Technical field
The present invention relates to a kind of detecting instrument, particularly a kind of battery capacity detector for quick measurement battery capacity
And battery capacity check method.
Background technology
At present, in order to prevent operator on duty's maloperation in transformer station, the electricity coding for operating on lock, switch, grounding switch
Lock and mechanical lock are all equipped with Intelligent key.Intelligent key is the main unlocking tool of anti-misoperation monitoring system, and it is by communication
Operation order or operational order that Receiving Host is assigned, it is dynamic that operating procedure or operational order according to operator perform unblock to equipment
Make, instruct correct operation equipment, prevent maloperation.In order to ensure the smooth of operation, the computer key of transformer station is typically located throughout the year
It is in charged state therefore very big to the lithium battery infringement of computer key.So lithium battery has been not up to service life capacity just
, often there is the situation of interrupt operation because computer key does not have an electricity in wretched insufficiency, and it is long to cause to stop electric power feeding time, influence power supply
The reliable power supply of user.In order to avoid this problem occurs, big multi-Substation every year all can be to the battery of all of computer key
All change one time.However, because the situation of each transformer station is different, the operation of a part of transformer station is not a lot, computer
The battery of key also can be what is be continuing with, but cannot judge the quality of battery, in order to ensure operation, or will all more
Change, consume excessive.And influence of the excessive old and useless battery to environment is very serious.
The content of the invention
In view of the above mentioned problem that prior art is present, it is an object of the invention to provide a kind of battery capacity detector, should
Battery capacity detector can be quickly to lithium battery capacity detect, judge whether to need to carry out charging operations to battery.
To achieve these goals, a kind of battery capacity detector that the present invention is provided, including：
For the external power supply powered；
The dynamic detection loop accessed for mesuring battary and measured to its voltage rate of descent；
Loop is indicated, voltage rate of descent and the preset value for the dynamic detection loop to be determined are compared to judge
Mesuring battary capacity, as described voltage rate of descent be more than preset value, judge that mesuring battary capacity is low, otherwise then judge mesuring battary
Capacity is normal.
Preferably, also including a timing circuit, it is arranged in parallel with the dynamic detection loop.
Preferably, the instruction loop is included for indicating respectively the discharge condition of mesuring battary, under-voltage condition or just
The indicator lamp of normal state.
Preferably, the indicator lamp is light emitting diode.
Present invention also offers a kind of battery capacity check method, the method includes：
Step 1, measures the voltage rate of descent of mesuring battary；
Step 2, the voltage rate of descent is compared with preset value, and voltage rate of descent is more than preset value as described, sentences
Disconnected mesuring battary capacity is low, otherwise then judges that mesuring battary capacity is normal.
The battery capacity detector provided by the present invention, can be carried out soon to the battery module of the equipment using lithium battery
The electric quantity test of speed.For example, the lithium battery to computer key in transformer station is detected, by off-capacity and serious deterioration
Battery changed in time, it is ensured that battery replacement cost is considerably reduced while stable power-supplying.
Brief description of the drawings
Fig. 1 is the theory diagram of apparatus for testing electric capacit in batter of the invention.
Fig. 2 is the circuit diagram of apparatus for testing electric capacit in batter of the invention.
Specific embodiment
Technical scheme is further described in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of battery capacity detector that the present invention is provided, including：
For the external power supply 1 powered, 220V civil powers can be generally directly accessed here, but in actual use,
The power supply will be converted into 15v to carry out coherent detection work by transformer；Accessed for mesuring battary and its voltage rate of descent is entered
The dynamic detection loop 2 of row measurement；In the middle of measure loop, mesuring battary is discharged, and detection circuit can dynamically obtain du/
The numerical value of dt, the i.e. numerical value of voltage rate of descent.This numerical value can be presented as the difference of the slope of discharge curve in a coordinate system；This
Invention further by indicating loop 3, voltage rate of descent that the dynamic detection loop 2 is determined and preset value be compared with
Judge battery capacity, voltage rate of descent is more than preset value as described, judges that battery capacity is low, otherwise then judge battery capacity just
Often.
With reference to Fig. 2 of the invention, it can be seen that preferably, battery capacity detector also includes a timing circuit, itself and institute
State dynamic detection loop be arranged in parallel for carry out indicate loop 3 delays time to control.
In addition, in the present invention, preferably, the instruction loop 3 may particularly include for indicating respectively putting for battery
The indicator lamp 5 of electricity condition, under-voltage condition or normal condition.The indicator lamp can set different colors according to different battery status
To show differentiation, for example, red, green or colorful light emitting diode.
Furthermore, present invention also offers a kind of battery capacity check method, the method includes：
Step 1, measures the voltage rate of descent of mesuring battary；
Step 2, the voltage rate of descent is compared with preset value, and voltage rate of descent is more than preset value as described, sentences
Power-off tankage is low, otherwise then judges that battery capacity is normal.
Specifically, application method step can refer to as follows：
First, lithium battery to be measured is put into testing cassete.
2nd, battery capacity detector is connected 220V civil powers.
3rd, detection triggering key is clicked, detector enters detection state, discharge indicating lamp flicker.
4th, it is interior during detecting, if when red, then it represents that the battery has failed, this detection should be terminated, method is to pull out
Lower attaching plug, removes tested battery.
5th, after detection terminates (about 5 minutes), green light is still lighted, and shows that the lithium battery is functional, and can trust makes
With.
6th, it is detected battery of good performance and answers timely boost charge.
1st, it is interior during detecting, if normal lamp is bright (such as Fig. 1), and after detection terminates (about 5 minutes), normal lamp according to
It is so bright, show that the lithium battery is functional, can be safe to use.
2nd, it is interior during detecting, if under-voltage lamp is bright (such as Fig. 2), then it represents that the battery has failed, this detection should be terminated,
Method is to pull up attaching plug, removes tested battery.
Above example is only exemplary embodiment of the invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make respectively in essence of the invention and protection domain to the present invention
Modification or equivalent are planted, this modification or equivalent also should be regarded as being within the scope of the present invention.
