Dɛn ne akyirikyiri nhwehwɛmu ahorow?
Mekɔɔ saa adwuma yi mu wɔ 2016 mu bere a obiara anka akyirikyiri nhwehwɛmu a wɔde hwehwɛ batere ho asɛm ankasa. Ná yɛda so ara retwe pack ahorow afi bɔs ahorow mu na yɛakyere benkyi ho sɔhwɛfo. Seesei mede me dapɛn fã hwɛ dashboard ahorow.
Remote diagnostics kyerɛ sɛ wubetumi ahu nea ɛrekɔ so wɔ battery pack mu a womfa wo nsa nka. BMS no boaboa voltage ne temperature ano fi cell biara mu, ɛboaboa ano, ɛde kɔ cellular so kɔ server bi so wɔ baabi. Ɛno ne version a ɛyɛ mmerɛw no.
Nea ɛyɛ den no hwehwɛ sɛ wogye akyinnye pii fa nea data ho hia ankasa ho.
Nneɛma atitiriw no .
Cell biara a ɛwɔ pack mu no wɔ voltage. Wɔ 400V bɔs battery mu no ebia wowɔ 96 cells wɔ series mu. BMS no kenkan emu biara, mpɛn pii no simma kakraa biara. Ɛsan nso kenkan ɔhyew fi thermistors a wɔahwete wɔ module ahorow no ho. Ebia sensor biako wɔ module biara mu, ebia na ɛboro so sɛ pack designer no yɛ paranoid wɔ hot spots ho a.
Eyi nyinaa kɔ data stream mu. Asuten no mu yɛ den na ɛpia no fa modem bi mu. LTE yɛ adwuma yiye wɔ nkurow dodow no ara mu. Out in the sticks ebia wubehia satellite nanso nokwarem no dodow no ara po so ahyɛn adwumayɛfo gye data gaps no tom ara kwa bere a wɔn lɔre ahorow no kɔ nkuraase akwan so no.
End a wogye no yɛ cloud service biara a OEM de asi hɔ. Could be aws, could be azure, betumi ayɛ biribi a ɛyɛ ne dea a obiara mpɛ sɛ ɔbɛhwɛ so. Data no si fam wɔ database mu na afei algorithms chew wɔ so.

Nkwammoaa mu ahoɔden a ɛtrɛw no yɛ kɛse. Sɛ wowɔ cells 96 a ɛsɛ sɛ wɔn nyinaa bɛn wɔn ho wɔn ho yiye bere a pack no rehome no. Ebia na 10 anaa 15 millivolts ntam.

Musent resistance yɛ sika kɔkɔɔ gyinapɛn ma akwahosan nhwehwɛmu nanso dodow no ara production BMS nhyehyɛe nsusuw no yiye. Wo hia controlled current pulse ne voltage akenkan a ɛho tew. Ɛyɛ den sɛ wobɛyɛ bere a kar no rehuruhuruw wɔ ɔkwan kɛse no so no. Nhyehyɛe foforo no bi yɛ no bere a wɔrebɔ ka bere a biribiara gyina hɔ no.
Ɔfã no obiara nka nkyerɛ wo .
Alerts a mehu no fã yɛ nwura. Sensor huammɔdi, nkitahodi a ɛnyɛ den, software glitches wɔ BMS firmware no mu. Mfiridwuma ho nimdefo bi de kar kɔhwɛ batere bi a nhyehyɛe no hyɛe sɛ ɛho hia kɛse na onhu mfomso biara. Ná thermistor no wɔ solder joint bɔne. Nnɔnhwerew abiɛsa na wɔsɛee no.
Remote diagnostics pa hwehwɛ sɛ wɔde yiyi mu. Ɛnyɛ data no a wɔde yiyi mu kɛkɛ na mmom sɛ wɔbɛsesa alerts no. Ɛsɛ sɛ wo ne no hyia wɔ nsɛnkyerɛnne pii so ansa na woahaw obiara. Ɔhyew a ɛkorɔn akenkan biako nkyerɛ hwee. Akenkan abiɛsa a ɛtoatoa so a ɛrekɔ so bere a current no sua na ambient yɛ normal, ɛno fata telefon so frɛ.
Me ne adwumakuw bi a ɛhwɛ akwantu so wɔ Ohio yɛɛ adwuma bɛyɛ mfe abien. Na wɔwɔ bɔs a anyinam ahoɔden wom 40 na na ebia wɔrenya kɔkɔbɔ 200 dapɛn biara bere a yefii ase no. Ná dodow no ara yɛ atoro a ɛyɛ papa. Yɛyɛɛ no tuned thresholds, de bere bi kaa ho-gyina logic so, nyaa no kɔɔ fam koduu bɛyɛ 30 alerts dapɛn biara. Wɔn mu no, ebia na 20 yɛ nea wotumi yɛ ho biribi.

"Afiri a wɔde sua ade no yɛ nea wɔahyɛ no ma wɔ m'adwene mu."
Electrochemical impedance spectroscopy kɔ so ba wɔ nhwehwɛmu nkrataa mu. Adwene no ne sɛ wɔde AC nsɛnkyerɛnne bɛhyɛ mu wɔ frequency ahorow so na wɔasusuw mmuae no.

Machine learning stuff no hypled wɔ m’adwene mu. Yiw wubetumi atete mfonini ahorow wɔ abakɔsɛm mu huammɔdi data so. Nanso batere di nkogu wɔ akwan foforo ne adebɔ mu.

Nea mepɛ ankasa ne sensor ahorow a eye sen biara. Ma me nhyɛso tẽẽ a ɛfa nhyɛso a ɛwɔ nkwammoaa no mu ho. Ma me gas sensor ahorow a ebetumi ahu sɛ electrolyte a ɛpaapae ntɛm no.

Afotu a mfaso wɔ so .
Sɛ woreyɛ spec'ing battery system na supplier no de akyirikyiri diagnostics ma sɛ option a, fa. Sɛ mpo wunni ahotoso sɛ wode bedi dwuma a. Sɛ wowɔ data no retroactively a, ɛsom bo. Sɛ́ wobɛbɔ mmɔden sɛ wobɛsan ayɛ nea ɛtoo pack a entumi nyɛ yiye a enni telemetry no yɛ yaw.
