Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is described in further detail.
According to the characteristic of lead-acid accumulator itself, in its discharge process, produced polarization has with the size of discharge current
Closing, lead-acid accumulator discharges into identical final voltage, and discharge capacity is then relevant with discharge current size.As by lead-acid accumulator
The order gradually successively decreased according to discharge current is discharged successively, before the capacity released with big discharge current with put with small area analysis below
The capacity gone out adds up basically identical with the capacity released with small area analysis completely.According to above-mentioned principle, the present invention provides a kind of
The checking of lead-acid accumulator constant-current discharge current parameters and method of testing, to realize utilizing a lead-acid accumulator, i.e. can verify that
And discharge current parameter during at least two constant-current discharges of test.
Embodiment one
Refer to Fig. 1, in the present embodiment, the verification method step of lead-acid accumulator constant-current discharge current parameters is as follows:
By N number of discharge current value of to be verified and corresponding same final voltage according to the order sequence successively decreased successively, each
An individual discharge current value corresponding electric discharge standard time；
Lead-acid accumulator carries out n times constant-current discharge successively by the discharge current value of arrangement of successively decreasing, and obtains the most N number of
Single step discharge capacity；
N number of single step discharge capacity is added up, obtains accumulated discharge total capacity；
The discharge current to be verified of correspondence of discharging divided by n-th with accumulated discharge total capacity, the electric discharge obtaining n-th is changed
Evaluation time；
Electric discharge Extrapolation time was compared with the corresponding electric discharge standard time, whether to verify the discharge current of n-th
Rationally.In general, when calculated electric discharge Extrapolation time is not less than the electric discharge standard time, and less than the electric discharge standard time
110%, the discharge current of n-th the most to be verified is rational, and otherwise, the discharge current of n-th to be verified is unreasonable
's.
Preferably, when verifying according to above-mentioned steps, also need:
Record every time electric discharge reaches the single step discharge time after corresponding final voltage, with according to single step discharge time with corresponding
The amassing of constant-current discharge electric current obtains single step discharge capacity；
Every time after discharge off, lead-acid accumulator discharges after need to standing 5～10 minutes the most next time；
Before completing n times constant-current discharge, lead-acid accumulator is not mended electricity.
Below, as a example by the lead-acid accumulator of 12V100AH, discharge current ginseng during constant-current discharge in the present embodiment is described
The verification method of number.Ask for an interview table 1, when dispatching from the factory for the lead-acid accumulator of this model, the specification table of discharge current parameter to be verified, should
Table only lists part discharge current to be verified and corresponding final voltage and the electric discharge standard time is for reference, wherein, permanent
Final voltage when banishing electricity and electric discharge standard time are all known specification value, and discharge current to be verified is that tester combines reality
In many ways the values that factor is drafted such as border situation, test experience and vendors dictate.
Table 1
Here, illustrate to carry out discharge current ginseng according to the verification method in the present embodiment as a example by final voltage is 1.75 volts
The proof procedure of number and result.
First, by 15 discharge current values to be verified according to the order sequence successively decreased successively, then the specification is selected to be
The lead-acid accumulator of 12V100AH, is allowed to the discharge current value order according to successively decreasing successively and carries out 15 constant-current discharges, each time
After constant-current discharge, this lead-acid accumulator stands after 5～10 minutes and carries out constant-current discharge next time, complete 15 constant-current discharges it
Before do not carry out this lead-acid accumulator mending electricity, during electric discharge, record the single step after every time electric discharge reaches final voltage 1.75 volts and put
The electricity time, to obtain single step discharge capacity according to single step amass with discharge current during corresponding constant-current discharge discharge time, certainly,
Single step discharge capacity can also utilize instrument directly to record during each constant-current discharge, now, and constant-current discharge process
In single step discharge time then without record, specifically ask for an interview table 2.Pacify whether to meet to checking discharge current 202.3 and newly dispatch from the factory
The regulation of lead-acid accumulator, needs first the single step discharge capacity recorded to be added up, i.e. with 16.1AH plus 14.9AH, it
After add 11.1AH, the most again with 11.1AH be added, obtaining accumulated discharge total capacity is 53.1AH, thus, calculates
Extrapolation time is that 53.1AH pacifies divided by 202.3, is 15.8 minutes.If other discharge currents need to be verified, it is only necessary to the most former
Reason is carried out.
Here, for the ease of contrasting with traditional verification method, table 2 is also chosen six discharge currents according to tradition side
Method is verified, and single battery discharge time checking drawn is listed respectively.Traditional verification method is: select six homotypes
The lead-acid accumulator of number (12V100AH), the discharge current that first battery needs checking is 202.3 peaces, with this discharge current pair
The final voltage answered is 1.75 volts, and the standard time is 15 minutes, during test, when discharge voltage reaches final voltage 1.75 volts,
This battery i.e. stops electric discharge, and when now corresponding discharge time is 15.9 minutes, this obtains with the verification method according to the present embodiment
To result be sufficiently close to；Equally, second battery needs the discharge current tested to be 128.8 peaces, corresponding discharge off electricity
Pressure is 1.75 volts, and the standard time is 30 minutes, and during test, when discharge voltage reaches final voltage 1.75 volts, this battery i.e. stops
Only electric discharge, now corresponding discharge time is 30.6 minutes, is obtained by other several battery testing correspondences in the same way
Discharge time during discharge current, ask for an interview last perpendicular hurdle of table 2.More i.e. can be seen that, the Extrapolation time that the present embodiment draws with
Single battery discharge time difference is not very big, and this explanation, the verification method described in the present embodiment has feasibility.
