Charging Cable for BMW I3s 120 Ah
The BMW i3s 120 Ah uses a Type 2 (Mennekes) connector and supports three-phase charging up to 11 kW. To utilize full capacity, you need a three-phase cable of at least 11 kW or 22 kW. A cable with lower capacity (e.g., 3.7 kW) won’t provide full charging speed.
Charging Station for BMW I3s 120 Ah
The maximum charging power for this model is 11 kW. Chargers with lower power (e.g., 3.7 kW or 7.4 kW) can be used, but this will increase charging time. Higher power chargers, such as 22 kW, are also compatible, but the car will charge at up to 11 kW.
Electrical Connection and Panel
The BMW i3s 120 Ah supports three-phase charging. To reach the full capacity of 11 kW, your electrical installation must be three-phase with minimum 3×16A. If you don’t have a three-phase connection yet, you can install a three-phase charger and temporarily use it on single phase. With a single-phase installation, the maximum charging power will be 3.7 kW.
Mobile Charging Device for BMW I3s 120 Ah
Mobile Charging Devices are practical for emergencies or as a backup option. They plug into a standard outlet (220V), but with a high battery capacity like 37.9 kWh, charging will be significantly slower. The mobile charger is recommended primarily as a temporary or supplementary solution.
