Galoi mung san ai ga san ni
San: Forklift langai a battery gaw, shadawn shadang hku nna kade daram na hkra lang lu ai kun?
A: Lead-acid forklift battery ni gaw 1,000–1,500 lang charge galaw lu ai, dai gaw shift langai lang hta 3–5 ning daram hkam sharang lu ai. LiFePO4 lithium battery ni gaw, bungli galaw ai masa hta hkan nna, 3,000–6,000+ cycle hpe jaw ya lu nna, bungli galaw ai masa hta hkan nna 8–15 ning tup hkam sharang lu ai.
San: Forklift battery langai hpe charge galaw ai shaloi hkying hkum kade lang lang ai kun?
A: Hkum tsup ai LFP forklift battery gaw hkying hkum 6-8 tup matut manoi bungli galaw lu ai. Teng sha galaw ai aten gaw, load weight, drive cycle n-gun, grup yin nbung katsi ai hte maren shai hkat nga ai. Lead-acid battery ni gaw shawng nnan na runtime hte bung ai hpe jaw ya ai raitim, 50% SOC a lawu de n-gun jat wa ai hpe sum mat wa ai, LFP gaw discharge curve law malawng hku nna n-gun n-htum ai voltage pru ai lam hpe matut manoi tawn da ya ai.
San: Ahkaw ahkang charge galaw ai gaw forklift battery a prat hpe shayawm ya ai kun?
A: Lead-acid a matu gaw, rai na re. Cycle prat hpe 10–20% shayawm ya lu ai. LFP lithium battery ni a matu, ahkaw ahkang charge galaw ai gaw n kaja ai akyu n law htum nga ai rai nna, cycle langai hta n-gun dat dat ai lam a shadawn shadang hpe shayawm kau ai hku nna, total cycle count hpe teng sha jat ya lu ai.
San: Forklift battery a prat hpe hkra machyi shangun ai lam kaba gaw hpa rai ta?
A: Discharge a sung ai lam gaw langai sha kaba dik ai hkra machyi lam nga ai. DOD hpe 100% kaw nna 80% de shayawm ai gaw LFP chemistry a matu cycle prat hpe lahkawng lang daram jat ya lu ai. Hpang na ahkyak dik ai lam ni gaw nbung katsi ai hte charge rate rai nga ai. Hpaga lam madang hta cell ni a n bung ai lam gaw ahkyak ai raitim, law law lang n yu n hkan galaw ai lam rai nga ai.
San: Forklift a battery hpe galoi aten hta galai ra na kun?
A: Hkamja lam masa gaw, shawng nnan na masat da ai atsam hta na 80% npu de hkrat sum mat ai shaloi, galai kau na. Dai aten hta, charge langai hta runtime gaw dan dawng ai hku kadun wa nna, degradation rate gaw grau lawan wa ai. Kaja wa -hkang ai bungli ni hta LFP battery ni a matu, ndai threshold hpe 3,000–5,000+ lang shingjawng ngut ai hpang du wa ai.
Asak galu dik htum na matu Engineering galaw da ai Battery hpe lata ai
Forklift a battery prat gaw nambat langai sha n re. Dai gaw, Chemistry lata ai lam, pack engineering, BMS hpaji masa, shani shagu galaw sa wa ai tara ni a shinggyin la lu ai mahtai rai nga ai. Grau galu ai service life lu ai operator ni gaw gara variable ni hpe shanhte hkang ai, gara hpe pack kata de design galaw ra ai hpe chye na ai ni rai ma ai.
Ndai kaw Polinovel gaw PO n ka shi yang, sanghpaw li hpa-awn shagu san ra ai ga san mali hpe gara hku htai ya ai:
Cell chemistry hte bung ai hkam sharang ai lam
Grade-A LiFePO4 cells ni hpe, pack hpe n hpaw shi yang, 3% hta n law ai (sh) maren sha re ai hte kata na hkam sharang lu ai atsam hpe garan tawn da ai. Gara forklift hkrang hta mung kayau kaya-grade (sh) B-stock cell ni n lawm ai.
SOC window hpe hkan sa ai
Anhte a BMS gaw 10–90% bungli galaw ai SOC window hpe n-gun jaw ai. Ndai gaw nameplate atsam a 10% daram hpe sak jaw kau ai raitim, shadawn sharam galu ai cycle prat hpe jaw ya ai. Window hpe application langai ngai a matu configure galaw mai ai, raitim engineering review n galaw ai sha jat na matu anhte hpaji jaw ga ai.
Katsi ai shara a matu katsi ai hpe hkang ai lam
PTC hpe hpawng de da ai katsi ai lam gaw Polinovel katsi ai-chain forklift battery hkrang yawng hta madang langai rai nna, BMS-5℃cell katsi ai npu hta charge hpe pat da ai. Laksan n re, add-on n re. Gawgap da ai.
