Salutare!

Vreau și eu un sfat, in cazul in care v-ați lovit de așa ceva. Se poate face testare pentru bateria de tracțiune cu bimmertool sau bimmer link? Ce module se verifică pentru a vedea posibilele erori sau uzura la bateria de tracțiune?

Si eu sunt interesat

Up?

Cred ca cel mai safe mergi la un atelier ca nu cred ca poti verifica celulele altfel

Salut,

Starea bateriei de tractiune se determina la BMW cu o scula speciala care costa multe mii de euro conectata la ISTA executandu-se o procedura de descarcare la 0 si incarcare la 100%

Bimmerlink are o aplicatie separata care se cheama parca EvScaner dar care dupa cate vad nu face altceva decat sa interogheze BMS-ul masinii. Acest lucru il face si ISTA, cel putin versiunile mai noi, si le poti vedea in logul cu terminatia ".behdat" daca ai putina rabdare sa cauti prin el.

Arata ceva de genul :

Asata este la bateria mea azi, are aproape 6 ani si se tine bine zic eu...

Doar sa citesti tensiunile pe fiecare celula este absolut irelevant.

Cand celulele se debalanseaza prea mult, se seteaza DTC. Diagnoza asta doar indica intre care celule este diferenta cea mai mare.

Despre starea bateriei poti sa-ti faci maxim o informare cat de cat ok incarcand la DC si incepand de la un porcent cat mai mic (ex 5%) si o incarci pana la in jur de 90%

Te uiti cat ai incarcat in kWh si cate procente. Apoi cu regula de 3 simpla poti determina relativ precis cat mai are capacitate.

Pt testarea oficiala, doar incarcat/descarcat cu un echipament special si numai dupa ce s-au efectuat cativa ciclii de descarcare completa si incarcare completa pt ca testarea se face pe o baterie balansata. Nu la orice moment. Doar balansata complet.
