How their charging profiles differ
The BMW i3 (42.2 kWh) and Tata Tiago.ev (Long Range) 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 76% larger than the Tata Tiago.ev (Long Range)'s 24 kWh pack. A larger battery offers more driving range but takes proportionally longer to charge at standard charge rates.
At-Home Charging (AC): The BMW i3 (42.2 kWh) has a higher onboard AC charger rate of 11 kW, compared to the Tata Tiago.ev (Long Range) which is limited to 7.4 kW. On 11kW or 22kW three-phase chargers, the vehicle with the higher AC rate will charge substantially faster.
On-The-Road DC Fast Charging: The BMW i3 (42.2 kWh) accepts up to 50 kW DC, while the Tata Tiago.ev (Long Range) supports up to 50 kW DC. They will charge at identical speeds when connected to high-power DC rapid chargers.
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.
Tata Recommendation
For the Tata Tiago.ev (Long Range), a 7.4 kW home charger is also the perfect fit. Since it supports up to 50 kW DC, you will achieve optimal highway charge times by planning stops at charging stations rated 50 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.
