EV FAQ: Leapmotor T03 Charging & Running Cost Comparison

💰 How much does it cost per mile to drive a Leapmotor T03?

The Leapmotor T03 typically consumes 0.20–0.26 kWh per mile depending on driving conditions.
At an electricity cost of 8 p/kWh, the running cost is roughly 1.6–2.1 p per mile.


⛽ How does that compare with a petrol car doing 40 mpg?

At a petrol price of £1.50 per litre, a 40 mpg petrol car costs about 17 p per mile to run.

That means the T03 costs around 9–10 times less per mile than an equivalent petrol car.

VehicleCost per MileWeekly Cost (250 mi)Annual Cost (≈13,000 mi)
Leapmotor T03 (EV)1.6–2.1 p£4–£5£230
Petrol Car (40 mpg)~17 p£42–£43£2,200

⚖️ What electricity price would make an EV cost the same as petrol?

If petrol is £1.50/litre and the petrol car does 40 mpg, the equivalent “break-even” electricity price would be between:

  • 66 p/kWh (less efficient driving)
  • 85 p/kWh (very efficient driving)

So at today’s cheap rates (e.g. 8 p/kWh), driving electric remains dramatically cheaper.


🔌 Can I charge my Leapmotor T03 overnight using a granny cable?

Yes — a typical granny cable (10 A) charges at about 2.3 kW, adding roughly 11.5 kWh in 5 hours.

If you drive 50 miles a day, 5 days a week (250 mi/week) and use a low-tariff window from 00:30 – 05:30, you’ll:

  • Add about 11.5 kWh per night,
  • Use 11–14 kWh per day,
  • And easily make up any small shortfall by also charging Friday and Saturday nights when the car isn’t driven.

That keeps you comfortably ahead on charge each week.


🔋 Should I charge to 100% every night?

No — not usually.
For long battery life, it’s best to limit daily charging to around 80%.

You can charge to 100% occasionally (e.g. before a long trip), but sitting at 100% for long periods stresses the battery.


✅ What’s the ideal charging routine?

Here’s an optimal setup for your schedule:

SettingRecommended ValueWhy
Max charge level80%Best for long-term battery health
Start charging at50%Fits a 5-hour cheap-rate window (adds ~11 kWh)
Cheap window00:30 – 05:30Charges from ~50% → 80% efficiently
Weekend chargeFri & Sat nightsKeeps battery topped up with no driving load

This routine cycles the battery gently between ~50–80%, supports your 50 mile daily commute, and keeps you well within cheap-rate energy use.


🧠 Summary

  • EV running cost: ~2 p per mile, vs petrol ~17 p per mile.
  • Break-even electricity cost: ~66–85 p/kWh.
  • Granny cable overnight charging (2.3 kW for 5 h) easily sustains a 50 mi daily commute.
  • Best battery practice: charge to 80%, start at 50%, use weekend top-ups.
