\u26a0\ufe0f\u00a0The silent enemy: an unstable mains supply<\/strong><\/h6>\n
\n*Voltage drops (undervoltages)
\n*Harmonics and electrical signal distortion
\n*Installations without adequate protection
\n*These phenomena force the BCB to operate outside its normal parameters, damaging one of its most sensitive components: the Infineon IGBT.<\/p>\n\u274cThe critical point: burning of the Infineon IGBT<\/strong><\/h6>\n
\nWhen the network experiences power spikes or fluctuations:<\/p>\n
\nIt overheats quickly
\n*It can burn out, causing total failure of the BCB<\/p>\n<\/p>\n
\nThis type of failure is very common in Renault ZOEs and usually results in the need to repair or replace the BCB.<\/p>\n
\n*Errors related to the charging system on the dashboard.
\n*Frequent charging interruptions.
\n*In some cases, burning smell or overheating in the charger area.<\/p>\n\u2705\u00a0How to protect the BCB and IGBT.<\/strong><\/h6>\n
\n*Install surge protectors in your domestic electrical network.
\n*Avoid using low-quality plugs or extension cords.
\n*If you live in areas with an unstable network, consider using a voltage stabiliser
\n*Perform preventive maintenance to detect anomalies before the fault becomes irreversible<\/p>\n\ud83d\udccc\u00a0Conclusion<\/strong><\/h6>\n
\nPower surges and fluctuations not only damage the system, but can also cause the Infineon IGBT to burn out, leaving your car unable to charge.<\/p>\n<\/p>\n
\nIf your car has charging problems, we can help you diagnose, repair and protect the system to prevent future breakdowns.<\/p>\n
