Kedu ka esi etinye nchekwa ike nke ụgbọ ala igwe mkpanaka

The ike nchekwa nke ụgbọ ala ike mkpanakana-tumadi ghọtara site na batrị. Batrị bụ ngwaọrụ na-agbanwe ike kemịkalụ ka ọ bụrụ ike eletrik, nke kachasị na ya bụ batrị lithium-ion.

Batrị lithium-ion a na-eji n'ụgbọ ala ike mkpanaka na-enwekarị ọtụtụ sel. A na-ejikọta cell ọ bụla site na onye nkewa nke ejiri ihe dị mma na nke na-adịghị mma. Ihe cathode na-ejikarị oxides, dị ka lithium cobalt oxide, lithium manganate, wdg, na ihe electrode na-adịghị mma na-ejikarị graphite eme ihe.

Usoro nchekwa ike nke batrị lithium-ion nwere ike kewaa n'ụzọ abụọ: chaja na ịchaji. Mgbe ị na-akwụ ụgwọ, isi iyi na-agafe ọkụ eletrik site na electrode dị mma nke batrị ahụ, na-eme ka ion lithium na-agbanye n'etiti electrodes dị mma na nke na-adịghị mma. N'oge a, ion lithium na-apụ na electrode dị mma, na-ebuga na electrode na-adịghị mma site na ions dị na electrolyte, ma tinye ya na graphite nke ihe electrode na-adịghị mma. N'otu oge ahụ, ion dị mma na electrolyte na batrị na-akwagakwa ịnọgide na-anọpụ iche eletrik n'etiti electrodes.

Mgbe achọrọ ike eletrik echekwara, nke ugbu a na-abanye na ngwaọrụ ahụ site na electrode na-adịghị mma, na ion lithium na-aga n'ụzọ ọzọ site na electrode na-adịghị mma n'ime electrolyte n'etiti electrodes dị mma wee laghachi na ihe electrode dị mma. N'oge usoro a, mmegharị nke ion lithium na-eme ka ọkụ eletrik na-agbapụta ma na-ahapụ ike eletrik echekwara.

Nchekwa batrị nke ụgbọ ala ike mkpanaaka kwesịkwara ịtụle ụfọdụ ihe ngosi, dị ka ike batrị na voltaji. Ike na-ezo aka na ọkụ eletrik nke batrị lithium-ion nwere ike ịchekwa ma hapụ ya, a na-atụkarị ya na awa ampere (Ah). Voltaji bụ ihe dị iche na ike eletriki batrị lithium-ion. N'ozuzu, a na-eji voltaji DC, dị ka 3.7V, 7.4V, wdg.

N'ime ụgbọ ala ike mkpanaka, iji nweta nchekwa nchekwa ike dị mma, a na-achọkwa nkwado nke sistemụ njikwa batrị (BMS). BMS bụ ngwaọrụ na-ahụ maka nlekota na ijikwa batrị batrị, nke nwere ike hụ na nchekwa batrị, gbasaa ndụ ya ma melite arụmọrụ ike.

BMS na-agụnyekarị ihe mmetụta okpomọkụ, ihe mmetụta dị ugbu a, ihe mmetụta voltaji na ibe njikwa. A na-eji ihe mmetụta okpomọkụ na-enyocha ọnọdụ okpomọkụ nke ngwugwu batrị iji zere ikpo ọkụ ma ọ bụ oyi; a na-eji ihe mmetụta dị ugbu a chọpụta ụgwọ na nkwụsị nke batrị batrị iji hụ na ugbu a dị n'ime ebe nchekwa; a na-eji ihe mmetụta voltaji na-enyocha voltaji nke ngwugwu batrị iji hụ na ọ naghị ebufe ya ma ọ bụ mebie ya. Ihe mgbawa njikwa bụ maka ịnakọta data sensọ na ijikwa na jikwaa batrị site na algọridim.

Na mgbakwunye, iji melite arụmọrụ nchekwa ike nke batrị lithium-ion, a chọkwara njikwa kacha mma nke chaja batrị na mwepu. Dịka ọmụmaatụ, enwere ike iji chaja cha cha na chaja mgbe niile n'oge ị na-ebufe ya, enwere ike gbanwee mwepu nke ugbu a na voltaji dịka mkpa dị n'oge a na-ebugharị. Site n'iji ezi uche na-achịkwa usoro chajị na mwepụ, enwere ike ịbawanye nrụpụta ike nke batrị na ndụ ọrụ batrị nwere ike ịgbatị.

N'ikwu okwu n'ozuzu, a na-enweta nchekwa ike nke ụgbọ ala eletrik site na batrị lithium-ion. Batrị ndị a na-echekwa ike eletrik wee hapụ ya mgbe achọrọ ya. Site na nkwado nke usoro njikwa batrị, nchekwa na arụmọrụ nke batrị nwere ike ijide n'aka. N'otu oge ahụ, site n'ịkwalite ụgwọ na njikwa nkwụsị, enwere ike imeziwanye nchekwa nchekwa ike ma nwee ike ịgbatị ndụ batrị. Mmepe na-aga n'ihu na mmepụta nke teknụzụ nchekwa ike ga-akwalite mmepe na ngwa nke mkpanaka
