How their charging profiles differ
The BMW i3 (42.2 kWh) and BMW iX3 present different charging characteristics primarily driven by battery capacity and maximum charge limits.
Battery Capacity: The BMW i3 (42.2 kWh) features a 42.2 kWh battery, which is 43% smaller than the BMW iX3's 74 kWh pack. A larger battery offers more driving range but takes proportionally longer to charge at standard charge rates.
At-Home Charging (AC): Both vehicles share the same maximum AC onboard charger rate of 11 kW. This means they will draw the same maximum power from home wallboxes.
On-The-Road DC Fast Charging: The BMW i3 (42.2 kWh) accepts up to 50 kW DC, while the BMW iX3 supports up to 150 kW DC. The BMW iX3 has a faster DC limit of 150 kW, allowing it to charge faster on ultra-rapid chargers, assuming the station can supply the max power.
BMW Recommendation
For the BMW i3 (42.2 kWh), a standard 7.4 kW home wallbox is ideal for overnight charging. If you travel long distances frequently, look for DC fast chargers capable of supplying at least 50 kW to minimize charging stops.
BMW Recommendation
For the BMW iX3, a 7.4 kW home charger is also the perfect fit. Since it supports up to 150 kW DC, you will achieve optimal highway charge times by planning stops at charging stations rated 150 kW or higher.

Best Home Chargers for BMW i3 (42.2 kWh)
We analyzed charger speeds, compatibility, and durability to select the top home charging stations that match the specifications of the BMW i3 (42.2 kWh).
Optimal High-Power AC Charging
Your BMW i3 (42.2 kWh) supports high-speed AC charging up to 11 kW. To charge at maximum speed at home, we recommend a 48-amp charger (like the Tesla Universal or Emporia) hardwired to a 60-amp circuit. A standard 32-amp charger will still charge overnight but won’t take full advantage of your car’s faster onboard charger.
Tesla Universal Wall Connector
The most versatile charger on the market. It natively charges both Tesla (NACS) and standard J1772 vehicles with an integrated, auto-switching adapter.
- • Universal compatibility (Tesla & non-Tesla)
- • Sleek wall dock with auto-sensing latch
- • Tesla App integration (Wi-Fi smart features)
- • Power-sharing with up to 6 Wall Connectors
