Home and Destination Charging (0 -> 100%)

Charging is possible by using a regular wall plug or a charging station. Public charging is always done through a charging station. How fast the EV can charge depends on the charging station (EVSE) used and the maximum charging capacity of the EV. The table below shows all possible options for charging the BMW i3s Range Extender. Each option shows how fast the battery can be charged from empty to full.

Type 2 (Mennekes - IEC 62196)
Charging Point Car Uses Power Time Rate
Wall Plug (2.3 kW) 230V / 1x10A 2.3 kW 14 hours 6 mph
1-phase 16A (3.7 kW) 230V / 1x16A 3.7 kW 8h45m 10 mph
1-phase 32A (7.4 kW) 230V / 1x32A 7.4 kW 4h30m 21 mph
3-phase 16A (11 kW) 230V / 3x16A 11 kW 3 hours 31 mph
3-phase 32A (22 kW) 230V / 3x16A 11 kW † 3 hours 31 mph

† = Limited by on-board charger, vehicle cannot charge faster.

Rapid Charging (10 -> 80%)

Fastcharging is only possible at public charging points. Fastchargers enable longer journeys by adding as much range as possible in the shortest amount of time. As fastcharges will only charge a battery up to 80% of its capacity at full speed, the optimal fastcharge is between 10% and 80% SoC. The fastcharge rate of an EV depends on the charger used and the maximum charging power the EV can handle. The table below shows all details for fastcharging the BMW i3s Range Extender.

Combined Charging System (CCS Combo 2)
Charging Point Car Uses Time Rate
CCS (50 kW DC) 50 kW 25 min 150 mph
CCS (100 kW DC) 50 kW † 25 min 150 mph
CCS (150 kW DC) 50 kW † 25 min 150 mph

All about the BMW i3s Range Extender

Pricing

The BMW i3s Range Extender has a Recommend Retail Price (RRP) of £39,395 and an On The Road Price (OTR) of £40,125. The OTR Price includes VAT, first year of VED, vehicle first registration fee, number plates and delivery. The BMW i3s Range Extender is eligible for the Plug-In Car Grant (PICG) of £4,500. The grant will be applied to the final invoice price of the car. The OTR Price including the PICG for the BMW i3s Range Extender is £35,625.

Drivetrain and Performance

The BMW i3s Range Extender is a electric vehicle with range extender (EREV). The maximum power of the BMW i3s Range Extender is 135 kW (181 hp). The maximum torque is 199 lb-ft. The BMW i3s Range Extender is rear wheel drive and can accelerate from 0 to 62 miles per hour in 7.7 seconds. The top speed is 99 mph.

Battery and Charging

The battery of the BMW i3s Range Extender has a total capacity of 33.2 kWh. The usable capacity is 27.2 kWh. A range of about 90 miles is achievable on a fully charged battery. The actual range will however depend on several factors including climate, terrain, use of climate control systems and driving style.

For example: sustaining high speeds in cold weather could result in a range of around 65 mi. However, driving at low speeds in mild weather will increase the range to around 140 mi.

Charging is done using a Type 2 connector and the on-board charger has a maximum power of 11 kW. This charges a fully depleted battery back to full in around 3 hours. However, a 3-phase grid connection is needed to achieve this. The majority of homes and charge points currently do not have this connection. In most cases the maximum charging power will be 7.4 kW, allowing for a charge time of 4 hours 30 minutes and a charge rate of 21 mph. Charging the car using a regular wall plug will take around 14 hours.

Rapid charging is possible through a CCS connection. The maximum rapid charge power is 50 kW, which charges the battery from 10% to 80% in around 25 minutes. A rapid charge like this will add about 60 miles of range.

Energy Consumption

The combined (motorway and city) energy consumption of the BMW i3s Range Extender is about 300 Wh per mile in electric-only mode. By comparison, this energy consumption is the equivalent of a fuel consumption of 134 mpg in a traditional petrol car.

The actual energy consumption will depend on several factors including climate, terrain, use of climate control systems and driving style. For example: sustaining high speeds in cold weather could result in an energy use of around 415 Wh per mile. However, driving at low speeds in mild weather will increase the efficiency to about 190 Wh per mile.

Fuel Consumption

The BMW i3s Range Extender has a combined (electric and fuel) range of about 152 mi, of which about 90 of fully electric range. When driving in full-electric mode the petrol engine will never kick in; the car will drive fully electric until the battery is depleted or if 'range hold' mode is selected.

When the battery is empty or 'hold charge' mode is engaged, the fuel consumption is about 32 mpg on the combined (motorway and city) cycle. When starting off with a full battery and applying a moderate driving style, no fuel is consumed over a 15 mile trip and fuel consumption is about 0 mpg over a 30 mile trip and 0 mpg over a 60 mile trip.

The combined average consumption of petrol of the BMW i3s Range Extender will therefor depend on the average trip distance and whether the car is charged before each trip. Climate, driving style and route will have a further impact on the actual fuel consumption. The official figures in accordance with the NEDC driving cycle for fuel consumption of 405 mpg and a range of 81 mi are irrelevant in practice.

CO2 Emission

While driving in full-electric mode, the BMW i3s Range Extender will not emit any CO2. When the battery is empty, the internal combustion engine will be used. As fuel consumption and CO2 emissions are directly proportional, the average CO2 emssions of a BMW i3s Range Extender will depend greatly on several key factors that determine fuel consumption. Note: CO2 emissions are calculated per kilometre.

When driving using only the petrol engine, CO2 emissions will be around 209 grams of CO2 per kilometre on the combined (motorway and city) cycle. However, if the average trip distance is relatively short and the car is charged between trips, the average CO2 emissions will be reduced significantly.

CO2 Emissions will drop to 0 g/km on a 15 mile trip, 0 g/km on a 30 mile trip and 0 g/km on a 60 mile trip. This only includes tailpipe CO2 emissions. The energy needed to charge the battery might have been (partly) generated by the use of fossil fuels. Additionally, CO2 is emitted during the production and transport of fossil fuels. The offical figures in accordance with the NEDC driving cycle for CO2 emissions of 14 g/km are for comparison of vehicles only and have no relevance in practice.
