Understanding Your Leaf’s Real Range
Because the Nissan Leaf uses a passively cooled battery system, it is more susceptible to degradation from London’s rapid charging infrastructure and temperature fluctuations than other EVs. A simple dashboard reading often doesn't tell the whole story. We provide a comprehensive mobile diagnostic service that plugs directly into your Leaf's CAN bus to extract real-time data from the Battery Management System (BMS). We identify cell imbalances that cause sudden percentage drops and provide a professional State of Health (SOH) report. This is essential for owners noticing range loss or for buyers wanting to avoid a vehicle with a "chemically masked" health reading.
