Remote diagnostics tih hi eng nge ni?
He sumdawnna hi kum 2016 khan ka lut a, chutih lai chuan battery atana remote diagnostics chungchang hi tumahin an sawi tak tak lo. Bus atang chuan pack kan la chhuak a, bench testers te pawh kan la hook up bawk. Tunah chuan ka kar chanve chhung chu dashboards en rengin ka hmang ta a.
Remote diagnostics tih awmzia chu battery pack chhunga thil thleng chu khawih lovin i hmu thei tihna a ni. BMS hian cell tin atangin voltage leh temperature a khawlkhawm a, a package a, Cellular chungah server pakhatah a thawn a, khawi emaw laiah a thawn chhuak thin. Chu chu a simple version a ni.
Version buaithlak takah hian eng data nge pawimawh tak tak tih chungchangah inhnialna tam tak a awm a.
A bulpui ber .
Pack khata cell tin hian voltage an nei vek a. 400V bus battery ah chuan cell 96 in series i nei thei. BMS hian pakhat zel an chhiar a, a tlangpuiin second tlemte chhungin an chhiar thin. Module hrang hranga thermistors theh darh atanga temperature a chhiar bawk. Module khatah sensor pakhat a awm mai thei, a aia tam pawh a ni mai thei, pack designer chu hot spot chungchangah paranoid a nih chuan.
Heng zawng zawng hi data stream ah a lut vek a ni. Stream chu a compress a, modem hmangin a nawr chhuak thin. LTE hian khawpui tam zawkah chuan a thawk tha hle. Out in the sticks I mamawh mai thei satellite mahse dik tak chuan fleet operator tam zawk chuan an truck-in thingtlang kawng a kah chuan data gap te chu an pawm mai thin.
Receiving end chu OEM-in cloud service a siam apiang a ni. AWS, could be azure, chu tumahin an enkawl duh loh thil engemaw tak a ni thei. Data chu database-ah a tla thla a, chutah chuan algorithms-in a chew leh a ni.

Eng nge kan zawn tak tak .
Cell voltage spread hi a lian ber a ni. Cell 96 i neih chuan pack a chawlh laiin an inhnaih vek tur a ni. Millivolt 10 emaw 15 emaw a inhlat mai thei. Cell pakhat chu a ṭhenawmte nena khaikhin chuan a hniam ṭan chuan, chu cell chu a dang zawng aiin a chhe rang zawk a ni. A tawpah chuan i pack capacity a tihtlem dawn a ni.
Lum leh vawt tehna
Mite ngaihdan aiin temperature a tricky zawk. Sensor pakhat chuan 35℃a chhiar thei a mahse cell surface tak tak inches hnih a hla chu 40℃a ni thei . I interpolate a ni. I lo guess dawn a ni. Algorithms te hian hei hi an account a mahse rinhlelhna a awm fo thin.
Internal resistance .
Internal resistance hi health assessment atana gold standard a ni a mahse production BMS system tam zawk chuan an teh tha lo. Controlled current pulse leh clean voltage reading i mamawh a ni. Lirthei chu highway-a a tlak lai chuan tih harsa tak a ni. System thar zawk thenkhat chuan engkim a stable laiin charge laiin an ti thin.
Tuman an hrilh che part chu .
Alerts ka hmuh zatve chu bawlhhlawh a ni. BMS firmware-a sensor a chhiat, connection loose, software glitches. Technician pakhat chuan system chu critical anga flag leh thil dik lo a hmuh loh battery check turin a tlan chhuak a. Thermistor hian solder joint tha lo tak a nei a. Darkar thum vel hmanral a ni.
Remote diagnostics tha tak neih a ngai a, filtering a ngai bawk. Data filter mai ni lovin alerts te filter a ni. Tu emaw i buai hmain signal tam tak i correlate a ngai a ni. Temperature sang tak pakhat chhiar hian engmah a kawk lo. Current a hniam a, ambient a normal laiin a zawnin reading pathum trending up a ni a, chu chu phone call tlak a ni.
Ohio-a transit agency pakhat nen kum hnih vel zet kan thawk dun a. Electric bus 40 an nei a, kan tan tirh khan kar khatah alerts 200 vel an dawng mai thei. A tam zawk chu false positive an ni. Thresholds te chu kan tuned a, hun engemaw chen kan dah belh-based logic, kar khatah alerts 30 vel ah kan dah a. Chumi zinga 20 chu actionable an ni mai thei.
Sum zawhna chu .
Fleet manager te chuan ROI chungchang an zawt fo thin. Hetah hian chhanna dik tak chu a awm: i baseline a chhiat danah a innghat.
- Thla tin inspection leh catching problems i tih hmasak tawh chuan remote diagnostics hian kum khatah kawngpui sira failure tlemte chauh a chhanhim thei che a ni. Subscription costs chu pencil out a ni lo mai thei.
- An thih thlenga pack i run a, chutah chuan reacting i neih chuan remote diagnostics chuan a man a pe nghal vat ang. Fleet-te chuan tow truck, fire department call, leh emergency shipping-a replacement pack tihna tur catastrophic failure an pumpelh ka hmu tawh. Mi pakhat chuan thermal event a pumpelh a, thla tin fee tam tak a huam a ni.
Savings harsa zawk chu quantified a ni. Continuous data i neih chuan pack hman dan dik tak i finfiah thei ang. Customer hian khaw lum laiin fast charging hmangin a hmang sual em? Data chuan a tarlang. Manufacturer chuan cells a ti chhe tawh em? Data atanga a lan dan chuan chu pawh chu.
khawiah nge hetiang hi a kal dawn.
"Machine zirlai thil hi ka ngaihdan chuan overhyped a ni."
Electrochemical impedance spectroscopy chu research paper-ah a rawn lang chhuak zel a. Ngaihtuahna chu frequency hrang hranga AC signal inject a, response teh a ni. Lithium plating ang chi thil hi voltage data-a a lan hmain i detect thei a ni. Company tlemte chuan he thil hi productize an tum a mahse volume production lamah erawh engmah ka la hmu lo.
Machine learning thil hi ka ngaihdan chuan overhyped a ni. Yes Historical failure data ah model i train thei. Mahse battery te hi kawng thar leh thil siam chhuah kawngah an hlawhchham thin. Kum 2020-a data hmanga trained model chuan kum 2024-a chemistry-a lang failure mode-te chu a hloh mai thei. Mihringin data a en a, zawhna i zawh a ngai reng a ni.
Ka duh tak tak chu sensor tha zawk hi a ni. Cell chhunga pressure awm dan direct measurement min pe rawh. Electrolyte tihchhiat hmasakna tur gas sensor min pe rawh. Tuna BMS data kan neih hi damlo hriselna hriat tum ang mai a ni a, an temperature leh pulse chauh teh a ni. A tangkai viau nain a kim lo.
Thurawn hmantlak tak tak .
Battery system i spec'ing a, supplier chuan remote diagnostics chu option atan a pe a nih chuan la rawh. I hmang ngei ang tih i chiang lo a nih pawhin. Data retroactive taka neih hi a hlu hle. Telemetry tel lo pack hlawhchham chunga thil thleng chu siam thar leh tum chu a hrehawm hle.
Data neitu chu i hriatthiam ngei ngei tur a ni. Supplier thenkhat chuan an platform-ah an khar a, nangmah ngeiin information i hmuh theih nan an charge che a ni. Contract-ah hian data export rights a hmu.
Cellular costs chungchang zawt rawh. System thenkhatah chuan data plan a awm a, thenkhat chuan an ti lo. Device za tlemte transmitting chuan a adds up reng thin.
leh mi pakhatin dashboards a en tak tak tur budget a siam bawk. A fanciest diagnostics platform hi tumahin an log in loh chuan hlutna a nei lo.
