Chiyambi:
M'mawu osavuta, kusanja ndi avareji balancing voteji. Sungani voliyumu yalithiamu batire paketimosasinthasintha. Kulinganiza kumagawika kukhala kulinganiza kogwira ntchito ndi kuwongolera mokhazikika. Ndiye pali kusiyana kotani pakati pa kulinganiza kogwira ntchito ndi kusanja kwa batri ya lithiamu? Tiyeni tiwone ndi Heltec Energy.
Kulinganiza kogwira kwa bolodi loteteza batire la lithiamu
Kulinganiza kogwira mtima ndikuti chingwe chokhala ndi voteji yapamwamba chimawonjezera mphamvu ku chingwe chokhala ndi voteji yotsika, kuti mphamvu isawonongeke, voteji yayikulu imatha kutsitsidwa, ndipo voteji yotsika imatha kuwonjezeredwa. Mtundu woterewu ukhoza kusankha kukula komwe kulipo panokha. Kwenikweni, 2A imagwiritsidwa ntchito kwambiri, ndipo palinso zazikulu zomwe zili ndi 10A kapena kupitilira apo.
Tsopano zida zogwirira ntchito zofananira pamsika zimagwiritsira ntchito mfundo ya thiransifoma, kudalira tchipisi chamtengo wapatali cha opanga chip. Kuphatikiza pa kusanja chip, palinso zida zotumphukira zokwera mtengo monga zosinthira, zomwe ndi zazikulu komanso zokwera mtengo.
Zotsatira za kugwirizanitsa zogwira ntchito ndizodziwikiratu: kugwira ntchito kwakukulu, mphamvu zochepa zimatembenuzidwa ndipo sizimatayika mwa mawonekedwe a kutentha, ndipo kutayika kokha ndi koyilo ya thiransifoma.
Kusanja kwamakono kungasankhidwe ndipo liwiro la kugwirizanitsa liri mofulumira. Kulinganiza mwachidwi kumakhala kovuta kwambiri pamapangidwe kuposa kusanja mokhazikika, makamaka njira ya transformer. Mtengo wa BMS wokhala ndi ntchito yofananira udzakhala wokwera kwambiri kuposa wongoyerekeza, womwe umalepheretsanso kupititsa patsogolo kulinganiza mwachangu.BMS.
Kusanjikiza pang'ono kwa bolodi loteteza batire la lithiamu
Passive balancing imachitika powonjezera resistors kuti atuluke. Chingwe chokwera kwambiri cha maselo chimatulutsidwa mwa mawonekedwe a kutentha kwa kutentha kumalo ozungulira, kukwaniritsa zotsatira za kuziziritsa kotsutsa. Choyipa chake ndikuti kutulutsa kumatengera chingwe chotsika kwambiri chamagetsi, ndipo pali kuthekera kwachiwopsezo pakulipira.
Kusamalitsa kosalekeza kumagwiritsidwa ntchito makamaka chifukwa cha mtengo wake wotsika komanso mfundo yosavuta yogwirira ntchito; kuipa kwake ndi koyenera kutengera mphamvu yotsika kwambiri, ndipo sangathe kuwonjezera chingwe chochepa chamagetsi, zomwe zimapangitsa kuti mphamvu ziwonongeke.
Kusiyana pakati pa kusanja mogwira ntchito ndi kusanja mokhazikika
Passive balancing ndi yoyenera kwa mphamvu yaying'ono, yotsika-voltagemabatire a lithiamu, pamene kugwirizanitsa yogwira ndi koyenera kwa high-voltage, mphamvu yaikulu ya lithiamu batire paketi ntchito.
Ukadaulo wokhazikika womwe umagwiritsidwa ntchito nthawi zambiri umaphatikizapo kuthamangitsa shunt resistor kulinganiza, kuthamangitsa shunt resistor kusanja, pafupifupi batire voteji kusanja kulipiritsa, switch capacitor kusanja kulipiritsa, buck converter kusinthanitsa kulipiritsa, inductor kugwirizanitsa kulipiritsa, ndi zina zambiri. mndandanda, batire iliyonse iyenera kulipiritsidwa mofanana, apo ayi ntchito ndi moyo gulu lonse la batri lidzakhudzidwa panthawi yogwiritsira ntchito.
| Mawonekedwe | Kusalongosoka | Kulinganiza mwachangu |
| Mfundo yogwira ntchito | Gwiritsani ntchito mphamvu zambiri kudzera pa resistors | Sanjani mphamvu ya batri kudzera mu kutumiza mphamvu |
| Kutayika kwamphamvu Kwambiri | mphamvu kuonongeka ngati kutentha Small | kutengerapo koyenera kwa mphamvu zamagetsi |
| Mtengo | Zochepa | Wapamwamba |
| Kuvuta | Tekinoloje yotsika, yokhwima | Mapangidwe apamwamba, ovuta amafunikira |
| Kuchita bwino | Kutsika, kutaya kutentha | Pamwamba, pafupifupi palibe kutaya mphamvu |
| Zotheka | zochitika Ma batire ang'onoang'ono kapena mapulogalamu otsika mtengo | Ma batire akuluakulu kapena mapulogalamu ochita bwino kwambiri |
Mfundo yofunikira ya kusanja mokhazikika ndikukwaniritsa kulinganiza mwa kuwononga mphamvu zochulukirapo. Nthawi zambiri, mphamvu yochulukirapo mu paketi ya batire ya overvoltage imasinthidwa kukhala kutentha kudzera pa resistor, kotero kuti voteji ya batri imakhalabe yosasinthasintha. Ubwino wake ndikuti dera losanja losasunthika ndi losavuta komanso mtengo wopangira ndi kukhazikitsa ndi wotsika. Ndipo ukadaulo wongoyerekeza ndi wokhwima kwambiri ndipo wakhala ukugwiritsidwa ntchito kwambiri pamitengo yotsika komanso yaying'onomapaketi a batri.
Choyipa ndichakuti pali kutayika kwakukulu kwa mphamvu chifukwa cha kutembenuka kwa mphamvu yamagetsi kukhala kutentha kudzera kukana. Kuchita bwino pang'ono, makamaka m'mapaketi a batri amphamvu, kuwononga mphamvu kumawonekera kwambiri, ndipo sikuli koyenera kugwiritsa ntchito batire yayikulu, yogwira ntchito kwambiri. Ndipo chifukwa mphamvu yamagetsi imasinthidwa kukhala kutentha, imatha kupangitsa kuti batire litenthe kwambiri, zomwe zimakhudza chitetezo ndi moyo wadongosolo lonse.
Kusamutsa magetsi kumatheka posamutsa mphamvu yamagetsi yochulukirapo kuchoka ku mabatire okhala ndi mphamvu zambiri kupita ku mabatire okhala ndi mphamvu zochepa. Njirayi nthawi zambiri imasintha kagawidwe ka magetsi pakati pa mabatire kudzera pakusintha magetsi, zosinthira za buck-boost kapena zida zina zamagetsi. Ubwino wake ndi wokwera kwambiri: mphamvu sizimawonongeka, koma zimayenderana ndi kusamutsa, kotero kulibe kutaya kwa kutentha, ndipo mphamvuyo nthawi zambiri imakhala yapamwamba (mpaka 95% kapena kuposa).
Kupulumutsa mphamvu: Popeza kulibe mphamvu zowononga mphamvu, ndizoyenera kuchita zazikulu, zogwira ntchito kwambirilithiamu batiremachitidwe ndipo amatha kuwonjezera moyo wautumiki wa paketi ya batri. Zogwiritsidwa ntchito pamapaketi akuluakulu a batri: Kulinganiza kogwira kumakhala koyenera kwa mapaketi a batri akulu akulu, makamaka pamiyeso monga magalimoto amagetsi ndi makina osungira mphamvu, ndipo kumatha kupititsa patsogolo magwiridwe antchito ndi kupirira kwadongosolo.
Choyipa chake ndikuti kupanga ndi kukhazikitsa kulinganiza kogwira ntchito kumakhala kovuta, nthawi zambiri kumafunikira zida zambiri zamagetsi, kotero mtengo wake ndi wapamwamba. Kuvuta kwaukadaulo: Kuwongolera mwatsatanetsatane ndi kapangidwe ka dera ndikofunikira, zomwe ndizovuta ndipo zitha kukulitsa zovuta zachitukuko ndi kukonza.
Mapeto
Ngati ndi yotsika mtengo, kachitidwe kakang'ono kapena ntchito yokhala ndi zofunikira zochepa zofananira, kusanja mokhazikika kungasankhidwe; kwa machitidwe a batri omwe amafunikira kuwongolera mphamvu moyenera, mphamvu yayikulu kapena magwiridwe antchito apamwamba, kulinganiza mwachangu ndi chisankho chabwinoko.
Heltec Energy ndi kampani yomwe imapanga ndi kupanga zida zoyesera ndi kukonza batri yapamwamba kwambiri, ndipo imapereka mayankho opangira kumbuyo, kupanga mapaketi, ndi kukonza mabatire akale.mabatire a lithiamu.
Heltec Energy wakhala anaumirira pa luso lodziimira yekha, ndi cholinga chachikulu cha kupereka odalirika ndi okwera mtengo kwambiri mankhwala mu lifiyamu batire makampani, ndi ndi lingaliro utumiki "makasitomala woyamba, khalidwe kupambana" kulenga mtengo kwa makasitomala. Pachitukuko chake, kampaniyo ili ndi gulu la akatswiri apamwamba pamakampani, omwe amatsimikizira kuti zinthu zikuyenda bwino komanso zothandiza.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, musazengereze kuterokufikira kwa ife.
