N’chifukwa chiyani batire ya lithiamu-ion yokhala ndi mphamvu yocheperako ya 100Ah nthawi zina imapereka mphamvu yeniyeni ya 70Ah yokha panthawi yogwira ntchito? Chifukwa chachikulu cha kusowa kwa mphamvu imeneyi nthawi zambiri sichimakhala kulephera kwakukulu kwa kapangidwe kake; m’malo mwake, nthawi zambiri kumachitika chifukwa cha kusalingana kwa mphamvu yamkati mwa maselo. Monga momwe chipika chachifupi kwambiri mu mbiya yamatabwa chimalamulira kuchuluka kwa madzi komwe chingathe kusunga, selo lofooka kwambiri mu dongosolo la mndandanda limatsimikizira mphamvu yogwiritsidwa ntchito ya batire yonse. Pamene kusiyana kwa mphamvu yamagetsi pakati pa maselo kupitirira 30mV, njira zokhazikika zolumikizirana zomwe zimaphatikizidwa mu Standard Battery Management Systems (BMS) sizitha kukonza kusiyanaku. Pansi pa mikhalidwe iyi, batire yapadera yolinganiza imakhala chida chabwino kwambiri chokonzera kusalingana kwa maselo a batire. Kuti athetse vuto lenileni la ntchito,Chengdu Heltec Energy Technology Co., Ltd.imapereka ukadaulo wapamwamba wolinganiza bwino komanso zida zokonzera zomwe zimapangidwira kuti ziwongolere ndikukonza maselo omwe ali pamavuto, kutsegula mphamvu zochepa, ndikubwezeretsa batire pamlingo wake wogwirira ntchito.
Zolepheretsa Kugwira Ntchito za Kulinganiza Zinthu Pantchito Yosamalira ndi Kukonza
Machitidwe okhazikika olinganiza zinthu (standard passive balancing systems) amagwira ntchito potulutsa mphamvu yochulukirapo kuchokera ku maselo amphamvu kwambiri ngati kutentha kudzera mu ma resistors a shunt. Ngakhale kuti kapangidwe kameneka ndi kokwanira kusunga maselo athanzi komanso ofanana bwino panthawi yogwira ntchito, sikukwanira pamene kusiyana kwa magetsi kumapitirira 50mV kapena pamene maselo akale amasakanizidwa ndi atsopano panthawi yomanganso pang'ono kwa paketi. Kulinganiza zinthu mosasinthasintha kumagwira ntchito pamagetsi otsika kwambiri, nthawi zambiri pakati pa 30mA ndi 100mA, zomwe zikutanthauza kuti kuthetsa kusiyana kwakukulu kwa mphamvu m'mapaketi amphamvu kwambiri kungatenge masiku, ngati si milungu ingapo.
Pofuna kuthana ndi kusalingana kwakukulu kumeneku, malo osamalira akatswiri amagwiritsa ntchito zida zapadera zosamalira m'malo modalira zida wamba zamkati. Chengdu Heltec Energy Technology Co., Ltd. imathetsa vutoli mwa kupanga zinthu zolemera.choyezera batrizida zomwe zimaphatikiza kuyeza molondola kwa magetsi, kuzindikira kukana kwamkati, ndi kusamutsa mphamvu yamagetsi amphamvu. M'malo mongowononga mphamvu ngati kutentha, ma equalizer okonza awa amachotsa mphamvu kuchokera ku maselo amphamvu kwambiri ndikugawanso mwachindunji ku maselo amphamvu kwambiri, kukonza kusiyana kwakukulu kwa maselo mkati mwa nthawi yeniyeni yogwirira ntchito.
Mafotokozedwe Aukadaulo ndi Kapangidwe ka Uinjiniya
Kulondola kwa zida zapadera zokonzera kumadalira mwachindunji kapangidwe ka zowongolera ndi kutsimikiza kwa muyeso wa dongosololi. Heltec Energy imapanga zida zake zowunikira ndi kukonza pogwiritsa ntchito ma microcontroller units (MCUs) othamanga kwambiri ochokera ku Microchip Technology Inc. Ma processor awa amathandizira kuzindikira magetsi nthawi yeniyeni m'maselo aliwonse okhala ndi miyeso ya 1V mpaka 5V pa selo iliyonse komanso kulondola kwa ±1mV. Dongosolo lowongolera lamkati limazindikira zokha makonzedwe a mabatire olumikizidwa, kuthandizira makonzedwe kuyambira 2S mpaka 24S, ndi mitundu yapadera yotsogola yomwe imakulitsa mphamvu mpaka 32S. Kapangidwe ka multichemistry aka kamalola chida chimodzi kugwira ntchito ndi mankhwala a Lithium Nickel Manganese Cobalt Oxide (NCM), Lithium Iron Phosphate (LFP), ndi Lithium Titanate (LTO) popanda kufunikira kukonzanso kwa kapangidwe kake.
Ntchito yaikulu yochiritsira ya chipangizochi imadalira njira yolumikizira mphamvu ndi kusamutsa mphamvu yomwe imapereka mphamvu yolinganiza mpaka 15A kapena 25A kutengera kapangidwe ka mtundu winawake. Mosiyana ndi ma board oyambira a active balance omwe mphamvu yotulutsa imatsika pamene ma voltage a cell akukumana, zida za Heltec Energy zimasunga kusamutsa kokhazikika, kwamphamvu komwe kumagwira ntchito mosadalira kusiyana kwa magetsi. Akatswiri amatha kusankha kuchokera ku njira zitatu zogwirira ntchito kudzera pa interface: equalization yamanja, equalization yodziyimira payokha, kapena equalization yothandizidwa ndi charge. Kapangidwe kake kamaphatikizapo gulu lowongolera lovomerezeka lomwe limasintha pakati pa madigiri 0 ndi 45 kuti ligwirizane ndi malo ogwirira ntchito oyimirira kapena okhala, mawonekedwe olumikizira amtundu wa mainchesi 7, ndi batani loyimitsa mwadzidzidzi.
Kuti chitetezo chikhale chotetezeka panthawi yotumiza mphamvu yamagetsi yamphamvu kwambiri, ma circuitry amaphatikizapo chitetezo chamagetsi a selo limodzi pamodzi ndi machenjezo a hardware nthawi yeniyeni okhudza polarity yobwerera m'mbuyo, kuchuluka kwa magetsi a pack, mikhalidwe yosakhala ndi magetsi, ndi kutentha kwa transistor yamkati ya metal-oxide-semiconductor field-effect transistor (MOSFET). Ma configurations apamwamba, monga chitsanzo cha HT-CJ32S25A, amaphatikizanso ma onboard liquid-crystal displays (LCD) kuti awonetse ma voltages amtundu uliwonse, cumulative pack voltage, active balancing current, ndi kutentha kwamkati pamodzi ndi kulumikizana kwa pulogalamu ya Wi-Fi yolumikizidwa kuti ilowetse deta yakutali.
Zochitika Zogwiritsira Ntchito Pakukonzanso ndi Kukonza Mabatire Amakono
Kugwiritsidwa ntchito kwa zida zokonzera zamagetsi zamagetsi kumagawidwa m'magulu atatu osiyanasiyana amsika, iliyonse ikuwonetsa mapangidwe apadera a paketi ndi zofunikira pakugwira ntchito:
1. Kuyenda Mosavuta ndi Mayendedwe Aumwini
Magalimoto amagetsi opepuka, monga ma scooter amagetsi, magalimoto oyenda okha, ndi ngolo za gofu, nthawi zambiri amagwiritsa ntchito mabatire ochepa komanso okhuthala. Magalimoto awa akamawonongeka, zoyesa mphamvu zonyamulika ndi zoyezera zamagetsi zimayikidwa pamalopo. Chidachi chimayang'ana ma module ang'onoang'ono, ndikulekanitsa maselo olimbana kwambiri ndikuyendetsa phukusi mkati mwa malo okonzera popanda kufunikira kutumiza phukusi lonse ku malo ogwirira ntchito.
2. Magalimoto a Magalimoto Amalonda ndi Magalimoto Oyendera Anthu
Ogwira ntchito m'magalimoto, ntchito zogawana magalimoto, ndi malo ogwirira ntchito okonza magalimoto amachita ndi ma module a batri amphamvu kwambiri komanso amphamvu. Pa ntchito izi, oyesa ma benchtop charge/discharge amaphatikizidwa ndi ma module active balancing systems. Akatswiri amagwiritsa ntchito njira zonse zotsimikizira mphamvu, pogwiritsa ntchito njira zowunikira mozama kuti akonze kusiyana kwa maselo ndi maselo komwe kumachitika chifukwa cha kutentha kosafanana komwe kumapezeka m'magalimoto apansi pa galimoto.
3. Magetsi a Mafakitale ndi Malo Osungira Mphamvu a Gridi
Malo osungira mphamvu m'nyumba, malo olumikizirana mauthenga, ndi malo opangira mphamvu ya dzuwa amadalira mabatire akuluakulu, okhala ndi njira zambiri. Kusalingana kwa malo okhazikitsa awa kungachepetse phindu la ndalama zomwe zayikidwa pamakina obwezeretsanso mphamvu. Makina okonzera njira zambiri amagwiritsidwa ntchito poyendetsa ma cell ndikuwongolera mphamvu zamagetsi m'magawo akuluakulu, kubwezeretsa kukhazikika kwa makina ndikukhazikitsa zomangamanga zamagetsi zosungira mafakitale.
Kukonza Magwiridwe Antchito ndi Kukulitsa Moyo
Mwa kuphatikiza mayeso ozindikira matenda ndi kugawanso mphamvu yogwira ntchito, zida zapadera zolinganiza zimasintha momwe thanzi la batri limayendetsedwera m'ma workshop aukadaulo. Kukonza kukhazikika kwa ma voteji a maselo mpaka ku 1mV kumalola mwachindunji maselo aliwonse kufika pamlingo wawo wotsika kapena wapamwamba wa voltage isanakwane. Kukonza kulinganiza kumeneku kumathandiza opereka chithandizo, kukonza maukonde a zomangamanga, ndi malo opangira zinthu kuti abwezeretse mphamvu yotayika ya paketi, kuchepetsa ndalama zonse zomwe zimagwiritsidwa ntchito pa chitsimikizo, ndikuwonetsetsa kuti makina osungira mphamvu akukhazikika. Kusankha kukhazikika koyenera kutengera ma chemistry a maselo ndi makonzedwe angapo kumalola ogwiritsa ntchito kusunga zinthu za hardware ndikuwonjezera nthawi yogwira ntchito ya ma paketi a batri a lithiamu a mafakitale.
Kuti mufufuze zofunikira zaukadaulo, fufuzani kabukhu konse ka zida, kapena funsani mafunso aukadaulo, pitani patsamba lovomerezeka la kampani pahttps://www.heltec-energy.com/.
