BMW i4 EV charging guide
The BMW i4 is a compact executive car with an enviable range of 257 – 365 miles.
BMW succeeds in providing a car with all the driving dynamics you would expect from a BMW, alongside the lengthy driving range and ultra-rapid charging you would expect from an executive EV, making it extremely versatile and ideally suited to everyday use.
Official WLTP Range
- 365 miles
Real-world Range
- 328 miles
How to charge the BMW i4
The BMW i4 uses the CCS charging standard, which consists of a combined AC and DC inlet port. The top portion of the inlet is for the Type 2 connector, which is used when charging at home, or at public slow and fast AC points. Both the upper and lower sections on the inlet are used to carry high power during rapid DC charging. The BMW i4’s CCS charging inlet is found on the off-side rear flank, where you might expect to find a fuel filler cap.
The BMW i4 is able to be slow, fast and rapid charged from public points, depending on the network and type of charge unit. In most cases, slow charging requires a 3-pin-to-Type 2 cable, and fast charging a Type 2-to-Type 2 cable, one of which is usually supplied with the vehicle. For rapid charging, the vehicle uses a tethered CCS connector which is part of the charging unit.
The BMW i4 uses two charging standards for its inlets – Type 2 and CCS. The Type 2 inlet is used when charging at home or at public slow and fast AC points. The CCS inlet is used to carry high power during rapid DC charging from a CCS connector.
Charging on AC or DC requires the EV driver to plug the connectors into the correct inlet, after which the car then ‘talks’ to the charging unit to make sure there is a power supply, that there are no faults, and that it is safe to start charging. If charging at home or at a workplace charge point, the vehicle then automatically starts charging.
On a public charger, an activation process is required to initiate charging. Depending on the network provider, this may involve the use of Zap-Pay, an RFID card or a smartphone app, often linked to an account which has been set up beforehand. Contactless pay-as-you-go units are also becoming more common on newer units. Once activated, the units will conduct further connection and account checks before starting to charge the vehicle.
How long does it take to charge the BMW i4
The BMW i4 is fitted with an 11 kW on-board charger for Type 2 AC charging as standard. This means that even when connected to a fast charger with a rated output above 11 kW, the BMW i4 will only be able to charge at up to 11 kW. BMW i4 models are capable of ultra-rapid charging at up to 205 kW DC.
The following table shows approximate times to charge the BMW i4. We recommend charging to 80% charge in order to protect the battery and maximise efficiency.
Note that the times shown are only a guide, as very rarely will an EV need to be fully charged from 0%. Other factors that might vary the charging time include ambient temperature, in-vehicle energy loads, any upper and lower charge restrictions to extend battery life and protect against potential damage, and charging rates slowing down as the maximum charge is reached.
| 7kW charging to 100% in hours | 22kW charging to 100% in hours | 50kW charging to 80% in hours |
|---|---|---|
| 12 | 8.25 | 1.1 |
Use our Home Charging Calculator to estimate charging times for the BMW i4. The level of battery charge, connector power rating, and on-board charger options can be tailored to your requirements for more accurate results.
How much does it cost to charge the BMW i4
The cost to charge the BMW i4 is primarily driven by the cost of the electricity, which itself varies by the type of charge point and the efficiency of the motor.
Zapmap monitors the cost of charging on a monthly basis. Our charging Price Index shows the weighted average PAYG pricing, based on real charging sessions for the previous three months.
The table below shows these prices split by power rating.
| Type of charging | Price per kWh |
|---|---|
| Home charging | 8p /kWh |
| Slow/fast charging | 57p /kWh |
| Rapid/ultra-rapid charging | 80p /kWh |
In general, home charging provides the cheapest per mile cost and public rapid charging tends to be around double the cost.
To find the cost and times to charge an EV on a public charge point, our Public Charging Calculator calculates charging costs for any new or used plug-in vehicle. The results can be personalised for different electricity costs and the level of charge required.
Charging the BMW i4 at home
To find the cost and times to charge an EV on a public charge point, our Public Charging Calculator calculates charging costs for any new or used plug-in vehicle. The results can be personalised for different electricity costs and the level of charge required. Charging at home is often the most convenient and cost effective way to recharge an EV. Government grants are available to help accelerate the provision of EV charge points in flats and rented accommodation, and a large number of companies offer a fully installed charge point for a fixed price.
Most home chargers are either rated at 3 kW or 7 kW. The higher powered wall-mounted units normally cost more than the slower 3 kW option, but halve the time required to fully charge an EV. Many plug-in car manufacturers have deals or partnerships with charge point suppliers, and in some cases provide a free home charge point as part of a new car purchase. We recommend shopping about beforehand as there are a number of suitable products on the market.
Charging the BMW i4 on the public network
The UK has a large number of public EV charging networks, with some offering national coverage and others only found in a specific region. Major charging networks include bp pulse, GeniePoint, GRIDSERVE, InstaVolt, Pod Point and ubitricity.
Payment and access methods across networks vary, with some networks taking cross-network payment solution Zap-Pay, others providing an RFID card and others a smartphone app to use their services. While most require an account to be set up before use, many rapid units now have contactless PAYG card readers.
Although some EV charge points are free to use, the majority of chargers require payment. Charging tariffs tend to comprise a flat connection fee, a cost per charging time (pence per hour) and/or a cost per energy consumed (pence per kWh).
