Métode ngolah: 1 Nilai tampilan tegangan monomér rendah, sareng pangukuran nilai tegangan saleresna monomér dibandingkeun. Lamun nilai sabenerna leuwih luhur ti nilai tampilan, sarta nilai sabenerna standar pikeun LMU jeung nilai sabenerna tina nilai sabenerna. Tegangan monomér dikalibrasi; lamun nilai diukur konsisten jeung nilai tampilan, kasaimbangan ngecas manual dieusian.

2 Pariksa lamun garis sampling tegangan rusak, palsu; 3 ngaganti LMU; 4 pikeun ngaganti pak batré faulty. 3, tekanan diferensial: tekanan diferensial dinamis / bédana tekanan statik. Nalika ngecas, tegangan monomér gancang neukteuk off tegangan skip; nalika stepping on throttle nu, tegangan monomér turun gancang ti string séjén; nalika rem dihurungkeun, tegangan monomér gancang naek ti senar séjén.

Cukang lantaranana: 1 Nyambungkeun nut fastening kartu tambaga batré leupas; 2 permukaan nyambungkeun boga kokotor; 3 batré laju timer ngurangan badag; 4 sambungan las kawat listrik las kartu parunggu (hasilna string of monomér); 5 monomér individu Core leakage. Métode perlakuan: 1 Tighten nut; 2 Hapus sambungan permukaan awak asing; 3 pikeun ngeusi batre tunggal ka kasaimbangan muatan / ngurangan; 4 pikeun ngarobah pak batré masalah. 4.

Tegangan hop: Nalika kandaraan keur ngajalankeun atawa ngecas, tegangan monomér luncat. Cukang lantaranana: 1 titik sambungan garis kumpulan tegangan leupas; 2 Lum kasalahan. Métode perlakuan: 1 Tighten titik sambungan; 2 ngagantian LMU.

Kadua, gagalna kelas suhu 1, sesar manajemén termal; 1 kasalahan pemanasan (manaskeun); lamun suhu handap nilai a, nalika ngecas, pemanasan teu muka. Cukang lantaranana: 1 relay pemanasan atawa gagalna BMU; 2 lambar pemanasan atanapi sirkuit catu daya relay henteu normal. Métode ngolah: 1 Ngalereskeun atanapi ngagentos relay pemanasan atanapi BMU; 2 Pariksa sirkuit catu daya.

2 gagalna dissipation panas (kipas); sanggeus suhu luhur nilai nu tangtu, kipas teu jalan. Cukang lantaranana: 1 relay kipas atanapi gagalna BMU; 2 kipas atanapi relay sirkuit catu daya. Métode penanganan: 1 ngalereskeun atanapi ngagentos relay kipas atanapi gagalna BMU; 2 Pariksa sirkuit catu daya teu normal.

2, suhu luhur: a bangbarung alarem dina titik suhu nu tangtu dina sistem batré, ngajalankeun atawa ngecas. Cukang lantaranana: 1 sensor suhu gagal; kasalahan 2LMU; 3 sambungan listrik muriang lokal abnormal; 4 kipas teu dibuka, dissipation panas; 5 deukeut kana motor; 6 leuwih muatan. Processing method: 1 Measurement temperature sensor resistance value compares the display value, if the actual value is low, the same is the same as the other temperature value, then the LMU temperature value is calibrated with the actual value; 2 fastening electrical connection point Clear connection point foreign object; 3 ensuring the fan open; 4 new increased heat materials are isolated from the heat source; 5 suspend operations for heat dissipation; 6 immediately stop charging; 7 Replace LMU.

3, hawa low: bangbarung alarem dina titik suhu tangtu atawa sababaraha dina sistem batré, ngajalankeun atawa ngecas. Cukang lantaranana: 1 lepat sensor suhu; kasalahan 2LMU; 3 lambar pemanasan lokal abnormal. Métode ngolah: 1 Ngukur nilai lalawanan sensor suhu ngabandingkeun nilai tampilan, lamun nilai sabenerna leuwih luhur ti nilai tampilan, nilai sabenerna ieu calibrated jeung nilai sabenerna standar; 2 Pariksa lambar pemanasan perbaikan; 3 ngagantian LMU.

4, bédana suhu; tingal metode ngungkulan suhu luhur sareng rendah. Kodifikasi. Third, battery charging failure 1, DC charging failure; GB / T27930-2015 charging can not start, charging jump gun, SOC does not reset after charging.

Cukang lantaranana: 1 kasalahan batré (tegangan, suhu, insulasi jeung abnormal lianna) 2BMU sesar (modul ngecas atawa ngecas CAN abnormality) 3 négatip utama, ngecas relay lalawanan pasangan 4cc1 abnormal, CC2 pasangan tegangan taneuh abnormal 5PE métoda processing abnormal widang: 1 ngaluarkeun Batre Sesar 2 Perbaikan / Ngagantian Kagagalan Laporan Bagian 3. 2, AC charging failure; failure cause: 1 battery fault (voltage, temperature, insulation, etc.) 2BMU fault (charging module or charging CAN abnormal) 3 main negative, charging relay abnormally 4cc pair of earth resistance, CP pairs of ground voltages 5PE Abnormal processing method: 1 exclude battery failure 2 repair / replacement failure part 3 cut compption report, analyze the cause of failure.

Fourth, the reason for the failure of sealing insulation: the battery box or insert water, the battery is leakage, the environment is high, the insulation is false, the other high-pressure components of the whole vehicle (controller, compressor, etc.) are insulated. Treatment method: 1 positive pair, if there is a voltage or insulated resistance value of less than a predetermined value, the negative electrode circuit is discharged; the negative electrode pair, if there is a voltage or insulated resistance, the positive electrode circuit leakage is determined.

Titik leakage diitung dumasar kana nilai tegangan tunggal tegangan leakage dina waktos ieu, lajeng diolah nurutkeun kasus béda. 5. Unable to communicate or communicate failure LUM communication failure, BMU communication failure; the whole vehicle is 1 or several LMU information, or the whole car does not have BMS information.
