A kind of battery management system module of electric automobile is used standard cable
Technical field
The utility model relates to cable, and the battery management system module that particularly relates to a kind of electric automobile is used standard cable.
Background technology
Traditional electric automobile uses a large amount of secondary cells that comprises lithium battery as power source; Yet; Lithium battery must with battery management system (Battery Management System; Initialism is BMS) Combination application is in electric automobile, if lithium battery does not have the protection of battery management system, easyly overcharges, crosses and catastrophe failure such as put, overheated; After very fast the inefficacy scrap; Therefore, all dispose a plurality of battery pack (Battery Pack) on the practical electric automobile, so-called battery pack is meant that at least two monomers electricity cores (Cell) series connection that voltage capacity can't be met consumers' demand or parallel connection combination add the battery pack of the voltage capacity of can meeting consumers' demand that outer casing forms.According to the electric automobile vehicle type structure, each battery pack is installed in the diverse location of electric automobile, generally needs many stube cables; Because the battery pack installation site is inequality; Adopt controller local area network's (Controller Area Network, initialism are CAN) bus communication cable, the 24V/12V service cable of differential signal transmission in each battery pack between the BMS module, and the length of the signal cable used of non-battery pack has nothing in common with each other; Belong to non-standard component; And vehicle more modification number all need again design, mostly nonstandard cable is manual processing, manufacturer is difficult to large batch of use machine and makes cable; Greatly waste of manpower and material resources, and prolong the delivery time.
Summary of the invention
The utility model technical problem to be solved is the defective that remedies above-mentioned prior art, provides a kind of battery management system of electric automobile to use standard cable.
The technical problem of the utility model solves through following technical scheme.
The battery management system module of the electric automobile of the utility model is used standard cable; Comprise cable and joint; Said cable is made up of three T font adapter leads with upper end by the yi word pattern straight-through cable that has two terminations more than with more than one; The termination of T font adapter lead vertical section is connected to the battery cell management system module; Two terminations join with a termination of the yi word pattern straight-through cable of the right and left setting respectively about its horizontal segment, and said yi word pattern straight-through cable is the cable of three kinds of specification length.
Said T font adapter lead is made up of a T type threeway node, three stube cables and three terminations, and three openings of threeway node join with three terminations respectively through three stube cables.
Two above yi word pattern straight-through cables have been connected in series between two T font adapter leads.
Said T font adapter lead is made up of with upper end an above T type threeway node, three above stube cables and three; All be connected with a stube cable between each T type threeway node horizontal segment; Each T type threeway node vertical section opening joins through a stube cable and a termination, and the T type threeway node horizontal segment opening of T font adapter lead both sides outermost joins through the termination of two stube cables and its horizontal segment the right and left respectively.
Two above yi word pattern straight-through cables have been connected in series between two T font adapter leads.
The yi word pattern straight-through cable of said three kinds of specification length is respectively 1 meter, 2 meters and 3 meters long cables.
The termination of yi word pattern straight-through cable is the mutual termination of accepting that engages of matching with the termination of T font adapter lead horizontal segment, constitutes detachably to be fixedly connected.
It is said that to accept detachable fixed connection the in termination be that the multi-pin connector socket that assembly engages connects.
Said multi-pin connector socket is the water proof type plugs and sockets.
Said water proof type plugs and sockets is the waterproof Aviation Connector.
The utility model is owing to adopt the yi word pattern straight-through cable of gauge length and the combination of T font adapter lead to use; To detachably be fixedly connected and multicore water proof type plugs and sockets that assembly engages is applied to being connected of yi word pattern straight-through cable and T font adapter lead in addition; Thereby make anyway the battery management system module on the electric automobile is provided with; Can both adopt standardized cable to connect together; Method of attachment is easy, not only saves time but also laborsaving, but also can avoid the waste of cable.

Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further explain.
Like Fig. 1,2, shown in 3; The battery management system module of the electric automobile of the utility model is used standard cable; Comprise cable and joint; Said cable and joint are to manufacture standard component by factory according to the standard-run quantity of setting; Battery management system module 6 distributing positions according to the different electric electrical automobile make up use again, and this standard cable is used for adopting between the battery pack battery management system module 6 of electric automobile the CAN of controller local area network bus communication cable, the 24V/12V service cable of differential signal transmission, and the telecommunication cable used of non-battery pack.
This standard cable is made up of three T font adapter leads 2 with upper end 3 by the yi word pattern straight-through cable 1 that has two terminations 3 more than with more than one; 2 fens vertical sections of said T font adapter lead and horizontal segment; Each vertical section is to link to each other with horizontal segment through a T type threeway node 4; End end at each vertical section is provided with termination 3; The termination 3 and the battery cell management system module 6 of vertical section join; Two end ends are two terminations 3 about T font adapter lead 2 horizontal segments, and these two terminations 3 join with a termination 3 of the yi word pattern straight-through cable 1 that is arranged on T font adapter lead 2 the right and lefts respectively, and the standard component that said yi word pattern straight-through cable 1 is three kinds of specification length is respectively the cable of 1 meter, 2 meters and 3 meters length.
