Device, square lithium ion battery and the visual identification side in the service life of visual identification lithium-ion electric core described in the present embodiment
The principle of method are as follows: for a part of service life of lithium battery comprehensive tester, the internal resistance of lithium battery is important evaluation index, in lithium ion
In the use process of battery, internal resistance can constantly become larger, and (damage of positive and negative anodes structure increases internal resistance, and the active reduction of electrolyte increases
The film forming repeatedly of internal resistance, SEI film increases internal resistance).According to previous experiences data, (capacity drop at the end of lithium battery cycle life
To 80%), internal resistance can increase to 2 times or more, so the core content that the present invention monitors, the i.e. variation of the internal resistance of cell.Pass through
The use of simple resistor component reaches the monitoring to battery core internal resistance and effect of visualization.Referring to fig. 4 and shown in Fig. 5, wherein
Resistance of the Rcold for low temperature threshold switch, resistance of the Rheat for high temperature threshold switch, Rlife1, Rlife2, Rlife3 are
Service life shows that the resistance of fusing resistor, Rbattery are the internal resistance of lithium-ion electric core.The device is integrated to PCB using resistive element
The mode of plate is realized, is consisted of two parts: on-off automatic control module, service life display module.On-off automatic control module first
A element is that cold memory metal (can bend in the lower situation of temperature, disconnect circuit, temperature is restored again after restoring
Rectilinear configuration), the effect of the element is lithium ion battery at low ambient temperatures, and resistance can become larger, at this time if do not turned off back
Road can be such that service life display device judges by accident, that is, the device is avoided to work at low ambient temperatures.Second element is heat memory gold
Belonging to (can bend in the case where itself is got higher by the longer temperature of current time, circuit be disconnected, after temperature is restored
Again restore rectilinear configuration), the effect of the element is that service life display has bypassed electric current and can consume the additional energy of battery core and (is less than
1%) it, so working condition should not be in for a long time, should just be disconnected after the completion of monitoring.It is certain by service life display module in electric current
(it is less than 30s) after time, since electric current flows through conductor temp.-elevating, disconnects entire circuit, avoids continuing loss of energy.Service life display
Module can be made of (resistance value is from low to high) the different fuse of multiple resistance values, and whole device is in parallel with battery core, when in battery core
When resistance increases, the electric current for flowing through fuse accordingly be will increase, then blowout, pass through the different blowout of height
Situation, it can be determined which stage the battery core service life is in.For example, charging process total voltage is U, internal resistance of cell Rb, the service life is aobvious
Show that fuse resistance is Rlife=100Rb (has bypassed the 0.91% of total current) at this time.When the service life is 100%, Ib=U/
Rb, Ilife=U/Rlife=U/100Rb=0.01Ib, the electric current for flowing through longevity aobvious resistance at this time is Ilife；When the service life is 0%, electricity
Pond internal resistance becomes 2Rb, in electric current IbIn the case where remaining unchanged, voltage becomes 2U, and the electric current for flowing through longevity aobvious resistance at this time becomes1 times is increased, can be with fusing resistor, by direct visual perception, that is, visual variation can be observed, and (resistance can
To use colored designs, color lump disappears after fusing, it will be apparent that).It is similarly shown for the different service life, can select to melt respectively
Power-off stream is 1.2 times of standard, 1.5 times, 2 times, that is, realizes the display to different lifetime stages.It is illustrated with actual product.Certain
Square battery core, factory internal resistance are 10m Ω, and standard is 20A using lower maximum current.By test, service life is respectively reached
20%, 50%, 100% when, corresponding internal resistance be 12m Ω, 15m Ω, 20m Ω.It is corresponding resistance value is equipped with to it to be, 1.2 Ω,
The fusing resistor of 1.5 Ω, 2 Ω, corresponding blowout current are 240mA, 300mA, 400mA.In use, with its battery core
Aging, internal driving are gradually increased, and corresponding service life shows fusing resistor, is each turned off, and are represented its service life and are gradually terminated.
Device, square lithium ion battery and the visual identification side in the service life of visual identification lithium-ion electric core described in the present embodiment
Method, low in cost, the material used is temperature memory metal (fuse of many Reusabilities is the material at present) and mark
