Utility model content
Problem to be solved in the utility model is that the high pressure connection being directed between current driving force battery can not accurate judgement company
Connect whether abundant, effective present situation, there is provided whether one kind can connect reliable high-tension connector with accurate judgement high-tension connector
Interlock.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows：A kind of high-tension connector it is mutual
Locking device, including control cabinet, control cabinet is interior to include detection module and control cabinet low-voltage interface, the model of detection module
MC9S12XEP100AL, control cabinet low-voltage interface are in series with some battery cases.
Further improvement as above-mentioned technical proposal：
The PAD11/AN11 terminating resistors R2 of detection module one end, resistance R2 other end difference connecting resistance R1's
HVIL1 ends in one end and control cabinet low-voltage interface, resistance R1 another termination voltage 12V, the PAD11/AN11 of detection module
End is grounded through resistance R3, and the PAD11/AN11 ends of detection module connect the HVIL2 ends in control cabinet low-voltage interface through resistance R3, is detected
The PAD11/AN11 ends of module are grounded through electric capacity C1.
The battery case includes low voltage communication connector e, after the low voltage communication connector e series connection in some battery cases with control
Case low-voltage interface connection processed.
The battery case has high-tension connector positive pole socket a and high-tension connector anode socket c, high-tension connector positive pole
Socket a has two interlocking wire harness, and one is connected with high-tension connector anode socket c, and another connects with low voltage communication connector e
Connect.
The high-tension connector anode socket c has two interlocking wire harness, and one connects with the positive pole socket a of high-tension connector
Connect, another is connected with low voltage communication connector e.
The positive pole socket a of high-tension connector is electrically connected with high-tension connector anode plug b, high-tension connector anode socket
C be electrically connected with high-tension connector cathode plug d, high-tension connector anode plug b and high-tension connector cathode plug d have it is short
Two contacts connect.
The utility model takes above technical scheme, has advantages below：More pacify in terms of the connection of electrokinetic cell high pressure
Entirely, reliably, the caused high-tension connector of the reason for avoiding system vulnerability and artificial aspect installs situation not in place, particularly dynamic
In power battery charge and discharge process, high-tension connector installation is not in place or being got loose in vehicle travel process causes contact not filled
Point, cause contact position temperature anomaly to raise, serious can fire hazard.Pass through the self-monitoring inside battery management system
Control, can effectively ensure battery system it is safe to use.
The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment
Embodiment, as shown in Figure 1, a kind of interlock of high-tension connector, including control cabinet 1, include in control cabinet 1
Detection module 3 and control cabinet low-voltage interface 4, the model MC9S12XEP100AL of detection module 3, the PAD11/ of detection module 3
AN11 terminating resistors R2 one end, the resistance R2 other end are distinguished in connecting resistance R1 one end and control cabinet low-voltage interface 4
HVIL1 ends, resistance R1 another termination voltage 12V, the PAD11/AN11 ends of detection module 3 are grounded through resistance R3, detection module 3
PAD11/AN11 ends HVIL2 ends in control cabinet low-voltage interface 4, the PAD11/AN11 ends warp of detection module 3 are connect through resistance R3
Electric capacity C1 is grounded；
Control cabinet low-voltage interface 4 is in series with some battery cases 2, and battery case 2 includes low voltage communication connector e, if dry cell
It is connected after low voltage communication connector e series connection in case 2 with control cabinet low-voltage interface 4, there is battery case 2 high-tension connector positive pole to insert
Seat a and high-tension connector anode socket c, the positive pole socket a of high-tension connector have two interlocking wire harness, one and high-tension connector
Anode socket c connections, another is connected with low voltage communication connector e, and high-tension connector anode socket c has two mutual locking wires
Beam, one is connected with the positive pole socket a of high-tension connector, and another is connected with low voltage communication connector e, and high-tension connector positive pole is inserted
