality of penetrating holes are perforated with even interval in a bottom of the coupling means, an elastic means installed on the coupling means with a pair of rows wherein the elastic means is contracted by an external pressure, and a contacting means of which contacting part is inserted into the penetrating holes to be contacted with the elastic means tightly and of which other contacting part is built in the coupling space part to protrude out to be inserted into the slot wherein the contacting means is contacted with a conductive substance of the board. Accordingly, the present invention enables to provide an excellent contact, prevent malfunction generated from connecting the contacting points due to the complicated structure, and prevent the damage on the conductive contacting region of the PCB and the like due to the fluctuation of a contacting point from right to left, and vice versa.
