Apps like Dr. Prius or devices like OBD2 Bluetooth scanners can help.
π Step 2: Remove and Test Battery Modules
- Disconnect the high-voltage battery safely
- Remove modules one by one
- Use a smart charger or discharger to test voltages
- Identify and isolate weak or imbalanced modules
π Step 3: Discharge and Recharge Cycles
Use a hybrid battery reconditioning charger or DIY light bulb rig to run multiple:
- Deep discharge cycles
- Slow recharge cycles
This helps re-balance the battery pack and improve overall performance.
π§° Step 4: Replace Dead Modules (Optional)
If certain modules are beyond recovery:
- Replace with matched used modules (same generation/voltage)
- Rebalance the entire pack to avoid imbalance stress
