Nissan Leaf Diagnostic Report

In this job, a Nissan Leaf with the 30 kWh battery pack was booked in due to range reduction despite healthy-looking battery state-of-health data. Our team carried out a full scan (no fault codes found) and a road test. We recorded a decline from the pack in cell 29, which indicated a failing cell inside the high-voltage pack. We isolated the fault to that specific cell without replacing the entire pack.

Nissan Leaf Repairs

The repair process for this Nissan leaf 30kWh cell replacement involved:

  • Safely de-energising the vehicle’s high-voltage system
  • Removing the high-voltage battery pack from the vehicle
  • Removing the battery cover and accessing individual cells
  • Replacing the defective cell (cell 29), then performing pack balancing procedures to ensure the new cell matched the rest of the pack’s performance
  • Reinstalling the pack, resealing, and verifying battery health under live data load

Resolution

Following the repair, the Nissan Leaf’s battery performance was restored: the range improved, the pack cell voltages were aligned, and the vehicle returned to normal operational condition. The specialist process of simply replacing a weak cell rather than the whole pack provided a cost-effective and efficient solution for this example of Nissan leaf 30kWh cell replacement.
