(20)It is interior to be provided with hourglass hole area control sheet U-type groove(19), hourglass slippage slot supporting plate(25)It has been embedded in hourglass slippage slot support
Plate hourglass hole area controls U-type groove(18), hourglass slippage slot supporting plate hourglass hole area control U-type groove(18)Stacking is placed in
Hourglass hole area control sheet U-type groove(19)On, when both occur relative motion, hourglass hole area changes.
Current integration hourglass(26)Overall embedded battery bag casing(1)Outer wall on.
Voltage-stabiliser tube pair(14)Conducting voltage threshold value be higher than battery quiescent voltage.
Battery bag casing is provided with battery bag roof box(2), the ventilative base of battery bag casing(3), air-permeating hole(4), electricity
Pond group bottom end cover(5), battery bag box bottom(6), cell(7), battery pack sleeve(8), battery pack upper end cover(9), heat
Convection ventilation window mouthful(10);Battery bag roof box(2)With battery bag box bottom(6)Battery pack bottom end cover(5)And battery
Group upper end cover(9)Between battery pack sleeve is installed(8), sleeve pipe is built with cell(7), battery pack upper end cover(9)Top is set
Put thermal convection current ventilation window(10), battery bag casing bottom sets the ventilative base of battery bag casing(3)And air-permeating hole(4), battery
Group sleeve pipe(9)Inwall and cell(7)There is bar in battery pack sleeve between outer wall so that battery pack sleeve(9)Inwall and monomer
Battery(7)There is gap between outer wall, gap is more than 0.1 millimeter, the sleeve pipe close-packed arrays of battery pack, every 8 sleeve pipe battery packs
Constitute a measuring unit.
Operation principle:The positive electrode current output conductor wire of Battery case is divided into two-way, is all the way DC output end, concatenation electricity
Streamline circle(23)Afterwards to loading, another road concatenates divider resistance R(11), adjustable resistance(12), led lamp beads(16)With positive and negative concatenation
Voltage-stabiliser tube pair(14)Concatenate a potential winding again afterwards(15)To negative pole end.Therefore, current coil is concatenated(15)In electric current just
Than the electric current that load is terminated in direct current output.And the life-span of battery is closely bound up with output input current, charge each time
Life-span with discharge battery is all in decay, therefore we may determine that the life-span of this battery using this characteristic, particularly
It is serious to the injury of battery for high current charge-discharge, has a strong impact on the life-span of battery, and the discharge and recharge of this high current
It is that judgement can not be realized by kilowatt-hour meter, because influence of the high current to battery life is nonlinear, rather than linear superposition.
Because output input current is proportional to current coil(23)Electric current, then electric current is bigger, and magnetic field is stronger.One end of electromagnet
It is implanted into hourglass slippage slot supporting plate(25)Right-hand member iron core sliding cavity(24)Interior, the left end of the cavity is provided with hourglass hole area control
System is unshakable in one's determination(21), hourglass hole area control iron core(21)With hourglass hole area control sheet(20)It is connected, hourglass hole
Area control piece(20)It is interior to be provided with hourglass hole area control sheet U-type groove(19), hourglass slippage slot supporting plate(25)It has been embedded in sand
Leak slippage slot supporting plate hourglass hole area control U-type groove(18), hourglass slippage slot supporting plate hourglass hole area control U-type groove(18)
Stacking is placed in hourglass hole area control sheet U-type groove(19)On, when both occur relative motion, hourglass hole area hair
Raw to change, this special structure make it that when electric current changes, the area of hourglass hole can change, Wo Menye
Can be according to the non-linear relation characteristic of battery life and electric current, design changes the control of hourglass slippage slot supporting plate hourglass hole area
U-type groove(18)With hourglass hole area control sheet U-type groove(19)Shape so that hourglass hole area and electric current are constituted to each other
The situation of non-linear relation, simulation high current and battery life, finally realizes and judges electricity by the hourglass of a very low cost
The life-span in pond.
Influence of the voltage to battery life.Consider another road concatenation divider resistance R(11), adjustable resistance(12), led lamp beads
(16), it is positive and negative concatenation voltage-stabiliser tube pair(14)Concatenate a potential winding again afterwards(15)To negative pole end.When discharge and recharge, especially
It is when charging, if overtension, influence also to be produced on the life-span of battery, therefore be also contemplated that high voltage to battery
The influence in life-span.Due to being provided with positive and negative voltage-stabiliser tube pair(14), the conducting voltage threshold value of the voltage-stabiliser tube pair is higher than battery tension,
Therefore when battery discharge, this route road is no electric current;If one high voltage of input is charged, this when
Influence will be produced on the life-span of battery, charging voltage threshold value is higher than voltage-stabiliser tube pair(14)Conducting voltage threshold value, the road electricity
Road is powered, and electric current passes through potential winding(15), produce magnetic field, on the other hand, current coil(23)Also magnetic field, two magnetic fields are produced
It is overlapped so that ferromagnet(22)Magnetic force becomes strong, and its course of work is same as described above, and hourglass hole area changes.I
The non-linear relation constituted can also be integrated according to battery life and voltage, electric current, it is husky that design changes hourglass slippage slot supporting plate
Small opening hole area control U-type groove(18)With hourglass hole area control sheet U-type groove(19)Shape so that hourglass hole to each other
Area constitutes the situation of non-linear relation, simulation high-voltage charge and battery life with electric current, finally realizes extremely low by one
The hourglass of cost judges the life-span of battery.
Two kinds of situations of summary, it is possible to more accurately judge the life-span of battery.
Battery bag roof box(2)With battery bag box bottom(6)Sleeve pipe fixation hollow round platform(19)Position is coaxially right
Should, battery pack sleeve is installed between two round platforms(9), sleeve pipe is built with cell(7), battery pack sleeve(9)Inwall and list
Body battery(7)There is bar in battery pack sleeve between outer wall(11)So that battery pack sleeve(9)Inwall and cell(7)Outer wall it
Between there is gap, gap is more than 0.1 millimeter, the sleeve pipe close-packed arrays of battery pack, and it is single that every 8 sleeve pipe battery packs constitute a measurement
Member, the battery anode electric current output conductor wire of each battery cartridge, such structure contributes to radiating.For battery radiating
For, when battery-heating amount is less, the temperature and circumstance of temperature difference of inside battery are smaller, but in general environment temperature will
Height, the air of cell meeting circumference, exist because cell is among sleeve pipe, between battery giant's pipe again between
Gap, then just generates thermal convection current phenomenon, and hot-air rises, and it is next that cold air has bottom to be supplemented in, and air-flow is formed, timely list
Body battery(7)The heat of surrounding is taken away, from thermal convection current ventilation window(10)Discharge so that the heat in battery bag is distributed in time,
Heat accumulation effect will not be produced so that the temperature limiting of battery is within the scope of one rational.Such structure can arbitrarily more
Change the cell of battery bag.
Beneficial effect:The present invention can be designed according to relation property between battery life and electric current and voltage and change hourglass
Slippage slot supporting plate hourglass hole area controls U-type groove(18)With hourglass hole area control sheet U-type groove(19)Shape so that
Hourglass hole area constitutes the situation of non-linear relation, simulation high current and battery life with electric current around here, and so we can
To judge the life-span of battery by observing the hourglass of a very low cost.Present invention, avoiding complicated circuit structure, have
Wide application prospect and market prospects.
