Wanem samting i save mekim EV i sasim taim? 4-pela bikpela samting
1. Bateri Kapasiti: "Total" na "Usable" Gap
Olgeta samting i stat wantaimkapasiti bilong bateri, we mipela i skelim long kWh. Em i nambawan samting we i save mekim 'charging clock' bilong yu. Long ol isipela tok? Moa kapasiti i wankain olsem moa taim bilong sasim. Wanpela liklik bateri em i wanpela samting we i save pulap hariap; wanpela bikpela em i wanpela maraton.
Ol namba bilong ol buklet inap long giamanim yu. Sais bilong bateri i no wankain olsem yu inap long yusim. Planti EV i save putim wanpela liklik "sefti net" long sait bilong lukautim bateri i stap gut long ol yia i go pinis. Dispela i min olsem 'usable capacity' bilong yu i save stap daunbilo long ofisel reiting. Kisim wanpela 82kWh bateri-yu bai gat 77kWh tasol bilong wara tru. Long wanpela standet 7kW saja, dispela spes we i lus em i wanpela aua moa bilong taim bilong yu.
2. Stet bilong Sas (SoC): Dinamik Variabol
I no olsem wanpela bensin tenk, wanpela EV bateri i no save pulap long wankain spit. Em nauStet bilong Sas (SoC)i makim stret hamas pawa em inap long holim long wanpela taim.
Planti EV i save kamap long bikpela spit taim bateri i klostu pinis, tasol bai yu lukim olsem bateri i go daun tru taim yu winim mak bilong 80%. Dispela em i no wanpela hevi-em i wanpela sefti muv we ol i tingting long mekim. Sistem bilong kar i save daunim pawa bilong bosim hat i go antap na lukautim ol sel long bagarap longpela taim. Dispela i eksplenim as na laspela 20% i save kisim wankain taim olsem namba wan 80%.
3. Pawa bilong sasim (kW): "Weakest Link" Rul
Wanpela saja i ken tok olsem em i gat bikpela namba, tasol dispela em i hap stori tasol. Spid bilong yu i stap long tupela samting: autput bilong saja na intake siling bilong kar yet. Tingim olsem em i wanpela paip. Wanpela bikpela pam bai no inap helpim sapos "paip" bilong kar i liklik tumas long karim wara i ron.
Long sasim AC, 'on-board charger (OBC) bilong kar em i save pasim yu. Olsem, sapos wanpela EV inap long kisim 7kW AC sasing tasol, em bai sasim yet long 7kW maski em i putim long 22kW AC saja. Wankain tingting i kamap long DC 'fast charging'. Wanpela saja i ken gat 150kW o 250kW, tasol kar bai kisim tasol pawa we bateri sistem bilong en i ken kisim.
4. Envairomen Penalti: Tempereja olsem wanpela Efisiensi Multiplaia

Long taim bilong kol, bateri i no save wok isi na i mas hat pastaim long em i ken sasim hariap. Bikpela hat em i nogut wankain. Sistem bai tingting long pulim spit i go bek long stopim bateri long kukim em yet. Long dispela as yu ken kisim wanpela laitning-spit 'charge' long wanpela de na wanpela 'slow trickle' long narapela de, maski yu stap long wankain stesin stret.
Sampela nupela EV i save yusim 'battery preconditioning' long bringim 'pack' i go klostu long gutpela tempereja bilong en pastaim long ol i stat long sasim.
Hau long skelim taim bilong sasim EV
Yu ken yusim wanpelabesik fomulalong kisim gutpela namba bilong AC sasim. Em i gutpela long mekim ol 'rough planing'. Tasol, em i wanpela estimet tasol, long wanem, spit bilong sasim tru inap senis wantaim stet bilong sasim, tempereja bilong bateri, na mak bilong sasim kar.
Long yusim dispela fomula stret, yu mas kliagut long wanem samting wanwan veliu i makim insait long wanpela 'real-world seting:
- Bateri Kapasiti:Dispela i makim 'Usable Capacity' (olsem, 77kWh), i no olgeta fisikel sais (olsem, 82kWh), long wanem, kar i gat wanpela sefti bafa bilong lukautim laip bilong sel.
- Kapasiti i stap yet:Eneji bilong nau i stap yet insait long bateri bilong yu (olsem, sapos yu stap long 10%, kapasiti bilong yu i stap yet em 7.7kWh).
- Pawa bilong sasim:Maksimum autput bilong stesin (olsem, wanpela 22kW wolboks).
- Reit bilong kisim sas:Maksimum intake we kar bilong yu inap long karim. Long AC sasim, dispela em i On-Bod Saja (OBC) bilong yu.
👉Eksampel:
Wanpela 22kW Saja na wanpela EV Limited long 11kW AC Sajing (Dispela eksampel i soim ol maket we i gat tripela-feis AC sajing.
- Inap bilong bateri we yu ken yusim: 77kWh
- Stat bilong sas bilong nau: 10%
- Taget stet bilong sas: 80%
- Autput bilong saja: 22kW
- Mak bilong sasim AC bilong kar: 11kW
Pastaim, skelim strong yu nidim:
77 × (80% - 10%)=53.9kWh
Orait yusim liklik pawa bilong sasim -:
min(22kW, 11kW)=11kW
Taim bilong sasim:
53.9 ÷ 11=inap 4.9 aua
Dispela eksampel i soim as na wanpela 22kW AC saja i no save daunim taim bilong sasim. Sapos kar inap long kisim 11kW AC pawa tasol, dispela ekstra saja kapasiti bai no inap long yusim gut.
Bilong wanem EV Charging i save go daun bihain long 80%?
A sasim-taim fomulai givim yu wanpela estimet, tasol trupela EV sasing i no linear. Long planti EV, ol i save sasim hariap tru taim ol i sasim liklik o namel, na bihain i save go isi taim bateri i kamap long 80%.
