Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the modular structure schematic diagram of a kind of specific embodiment of battery-detecting instrument of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of battery-detecting instrument, it comprises: shell (not shown), the power module 11, operational module 12, communication module 13, constant-current discharge module 14 and the display module 15 that in described shell, be provided with microprocessor 10, are electrically connected respectively with microprocessor 10, described communication module 13 and constant-current discharge module 14 one end are electrically connected with a battery module 20 respectively.Battery-detecting instrument of the present utility model, it can be according to the capacity of accumulator, discharge current is reasonably set, be arranged under nominal discharge current condition and discharged, and adopt constant-current discharge method, therefore can imitated storage battery continuous firing under rated power, can embody the most really the true residual capacity of accumulator.
Wherein, can to adopt model be the single-chip microcomputer of STC89C58RD+ to described microprocessor 10.This STC89C58RD+ is a more single-chip microcomputer that uses in industrial control process, and it is the single-chip microcomputer of single clock/machine cycle (1T), and the fast 8-12 of more common 51 single-chip microcomputer of picking rate doubly.In the utility model specific embodiment, the AD sample circuit (not shown) that is provided with current/voltage conversion chip in described microprocessor 10 and is electrically connected with this current/voltage conversion chip.As a kind of selectivity embodiment of the present utility model, it is the chip of MAX4080 that described current/voltage conversion chip can adopt model, and take current conversion is voltage, and after AD sample circuit, calculates enforcement electric current.
Moreover described shell is provided with panel, operational module 12 comprises that several being located at control button (not shown) on panel, and these several buttons of controlling are electrically connected with microprocessor 10 respectively.
Optionally, constant-current discharge module 14 in the utility model can adopt integrated operational amplifier to form storage battery constant-current discharge circuit, by microprocessor 10, discharge current is reasonably set, by its its, be arranged under nominal discharge current condition and discharge, and adopt constant-current discharge method, this can imitated storage battery continuous firing under rated power, can embody the most really the true residual capacity of accumulator.Can arrange every 1S and carry out an AD sampling, after 20S is to result value of averaging of 20 samplings, carry out the capacity that Integral Processing obtains emitting within 20S, by that analogy, until electric discharge finishes, obtain final capacity information, the rear automatic disconnection electric discharge of having discharged.The capacity precision that adopts said method to obtain can reach 0.001AH.
Concrete, described display module 15 can be for being installed on the liquid crystal display on panel, and this liquid crystal display can show in real time to the time of the capacity information of battery module 20, electric current, voltage and electric discharge.
