About the Service.

Your EV’s battery management system (BMS) controls how energy is stored, used, and reported across the vehicle. Over time, or after component replacement, this system can lose calibration, leading to inaccurate range estimates, poor charging behavior, or battery wear. At EVS, our BMS calibration service realigns system readings with actual battery performance. Whether you drive a full EV or hybrid, we help restore battery accuracy, safety, and efficiency.

Benefits of BMS Calibration

Improved Range Accuracy

Your dashboard range estimates better reflect actual battery charge and real-world driving habits.

Balanced Cell Performance

Calibration helps balance cell voltages and prevents uneven battery cell degradation.

Charging System Optimization

Ensures correct interaction between the charger, battery pack, and vehicle control software.

Battery Life Extension

Reduces stress on battery cells by restoring accurate energy flow limits and thresholds.

Reset After Repair

Essential after battery pack replacements, module swaps, or major software updates.

Hybrid and EV Support

Calibration procedures apply to both fully electric vehicles and plug-in hybrid systems.
