I. Okwu mmalite
NkeDL-R10Q-F8S24V150Angwaahịa bụ bọọdụ nchebe sọftụwia emebere maka ngwugwu batrị mmalite ụgbọ ala. Ọ na-akwado iji usoro 8 nke 24V lithium iron phosphate batrị batrị ma na-eji atụmatụ N-MOS na otu pịa mmanye mmalite ọrụ.
Usoro niile na-anabata AFE (mgbawa nnweta n'ihu) na MCU, yana enwere ike gbanwee ụfọdụ paramita site na kọmpụta dị elu dị ka mkpa ndị ahịa si dị..
II. Nchịkọta ngwaahịa na atụmatụ
1. Igwe ọkụ ahụ na-eji mkpụrụ aluminom nwere nhazi na usoro wiring dị ugbu a, nke nwere ike iguzogide nnukwu mmetụta dị ugbu a.
2. Ọdịiche ahụ na-anabata usoro mkpuchi ịkpụzi injection iji melite nguzogide mmiri, gbochie oxidation nke akụrụngwa, yana ịgbatị ndụ ọrụ ngwaahịa ahụ..
3. ihe mkpuchi uzuzu, ihe na-awụ akpata oyi n'ahụ, mgbochi mgbochi na ọrụ nchebe ndị ọzọ.
4. Enwere ụgwọ nfe zuru oke, nfefe n'elu, n'elu-ugbu a, obere sekit, ọrụ nhazi nha..
5. Ihe eji eme ihe na-ejikọta nnweta, njikwa, nkwurịta okwu na ọrụ ndị ọzọ n'ime otu.
III. Nkọwa nzikọrịta ozi
1. UART nkwurịta okwu
Igwe a na-adaba na nzikọrịta UART na ọnụego baud nke 9600bps. Mgbe nkwurịta okwu nkịtị gasịrị, enwere ike ịlele data mkpọ batrị site na kọmpụta dị elu, gụnyere voltaji batrị, ugbu a, okpomọkụ, SOC, ọnọdụ BMS, oge okirikiri, ndekọ akụkọ ihe mere eme, na ozi mmepụta batrị. Enwere ike ịrụ ntọala ntọala na njikwa njikwa kwekọrọ, yana akwadokwa ọrụ nkwalite mmemme.
2. Nwere ike nkwukọrịta
Igwe a na-akwado nhazi nzikọrịta ozi CAN, yana ọnụego baud ndabara nke 250Kbps. Mgbe nkwurịta okwu nkịtị gasịrị, enwere ike ịlele ozi dị iche iche nke batrị na kọmpụta dị elu, gụnyere voltaji batrị, ugbu a, okpomọkụ, ọkwa, SOC, na ozi mmepụta batrị. Enwere ike ịme ntọala ntọala na njikwa njikwa kwekọrọ, yana akwadokwa ọrụ nkwalite mmemme. Usoro ndabara bụ lithium CAN protocol, na akwadokwa ịhazi nhazi protocol.
IV. Akụkụ akụkụ nke BMS
Nha BMS: Ogologo * Obosara * Elu (mm) 140x80x21.7
V. Nkọwa ọrụ igodo
Bọtịnụ edemede: Mgbe bọọdụ nchebe nọ na ọnọdụ ihi ụra dị obere, pịa bọtịnụ nkenke maka 1s ± 0.5s iji teta bọọdụ nchekwa;
Igodo mmanye mmalite: Mgbe batrị nọ n'okpuru voltaji ma ọ bụ mmejọ ndị ọzọ metụtara mwepu na-eme, BMS ga-agbanyụ ọkụ MOS tube, na n'oge a, ụgbọ ala enweghị ike ịmalite mgbanye. Site na ịpị ma jide igodo maka 3S ± 1S, BMS ga-emechi MOS n'ike n'ike maka 60S ± 10S iji gboo mkpa ike n'okpuru ọnọdụ pụrụ iche;
Nleba anya: Ọ bụrụ na a na-agbanye mmalite mmalite mmanye, MOS na-amanye nso ọrụ ga-ada, ma ọ dị mkpa nyochaa ma enwere sekit dị mkpụmkpụ na mpụga ngwugwu batrị.
VI. Ntuziaka wiring
1. Mbụ, jikọọ bọọdụ nchebe B- ahịrị na electrode na-adịghị mma nke mkpọ batrị;
2. The collection cable na-amalite site na mbụ nwa waya ejikọta B-, nke abụọ waya na-ejikọta mma okporo osisi nke mbụ eriri batrị, wee sequentially jikọọ nti osisi nke ọ bụla eriri nke batrị; Tinye eriri n'ime osisi nchebe ọzọ;
3. Mgbe emechara akara ahụ, tụọ ma batrị B +, B- voltaji na P +, ụkpụrụ P- voltaji bụ otu, na-egosi na bọọdụ nchebe na-arụ ọrụ nke ọma; Ma ọ bụghị ya, biko soro ntuziaka ndị a ọzọ;
4. Mgbe ị na-akwasa bọọdụ nchebe, buru ụzọ wepụ eriri ahụ (ọ bụrụ na enwere eriri abụọ, bupụ eriri voltaji dị elu na mbụ na eriri obere voltaji), wee wepụ eriri ọkụ B-.
VII. Mkpachapụ anya
1. Enweghị ike ịgwakọta BMS nke nyiwe voltaji dị iche iche. Dịka ọmụmaatụ, enweghị ike iji NMC BMS na batrị LFP.
2. Igwe eriri nke ndị na-emepụta ihe dị iche iche abụghị ihe zuru ụwa ọnụ, biko jide n'aka na ị na-eji eriri ndị na-ejikọta ụlọ ọrụ anyị.
3. Mee ihe iji wepụ ọkụ eletrik mgbe ị na-anwale, wụnye, na-emetụ aka na iji BMS.
4. Ekwela ka okpomọkụ dissipation elu nke BMS kpọtụrụ cell batrị ozugbo, ma ọ bụghị okpomọkụ ga-adị.bufee na sel batrị ma metuta nchekwa batrị.
5. Achịkọtala ma ọ bụ gbanwee akụkụ BMS n'onwe gị
6. Ụlọ ọrụ nchebe efere metal okpomọkụ sink e anodized na mkpuchi. Mgbe oyi akwa oxide mebiri emebi, ọ ka ga-eduzi ọkụ eletrik. Zere kọntaktị n'etiti igwe ọkụ na isi batrị na nickel strip mgbe a na-arụ ọrụ mgbakọ.
7. Ọ bụrụ na BMS adịghị mma, biko kwụsị iji ya ma jiri ya mee ihe mgbe edozichara nsogbu ahụ.
8. Ejila BMS abụọ n'usoro ma ọ bụ ihe yiri ya.
