MORE ABOUT CHARGING
There are multiple ways to charge an EV:

Slow (Home and some Public Chargers)

Each EV has an inbuilt charger capable of receiving AC power. The charging port could have different fittings depending on where you are in the world. Even the same vehicle model sold in different countries could have different implementations.

Type 1 (SAE J1772 or "J Plug")

This plug is common in Australasia, Asia, the US and Canada.

Type 2 (IEC 62196 or "Mennekes")

This plug is common in Europe.

Fast Charging

Only available in some public chargers, this uses DC power to charge the battery directly. Each EV has a maximum speed at which it can be charged, and batteries are only fastcharged up to 80% capacity to ensure battery health. There are a number of different port configurations.

Many fast chargers will have multiple connectors, and power capacity (which is increasing as the technology improves).

CCS (Combined Charging System)
CCS ports are a combination of the slow charging port and an extra 2-pin socket. Therefore they can be either Type 1 or Type 2.

Type 1 CCS Combo
Type 2 CCS Combo

CHAdeMo

Developed in Japan, the CHAdeMO is common in vehicles such as the Nissan Leaf.

Tesla

Tesla developed their own fastcharge connector, although in some countries without proprietary Tesla chargers, the vehicle has a cable to adapt to CHAdeMO or Type 2 CCS.

How Fast Can An EV Charge?

Slow charging (home and public)
Slow charging is limited by the lower of: the EV's onboard charging speed, or the output of the wall-mounted charger you are plugged into. Charging speed is measured in kilowatts(kW). For example: your wall-mounted charger can output 32 Amps at 240 volts = 7.68 kW of power, however your EV's onboard charger is 6.6 kW - then that is the maximum speed. The higher the battery capacity, the more time it takes to charge.

Fast charging
DC fast chargers are being built with higher capacities, however this is still limited by the hardware limitations the EV manufacturer has placed on the battery. Most DC fast chargers start at 40kW (many have a much higher capacity).

BMW has confirmed the i4 electric sedan will be coming in 2021, and will be based on the iVision Dynamics concept vehicle. BMW claim that range will be 550-750 kilometres (340-435 miles) – this is probably an NEDC range. So real-world range would be 285-365 miles.

The i4 will be launched after the iX3 and iNEXT.
