Maximize savings: Schedule charging for off-peak hours (9 PM – 6 AM)
Tip #4: Maintain Your Charger
Monthly
- Check for damage
- Ensure connections are tight
- No water inside socket area
Yearly
- Professional inspection

Charging Habits for Home Charging
The Daily Routine
This is all it takes, every evening:
- 1 Park car at charger
- 2 Open charging port (side of car)
- 3 Plug cable into car
- 4 Tap app or press button to start
- 5 Go inside, have dinner, sleep
- ✓ Morning: Full battery, ready to drive
That's it. No more thinking about it.
Optimal Charging Strategy
Charge to 80% Daily
Only charge to 100% before long trips. Extends battery life significantly.
Charge at Night
Cheaper off-peak rates. Battery is cooler so charging is faster. Saves money.
Don't Fully Discharge
Keep battery above 20%. Extends lifespan. Just like your phone.
Consistent Habits
Same routine each day. Plug in every evening regardless of battery level.
💡 Follow these habits and your battery stays in perfect condition for 8–10 years!
Temperature Management
❄️ Winter
- Charging is slower (cold battery) — normal and safe
- Park in garage if possible
- Allow 10–15 min warmup
☀️ Summer
- Charging may be slightly slower (cooling kicks in)
- Park in shade when possible
- Never park in direct sun for hours

Check
- Is charging port open?
- Is cable firmly plugged?
