Kodi moduli ya batri ya lithiamu ndi chiyani?

Chidule cha ma module a batri

Ma module a batri ndi gawo lofunikira pamagalimoto amagetsi.Ntchito yawo ndikugwirizanitsa maselo ambiri a batri pamodzi kuti apange lonse kuti apereke mphamvu zokwanira kuti magalimoto amagetsi azigwira ntchito.

Ma module a batri ndi zigawo za batri zomwe zimapangidwa ndi maselo ambiri a batri ndipo ndizofunikira kwambiri pamagalimoto amagetsi.Ntchito yawo ndikugwirizanitsa maselo ambiri a batri palimodzi kuti apange zonse kuti apereke mphamvu zokwanira zamagalimoto amagetsi kapena ntchito zosungira mphamvu.Ma modules a batri sikuti ndi mphamvu yokha ya magalimoto amagetsi, komanso imodzi mwa zipangizo zawo zofunika kwambiri zosungira mphamvu.

Kubadwa kwa ma module a batri

Kuchokera pamalingaliro amakampani opanga makina, mabatire a cell imodzi ali ndi zovuta monga kusagwira bwino kwamakina ndi mawonekedwe akunja osachezeka, makamaka kuphatikiza:

1. Maonekedwe akunja a thupi monga kukula ndi maonekedwe ndi osakhazikika, ndipo adzasintha kwambiri ndi ndondomeko ya moyo;

2. Kupanda kosavuta ndi kodalirika makina kukhazikitsa ndi kukonza mawonekedwe;

3. Kupanda yabwino linanena bungwe kugwirizana ndi udindo polojekiti mawonekedwe;

4. Chitetezo chofooka cha makina ndi kutchinjiriza.

Chifukwa mabatire a selo limodzi ali ndi mavuto omwe ali pamwambawa, m'pofunika kuwonjezera wosanjikiza kuti asinthe ndi kuwathetsa, kotero kuti batire ikhoza kusonkhanitsidwa ndikuphatikizidwa ndi galimoto yonse mosavuta.Ma module omwe amapangidwa ndi mabatire angapo mpaka khumi kapena makumi awiri, okhala ndi mawonekedwe okhazikika akunja, osavuta komanso odalirika makina, linanena bungwe, mawonekedwe oyang'anira, ndi kutetezedwa kwamphamvu komanso chitetezo chamakina ndi chifukwa cha kusankha kwachilengedwe.

Ma module apano amathetsa mavuto osiyanasiyana a mabatire ndipo ali ndi maubwino awa:

1. Imatha kuzindikira mosavuta kupanga makina ndipo imakhala ndi magwiridwe antchito apamwamba, ndipo mtundu wazinthu ndi mtengo wopanga ndizosavuta kuziwongolera;

2. Ikhoza kupanga digiri yapamwamba yokhazikika, yomwe imathandizira kuchepetsa kwambiri mtengo wa mzere wopanga ndikuwongolera kupanga bwino;mawonekedwe ofananirako ndi mafotokozedwe amathandizira kuti pakhale mpikisano wamsika wathunthu ndikusankha njira ziwiri, ndikusunga magwiridwe antchito bwino a kagwiritsidwe kake;

3. Kudalirika kwabwino, komwe kungapereke chitetezo chabwino chamakina ndi kutchinjiriza kwa mabatire nthawi yonse ya moyo;

4. Kutsika mtengo kwazinthu zopangira sikungakhazikitse kukakamizidwa kwambiri pamtengo womaliza wamagetsi;

5. Mtengo wocheperako wokhazikika wa unit ndi wocheperako, womwe umakhudza kwambiri kuchepetsa ndalama zogulitsa pambuyo pogulitsa.

Kapangidwe ka batire module

Kapangidwe ka batire module nthawi zambiri kumaphatikizapo batire cell, kasamalidwe ka batire, bokosi la batri, cholumikizira batire ndi magawo ena.Battery cell ndiye gawo lofunikira kwambiri pa module ya batri.Amapangidwa ndi mayunitsi angapo a batri, nthawi zambiri batri ya lithiamu-ion, yomwe imakhala ndi mawonekedwe amphamvu kwambiri, kutsika kwamadzimadzi komanso moyo wautali wautumiki.

Dongosolo loyang'anira batire lilipo kuti zitsimikizire chitetezo, kudalirika komanso moyo wautali wa batri.Ntchito zake zazikulu zikuphatikiza kuwunika momwe mabatire amakhalira, kuwongolera kutentha kwa batri, kuchulukitsa kwa batri / kuteteza kutulutsa, ndi zina zambiri.

Bokosi la batri ndi chipolopolo chakunja cha batri, chomwe chimagwiritsidwa ntchito kuteteza gawo la batri ku chilengedwe chakunja.Bokosi la batri nthawi zambiri limapangidwa ndi chitsulo kapena pulasitiki, kukana kwa dzimbiri, kukana moto, kukana kuphulika ndi zina.

Cholumikizira batri ndi gawo lomwe limalumikiza ma cell angapo a batri kukhala athunthu.Nthawi zambiri amapangidwa ndi zinthu zamkuwa, zokhala ndi conductivity yabwino, kukana kuvala komanso kukana dzimbiri.

Zizindikiro za magwiridwe antchito a batri

Kukaniza kwamkati kumatanthawuza kukana kwaposachedwa kumayenda kudzera mu batire pamene batire ikugwira ntchito, yomwe imakhudzidwa ndi zinthu monga zinthu za batri, njira yopangira ndi mawonekedwe a batri.Imagawidwa kukhala ohmic mkati kukana ndi polarization mkati kukana.Ohmic kukana kwamkati kumapangidwa ndi kukana kukana kwa ma elekitirodi, ma electrolyte, ma diaphragms ndi magawo osiyanasiyana;polarization mkati kukana amayamba chifukwa cha electrochemical polarization ndi ndende kusiyana polarization.

Mphamvu zenizeni - mphamvu ya batri pa voliyumu kapena misa.

Kulipiritsa ndi kutulutsa mphamvu - muyeso wa mlingo wa mphamvu yamagetsi yomwe imagwiritsidwa ntchito ndi batri panthawi yolipiritsa imasinthidwa kukhala mphamvu yamankhwala yomwe batri ikhoza kusunga.

Voltage - kusiyana komwe kungakhalepo pakati pa ma elekitirodi abwino ndi oyipa a batri.

Open circuit voltage: mphamvu ya batire pamene palibe dera lakunja kapena katundu wakunja wolumikizidwa.Mphamvu yamagetsi yotseguka imakhala ndi ubale wina ndi mphamvu yotsalira ya batri, kotero mphamvu ya batri nthawi zambiri imayesedwa kuti iyerekeze mphamvu ya batri.Voltage yogwira ntchito: kusiyana komwe kungathe pakati pa ma elekitirodi abwino ndi oyipa a batri pomwe batire ikugwira ntchito, ndiye kuti, pakakhala kupitilira kwamagetsi.Kutaya mphamvu yamagetsi: mphamvu yofikira batire itatha kulipiritsa ndi kutulutsidwa (ngati kutulutsa kumapitirira, kumatulutsidwa mopitirira muyeso, zomwe zingawononge moyo ndi ntchito ya batri).Charge-cut-off voltage: mphamvu yamagetsi ikasintha nthawi zonse kuti ipitirire nthawi yolipirira.

Kuthamanga ndi kutulutsa - tulutsani batri ndi mphamvu yokhazikika ya 1H, ndiko kuti, 1C.Ngati batire ya lithiamu idavotera 2Ah, ndiye kuti 1C ya batire ndi 2A ndi 3C ndi 6A.

Kulumikizana kofanana - Kuchuluka kwa mabatire kungawonjezeke powalumikiza mofanana, ndi mphamvu = mphamvu ya batri imodzi * chiwerengero cha malumikizidwe ofanana.Mwachitsanzo, gawo la Changan 3P4S, mphamvu ya batri imodzi ndi 50Ah, ndiye mphamvu ya module = 50 * 3 = 150Ah.

Kulumikizana kwa Series - Magetsi a mabatire amatha kuonjezedwa powalumikiza motsatizana.Voltage = mphamvu ya batri imodzi * kuchuluka kwa zingwe.Mwachitsanzo, gawo la Changan 3P4S, mphamvu ya batri imodzi ndi 3.82V, ndiye voteji ya module = 3.82 * 4 = 15.28V.

Monga chigawo chofunikira mu magalimoto amagetsi, mphamvu za lithiamu batri modules zimagwira ntchito yofunika kwambiri posungira ndi kutulutsa mphamvu zamagetsi, kupereka mphamvu, ndi kuyang'anira ndi kuteteza mapaketi a batri.Iwo ali ndi zosiyana zina mu kapangidwe, ntchito, makhalidwe ndi ntchito, koma zonse zimakhudza kwambiri ntchito ndi kudalirika kwa magalimoto amagetsi.Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukulitsa kwa ntchito, ma module a lithiamu batire amphamvu apitiliza kupanga ndikupanga zopereka zazikulu pakukweza ndi kutchuka kwa magalimoto amagetsi.
