With reference to the accompanying drawing, for the device of the invention to the course of work of the charging of battery, detection and maintenance management
It is described in detail.
1, charge function: the present apparatus carries out battery using the intelligent multi-control accumulator charging control method based on capacity
Charging.According to battery types and model, the charging stage that the present apparatus can be different in battery is charged using intelligent multi-control and is controlled
Method processed, so that practical charging process is close or equal to battery optimal charge curve always.By 81 basis of processor unit
Battery status selects normal or emergent charging mode and exports charging instruction, the optocoupler array element 52 through isolation drive module 5
Export makes it obtain gate source voltage to high-power MOS tube 51 is connected, treated D/ of the signal as charge control module 2
The input of A converting unit 21, the analog signal of the voltage and current obtained after conversion is after the adjustment of PID adjustment unit 22, through driving
Control unit 23 is moved to drive the high-frequency inversion unit 14 of charging power modules 1, by changing reverse frequency and duty ratio in real time
To realize that different mode charges；By the selection of power supply switch unit 11 exchange or direct current input, EMI filter unit is used to change
Kind input power performance is then converted to direct current as high-frequency inversion unit 14 through AC/DC converter unit 13 if it is exchange input
Input, if it is direct current input high-frequency inversion unit 14 is then directly inputted after pressure stabilizing；The controllable high-frequency alternating current warp of frequency
High frequency transformer 15 obtains high voltagehigh frequency alternating current, and rectified/filter unit 16 inputs the protective module 6 of battery, passes through temperature
Spending protection location 61, over-current protecting unit 62, Overvoltage protecting unit 63, reverse connecting protection unit 64, short-circuit protection unit 65 is to store
Battery provides charging current.
Meanwhile the battery status that the present apparatus needs real-time detection unknown, special control of discharge module 3 is needed thus.?
Under the unified timing effect of timing control unit 82, the electronic load 31 based on charge pump is devised, according to variety classes battery volume
Constant volume selects discharge current, implements the operation such as heavy-current discharge and storage electric discharge to battery through electric discharge copper resistance 32, to store
The capacity check of battery, battery maintenance provide support.
2, detection function: the detection function of battery is mainly used for state-detection and capacity check to battery.
The state-detection of battery mainly realizes the acquisition of its status information during the filling, put of battery, including electric power storage
Cell voltage, electric current and temperature information.Current acquisition unit 41, voltage acquisition unit 42 and temperature collecting cell 43 acquire storage respectively
Current information, information of voltage and the temperature information of battery, collected current information, information of voltage and temperature information are single through filtering
Enter the light in isolation drive module 5 after the A/D conversion of the filtering of member 71, the amplification of amplifying unit 72 and A/D converting unit
Then coupling array element 52 is re-fed into processor unit 81 and is handled and be supplied to maintenance terminal to realize electrical isolation
83 use.
The capacity check of battery can detecte out the actual capacity of battery, predict its service life cycle and remaining appearance
Amount, provides judgement to its state, provides foundation for the replacement of battery.When battery capacity detects, divide three phases to complete, the
One stage: it is discharged using control of discharge module 3 battery；Second stage: using charging power modules 1 to battery into
Row recharges, until being completely filled with；Phase III: can obtain the capacity of battery with the time multiplied by size of current, store
Battery actual capacity overhaul flow chart is as shown in Figure 3.
When battery capacity detects, after system initialization, whether detection cell voltage size first is less than rated value (battery
Rated capacity), if it is less than rated value, then integrating electric is calculated multiplied by time value, the value obtained is that battery actual capacity is big
It is small.If detecting battery voltage value is greater than rated value, after carrying out electric discharge a period of time t to battery, size of current is then detected,
Then whether detection cell voltage size is less than rated value again, repeatedly, until detecting that cell voltage is less than rated value
Until.The temperature information of battery is transmitted to processor unit 81 and judges whether excess temperature, if excess temperature, is carried out by maintenance terminal 83
Alarm, and it is automatically stopped charge or discharge process.
3, maintenance management function: by detecting to battery, providing storage discharging function, can be long-term in battery
It is discharged into suitable voltage when not used, it is made to be stored in Optimum storage state, is conducive to extend the service life of battery；It stores simultaneously
The access times of battery, performance parameter establish database, and database is stored in maintenance terminal 83, by database
The status information of every group of battery can select the battery of different stage according to different application.
In conclusion can adapt to a variety of the present invention provides a kind of detection of intelligent accummulator and charge maintenance device
Class battery, and the function of charging to battery, detection, maintenance management is had both, extend the service life of battery.
