Accordingly, it is desirable to provide a kind of battery performance measuring instrument solves the problems referred to above.
Utility model content
In order to solve this problem, the utility model discloses a kind of battery performance measuring instrument, it is easy to use,
Highly sensitive, service life is long, practical.A kind of battery performance measuring instrument, it includes, power supply mould
Block (1), CPU module (2), bang-bang circuit (3), radiating module (4), detection module (5)
With display module (6), it is characterised in that: described power module (1) is connected with CPU module (2),
And CPU module (2) the most respectively with bang-bang circuit (3), radiating module (4) and detection module (5)
Connect；Described detection module (5) is connected with display module (6).
The beneficial effects of the utility model are: this utility model is easy to use, highly sensitive, service life
Long, practical.
In conjunction with advantage of the present utility model described further below and feature.
Accompanying drawing explanation
Fig. 1 is organizational structure schematic diagram of the present utility model；
Detailed description of the invention
In the following description, a large amount of concrete details is given to provide the most thorough to this utility model
The understanding at the end.It will be apparent, however, to one skilled in the art that this utility model is permissible
It is carried out without these details one or more.In other example, in order to avoid with this practicality
Novel obscure, technical characteristics more well known in the art are not described.
In order to thoroughly understand this utility model, detailed structure will be proposed in following description.Obviously,
Execution of the present utility model is not limited to the specific details that those skilled in the art is familiar with.This practicality
Novel preferred embodiment is described in detail as follows, but in addition to these describe in detail, this utility model is also
Can have other embodiments.
Hereinafter embodiment of the present utility model is described in detail.
With reference to Fig. 1, a kind of battery performance measuring instrument, it includes, power module (1), CPU module (2),

Be: described power module (1) is connected with CPU module (2), and CPU module (2) the most respectively with
Bang-bang circuit (3), radiating module (4) and detection module (5) connect；Described detection module (5)
It is connected with display module (6).
The using method of the present embodiment is:
When battery and external power adapter are soldered or are plugged on battery interface, after turning on the power switch,
By Control battery, load is discharged；In discharge process, control fan and open, dissipate
Heat, when cell voltage is reduced to below 3.0V, has illustrated first run battery discharge.It is complete right to start
The testing process of battery is as follows:
1. step up battery charge, during to maximum charging current, record what this battery can be supported by
Maximum charging current, completes charging current scanning record；
2. with maximum charging current, battery is charged, when cell voltage reaches more than 4.1V, is not sending out
During changing, complete charging, record the charging interval；
3. the electric current of pair charging process is integrated, and calculates charge capacity total value record；
After the most fully charged, switch relay, start battery is discharged；
5. incrementally increase discharge current, when cell voltage drops suddenly, obtain maximum discharge current record；
6. discharge with the 90% of maximum discharge current pair of battery, when cell voltage drops to below 3.0V,
Complete discharge process, discharge current is integrated, obtain discharge capacity of the cell；
7. complete more than 10 times charge and discharge process, by epitaxy, by the entirety of above parameter evaluation battery
Life-span.
8. pair battery needed, can do the battery charge and discharge process of more than 500 times, the last residue of assessment
Battery electric quantity, see and whether reach the 50% of initial cells electricity.
9. can pass through switch key, LED checks battery capacity, battery charge time, battery discharge
The parameters such as maximum current, battery chargeable number of times (battery life).
Having the beneficial effect that of the present embodiment
This utility model is easy to use, highly sensitive, and service life is long, practical.
This utility model is illustrated by above-described embodiment, but it is to be understood that, above-mentioned reality
Execute example and be only intended to citing and descriptive purpose, and be not intended to be limited to this utility model described reality
In the range of executing example.In addition on it will be appreciated by persons skilled in the art that this utility model is not limited to
Stating embodiment, can also make more kinds of variants and modifications according to teaching of the present utility model, these become
Within type and amendment all fall within this utility model scope required for protection.Protection domain of the present utility model
Defined by the appended claims and equivalent scope thereof.
