Chemical power sources ni a madung electrochemical atsam ni gaw, atsam, n-gun, kata na n-gun, tinang hkum hpe ninghkap lu ai atsam, tinang hkum hpe ninghkap lu ai atsam, shinggyin la lu ai atsam, n-gun kaba ai hte n-gun n law ai nbung n-gun npawt nhpang langai hku nna, n-gun atsam battery ni hta mung, charge hte n-gun dat galaw ai lam, cycle a bungli galaw ai lam, kata na n-gun, n-gun atsam, etc. ni lawm ai. hte n-gun chyam dinglik ai lam, shinggyin tawn da ai lam hte self{3}discharge chyam dinglik ai lam, asak hkrung lam hpe chyam dinglik ai lam, kata na n-gun hpe chyam dinglik ai lam, kata na n-gun hpe chyam dinglik ai lam, shim lum lam hpe chyam dinglik ai lam ni, etc.

From the perspective of actual vehicle application, a series of tests suitable for vehicle use are carried out with the power battery pack applied to electric vehicles as the test object, such as: static capacity detection, dynamic capacity detection, quiescent test, starting power test, rapid charging capability test, cycle life test, safety test, battery vibration test, peak power detection, partial discharge detection, maximum gradient power test, thermal performance test, etc.

(1) Static atsam marai hpe sawk sagawn ai Ndai chyam dinglik ai lam a madung yaw shada ai lam gaw, power battery pack hta mawdaw hpe teng sha jai lang ai shaloi, manu jahpu hte n-gun atsam law law nga ai hpe chye na lu na matu rai nna, tau hkrau masat da ai hka lim ai lam hte nbung laru amyu myu a npu hta, shinggyim masha ni zawn bungli galaw lu ai. Madung chyam dinglik ai ladat gaw, n-gun n-htum ai nbung laru masa ni a npu hta, n-gun shayawm ai chyam dinglik ai lam hpe shayawm ya ai, n-gun n-gun n-gun n-gun (voltage) gaw set value de hkrat mat ai (sh) power battery pack (voltage shai hkat ai lam) kata na cell langai a n-gun n-gun (voltage shai hkat ai lam) a n-gun hpe set value de du hkra galaw ai shaloi, n-gun yawm mat ai.

(2) Dynamic atsam marai hpe sawk sagawn ai lamWan jak mawdaw langai a bungli galaw ai aten hta, wan n-gun a n-gun hte n-gun dat n-gun gaw n-gun rawng ai. Ndai chyam dinglik ai lam gaw madung hku nna, n-gun rawng ai n-gun hte n-gun n bung ai shara ni hta n-gun atsam hte n-gun atsam hta madung hku nna dan dawng nga ai, n-gun rawng ai n-gun atsam hpe mu lu ai. Madung chyam dinglik ai ladat gaw, tau hkrau masat da ai current profile (sh) mawdaw a application kaw na teng sha shinggyin la ai ya na profile hpe lang nna, power battery pack hpe discharge galaw ai lam hpe chyam dinglik ai lam galaw na matu re. Ndai chyam dinglik ai lam a jahkring kau ai masa hpe chyam dinglik ai masa hte power battery a arawn alai ni hpe hkan nna gram lajang ai raitim, madung hku nna gaw manu langai ngai de hkrat sum ai voltage a madang hpe hkan sa ai. Ndai ladat gaw, wan jak mawdaw ni a teng sha jai lang ra ai lam ni hpe grau hkrak hkra, hkrak hkrak madun dan lu ai.

(3) Quiescent TestNdai chyam dinglik ai lam a yaw shada ai lam gaw, aten ladaw langai mi tup n lang ai sha, power battery pack a capacity sum mat ai hpe mu lu na matu re, dai hpe wan jak mawdaw hpe aten kadun laman n shadut ai sha, battery hpe hpaw tawn da ai masa hpe shingdaw na matu lang ai. Ndai quiescent chyam dinglik ai lam hpe self{2}} n-gun n-gun hte shinggyin tawn ai bungli galaw ai lam hpe chyam dinglik ai lam ngu nna mung shamying ma ai, dai gaw battery a n-gun hpe hpaw da ai-}circuit masa hta nga ai shaloi, grup yin masa nkau mi a npu hta tawn da ai atsam hpe tsun mayu ai.

(4) N-gun atsam chyam dinglik hpang ai lam Mawdaw langai a npawt nhpang n-gun gaw grai kaba ai majaw, mawdaw a npawt nhpang hpe n bung ai nbung laru masa hta hkan nna hkan sa na matu, n-gun n-gun n-gun n-gun n-gun n-gun n-gun ($−18\\text{℃}$) hte nbung n-gun kaba ($50\\text{℃}$) hpe hpaw hpang ai. Ndai chyam dinglik ai lam gaw, nta kata na nbung katsi ai shara hta shadawn ai hta n-ga, manu jahpu garan ai masa amyu myu hta battery a pru wa lu ai atsam hpe chye lu na matu SOC manu hte mung masat da ai. Common tests ni gaw $90\\%$, $50\\%, $20\\% SOC hte galaw ai power test ni re.

(5) Rapid charge galaw lu ai atsam hpe jep joi ai lamNdai chyam dinglik ai lam a yaw shada ai lam gaw, power battery pack hta n-gun kaba ai{0}}rate charge chyam dinglik ai lam ni hpe galaw ai hku nna, battery a lawan ai charge galaw lu ai atsam hpe chyam yu na matu, shi a akyu, katsi ai lam, kaga nta ni hpe hkra machyi shangun ai lam ni hpe jep joi na matu re. Lawan ai hku charge galaw na matu, USABC madang gaw battery SOC hpe $40\\% kaw nna $15\\text{min}$ laman $80\\% de bai lu la na matu yaw shada ai. Ya aten hta, Japan a CHAdeMO hpung kaw nna masat da ai madang hta, wan jak mawdaw n-gun battery pack hpe $10\\text{min}$ daram hte charge galaw na matu ra sharawng ai gaw, mawdaw gaw $50\\text{km}$ hpe $50\\text{km}$ de hkawm sa lu na re; $30\\text{min}$ hte charge galaw ai gaw mawdaw hpe $100\\text{km}$ hku hkawm sa lu na hpe kam mai ai.
