Electric trucks are transforming commercial transport in India with low running costs, zero emissions, and smoother driving. But just like any vehicle, regular maintenance is essential to ensure peak performance, extend battery life, and avoid downtime.
In this detailed guide, we provide a complete EV truck maintenance checklist tailored for Indian fleet operators, logistics managers, and independent drivers.
⚙️ Why EV Truck Maintenance Matters
Although EVs require less maintenance than diesel trucks (no engine oil, no clutch, fewer moving parts), battery, software, and electrical systems still need attention.
Proper maintenance:
-
🛠️ Prevents sudden breakdowns
-
🔋 Extends battery life
-
📉 Reduces total cost of ownership (TCO)
-
📈 Ensures resale value
-
📊 Keeps uptime high for fleet owners
