This application claims preferential on January 7th, 2013 South Korea patent application submitted the 10-2013-0001558th
The content of power, this application file is fully incorporated the present invention by reference.
Technical field
The present invention relates to the sensing component for secondary battery module and has the secondary battery module of the sensing component.
Background technique
Secondary cell is obtained as the battery that can be charged and discharged repeatedly by the electrochemical reaction of internal active material
Obtain energy.The performance of such secondary cell by such as charging method, degree of discharge, keeping and use when temperature environment or
The influence of load level, charge and discharge number etc..
Nearest secondary cell is exploited to lithium ion battery, lithium polymer battery with high-energy density and lightweight
Or the fields such as fuel cell, and it is variously employed to industry use, automobile, carries use or mobile power supply in terms of purposes
Device.
Meanwhile the various circuits for protecting and controlling being installed in such secondary cell, on plain battery, and two
Primary cell be modular be suitable for by external system to be used, thus obtained in the form of secondary battery module using.
The circuit is applied not only to the charge and discharge of control secondary battery module, and in secondary battery module overcharge or mistake
For cutting off circuit when electric discharge, to extend the service life of secondary battery module, and then explosion or the danger of fire are prevented.In addition,
Monitoring system is used, recently with residual discharge amount or the temperature etc. for informing the secondary battery module in use in real time.
The monitoring system includes sensing component, lasting detection constitute the battery unit of secondary battery module voltage or
Temperature etc., to be informed to outside.
The sensing component has the sensing PCB being electrically connected with the battery pole ear (cell tab) of each battery unit, passes through
The connector being mounted on the sensing PCB informs temperature or the voltage etc. of battery unit to outside.
Meanwhile in existing sensing component, in order to which the sensing PCB for being equipped with connector is electrically connected, need to
The leg (leg) of battery pole ear electrical connection is welded, and correspondingly its assemblability is bad and is particularly unfavorable for safeguarding and repair
It is multiple.
As known fact, sensing component is by being fixed on the substrate holder of secondary battery module and being fixed on the substrate branch
The sensing PCB (its various parts and circuit that are formed with voltage and temperature for detecting battery unit) on frame top is constituted, will
It is very inconvenient that the connection leg for being fixed on substrate holder is attached with the circuit for being installed on sensing PCB.That is, due to
The leg and sensing PCB are fixed as one by welding manner, the assembling and separation phase for the sensing PCB of substrate holder
Answer ground complicated.
The reference view for the problem of Figure 10 and Figure 11 is for illustrating the existing sensing component.
Referring to figure it is found that having multiple legs 65 on the both sides of substrate holder 69.The leg 65 is in substrate holder
Insert injection moulding (insert injection) forms in 69, and the one end of horizontal extension is connect with battery pole ear, the other end
65a projects upwards to be combined with sensing PCB 63.
It is such as connected as described above in addition, being formed on sensing PCB 63 in conjunction with the top of the substrate holder 69
The various parts and circuit of device 67 etc., and there is through-hole 63a in both sides.The through-hole 63a is configured so that fixed screw
63b is passed downwardly through in conjunction with internal thread hole 69a.
Meanwhile multiple combined hole 63c are formed in the marginal portion of the sensing PCB 63.The combined hole 63c be
By sense PCB 63 be placed on substrate holder 69 when make the other end 65a of the leg 65 upwardly through access.It is described
The other end 65a is with the state by combined hole 63c come the part of the circuit connection with sensing PCB 63.
As described above, the connection for the sensing PCB 63 of substrate holder 69 is extremely difficult in existing sensing component
, this is because needing that the connection of the other end 65a and sensing PCB circuit of the leg 65 on sensing 63 top PCB will be projected to
It is welded one by one in portion.Moreover, in order to which the welding process will be using flowing welding and reflux technique, thus not only operation is very
Inconvenience also needs masterful technique.
Further, since disconnections or the other reasons such as circuit pattern, component or fuse of sensing PCB 63, sense PCB
In idle situation, the reparation of sensing component 61 is in fact impossible, needs integrally to replace the module including battery unit.
If the malfunction of the sensing PCB occurs, needs to sense PCB 63 anyway and separated from substrate holder 69
And new sensing PCB is replaced, however as described above, is completely fixed with sensing PCB by welding in the leg of substrate holder
In the case of, it is difficult to be easy and neatly separates sensing PCB from substrate holder.Correspondingly, poor operability.
