Abstract
The invention relates to a method for inspecting the deterioration of a battery and its residual capacity, and the apparatus therefor. In the method, a load is connected with a battery (1) to be inspected, and the current corresponding to its capacity is made to flow through it. Then, by monitoring the change of the terminal voltage (V) of the battery (1) for a predetermined time, judged is the deterioration of the battery (1) according to the change. From the terminal voltage (V) of the battery (1), judged is the residual capacity of the battery (1). Further, the results of the judgement thereof are displayed on a displaying means. Thereby, the deterioration of the battery and its residual capacity can be grasped easily and surely, and they can be confirmed with the display immediately.
Description
The present invention relates to be used to check the accumulator inspection method and the device thereof of accumulator degree of aging and residual capacity.
Usually, the capacity of accumulator is stipulated with ampere hour (Ah) capacity and time rate (hourrate).For example capacity is that the accumulator of 10Ah/10 time rate only has the ability that flow through the 1A steady current in 10 hours.
The 6th illustrates the desirable discharge characteristic curve 30 of 12V accumulator.According to this figure, the terminal voltage of accumulator is from the moment T that is full of electricity of 12.6V
1The moment T of having put electricity to 10.6V
2Almost keep smooth state, one crosses the moment T of having put electricity
2Just descend sharp.
Illustrated discharge characteristic curve 30 is curves of deferring to aforesaid time rate discharge.If for example make the current discharge of the accumulator of 10Ah/10 time rate with 10A, then the time that can use is just less than 1 hour, and accumulator will become the state of having put electricity through about 30 minutes, and discharge characteristic curve also becomes irregular.
Although can know the residual capacity of accumulator, because terminal voltage does not descend under light condition, so even measured the residual capacity that the terminal voltage of accumulator can not be known accumulator in this state according to the terminal voltage of accumulator.
In addition, accumulator can be aging through long-term the use.Accumulator is in a single day aging, just can not obtain smooth discharge characteristic curve 30 as shown in the figure, thereby need more renew battery.
Now, just when reality is used accumulator, according to the time that may use with the degree of aging of feeling to judge accumulator.But, since the time that may use change with the size of discharge current, so with this with can not the judge rightly degree of aging of accumulator of the method for feeling.
The present invention is conceived to the problems referred to above, and purpose provides can be correctly and grasp the accumulator inspection method and the device thereof of accumulator degree of aging and residual capacity easily.
The accumulator inspection method of inspection accumulator degree of aging of the present invention is to be undertaken by the variation of current supply being measured its terminal voltage time the accumulator, it is characterized in that the following step:
(a～d) then is identified for discerning described discharge characteristic curve (the terminal voltage determinating reference value (V of a～d) of each different schedule time to verify the discharge characteristic curve that expression changes for the terminal voltage of the accumulator of a period of time through having later different degree of agings

3);
Supply the accumulator that current supply is arrived examine with the corresponding electric current of described accumulator capacity by connecting load, follow each process moment of the described schedule time that begins in the initial moment, with the terminal voltage (V) and the described determinating reference value (V of accumulator from supplying electric current
1～V
3) compare;
Utilize above-mentioned each comparative result constantly judge examine described accumulator discharge characteristic curve whether with described battery with different degree of agings in any discharge characteristic curve corresponding; And
Discern the degree of aging of the accumulator of described examine according to described judged result.
The present invention is used to check that the accumulator testing fixture of accumulator degree of aging comprises that one is used for the power-on circuit of current supply accumulator, is used for judging by the terminal voltage (V) of measuring described accumulator in supply power the judgment means of described accumulator degree of aging, and an output unit that is used for transmitting to the outside described judged result, it is characterized in that:

Like this, read individual decision data A
1～A
3The time, in step 9, controller 18 is just carried out (the step 9-1～9-10), judge the degree of aging of accumulator 1 of the control sequence shown in the 5th figure.In step 10, after inspection finishes, judge whether reset button switch 14 is pressed, if this judgement is " YES ", then controller 18 just makes the timing action stop (step 11) to timer 4 output stop signals.
In the 5th figure, controller 18 goes out data A at step 9-1 from aforementioned memory read
1～A
3, judge the degree of aging of accumulator 1 according to the formation of its data.
If decision data A
1～A
3All be logical one, then at this moment being judged as of step 9-2 " YES " just judged that checked accumulator 1 is not aging desirable accumulator, and made the luminophor 10 of expression " excellent " light (step 9-3).
If decision data A
1Be logical zero, remaining decision data A
2, A
3Be logical one, then being judged as of step 9-4 " YES " at this moment, just judged that checked accumulator 1 is almost not aging good accumulator, and made the luminophor 10 of expression " very " light (step 9-5).
If decision data A
1, A
2All be logical zero, remaining decision data A
3Be logical one, then being judged as of step 9-6 " YES " at this moment, just judged that checked accumulator 1 is the accumulator that is wearing out, and made the luminophor 10 of expression " attention " light (step 9-7).
If decision data A
1～A
3All be logical zero, at this moment being judged as of step 9-8 " YES " then, just judge that checked accumulator 1 is the aging accumulator changed of seriously needing, and the luminophor 10 that expression " will be changed " is lighted (step 9-9).
If decision data A～A
3All inequality with above-mentioned any situation, then can not judge, at this moment, adopt modes such as for example making all luminophors 10 flicker certain hours to represent (step 9-10).
