Description
Technical field
The utility model relates to compact power technical field, refers in particular to a kind of discharge load.
Background technology
Along with the development of compact power, emerging in large numbers a lot is the product of the energy based on lithium battery, as lithium battery groups such as toy car battery, portable power source, ups powers, these electric battery market demands are wider, production quantity is many, and test period is long, and production efficiency runs into bottleneck, adopt this discharge load to enhance productivity, save time.
The utility model discloses one and be applicable to low-voltage
,the discharge load of low current power supply, for testing battery capacity fast.
summary of the invention
the technical solution adopted in the utility model is as follows:
A kind of discharge load, is characterized in that: described discharge load comprises resistance, switch
,lED light emitting diode, DC female seat, fan, shell and pcb board.
Described shell comprises housing and front and rear baffle (as Fig. 4 and Fig. 2).
Described DC female seat is arranged on (as Fig. 1) on the front apron of shell.
Described fan is arranged on (as Fig. 2) on the backboard of shell.
Described resistance and LED LED welding are on pcb board.
As shown in Figure 3, described resistance is 4 cement resistors R2, R3, R4, R5 and 1 chromatic circle resistance R1; 4 cement resistors are discharge resistances, and use to product electric discharge, 1 chromatic circle resistance is current-limiting resistance, restriction LED lamp tube electric current; Formed in parallel with fan and 4 cement resistors after LED and R1 series connection, the upper lead-in wire of parallel circuit is connected to DC female seat positive pole VCC, and the lower lead-in wire of parallel circuit is connected with DC female seat negative pole GND, and fan plays thermolysis.
DC female seat is by pin 1 connecting PCB board positive pole, and DC female seat is by pin 4 connecting valve.
Described pcb board is placed in shell, and the front and rear baffle of shell is screwed on housing.
Principle of work: first use normal capacity C
standardelectric battery connect discharge load discharge off record T discharge time
standard.Battery anode is connected with this discharge load VCC, and battery electrode is connected with this discharge load GND, and electric battery starts electric discharge, and LED light is light yellow always, and when electric discharge completes, LED just extinguishes, record T discharge time
survey.The size C of characterizing battery pool-size is carried out according to the length of discharge time
survey=(C
standard* T
survey)/T
standard.
This discharge load advantage is as follows:
1. can solve battery power discharge problem small-sized in enormous quantities.
2. practical, can change according to different battery power discharge mouths.
3. volume is little, can move according to place difference to discharge load.

Fig. 2 be aluminum hull backboard structural representation, fan 3 is arranged on backboard.
Fig. 3 is the circuit theory diagrams of discharge load.
1, DC female seat; 2. switch; 3, fan; 4, housing; 5, front apron; 6, backboard; 7, LED.
Fig. 4 is the overall appearance figure of discharge load.
Embodiment
Be described the principle of this discharge load and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
First use the electric battery of normal capacity, the capacity C of model FGY-s-0018
standard=5000mAh, is connected to discharge load discharge off record T discharge time
standard=1 hour; Measured electric battery model FGY-p-012, this battery anode is connected with this discharge load VCC, and this battery electrode is connected with this discharge load GND, and this electric battery starts electric discharge, and LED light is light yellow always, and when electric discharge completes, LED just extinguishes, record T discharge time
survey=1.5h, carrys out the size C of characterizing battery pool-size according to the length of discharge time
survey=(C
standard* T
survey)/T
standard=5000mAh * 1.5h/1h=7500 mAh.
