Peak power ngu ai gaw hpa rai ta?
Peka n-gun
SOP (State of Power) ngu ai gaw, battery pack langai a peak power masa hpe tsun mayu ai, dai gaw battery langai mi hpe tau hkrau masat da ai aten laman hta shapraw lu ai (sh) hkap la lu ai n-gun kaba dik htum re. Peak power hpe manu jahpu n bung ai npu hta power battery a charge hte discharging limits ni hpe jep joi na matu jai lang mai ai, power battery pack hte mawdaw n-gun lapran na shadawn shadang hpe grau kaja hkra galaw na matu ahkyak ai lit nga ai, wan jak a bai gram lajang ai braking function hpe grau law hkra galaw lu ai. Dai hta n-ga, battery ni hpe myit sawn sumru ai hku jai lang na matu, grai law hkra charge galaw ai hpe koi ai (sh) n-gun grau law ai, battery shim lum lam hpe grau kaja hkra galaw ai, battery prat hpe jat ya ai hpe koi gam na matu, ahkyak ai theoretical hte tatut jai lang mai ai manu ni mung nga ai. Raitim, battery langai a peak power gaw shim lum lam law law nga ai; ndai shimlam shadawn sharam kata na peak power sha gaw tatut hta ahkyak ai lam nga ai. Ndai daw hta, battery n-gun hpe pat shingdang ai battery parameters nkau mi hpe bawngban nna, battery shim lum ai hte peak power lapran na matut mahkai lam hpe sawk sagawn ai.
Temperature- hpe madung tawn ai pat shingdang ai lam ni
Electrolyte a conductivity hte anode hte cathode arung arai ni a shamu shamawt ai lam gaw nbung katsi ai hte galai shai wa ai majaw, battery a charge hte discharge power a ntsa tsang hpe hkra machyi shangun ai. Electrode ni a reaction rate gaw nbung katsi wa ai hte maren yawm mat wa ai. Temperature gaw electrolyte kata na ion ni hte electron ni a htawt sit ai lam hpe mung hkra machyi shangun ai. Ndai n-gun ni gaw nbung laru law wa ai hte maren jat wa nna, vice versa. Dai hta n-ga, nbung laru grai law ai rai yang, masat da ai nbung katsi ai lam hpe lai di ai rai yang, battery kata na chemical balance hpe hkra machyi shangun nna, battery shimlam hte seng nna manghkang byin wa na re.
Hkrang 8-31 hta madun da ai hte maren, battery a peak power gaw nbung laru hte galai shai mat nna, asan sha n-linear curve hpe madun dan ai. Peak power yawm mat ai hte maren, nbung katsi ai lam yawm wa ai, n-gun yawm wa ai. Peak power jat wa ai hte maren, nbung laru law wa ai majaw, nbung laru grai law ai majaw, katsi ai hpe n-gun n rawng hkra galaw ya ai, n kaja ai hku battery shim lum lam hte asak hkrung lam hpe hkra machyi shangun ai.
SOC- hpe madung tawn ai pat shingdang ai lam ni
Mungdaw Hkringmang Dap (SOC) a pat shingdang ai lam hpe, bungli galaw ai aten hta, battery hpe grai n-gun n-ja hkra galaw na matu hte, battery hpe shim lum hkra galaw na matu, grai law hkra n-gun n-jaw na matu hte, battery hpe n-gun n-rawng hkra galaw na matu, galaw da ai re. Peak power hte SOC lapran na matut mahkai lam hpe sawk sagawn ai shaloi, SOC ntsa na nbung katsi ai lam hte charge/discharge rate zawn re ai lam ni a n-gun atsam hpe mung SOC shadawn shadang a hkrak ai lam hpe grau kaja hkra galaw na matu myit yu ra ai. Hkrang 8-32 hta madun da ai hte maren, SOC law wa ai hte maren, charge n-gun yawm wa ai shaloi, n-gun jat wa ai. Ga shadawn, SOC range langai sha hta, SOC gaw 10% kaw nna 90% de jat wa ai shaloi, peak htum mat ai n-gun gaw 222W kaw nna 693W du hkra jat wa ai, peak charge n-gun gaw 675W kaw nna 300W de yawm mat wa ai. SOC masa n bung ai npu hta peak power hpe hkaja ai gaw battery a charge/discharge atsam hpe sawn shapraw lu ai, wan jak mawdaw ni hta lang na matu data hte hpaji masa hku nna madi shadaw ya lu ai.
Ohmic ninghkap ai lam hpe madung tawn nna pat shingdang ai lam ni
8-33 hta madun da ai hte maren, battery langai a peak power gaw shi a ohmic kata na ninghkap ai lam hte shingdaw yu yang, shadawn shadang hku nna shadawn shadang nga ai. Ohmic kata na ninghkap ai lam kaji wa yang, peak power grau kaba wa nna lawan ai; ohmic kata na ninghkap ai lam kaba wa yang, peak power kaji nna n-gun yawm wa ai.
Battery a nbung katsi ai lam, manu jahpu masa (SOC), hte kata lam ninghkap ai lam ni yawng gaw shi a shimlam masa hte grai ni htep nga ai. Dai majaw, battery a bungli galaw ai masa (SOP) gaw, shim lum ai hku galaw lu na matu hte shi a asak hpe galu kaba wa hkra, ndai lam masum a majaw pat shingdang ai lam ni hpe hkan sa ra ai.
