How to tell when an EV battery may need replacement
Reduced range and longer charging times can be signs to inspect an EV battery, but NexDrive says technicians check state of charge and state of health before deciding whether replacement is necessary.
TLDR
Reduced range and longer charging times can signal EV battery degradation, but they do not by themselves show that a full replacement is needed. NexDrive says technicians assess state of charge and state of health, while Delphi says battery health below some manufacturers’ 70% to 80% warranty thresholds does not always mean the pack must be replaced.
