- Never use damaged charging equipment
Battery Care: What is the 80% Rule for EV?
Understanding what is the 80% rule for EV is crucial for long-term battery health, especially during monsoon:
The 80% Rule Explained:
- Charge your battery only up to 80% for daily use
- Reserve 100% charging for long trips
- Avoid letting battery drop below 20%
Why It Matters in Monsoon:
- Reduced Stress: Partial charging reduces battery degradation
- Better Efficiency: Maintains optimal performance in humid conditions
- Longer Lifespan: Extends battery life through careful cycling
Monsoon-Specific Tips:
- Charge more frequently but to lower levels
- Avoid immediate charging after driving through heavy rain
- Let the vehicle dry before plugging in
