Description
Technical field
This utility model relates to the connector in electrokinetic cell system, particularly relates to a kind of electrokinetic cell system high-voltage connector for judging connection reliability。
Background technology
Society now, increase along with industrial development and social need, the problem such as environmental pollution, energy shortage becomes increasingly conspicuous, and lithium ion battery is due to its green non-pollution, the feature such as voltage is high, capacity is big, volume is little, light weight, operating temperature range width, cycle performance are superior, it is widely used in every field, especially electric vehicle and energy storage。
In order to ensure the safety of battery, for the temperature of the voltage of each cell, battery module and high pressure connection etc., the operating current of battery system and insulating properties, it is required for being carried out monitor in real time by battery management system。Simultaneously because car load is all big current work, any loose contact all can cause high temperature to occur, so needing the reliability monitor in real time that high pressure is connected, it is to avoid owing to connectivity problem causes the generation of fire。
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electrokinetic cell system high-voltage connector for judging connection reliability, it is possible to increase the connection reliability of high-voltage connector。
This utility model solves its technical problem and be the technical scheme is that a kind of electrokinetic cell system high-voltage connector for judging connection reliability of offer, including multiple high-voltage interlocking loops, one end is an opening two holding wires in described high-voltage interlocking loop, the other end is a short-circuit line, and the position of described two holding wires is mutually corresponding with the position of described short-circuit line；The holding wire in all high-voltage interlocking loops is sequentially connected in series；Described short-circuit line is equipped with Thermal Cutoffs。
Wherein, the holding wire one end in the high-voltage interlocking loop being sequentially connected in series is connected with high/low level, and the other end connects the input of micro control unit。
The fusing-off temperature of described Thermal Cutoffs is 100 DEG C～120 DEG C。
Described Thermal Cutoffs adopts the mode directly contacted with connector metal to install。
Described high-voltage interlocking loop is integrated in inside high-voltage connector。
Beneficial effect
Owing to have employed above-mentioned technical scheme, this utility model is compared with prior art, have the following advantages that and good effect: all holding wires are attached by this utility model in series, and judge whether all of high-voltage connector is installed by micro control unit and put in place, thus control the power output of car load。Meanwhile, the short-circuit line of the one end in high-voltage interlocking loop adds Thermal Cutoffs, when occurring connector wear and tear for a long time or process the bad high temperature fault caused, it is possible to disconnect high-voltage interlocking loop in time, it is to avoid the fire condition that temperature control causes occurs。
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model。
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further。Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model。In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally。
Embodiment of the present utility model relates to a kind of electrokinetic cell system high-voltage connector for judging connection reliability, as shown in Figure 1, including multiple high-voltage interlocking loops 1, one end is an opening two holding wires 2 in described high-voltage interlocking loop 1, the other end is a short-circuit line 3, and the position of described two holding wires 2 is mutually corresponding with the position of described short-circuit line 3；The holding wire 2 in all high-voltage interlocking loops 1 is sequentially connected in series；Described short-circuit line 3 is equipped with Thermal Cutoffs 4。Wherein, holding wire 2 one end in the high-voltage interlocking loop 1 being sequentially connected in series is connected with high/low level, the other end connects the input of micro control unit, so can judge whether that all of high-voltage connector is all installed by micro control unit and put in place, thus controlling the power output of car load。
It is seen that, short-circuit line in high-voltage interlocking loop adds Thermal Cutoffs, Thermal Cutoffs is running into high temperature (as more than 100 DEG C) just disconnection, so that multiple high-voltage interlocking loops of series connection disconnect, by micro control unit, (this micro control unit can be the micro control unit of battery management system, can also be the micro control unit of entire car controller) judge to obtain fault message, thus taking appropriate measures further。
In electrokinetic cell system, especially passenger car, major part high-voltage interlocking loop is integrated in inside high-voltage connector, including total just, total negative output, charge high voltage interface, maintenance switch, the high-voltage connector etc. that case is connected with case。The one end in high-voltage interlocking loop is two holding wires of an opening, and the other end is a short-circuit line, and after connector is inserted into the end, two holding wires are connected by short switch。All of holding wire is connected in series to, termination high level or a low level, the input port of another termination micro control unit, judges that determining whether all high-voltage connectors are installed puts in place by micro control unit。Wherein, the short-circuit line in high-voltage interlocking loop adds Thermal Cutoffs, weares and teares for a long time if there is connector or process the bad high temperature fault caused, it is possible to disconnect high-voltage interlocking loop in time, it is to avoid the fire condition that temperature control causes occurs。This Thermal Cutoffs can set as requested, just disconnects as set 100 DEG C～120 DEG C。This Thermal Cutoffs takes the mode directly contacted with connector metal to install, such that it is able to rapidly variations in temperature is reacted。
As can be seen here, all holding wires are attached by this utility model in series, and judge whether all of high-voltage connector is installed by micro control unit and put in place, thus controlling the power output of car load。Meanwhile, the short-circuit line of the one end in high-voltage interlocking loop adds Thermal Cutoffs, when occurring connector wear and tear for a long time or process the bad high temperature fault caused, it is possible to disconnect high-voltage interlocking loop in time, it is to avoid the fire condition that temperature control causes occurs。
