Battery C-rate hi battery charging emaw discharging emaw speed tehna unit a ni a, charge/discharge rate tia hriat a ni bawk. A bik takin, C-rate hian battery-a charge/discharge current leh a rated capacity inzawmna tam tak a entir a ni. Calculation formula chu:
Charge/Discharge rate = charge/discharge current / rates theihna .
Definition: C-rate, charge/discharge rate tia sawi bawk hi charge/discharge current leh battery nominal capacity ratio a ni. Entirnan, battery rated capacity 100AH nei tan chuan current 20A-a discharging hi discharge rate 0.2C nen a inmil a ni.
Hriatthiamna: Discharge C-rate, 1C, 2C, emaw 0.2C ang chi hian discharge speed a tarlang a. Rate 1C tih hian battery chu darkar khat chhungin a discharge kim thei tihna a ni a, 0.2C chuan darkar nga chhunga discharge a nih thu a tarlang thung. A tlangpuiin battery capacity tehna atan hian discharge current hrang hrang hman theih a ni. 24AH battery atan chuan 2C discharge current chu 48a a ni a, 0.5C discharge current chu 12A a ni thung.
Performance Testing: C-Rate hrang hranga discharging hmang hian battery parameters te chu capacity, internal resistance, leh discharge platform ang chi test theih a ni a, hei hian battery quality leh lifespan te a tehna a pui thei a ni.
Application Scenarios: Application scenario hrang hrangah C-rate mamawh hrang hrang a awm a. Entirnan, electric lirthei chuan fast charge/discharge atan C-rate battery sang tak a mamawh a, energy storage system-ah chuan dam rei leh man a pawimawh ber a, C-rate charging leh discharging hniam zawk an thlang fo bawk.
Cell a thawh dan .
Cell capacity: C-rate chu a bul berah chuan charge/discharge current leh cell rated capacity ratio a ni. Chutiang chuan cell capacity hian C-rate chu direct-in a tichiang a ni. Cell capacity a lian poh leh discharge current ang chiah C-rate a hniam zawk a, a lehlamah pawh a hniam zawk bawk.
Cell material leh structure: Cell material leh structure, electrode materials te, leh electrolyte type te hian charge/discharge performance a nghawng a, chu chuan C-rate a nghawng a ni. Material thenkhat chuan high-rate charging leh discharging an support thei a, thenkhat erawh chu low-rate application atan a tha zawk thei bawk.
Battery pack design a ni bawk.
Thermal Management: Charge/discharge lai hian battery pack hian lumna nasa tak a siam a. Thermal management a tlem chuan chhung lam boruak lum a sang ang a, charge power a tihtlem bakah C-rate a nghawng ang. Chuvangin, battery-a C-rate tihsan nan thermal design tha tak neih a pawimawh hle.
Battery Monitoring System (BMS) : BMS hian battery a enkawl a, a enkawl a, chung zingah chuan charge/discharge, temperature, etc. controlling charge/discharge current leh voltage dik taka control a, BMS hian battery performance a ti tha a, chu chuan C-rate a ti tha zawk a ni.
Pawn lam dinhmun .
Ambient Temperature: Battery performance-ah hian boruak lum hi a pawimawh hle. Temperature hniam takah chuan charging speed a slow a, discharge capacity a khap a, C-rate a ti tlem bawk. A lehlamah chuan, temperature sang takah chuan overheating hian C-rate a nghawng thei bawk.
Battery’s State of Charge (SOC): Battery a SOC a hniam chuan charging hi a rang zawk duh a, internal chemical reaction resistance a hniam deuh avangin. Mahse, full charge a hnaih deuh deuh chuan, overcharging loh nan precise control a ngaih avangin charging speed chu a tlahniam zauh zauh a ni.
C-rate hi condition hrang hrang hnuaia battery performance hriatthiamna atan a pawimawh hle. C-rates hniam zawk (eg, 0.1C emaw 0.2C) hi hun rei tak chhunga charge/discharge test nan an hmang fo thin a, chu chu an theihna, an thawh thatna leh an dam chhung tehna atan an hmang thin. C-rates sang zawk (eg, 1C, 2C, or more) te hian battery performance chu fast charge/discharge mamawhna atan an zirchiang a, chu chu electric vehicle acceleration emaw drone flight emaw a ni.
C-rate sang zawk hi a tha zawk ngai lo tih hriat a pawimawh. C-rate sang hian charge/discharge chak zawk a siam theih laiin, a chhiatna tur a thlen thei bawk a, chu chu efficiency tihtlem, lumna tihpun leh battery dam rei lo zawk te a ni. Chuvangin, battery thlan leh hman hunah chuan C-rate chu application bik leh mamawh ang zela performance parameter dang nena balance a pawimawh hle.
