Ibhetri yeLiFePO4 engena-BMS yimbopheleleko engenamkhethe.
Isiganeko esinye sokutshaja kakhulu sinokutshabalalisa iiseli ngokusisigxina. I-BMS engalunganga
kubangela iinyanga zokunqunyulwa kwezinto ezingaqhelekanga kunye nokuchithwa kwamandla. Esi sikhokelo
igubungela yonke into oyifunayo ukuze wenze isigqibo esifanelekileyo.
I-BMS yenza imisebenzi emithathu ngaxeshanye:
Ukhuselekoinqumla isekethe xa nayiphi na iseli idlula ifestile yayo ekhuselekileyo — itshaja engaphezulu kwe-3.65 V/iseli, ikhuphe ngaphantsi kwe-2.8 V/iseli (umda osebenzayo ocetyiswayo), okanye xa imeko yangoku, yobushushu, okanye yesekethe emfutshane iba yingozi.
Ukulinganiselailungisa ukushukuma kwendalo phakathi kweeseli nganye kwiinkulungwane zemijikelo. Ngaphandle kwayo, eyona seli yakho ibuthathaka ichaza amandla okusetyenziswa kwephakheji yakho yonke - kwaye iyancipha ngokukhawuleza.
Ukubeka ilisoIlandelela imeko yetshaja (i-SOC), imeko yempilo (i-SOH), i-voltage ngeseli nganye, ubushushu, kunye nokubalwa komjikelo ngexesha langempela. Le datha ikuvumela ukubamba iseli engasebenziyo ngaphambi kokuba iwise iphakheji.
I-LiFePO4's flat discharge curve ifuna i-BMS ethile yekhemistri. I-BMS eqhelekileyo iya kuyifunda gwenxa i-SOC kulo lonke ithafa kwaye ibangele ukunqunyulwa kwe-low-voltage okungeyonyani okushiyekileyo kunye namandla amaninzi.
Indlela Yokulinganisa I-BMS Yakho
Iinkcukacha ezimbini mazihambelane ngokuchanekileyo nepakethi yakho.
Inyathelo 1 — I-Voltage (uluhlu lweeseli).Iphakheji ye-4S ifuna i-4S BMS. Iphakheji ye-16S ifuna i-16S BMS. Ukucima kweseli enye kubangela ukufundwa kakubi kwe-voltage kunye nokukhuselwa okungathembekanga.
| Uqwalaselo | I-Voltage Eqhelekileyo | I-Voltage yokutshaja ephezulu | Isicelo esiqhelekileyo |
|---|---|---|---|
| 4S | 12.8 V | 14.6 V | I-RV, i-marine, ngaphandle kwegridi |
| 8S | 25.6 V | 29.2 V | Iimoto zokutrola, i-24V yelanga |
| 16S | 51.2 V | 58.4 V | Indawo yokugcina izinto ekhaya, inqwelo yegalufa |
| 24S | 76.8 V | 87.6 V | I-72V EV, yemizi-mveliso |
Inyathelo lesi-2 — Okwangoku.Yahlula umthwalo wakho ongapheliyo ophezulu kwiiwatts ngevolthi yepakethi, uze wongeze umda wokhuseleko ongama-25–30%.
5,000 W ÷ 48 V = 104 A → Khetha i-150 A BMSUngaze usebenzise i-BMS kwi-100% yamandla ayo asemgangathweni. Ukunciphisa ubushushu kunye nemithwalo yokugquma kusoloko kutyhala imfuno yehlabathi lokwenyani ngaphezu kwenani elibaliweyo.
Ukulinganisela okusebenzayo kunye nokungashukumiyo
Ukulinganisela okungasebenziyoIchitha itshaja engaphezulu njengobushushu nge-resistor (50–200 mA). Igcina iipakethe ezihambelana kakuhle kodwa ayinakubuyisela ukushukuma okubalulekileyo kweeseli — ukulungisa ukungalingani kwe-500 mAh kuthatha malunga neeyure ezi-5 kwi-100 mA.
Ukulinganisela okusebenzayoIdlulisela amandla phakathi kweeseli ngesekethe ye-inductor-capacitor (1–5 A, ukusebenza kakuhle kwe-80–95%). Ilungisa ukungalingani nge-10–50× ngokukhawuleza kwaye isebenza kuyo yonke i-charge epheleleyo kunye ne-discharge cycle, kungekuphela nje phezulu.
| Imeko | Ingasebenzi | Iyasebenza |
|---|---|---|
| Iiseli zeqela elifanayo, ≤ 0.3C ukujikeleza | Kwanele | Uphuculo oluphantsi |
| Iphakheji ≥ 200 Ah, ukukhwela ibhayisekile yonke imihla | Imizabalazo | Icetyisiwe |
| Izinga lokukhupha igesi > 0.5C liyaqhubeka | Ayikwazi ukulandelela | Kufuneka |
| Iiseli ezixutyiweyo okanye ezindala | Ayikwazi ukubuyela kwimeko yesiqhelo | Ndingayibuyisa kwakhona ipakethi |
Khetha i-passivekwiiseli zebatch efanayo ezijikeleziswe kwi-≤ 0.3C.
Khetha esebenzayokwiipakethi ≥ 200 Ah, amazinga okukhupha amanzi angaphezu kwe-0.5C, okanye iiseli ezivela kwiibhetshi ezixutyiweyo.
Uluhlu Lokujonga Ukukhetha Olune Iinguqu Ezine
Ngaphambi kokuba u-odole, qinisekisa zonke iinguqu ezine ngaxeshanye:
| Iyaguquguquka | Imfuneko |
|---|---|
| Ubalo lwechungechunge | Ihambelana ngqo noqwalaselo lweseli yakho |
| Umbane oqhubekayo | Umthwalo ophezulu (W) ÷ i-voltage (V) + umda we-25–30% |
| Iimbonakalo | I-Bluetooth (yonke) · I-RS485/I-CAN (yelanga) · Ukulinganisela okusebenzayo (≥ 200 Ah) |
| Ikhemistri | Qinisekisa uqwalaselo lomgca we-LFP/LiFePO4 |
Iiyunithi ze-DALY Energy BMS zigubungela i-4S ukuya kwi-24S kunye ne-10 A ukuya kwi-500 A, kwi-standard, smart (Bluetooth + RS485/CAN), kunye ne-active balance configurations — zonke zithunyelwa nge-LFP chemistry thresholds ngokuzenzekelayo.
