Hokwan a Wɔde Bɔ Ka Ne Mmuae a Ɛfata Koro na Ma Multi-Shift Dwumadie

Ma memfa asɛm no awiei nhyɛ da. Sɛ wo adekoradan no yɛ adwuma mprenu anaa abiɛsa a, wo werɛ mfi sɛnea wɔtaa gye sika no. Kɔ hokwan a wɔde gye sika so tẽẽ.

Nea enti a ɛte saa no yɛ tiawa: lithium batere nhaw no sɛ wɔbɛbɔ no fã bi. Wɔtan nsu a wɔtow gu kyinhyia a edi mũ ankasa. Battery University sɔhwɛ kyerɛ sɛ SOC a wɔde bɛto 20% ne 80% ntam no betumi atrɛw cycle nkwa nna mu mpɛn 2 kosi 3 (batteryuniversity.com). Lead-acid yɛ nea ɛne no bɔ abira, ehia charges a edi mũ na ama wɔakwati sulfation. Ntease soronko koraa.

Sɛnea hokwan charge yɛ adwuma wɔ nneyɛe mu: operator plugs in wɔ awia ahomegye bere mu, de 15% kɔ 20% charge ka ho wɔ simma 15 mu. Simma 20 foforo wɔ shift nsakrae mu. Mmiɛnsa anaa anan a wɔbɔ no fã bi da mũ no nyinaa, SOC tra 40% ne 85% ntam. Battery nsakrae biara nni hɔ. Batere dan biara nni hɔ a ɛho nhia.

Ɔkwan a wɔfa so de charge no gyina wo shift pattern so:

Single shift, ase nnɔnhwerew 8 da biara: amanne kwan so charging yɛ adwuma yiye. Charge anadwo, tu mmirika da mũ nyinaa. Lithium mfaso a ɛwɔ ha titiriw ne zero maintenance na backup battery biara ho nhia.

Nsakrae abien anaa adwumayɛ a wɔatrɛw mu: hokwan a wɔbɔ no yɛ gyinapɛn. Ɛsɛ sɛ wɔkyekyɛ charger ahorow wɔ adwumayɛbea hɔ. Mmeae a wobubu, mmeae a wɔsesa nsakrae, bɛn hyɛn gyinabea apon.

Amanne kwan so lead-acid dwumadie no tu mmirika 2 kɔsi 3 wɔ lɔre biara mu. Baako a wɔde redi dwuma, biako rebɔ, biako a ɛreyɛ nwini. Lithium nhia saa nneɛma no mu biara.

Tumi a Wɔpaw: Nnipa Dodow no ara Nhu Eyi Mfomso

Customer bisaa me ɔsram a etwaam no, 48V 400Ah anaa 48V 700Ah, bo nsonsonoe bɛyɛ $8,000. Na ne nkate a edi kan ne sɛ ɔbɛtɔ nneɛma nketenkete, akora sika so.

Afei wo hia 700Ah no.

Tumi ketewa kyerɛ sɛ wɔtaa charge. 400Ah battery a ɛretu mmirika abien no hia anyɛ yiye koraa no charge abien na ama atumi afa da no mu. Sɛ charger ahorow nyinaa wɔ batere dan mu a, ɛsɛ sɛ wɔn a wɔde di dwuma no san de kar no san ba pɔtee na wɔatumi abɔ.

700Ah battery a hokwan biako charge anɔpa, biako awia aduan, fa da no mu. Akwantu titiriw biara nni hɔ a wɔbɛsan akɔ batere dan no mu.

Lithium batere biara wɔ BMS (Battery Management System). Ɛsono sɛnea adwumakuw ahorow a wɔyɛ nneɛma ahorow de BMS di dwuma wɔ ɔkwan soronko so koraa.

Ɔhaw ahorow a m’ankasa mahyia:

Ɔhyew a wɔbɔ ho ban yɛ ade foforo. BMS a ɛfata bara sɛ wɔmfa charge a ɛba fam sen 0℃(32℃F) efisɛ awɔw a wɔde charge no ma lithium plating ba anode no so. Tumi a wɔhwere daa, a wontumi nsakra.
