Battery Repair Smart 453 EQ

Troy fell because of horses and EV trust will fall because of this Smart 453 (not 451 which is 10x better). There is nothing worse to work on, repair and pay for defects. Each breakdown is €5,000 starting price up to €15,000. This one came from Belgrade with only 2000 km on the clock. The battery went into programmed BMS failure for unknown reasons. After that, the BMS is permanently locked, it cannot even drive or charge. This failure was unsolvable until we were the first in the world, after 6 months of work, (4 years ago) to crack the OTP programmed failure for the first time, to manually fix it in the eeprom of the SPC564 processor. Programming the BMS controller alone is not enough, as the newly created deep discharge failure was not resolved, recovery charging and balancing needed. The removal of this defect to an authorized service center costs €15,000 and there was no alternative before. This battery normally has 4 serial errors: internal instrument ISO ohmmeter defect, processor defect, programmed failure with amplifier how many times you activate the contact (180000), hardware error boot sector on 12V powerglitch bug, voltage drop due to low SOC discharge…etc etc. Most of the crying happens already at 20,000-30,000 km. It is advisable to recommend the vehicle to the mother-in-law, stepmother, ex-wife and other enemies.

Troja je pala zbog konja a EV povjerenje će zbog ovog Smarta 453 (ne 451 koji je 10x bolji). Nema goreg za raditi, popravljati i plaćati defekte. Svaki kvar je 5000€ start cijena pa sve do 15000€. Ovaj je došao iz Beograda sa samo 2000 km na satu. Baterija je otišla iz nepoznatih razloga u programirani BMS kvar. Nakon toga se BMS trajno zaključa, ne može ni voziti ni puniti. Ovaj kvar je bio ne riješiv dok nismo prvi u svijetu nakon 6mj posla (prije 4 godine) uspjeli provaliti po prvi put OTP programirani kvari, ručno ga otkloniti u eeprome SPC564 procesora. Samo programiranje BMS kontrolera nije dovoljno ukoliko se ne rijesi i novo nastali kvar dubokog praznjenja, zatim punjenja i balansiranja. Otklon ovog defekta u ovlastenom servisu košta 15000€ i nije bilo alternative. Ova baterija inače ima vise od 4 serijeske greške: defekt ISO ohmmeter unutarnjeg instrumenta, defekt procesora, programirani kvar sa projačom koliko puta aktivirate kontakt (180000), hardwerska greška boot sector na 12V powerglitch bug, voltage drop zbog low SOC discharge… itd itd. Većina plakanja se dešava već na 20000-30000km. Vozilo je poželjno preporučiti punici, maćehi, bivšoj i ostalim dušmanima.
