Battery Tesla Repair
The issue with "thin whiskers" losing contact in Tesla batteries, which are composed of cylindrical cells (often lithium-ion cells 18650 or 21700), is one of the problems that can arise with long-term use or improper maintenance of battery packs. This issue can emerge due to mechanical damage, fatigue phenomena in metal under cyclic loads, corrosion, or poor welding of the battery tabs to the internal contacts of the battery.
How the problem manifests:
- Decreased overall capacity of the battery.
- Increased internal resistance of the battery.
- Unstable operation of the battery.
- Loss of power.
- Inability to charge or discharge the battery to its full capacity.
Error codes: Tesla uses a variety of diagnostic codes to identify issues with batteries, but since they continuously update their software and diagnostic systems, specific error codes can vary. The exact error codes can be checked using Tesla's diagnostic equipment or by consulting with an official service center.
Solutions to the problem:
1. Inspection and replacement of damaged cells: If the problem is localized in one or several battery cells, they can be replaced.
2. Rewelding or repairing contacts: If the issue of lost contact is due to a weak connection, specialists might attempt to restore these contacts.
3. Complete replacement of the battery pack: In cases where many cells or the battery management system are severely damaged, it might be necessary to replace the entire battery pack.
For the diagnosis and repair of Tesla batteries, it's important to turn to qualified service centers, as unauthorized intervention can lead to additional damages or even cause a fire due to the peculiarities of lithium-ion batteries.
