For measuring and the connecting terminal of afterflow.
Background technique
Battery group is widely used in DC back-up power supply.In recent years, the on-line monitoring for battery group and guarantor
The product and equipment of shield are also more and more, all these products and equipment, without exception, the anode and cathode of battery are needed to connect
Enter to acquire equipment.
The conventional mode of connection used between acquisition equipment and the anode and cathode of battery has following several: 1) using gold
Belong to clip, the end of metal holder is welded or crimped with the conducting wire of acquisition equipment, and the clip portion of metal holder clamps battery
Screw on the pole of positive or negative pole；2) use metal holder, the conducting wire welding of the end of metal holder and acquisition equipment or
It crimps, copper bar is connected on the pole of the positive or negative pole of battery and passes through screw tightening, the clip portion of metal holder is clamped
Copper bar；3) OT cold end terminal or UT cold end terminal, the end tail of cold end terminal and the conductor compression jointing for acquiring equipment, cold end terminal are used
End pass through the positive or negative pole of battery pole on screw tightening；4) copper bar, one end of copper bar and acquisition equipment are used
Conducting wire welding, the screw tightening on pole that the other end of copper bar passes through the positive or negative pole of battery.
These above-mentioned modes of connection have respective advantage and disadvantage:
Metal holder is used, although easy-to-connect, the positive or negative pole of the clip portion and battery of metal holder
The contact of screw or copper bar on pole is unreliable, and the position pressed from both sides every time can not be identical, leads to voltage, electric current etc.
Parameter measurement inaccuracy, is only applicable to the equipment not high to parameter request, such as discharger.
Using OT cold end terminal or UT cold end terminal, when connection, needs to disconnect battery group, the end of cold end terminal and electricity
Screw contact on the pole of the positive or negative pole in pond is reliable, and measurement point immobilizes after screw tightening, voltage, electric current etc.
Parameter measurement is more accurate, but cannot carry high current for a long time, is suitable for and for a long time connection higher to parameter request and transports
The equipment that row infrequently exits, such as on-line monitoring equipment；And shown needing four lines using cold end terminal according to experiment
In the equipment for making measurement, respectively need to stack two cold end terminals on the anode of battery and the pole of cathode, but two cold pressing ends
Still there is measurement point difference and lead to small data difference in sub- mounted on top, needs are accurately calculated after tightening screw
It is for equipment or not ideal enough, and while tightening screw, there are problems that being inconvenient to install, and the end of cold end terminal can also go out
Existing deformation problems cause to twist not tight screw.
Using copper bar, copper bar contacts reliably with the screw on the pole of the positive or negative pole of battery, can carry for a long time big
Electric current, but generally copper bar is required to have larger size, it also needs to weld in the conducting wire of the acquisition equipment with small size, installation is not square
Just.
Currently, for battery group on-line monitoring with protection product and equipment, it usually needs measure battery voltage,
The parameters such as temperature, internal resistance, and internal resistance needs are calculated by discharging in short-term, must thus acquire electricity when electric discharge in short-term simultaneously
Pressure and discharge current generally use four-wire system (positive two lines and cathode two since discharge current is bigger (50A or more)
Line, a line survey voltage, and another line is for discharging to calculate discharge current).Internal resistance calculating is that very precise measurement is needed to put in short-term
Voltage and discharge current when electric, it is very big that several millivolts of difference just can lead to internal resistance calculated result difference, it is therefore desirable to precise measurement,
And by voltage when discharging in short-term of these above-mentioned modes of connection acquisition with discharge current because there are measurement point differences to lead to essence
Exactness is not ideal.
