Luna e mai scump, dar e cu voltaj mare (deci amperaj mic), protecții peste protecții, inclusiv dispozitiv de stingere automata in caz de foc. Plus mulți ani garanție. Nu se compara cu baterii de-alea chinezești luate la bax.

Eu am GO-e, care sunt si cei care fac Fronius Wattpilot. Daca ai panouri, e mai simplu sa iei un wallbox facut de cei care fac si invertorul, pentru ca ar trebui sa fie mai simplu sa incarci din surplus, de exemplu. Modelul meu nu se mai fabrica, a fost inlocuit de asta.

apocalipsa electrica Countdown to Extinction
mgi replied to FiveThreeFive's topic in Opinii si editoriale
Dubios, la mine se deschide fara paywall. Stai sa caut un citat ❝ CATL has unveiled upgraded battery cells it claims can offer faster charging for electric vehicles than its rival BYD, putting the two Chinese groups ahead of competitors in the race to overcome a major barrier to the shift away from petrol vehicles. The world’s biggest electric vehicle battery maker said on Monday that a new version of its flagship Shenxing battery cell could offer a 520km range from just five minutes of charging time. Last month, BYD shocked the industry by unveiling a charging system that could add about 470km in range to its batteries in about the same time. The claims by the Chinese battery groups would put them ahead of major western rivals. At present, Tesla vehicles can be charged up to 200 miles (321km) in added range in 15 minutes, while Germany’s Mercedes-Benz recently launched its all-electric CLA compact sedan, which can be charged for up to 325km within 10 minutes using a fast-charging station. Analysts have said the deployment of high-speed charging systems from BYD and CATL will help to eradicate consumer fears about EV driving range, even though there are questions as to how fast the companies can bring these technologies outside China amid rising geopolitical tensions. The second generation of the Shenxing battery, which boasts a range of 800km on one charge, can achieve a peak charging speed of 2.5km per second, the company said at a media event ahead of this week’s Shanghai auto show. “We look forward to collaborating with more industry leaders to push the limits of supercharging through true innovation,” said CATL’s chief technology officer Gao Huan, adding that he wanted the new batteries to become “the standard for electric vehicles”. Analysts at Bernstein said the latest progress meant that charging speeds had more than doubled in the past year and “increased tenfold over the past 3-4 years”. Huan said the new Shenxing battery would be installed in more than 67 EV models this year. He later told reporters that energy density would not be sacrificed as a trade-off for fast charging. During its tech day, CATL also unveiled its new sodium-ion battery, which it said would go into mass production in December. The battery brand called Naxtra is able to give a range of about 200km for a hybrid vehicle and 500km for an electric vehicle, according to Huan. Sodium-ion batteries are seen as a cheaper and safer alternative to the lithium-based batteries widely used for energy storage, because they work better at both very high and low temperatures. But the amount of energy they can produce relative to their size has long lagged behind lithium batteries, making sodium cells impractical until now. The new technology has also been closely watched as a potential solution to reduce the world’s dependence on China for critical minerals, since sodium-ion batteries do not use lithium resources. At the event, Huan claimed the new sodium-ion battery would enable the industry’s shift from “single resource dependence” to “energy freedom” and reshape the global energy landscape. He added that he was in discussions with several companies about using sodium-ion batteries in their vehicles. ❞ Si in acelasi timp: https://technode.com/2025/04/22/catl-says-its-next-gen-dual-power-ev-battery-will-give-930-miles-of-range/- 3832 replies

De acord in general, cu exceptia LL19-FE, care e un LL04 imbunatatit de fapt.

Nu mai exista "ulei pentru diesel", contează cum e proiectata generația respectiva de motoare și cum e exploatata mașina

Eu as pune LL19-FE 0W30 sau LL04 0W30 (daca gasesti) sau 5W30, in ordinea asta a preferintelor.

DIn cate inteleg, unul dintre accidente a fost cauzat de un imbecil caruia i s-a aprins becul de carburant in mers si a decis sa opreasca pe banda 2 pe autostrada ca sa vada ce e. Nu stiu daca legea permite, dar sper sa-i anuleze permisul.. https://www.ct100.ro/accident-cu-opt-masini-pe-autostrada-motivul-incredibil-care-a-stat-la-baza/

Da-i in judecata, sef, vin si eu in sala sa rad. Mai ales la partea in care te-au obligat sa cumperi masina :))

Asta e un cablu type2 la type2, iti trebuie o statie de incarcare pentru el.

B47/25d 2019 motor distrus - pompa ulei
mgi replied to FanBMW76's topic in Probleme tehnice si rezolvari Seria X
Urat. E prima oara cand aud de un B47 crapat in felul asta. Si ma si mir ca dealer-ul a dat doar 6 luni garantie. Acum grija la luat motorul nou, as recomanda unul cu garantie daca nu l-ai cumparat deja. -
Iar discutia asta? Chiar presupunand ca ajungi la fel ca un non-plugin, daca mergi 80% in oras si restul in afara, media de consum tot o sa fie *mult* mai mica la un plugin.
-
Toate bateriile la bmw sunt NMC. însă poți liniștit sa încarci pana la 100% pentru ca exista un buffer mai mare ca la BEV, care preia degradarea. Și poți sa o și golești cât vrei, n-o sa ajungă de fapt la zero niciodată.
-
Cum sa nu fie? Am facut multe ture de 3-4,000 km cu al meu, cu trecut munti si asa mai departe. Zero probleme, zero emotii negative.
-
Cum sa treaca seria motorului?? Dar pe cea a bateriei nu, in cazul asta?
-
Da, depinde de turatie *si* cuplu. Dar Diferenta intre min si max e undeva sub 20% pe toata plaja de functionare, iar practic e probabil spre 10-12% pe baza de optimizari de soft, limitari de vmax si asa mai departe. Deci as zice ca nu e foarte relevant in contextul asta.. Masinile cu doua motoare in general au motoare diferite ca sa poata sa decupleze unul dintre ele si/sau ca sa faca coasting mai usor. Posibil sa fie si diferenta de consum la acceleratie, dar asta e in functie de parametrii specifici ai fiecarui model/motor si nici nu cred ca sunt publice datele astea.
-
Tehnic vorbind, ambele afirmatii sunt incorecte. Un motor electric are aceeasi eficienta la orice turatie/viteza. La masina termica insa, eficienta e mult mai proasta la viteza mica si creste odata cu cresterea vitezei. Dupa care intervine rezistenta aerului, care se aplica in ambele cazuri. Doar ca la electrice, majoritatea avand bateria sub podea, amprenta frontala e semnificativ mai mare. Deci imping mai mult aer si rezistenta creste cu patratul vitezei. Electrica are si ea racire activa, deci poti s-o abuzezi suficient de mult. Factorul limita o sa fie in 99% dintre cazuri capacitatea bateriei, nu faptul ca s-a incins motorul sau bateria.
