Understanding BMW i4 Charging
The BMW i4 has a 83.9kWh battery with a 11kW onboard charger. This means the car can accept up to 11kW from a Level 2 (240V) home charger.
The BMW i4's 11kW onboard charger means you won't benefit from chargers rated above ~48A at 240V, as the car itself limits the charging speed.
- The BMW i4 uses a J1772 / CCS1 port. Any J1772 Level 2 charger works. No adapter needed for standard residential EVSE units.
- All BMW i4 trims (eDrive35, eDrive40, M50, xDrive40) share the same 11kW onboard charger. A 48A charger is the sweet spot — going higher does not speed things up.
- BMW's included Mobile Charging Cable handles Level 1 and Level 2, but topping out at 5kW. An aftermarket 48A unit cuts that charge time nearly in half.
- A dedicated 240V circuit (50A breaker) is required for a 48A charger. Most electricians charge $200-$500 for a basic garage install. Check for local utility rebates, which often cover $100-$300.
- The i4 supports charging schedules via the BMW app. Pair it with a smart charger like the Autel MaxiCharger or ChargePoint Home Flex and you can set TOU (time-of-use) off-peak charging from two places.
Common Questions
Frequently Asked Questions
What is the best EV charger for the BMW i4?
We recommend the Autel MaxiCharger 50A as the best overall charger for the BMW i4. At $549, it provides 12kW of power and can charge your 83.9kWh battery from 10% to 100% in approximately 6.9 hours.
How long does it take to charge a BMW i4 at home?
With a Level 2 charger matched to the BMW i4's 11kW onboard charger, you can expect a full charge (10-100%) in about 6.9 hours. A standard 120V outlet (Level 1) would take significantly longer.
What amp charger do I need for the BMW i4?
The BMW i4 has a 11kW onboard charger, which means it can accept up to 48A at 240V. We recommend a charger with at least 48A output to maximize charging speed.
Can I use a Level 1 charger for my BMW i4?
Yes, but it's very slow. A Level 1 charger (standard 120V outlet) delivers about 1.4kW, which would take roughly 60 hours for a full charge of the BMW i4's 83.9kWh battery. A Level 2 charger is highly recommended.
Do I need to hardwire my EV charger for the BMW i4?
Not necessarily. Most chargers we recommend come with a NEMA 14-50 plug that works with a standard 240V outlet on a 50A circuit. Hardwiring is an option for some models and may be required by local code in certain areas.
