Tesla P85+ 2014 – Drive unit repair

Napokon i prvi elektromotor sa nekim kvarom. Legenda kaze da na 100000 defektnih N47 lanaca i milijon probušenih DPF-ova crkne jedan elektromotor. Ovdje je Sport Large Drive Unit od 310kW snage za vrijeme jakih kiša prethodnih dana na HV kabelu kraj brtve propustio vlagu u kućište invertera i došlo je do proboja izolacije i permanentne deaktivacije BMS sustava (repeated Isolation fault). Zadnji pogon se skida kompletno sa zadnjim Subframe. Odpuste se amortizeri i čeljusti, zatim 4 vijka i 2 crijeva od antifriza i sve je dolje u roku sat vremena. Motor je tezak nekih 150 kila i potreban je kran za vadjenje. Nakon otvaranja kućišta invertera bili su vidljivi tragovi vlage i proboja izolacije. Na motoru je bilo 1mOhm ISO a minimalno smije biti 5MOhm. Iako nije velika razlika bilo je vidljivo zaštitnom sustavu u BMS. Proboj izolacije znaci da 400V dira šasiju. Takodjer za napomenuti da je ovo vrlo često “ispiran” demant protiv ovog motora kako se “cesto u garanciji mijenjaju”. Tesla ima userfriendly praksu da bez obzira na bilo koji lako otklonjiv kvar, vlasniku montira reparirani refurbish motor a stari vraca u Itlburg na refurbish (da smanji cekanje). Neke preventivne operacije su se mogle implementirati da ovoj motor bez problema prelazi i 1mil kilometara.

ENGLISH

Finally, the first electric motor with some malfunction. Legend has it that for every 100,000 defective N47 chains and a million punctured DPFs, one electric motor fails. Here, the Sport Large Drive Unit of 310 kW power, during the heavy rains of the previous days, on the HV cable near the seal, leaked moisture into the inverter housing and there was a breakdown of the insulation and permanent deactivation of the BMS system (repeated Isolation fault). The rear drive is removed completely with the rear Subframe. The shock absorbers and calipers are released, then 4 bolts and 2 antifreeze hoses and everything is down within an hour. The engine weighs about 150 kilos and requires a crane to remove it. After opening the inverter housing, traces of moisture and insulation breakdown were visible. There was 1mOhm ISO on the motor, and the minimum must be 5MOhm. Although not a big difference, it was visible to the protection system in the BMS. Insulation breakdown means that 400V touches the chassis. It should also be noted that this is a very often “washed out” claim against this engine that “they are often changed under warranty”. Tesla has a user-friendly practice that, regardless of any easily rectifiable malfunction, it installs a repaired refurbished engine for the owner and returns the old one to Itlburg for refurbish (to reduce the wait). Some preventive operations could have been implemented so that this engine could easily exceed 1,000 kilometers.

DPF ili BATERIJA – što je zapaljivije

https://dieselnet.com/news/2011/10cleaire.php

Uzrok skoro svih paljevina na cesti su loše dizajnirani fosilci euro 5/6/7, većinom dizeli, zbog lančane reakcije visokog tlaka i visoke temperature na DPF-u gdje overpressure ispuha gura ulje iz kartera u glavu motora. Sa druge strane EV je uistinu po tom pitanju sigurniji i statistički i u realnom svijetu, jer su i sustavi tog pogona dizajnirani da rade u što sigurnijim uvjetima i režimima rada. Požar je na EV nekad ustinu teže ugasiti, ali ovaj slučaj dokazuje i suprotno. U jednom razgovoru sa vatrogasnim društvom Ivanić Grad imali smo eksluzivno povratne informacije o redovnim požarima fosilaca na naplatnim kućicama u Rugvici. Vožnja pod opterecenjem sa aktivnom regeneracijom dpf i naglo zaustavljanje, ako je sustav imalo neispravan tada dovodi do topljenja okolnog zapaljivog materijala u motornom prostoru. Ovdje na slici imamo jednu totalno nevjerovatnu priču, gdje je zbog greške električnog romobila došlo do požara u kućnoj garaži gdje su izgorila 3 vozila, 2 fosilca i jedan EV. Taj EV je bio Tesla Model S iz 2015, koji je u potpunosti izgorio do pragova i podnice ali je baterija preživjela nevjerovatne temperature preko 800 stupnjeva. Zbog topljenja unutarnje PVC konstrukcije 18650 ćelija (saće), sama konstrukcija je pod vlastitom težinom smotala i odvojila ćelije iz sigurne zone i spojila jednu paralelu sa drugom sto je uzrokovalo izgaranje kratkim spojem ali samo na jednom od 16 blokova. Znaci vanjska temperatura požara izvan vozila je istopila unutarnju konstrukciju i kratkim spojem izazvala pozar, koji je nevjerovatno ostao lokaliziran unutar njegove komore u samom battery pack. Sekundarni problem na baterijskom pogonu je nastao gasenjem pozara, gdje je voda kojom su gasili skoro zapalila jos jedan blok. Šteta od vode je nastala na još nekoliko blokova i kao cijelina nisu ispravni. Jedan blok ima 444 ćelije, i one su ispravne za daljnju upotrebu, skoro su sve izmjerene i ispitane. Mi smo vlastitim primjerom 4 reciklirali za neispravnu bateriju HP laptopa, ostale idu u novu kantu štroma, romobil, car starter itd itd. Ćelija ima 2850mAh na 1A discharge, internal resistance 400mOhm. Ako tko želi, ima još dostupnih. Svakako nevjerovatna priča koja govori dosta o sigurnosti baterija, izgorila je cijela garaža i sve u garaži, a preživjela je baterija, koja je sama lokalizirala pozar u jednom komori i spašen je kompletan zadnji elektromotor od 315kW za novi upotrebu u nekom swapu. Ostala 2 fosilca iz požara nisu imali ništa upotrebljivo. Primjeri Tesle koja se nije zapalila ni nakon drobljenja baterije u udesu: https://vm.tiktok.com/ZMFyktFLQ/

Cijena ćelija:

*EV je super: 2.2€

*EV je najsigurniji kad ne parkiras kraj bmw :2€

*EV je smeće : 50€ komad

Tesla battery repair BMS_U029

Nikola Tesla, happy birthday and thank you for all your innovations that you gifted to civilization. We chose this day for a stress test of the restored battery and a short get-together with DEMS in Smiljan, at your birthplace. After 2 months of defect research and distractions from faulty “just pour and drive” Hybrids we finished the second Tesla P85 2013 battery from Switzerland. Colleagues tried to solve the problem before, but without success, they don’t have Štrom Trooper Zlatni. In short, Tesla has the most rigorous BMS safety features ever seen in battery systems, it took us some time to figure out how the problem they call “weak short” or “short to brick” works (because we were the first to encounter it among all colleagues). The rule that says (I usually charge secret info) for the BMS_u029 error is: If the battery in idle state for a period longer than xx (approx. 8 or more hours) when checking any of the 96S bricks shows a linear voltage drop over time, then activate w117 and u029. That means, the check is activated ONLY if the vehicle is not used and in the system is one BRICK out of 76x 18650 cells in parallel and one of them has turned into a consumer. The damage is in principle €2-4. The problem is that we didn’t know which processor and memory saved the error flag/log and where the error transmission came from.
We located the block with “weekshort”, we put a ready second block with almost the same capacity and internal resistance in tausch and that fault was eliminated, there was still a BMS error u029 which we had to solve by changing the BMS board in the end because we don’t have a service seedkey reset command, i.e. there is no is none other than the refurbish factory in Tilburg. With error u029 he still drives and charges, but only up to 35% of the battery, preventive protection.
Failure: one 18650 Panasonic cell €2-4
Error: BMS_u029 and BMS_w117
BMS: 1021970-00-B rev3 €500
Mileage: 187,000 km (saving 13,000 L of diesel)
Model S p85 free charging lifetime
Authorized Full refurbish battery: €9,200+VAT
New Mercedes 320cdi engine: €27000 + VAT
New Mercedes 7729 gearbox: €10,000 + VAT
EV Clinic restoration: €4000 – €1000 discount
Discount sponsors:
Marko from Germany with a w212 hybrid
Josip with B47 Defect edc17 (hasn’t caught fire yet)
Ante Delco Opel does not see the cam sensor.
*battery system of any type almost never needs to be changed entirely, but the problem of individual components is eliminated.

Nikola Tesla sretan ti rodjedan i hvala ti na svim tvojim inovacijama koje si poklonio civilizaciji. Ovaj dan smo izabrali za stress test restaurirane baterije i kratko druženje u Smiljanu, tvojoj rodnoj kući. Nakon 2 mjeseca istraživanja defekta i ometanja od strane neispravnih “samo toči i vozi” Hybrida završili smo drugu Tesla P85 2013 bateriju iz Švicarske. Kolege su probale prije riješiti problem ali bezuspješno, nemaju Štrom Troopera Zlatnog. Ukratko, Tesla ima najrigoroznije BMS safety features ikad vidjene u baterijskim sustavima, trebalo nam je vremena da skužimo kako funkcionira problem koji oni zovu “weak short” ili “short to brick” (jer smo prvi se susreli medju svim kolegama). Pravilo koje glasi (ovo inače naplaćujem da peku oči) za BMS_u029 grešku je: Ako baterija u stanju mirovanja u periodu dužem od xx (cca 8 ili vise sati) prilikom provjere bilo kojeg od 96S bricka pokaže linearan pad napona kroz vrijeme tad aktiviraj w117 i u029. Tj provjera se aktivira SAMO ako se vozilo ne koristi a u sistemu postoji jedan BRICK od 76x 18650 ćelija u paralili i jedna medju njima se pretvorila u potrošač. Šteta je u principu 2-4€. Problem je što nismo znali koji procesor i memorija sprema provjeru i odakle je transmisija greške.

Blok sa “weekshort” smo locirali, spreman drugi blok skoro istog kapaciteta i unutarnjeg otpora smo stavili u tausch i taj kvar eliminiran, ostala jos BMS greška u029 koju smo na kraju morali riješiti promjenom BMS ploče jer nemamo service seedkey komandu za reset, tj nema je niko osim refurbish tvornice u Tilburgu. Sa greškom u029 on i dalje vozi i puni, ali samo do 35% baterije, preventivna zaštita.

Tesla battery repair BMS_F123

Our mission is proceeding as planed, aftermarket support for EV’s is in “3rd gear”. New German customer sent his Tesla P85+ from Tesla Service center to Zagreb Croatia, to try save the 9 years old battery. All battery defects are received over the line, waiting time is zero because in situation where is internal isolation or cell imbalance defect more you wait repair cost is increased.

This one had rotten fuse cover which leaked water inside fuse and fuse box. Owner responded on time, delivered vehicle and we repaired it same day.

Message to all owners to share this note:

All older Model s 2013 and 2014 if they never visited Tesla Service center to service any kind of battery issue, you probably have same problem waiting to happen (Tesla almost always change fuse cover if they remove battery for servicing).. Contact your service (Tesla or 3rd party) to make visual inspection and change the fuse cover.

There is one more preventive service what should be done is called “cleaning of umbrela valve cover and umbrela valves”

Errors: BMS_w123 and BMS_f123

Vehicle : Model S P85+ 2013

Mileage: 120000km

Warranty: out of 8 year warranty

Tesla battery cost: 9200€ + tax

EVC ISO repair : 1000€ + tax

Tesla Umbrela valve service :1200€+ tax

EVC umbrela valve service : 700€ + tax

In this case of ISO repair because of fuse cover, warranty is only for fuse cover resealing and fuse. Warranty for the rest of battery is not applied.

EV CLINIC and EV HUB joint venture enters “Beast Mode”

Our mission to accelerate EV 3rd party support across Europe enters 2nd gear and we do not joke about it, even batteries are shaking when they hear Štrom Trooper steps entering workshop, almost unbolting itself to comply with our repair demands. If Tom Cruise had us before, we would watch mission possible 8.

Project “Thor” 23.8.2022 : EV Hub customer from Oslo was stuck in Inssbruck at vacation, Tesla S85 with 9 years under belt and some 220 000km on clock took last breath and died. Then Nassir from EVHUB took some networking skills at test to deploy remote repair at rented/borrowed jacklift in FALCH BOSCH CAR SERVICE in Austria. Battery had cell imbalance at block #7. Job was started at 08:00h and finished completely at 17:00 o’clock. This task wasnt easy because we had unplanned setback. Someone before opened HVJB and damaged thread for interloop lidswitch. After battery defect detection and after full completion we had new error, BMS_F036 which means safety Interloop (HVIL) was broken. We suspect at first that maybe we made mistake and damaged rapidmate battery connector, but that was not the case, we needed 4 hours more to trace complete wiring to find lidswitch defect. Lidswtich bolt moved little bit and triggered error unrelated to battery defect, but we did it. Workshop owner was awesome,really helpful and Martin regional Bosch tech. That day Štrom Trooper went to Zagreb and “me” to Erlangen near Nurnberg

Project “Nik the mighty” 24.8.2022: This was training and repair task, not on one but on two hardest cases P85 called “weak short” or “short to brick” with doomsday error BMS_u029 which we researched before for 3 months. One car with defect block #10 and second with defect block #5. We took step by step, taking all safety measures and teaching Nikolas how to take proper steps from diagnose, opening the lid to repair and closing the lid. We started one by one Tesla at 09:00 and finished at 17:30 both Battery packs, and that could be guinness world accomplishment. Now our support and repair tasks are available at Niks Garage, all bookings and prices are managed by Nikolas.
