The Battery Management System (BMS) plays a critical role in maintaining your battery's health, ensuring proper charging rates, and balancing cell performance. Our specialized repair service diagnoses and restores functionality at the component level.
The BMS is the sophisticated brain behind your Tesla's battery performance, longevity, and safety. When it malfunctions, component-level repair can save you thousands compared to complete battery replacement.
Regulates charge and discharge rates to optimize performance. The BMS ensures your battery charges at the appropriate rate to maximize both lifespan and efficiency.
Prevents overcharging and undercharging, reducing the risk of battery damage. This critical safety function protects your valuable battery investment from potentially dangerous conditions.
Ensures proper cell balancing for long-term reliability. The BMS constantly monitors and adjusts individual cells to ensure they're working in harmony, extending overall battery life.
A malfunctioning BMS can manifest in various ways, affecting your Tesla's performance, range, and charging capabilities. Recognizing these signs early can prevent more extensive damage to your battery system.
Slow charging speeds, premature charging termination, or inability to charge at higher power levels like Supercharging.
Unexpected range drops, inaccurate range estimates, or sudden "battery low" warnings despite recent charging.
Dashboard warnings about battery health, performance limitations, or service requirements related to the high-voltage system.
Reduced power output, slower acceleration, or the vehicle entering a "limp mode" with restricted performance.
We specialize in component-level BMS repair, saving you thousands compared to full battery replacement. Our meticulous process ensures your Tesla's BMS functions flawlessly.
We perform comprehensive testing and analysis to pinpoint the exact BMS components causing issues, utilizing specialized diagnostic equipment designed for Tesla's high-voltage systems.
Our technicians repair or replace only the damaged components within the BMS circuit boards, using precision micro-soldering techniques and manufacturer-grade replacement parts.
Following hardware repairs, we reprogram and calibrate the BMS to ensure proper communication with your Tesla's battery modules and vehicle control systems.
We verify repairs through extensive real-world testing, including charging cycles, performance monitoring, and stress tests to ensure the BMS functions correctly under all conditions.
Our Tesla-specialized BMS repair service typically takes 2-5 days, depending on the complexity of the issue. Throughout the process, we follow strict quality control procedures and use ESD-safe equipment to protect sensitive electronics.
Schedule BMS DiagnosisInstead of replacing the entire battery system, our specialized BMS repair provides significant advantages.
BMS repair typically costs 70-90% less than complete battery replacement. For most Tesla models, this can represent savings of $5,000-$15,000 depending on the battery size.
Repairing rather than replacing preserves your existing battery, reducing waste and the environmental impact associated with manufacturing new battery packs.
Keep your original battery with its established wear patterns and predictable performance characteristics, avoiding the break-in period sometimes associated with new batteries.
A properly repaired BMS can restore your Tesla's original charging speeds, range accuracy, and power delivery, often making the vehicle feel "like new" again.
BMS repair is typically completed in 2-5 days, compared to potentially weeks for a full battery replacement, especially during periods of high demand or parts shortages.
Our technicians are specifically trained in Tesla BMS repair, with years of experience diagnosing and repairing even the most complex BMS issues across all Tesla models.
The customer's Model S suddenly limited charging speeds to 50 kW, preventing Supercharging at full speed. The car displayed multiple battery fault codes, and Tesla Service recommended a complete battery replacement.
Our diagnostic process revealed that two specific BMS boards had failed components: damaged voltage monitoring ICs and a faulty communication channel between modules. Rather than replacing the entire battery, we performed precision repairs on the affected BMS components.
After our targeted BMS repair, the Model S regained full Supercharging capabilities (250+ kW), all fault codes were resolved, and battery management returned to optimal performance. The owner saved over $15,000 compared to battery replacement.
"I was shocked when quoted nearly $19,000 for a battery replacement. Di Sabato's saved my Tesla with their BMS repair for a fraction of the cost. My Model S charges and performs like new again!"
Get answers to common questions about BMS repair services for Tesla vehicles.
Common signs of BMS issues include: reduced charging speeds or inability to use fast chargers, sudden range drops or inaccurate range estimates, battery-related warning messages on your dashboard, imbalanced cell voltages displayed in diagnostic apps, or unexplained power limitations. During our diagnostic process, we can definitively determine if BMS issues are causing your Tesla's problems.
BMS repair cannot reverse genuine capacity degradation in battery cells, which naturally occurs over time. However, BMS problems can sometimes cause the system to misread actual capacity, resulting in artificial range limitations. In these cases, repairing the BMS can restore the vehicle's ability to access the battery's true available capacity. Our diagnostic process can differentiate between BMS issues and actual cell degradation to determine the most appropriate solution.
If your Tesla is still within its battery warranty period (typically 8 years with mileage limits varying by model), BMS issues should be covered by Tesla. However, if your vehicle is out of warranty, our BMS repair service offers a cost-effective alternative to Tesla's battery replacement. Additionally, some owners with in-warranty vehicles choose our service due to faster turnaround times or when seeking more targeted repairs than what Tesla service centers may offer.
Most BMS repairs are completed within 2-5 business days, depending on the specific issues and your Tesla model. The process includes initial diagnostics (1 day), repair of affected components (1-3 days), and comprehensive testing (1 day). We provide more accurate timeframes after our initial diagnostic assessment. For customers who need continuous transportation, we offer rental assistance or loaner vehicles depending on availability.
Yes, all our BMS repairs include a 12-month warranty covering the repaired components and their functionality. If any issues arise with the repaired BMS components during this period, we'll address them at no additional cost. This warranty covers the specific BMS components we repaired, while maintaining your existing battery warranty status for other components. We also offer extended warranty options for additional coverage.
Don't replace your entire battery when a targeted BMS repair could solve the problem. Our component-level repair service restores functionality at a fraction of the cost.
