The BMW i3 (development code I01 ) is an electric car or plug-in hybrid vehicle from the car manufacturer BMW in the small car class . It is part of the BMW i sub-brand, newly founded in 2010, and the first production vehicle with a passenger cell made of carbon fiber reinforced plastic (CFRP). An electric motor with 125 kW serves as the drive. The range in the standardized driving cycle was 190 km in 2013. A petrol- powered range extender with 25 kW is optionally available in some markets outside Europe to increase the range . During its use, the drive works on the principle of the serial hybrid drive . In addition, sustainability requirements were also taken into account during production. 165,000 BMW i3s had been sold by the end of 2019, most of which were sold abroad.

Model history

Two concept vehicles , which anticipated the design, were presented at the IAA 2011 with the BMW i3 Concept and the BMW i3 Concept Coupé as a three-door variant at the LA Auto Show 2012.

The production version was presented on July 29, 2013 in New York, London and Beijing. The public premiere was formally held at the IAA of the same year. Production started on September 18, 2013 at the BMW plant in Leipzig . Sales began in Germany on November 16, 2013 and in the USA on May 2, 2014.

At the beginning of May 2016, a 94 Ah version of the BMW i3 with a 33 kWh battery was presented.

A facelift was carried out in 2017 and the BMW i3s model variant was  presented.

Another version was presented in September 2018, the BMW i3 120 Ah , see the facelift section . The 60 Ah version is no longer available. A version with a range extender is only sold in North America and Japan.

The BMW i3 will continue to be built until 2024 and will receive another update.

construction

body

The BMW i3 is around four meters long and has four seats. It consists of a chassis made of aluminum and a passenger compartment with a mass of 138 kg of carbon fiber reinforced plastic (CFRP). This combination of materials is lighter than a steel body, so that the vehicle weighing 1300 kg is on par with similar vehicles with combustion engines despite the heavy drive battery. With the exception of the roof, the outer skin consists of thermoplastic elastomers ( PP / ethylene-propylene-diene rubber ). 25% of the thermoplastic exterior parts are made from renewable materials or have been recycled . The roof is made of CFRP. The instrument panel and door panels are made from natural fibers. In addition to the luggage compartment in the rear of the vehicle, there is another small storage space under the front flap at the front of the vehicle, but this is not completely splash-proof. Since there is no motor to which cooling air has to be supplied, the BMW kidney grille is completely closed.

Because the batteries are installed in the vehicle floor, the BMW i3 is relatively high but has a low center of gravity. The vehicle does not have a B-pillar , but so-called portal doors, with the front doors on the BMW i3 being significantly larger than the rear ones. The seat belts for the front occupants are attached to the rear doors.

inner space

The vehicle offers a 260 liter trunk, which can be expanded to a flat loading area with 435 liters up to the lower edge of the window by folding down the rear seat backrest or 1100 liters when loading up to the roof. The loading sill is 78 cm high.

In the interior there is no center console below the dashboard, which means a lot of legroom for the front passengers. Because of the height of the vehicle, the seating position corresponds roughly to that in an SUV . The direction of travel is selected with a rocker arm on the steering column (by electrically reversing the motor). The front seats and the steering column are adjustable. There is a display on the dashboard directly in front of the driver on which the necessary data such as speed and range are shown. A second display in two possible sizes in the middle of the dashboard is available, for example, for radio information or the navigation device, which is available as an option. It is mainly operated via a central rotary pushbutton switch (" iDrive ").

technology

Electric motor

Drive of the BMW i3

The electric motor for the drive was developed by BMW itself and is produced in the Landshut plant. It weighs around 50 kg and is installed in the rear below the trunk. It is a hybrid excited synchronous motor , which means that it is mainly excited with permanent magnets made of NdFeB and that it is also excited with electrical current, as is used in reluctance machines. The use of rare earth metals can be reduced by 30 to 50% compared to conventional permanent magnet synchronous motors. It has a peak output of 125 kW (170 hp) and a maximum torque of 250 Nm. With the i3s, the peak power is 10 kW higher and is 135 kW. The number of pole pairs is 6 and the maximum speed is 11 400 rpm. It drives the rear wheels via an input gear with two-stage spur gear reduction . The gear ratio is 9.665. The motor is of type IB1P23M0.

Performance

The top speed of the vehicle is limited to 150 km / h, from 0 to 100 km / h the car accelerates in 7.2 seconds. The average energy consumption in the driving cycle is 12.9 kWh per 100 km. The range should be around 130 to 160 km, with an energy saving mode called "Eco Pro +" around 200 km (values ​​for the 60 Ah version without REX). The i3 with the 94 Ah battery without REX accelerates from 0 to 100 km / h in 7.3 seconds. The BMW i3s with its higher peak performance only needs 6.9 seconds to sprint to 100 km / h. The top speed of the i3s is limited to 160 km / h.

Range extender

As an option, a gasoline-powered was extended range (Range Extender, REX) available so that the i3 for plug-in hybrid is. A water-cooled two-cylinder - rows - Otto engine with the label W20K06U0 generated from 647 cc a nominal power of 28 kW (38 HP) at a speed of 5000 / min and a maximum torque of 55 Nm at 4500 / min. It has a bore of 79 mm and a stroke of 66 mm with a compression ratio of 11.6: 1. Its two chain-driven, overhead camshafts operate four valves per cylinder via bucket tappets . The same engine has been used in a more powerful version since 2012 in the BMW C 650 GT and BMW C 600 Sport scooters .

The generator connected to the engine can feed a maximum of 26.6 kW of electrical power at 5000 rpm. The additional (chemical) energy from a 9-liter fuel tank located in the front, the filler neck of which is on the right front fender, extends the range by around 120 to 150 km. It can be started if the charge level of the accumulator has fallen below 75%, or it starts automatically when the charge level of the accumulator falls below a certain threshold (7%). The motor only serves to maintain the charge level of the battery and only charges it to the extent that the charge level was when the range extender was activated. In addition, the engine occasionally starts automatically to avoid too long downtimes.

In the American model, the engine is operated according to a rule-based strategy in practice. Whether the engine is operated at all or the speed of the engine depends on the charge level of the battery and the driving speed. At a speed of 4300 rpm, the engine delivers a mechanical power of 25 kW, which is converted into 23.5 kW of electrical power.

The waste heat from the range extender is not used to heat the vehicle; it has its own separate cooling circuit. In 2015, employees at RWTH Aachen University used the BMW i3 to examine whether an operating strategy could be found in which the waste heat could still be used without reducing the noise level.

The range extender is primarily intended to reach the next charging station.

But it can also be used to drive the i3 for almost any length of time. To do this, you switch it on as early as possible (i.e. when the charge level is 75%), empty the range extender's tank, and then refuel at the next petrol station so you can continue to drive the range extender. The range extender can make the BMW i3 suitable for long journeys. At a speed of around 115 km / h, the range extender can permanently offset the energy consumption.

In October 2018 it was announced that the range extender will be discontinued in some markets with the introduction of the 42.4 kWh battery.

Battery technology

An i3 on a BMW i Wallbox

A total of 96 large-format lithium-ion accumulator cells from the supplier Samsung SDI are used as the drive battery in 8 modules in the BMW i3 . The battery is installed in the vehicle floor under the passengers. A conditioning unit consisting of heating and cooling elements is attached to the underside of the battery box.

The cells of the original model from 2013 are specified with 60 Ah charge capacity, which indicates the total amount of electricity that can be drawn. However, the voltage drops when discharging, from over 4 volts to a little over 3 volts, so that an average or effective voltage of a cell or all 96 is given. For reasons of durability, however, the cells are not allowed to be charged to their maximum or deeply discharged to zero, but only move within a certain voltage window.

i3 version	Capacity, gross	..., usable	nominal voltage
060 Ah	22.0 kWh	18.8 kWh	360 V
094 Ah	33.2 kWh	27.2 kWh	353 V
120 Ah	42.2 kWh	37.9 kWh	352 V

Despite the doubled nominal capacity, the size of the cells has remained the same and the mass has only increased marginally. The changed cell chemistry requires somewhat more careful handling; H. lower voltages. The nominal voltage has been lowered a bit for newer generations. Therefore, the actual energy capacities are somewhat lower than the names or charge capacities suggest.

The BMW i Battery Certificate guarantees at least 70% remaining battery capacity for 8 years or 100,000 km, whichever comes first. After a long-term test of 100,000 km, although partly driven with the range extender, 82 percent remaining capacity was measured.

The vehicle has a 12 V battery to supply the on- board network .

Reuse of old batteries

In cooperation with Vattenfall , BMW wants to reuse worn drive batteries in "second life" . Up to 1000 batteries from the Dingolfing plant with a capacity of 33 kWh each are to provide electrical control power to supplement wind farms .

Since October 2017, the BMW plant in Leipzig has had a stationary storage system made up of 500 old and new batteries from the BMW i3 to compensate for power fluctuations.

Use in other branches

The battery units are also available for watercraft such as the boat drive service provider Torqeedo. B. the Kaiser K625 used.

Load capacity

Charging the i3

The following options are available for charging the drive battery - some as special equipment:

• At a charging station with a type 2 plug, 16 A alternating current can be charged as standard. A full charge takes six to eight hours. The more powerful on-board charger (initially optional, later standard, 11 kW) can be used to charge in three to four hours. The BMW Wallbox wall charging station with a maximum of 4.6 kW is available as a suitable accessory . It requires a single-phase 230 V connection with a 20 A fuse.
• A normal household 230 V socket can be charged with 12 A using the standard ICCB charging cable. According to the manufacturer, a full charge takes eight hours. The desired amperage can be further reduced on the i3 in order to enable a charging process even with weak fuse protection, which is extended accordingly.
• In North America, the Occasional Use Cable can be used to charge NEMA  5-15 with 120 V AC voltage via a normal household socket on Level 1 . The charging times are 18 hours for the 60 Ah variant and 28 hours for the 94 Ah variant. The charging connection on the vehicle is an SAE J1772.
• With Level 2, via the additionally available BMW TurboCord, the vehicle can be charged in North America with 240 V AC and 20 A at 3.6 kW. The outlet required is a NEMA 6-20R. The charging time here is 5 hours for the 60 Ah variant and 8 hours for the 94 Ah variant.
• Shorter charging times can be achieved with direct current charging using the Combined Charging System (CCS). The Combo 2 charging socket and electronics required on the vehicle were offered as an optional extra in the package together with the more powerful on-board charger and has been standard equipment since 2018. With an output of 50 kW to 80%, charging takes a good 20 minutes. If the level continues to rise, the charging current is reduced. Charging from 80% to 90% also takes around 20 minutes, and charging from 90% to 100% takes around half an hour.
• In the Japanese version, DC charging is available using the CHAdeMO standard.
• Evatran has been offering a wireless charging system for the BMW i3 in the USA since the end of 2016.

The following charging capacities are achieved:

i3 version	Socket 120 V, 12 A	Schuko socket 230 V, 12 A (1)	Type 2 charging station		Combined Charging System, CCS
			single phase 32 A	three-phase 32 A	Direct current
060 Ah	1.4 kW	2.7 kW (2)	7.4 kW (3)	7.4 kW	50 kW
094 Ah				11 kW
120 Ah

⁽¹⁾Charging at a Schuko socket in connection with an in-cable control box

⁽²⁾Depending on the charging cable. Typically limited to 12A by the fuse protection of the socket and charging cable. A different ICCB charging cable has been supplied with the BMW i3 since 2017, the maximum charging power of which is limited to 2.3 kW (230 V, 10 A).

⁽³⁾In Germany, house connections are often limited to 4.6 kW (230 V, 20 A) to avoid unbalanced loads during single-phase charging. Public charging stations usually support the full 32 A.

Car body material CFRP

Honeycomb structure of a plastic element for energy absorption in the event of a frontal impact. Behind the dark gray i3 carbon body.

CFRP is used in motorsport and aviation , among other things . The problem is that carbon fiber reinforced plastic is currently several times more expensive than steel. While other manufacturers rely on conventional materials, BMW wants to reduce the cost of parts made of CFRP by a tenth through series production . The passenger cell of the i3 requires a third fewer parts than when using sheet steel, the production process, for example, saves time, and cathodic dip painting is no longer necessary.

The company SGL Carbon produces the fibers in a multi-stage process from polyacrylonitrile , the precursors of which are supplied from Japan by Mitsubishi Rayon, in a factory in Moses Lake in the US state of Washington . The energy for the production is obtained exclusively regeneratively from locally available hydropower. In the Upper Palatinate Wackersdorf are scrim made; the halls of the former WAA site are used; Four knitting machines will work for this on an area of ​​7,500 square meters .

The following important information is missing from this article:

There is a lack of evidence on the temperature data of the CFRP process and the innovation in the resin composition.

Help Wikipedia by researching and pasting it .

The use of CFRP as a body material in series production for the i3 is not new territory at BMW: Presses have been used at the BMW plant in Landshut since 2010 to manufacture the CFRP roofs for the BMW M3 and M6 . With investments of 40 million euros, three large presses are to be operated in the future, which are made of the fabrics soaked in resin ( Huntsman Advanced Materials Araldite LY 3585 with hardener XB 3458) in high-pressure resin transfer molding (HP-RTM) at 100 ° C and produce body parts at over 40 bar in less than ten minutes. Before this, the alignment and geometry of the parts are fixed with the Araldite LT 3366 binder. Up until now, this required closed ovens with temperatures of 500 ° C and several hours. The innovation concerns the composition of the resin and the greater pressure.

A recycling concept was drawn up for the material during development. When the i3 went into series production, 10% of the CFRP was made from recycled material.

landing gear

Some parts of the chassis are made of aluminum. The wheels are individually suspended: at the front on MacPherson struts and wishbones, a multi-link axle is installed at the rear . The steering works with a pinion and rack and there are hydraulically operated disc brakes on all wheels, but these are only used when braking hard, as the motor takes over most of the braking and part of the braking energy can be fed back into the batteries (recuperation) .

tires

In order to minimize the rolling resistance , the BMW i3 is equipped with quite large but narrow tires. The original equipment manufacturer Bridgestone , which was commissioned by BMW with the development, calls the concept "Ologic". It is supplied as standard with tire size 155/70 R19. The version with range extender is equipped as standard with wider tires measuring 175/60 ​​R19 on the rear axle. 20-inch wheels are also available for both versions.

Development and sales

The BMW i3 emerged from the “Megacity Vehicle” (MCV) project by BMW and SGL Carbon to reduce the weight of future cars. The concept vehicle BMW i3 Concept was presented at the IAA for the first time publicly demonstrated 2011th BMW CEO Norbert Reithofer said in September 2011 that he wanted to mass-produce the new i3 electric car and bring it to market at an affordable price: "The i3 will be cheaper than a 5-series BMW," said Reithofer.

The concept vehicle was presented with deep-glazed doors, but these were not taken over into series production. The production version was presented on July 29, 2013 in New York, London and Beijing. Production in Leipzig began on September 18, 2013. The i3 was shown for the first time at a trade fair at the IAA 2013. BMW launched the small electric car in Germany from 34,950 euros and in four interior versions (Atelier, Loft, Lodge and Suite).

The vehicles are offered under the sub-brand BMW i , and a hybrid sports car called “ BMW i8 ” was also created as part of the project . Sales in Germany are carried out by 33 BMW partners and 14 branches that have been selected directly by BMW and receive special contracts. Three carbon centers are planned in Germany (as of 2013) for repairs to damage caused by accidents on the new bodies.

It was launched in the USA in May 2014.

Facelift

The original version used Samsung SDI prismatic cells with an initial capacity of 60 Ah. Some time after Samsung improved the cells to 94 Ah, BMW took them over. On May 2, 2016, the new 94 Ah version of the BMW i3 was presented with a 33 kWh battery, which means that it has around 50% more capacity and electric range. It has been delivered since July 2016. The range in the standardized NEDC driving cycle is 312 km with standard tires (155/70 R19) and 300 km with option wheels with mixed tires (175 mm wide rear tires). BMW specifies a realistic range of around 200 km under everyday conditions.

i3s at its world premiere at the IAA 2017

On 29 August 2017 BMW presented the model life cycle pulses before (LCI) of the BMW i3 and the model I3S ; both were then presented at the IAA 2017. The body was slightly adjusted to make the vehicle look wider, and the overhangs have also increased slightly, so that the total vehicle length increased by one centimeter. The two new vehicles were presented in two colors, available for the first time for the i3, which are already familiar from other BMW model series (Melbourne Red and Imperial Blue). When painting, the A-pillar and the side line of the roof are no longer in the same color as the vehicle, but in black to make the vehicle appear flatter. The technical innovations include the standard full LED headlights , in which for the first time the high beam is also LED . The standard charging cable for the household socket now has a temperature sensor. Mixed tires have become standard on the BMW i3 LCI. On the BMW i3s, the tires are 20 mm wider, so the standard 20-inch tires are 175/55 at the front and 195/50 at the rear.

i3 facelift 2018

The BMW i3 120 Ah was presented in September 2018 . The energy content of the battery has now increased to 42.2 kWh; 120 Ah cells from Samsung SDI are used, which Samsung introduced in 2016. The BMW i3 120 Ah therefore has almost twice the capacity compared to the 60 Ah version from 2013. The BMW  i3s is also available with the new cells; the versions with range extenders are no longer available on the European market and are being made in the USA but still offered. BMW now specifies a practical range of 260 km. The new version could be ordered from October 8, 2018, delivery started in November 2018. The options DC fast charging and three-phase AC charging with 11 kW are now available as standard. Adjusted for equipment, the base price drops by € 540.

criticism

Telemetry

The BMW i3 sends via its own cellular module, e.g. B. data to BMW every time it is switched off; Initially unencrypted, after an update in 2015 now encrypted: the technical condition of the vehicle, the selected driving mode and the last charging positions. For example, BMW   uses a Last State Call to find out when the car will be started in the morning, how fast it was traveling and how much electricity it used. A movement profile of the vehicle could be created via this, which then also enables personal conclusions to be drawn. GPS data is collected and sent even if GPS positioning is "switched off" in the settings menu. Much of this data can also be easily read out / reconstructed from the control unit at a later date, e.g. B. by the buyer of a used car or a workshop technician, with which conclusions on the last few weeks of use of the (previous) vehicle user are possible. Other current BMW models also have this technology and send similar usage data to BMW.

In 2015, security gaps in the transmission of data by radio unit with regard to so-called "replay" attacks became known. In the meantime, this gap has been closed by means of a configuration change triggered by the mobile network; the transmissions were secured by activating the transport encryption of the data and checking the certificate of the communicating server.

Furnishing

Energy-saving heat pump heating is only available as an option. The more powerful on-board charger (11 kW) and the option of quick charging via CCS (with max. 50 kW) were initially optional until they were incorporated into the standard equipment in 2018.

Range extender

When operated exclusively with a range extender , the i3 has a very high fuel consumption that is not officially stated. The range is small because of the small tank size.

Fleet operation

Car sharing - vehicle from Innogy

BMW i3 are part of car sharing offers in many cities and municipalities . Examples are: In the Danish capital, a fleet of 400 vehicles was used by the manufacturer's DriveNow service from mid-2015 . In London, UK, 180 vehicles were available at DriveNow in early 2019. Innogy has been using 500 BMW i3s in Warsaw since the beginning of 2019.

Police authorities also use the BMW i3. Ten vehicles are used by the Bavarian Police. They are used for plannable trips. The range and the space available are criticized. The Los Angeles Police Department (LAPD) leased 100 vehicles in 2016, but these were little used until 2018.

Special designs

The i3 in the "Shadow Sport Edition" was available on the American market at the end of 2015.

In autumn 2019 the special edition "Edition Roadstyle", limited to 1000 pieces, appeared.

For the Consumer Electronics Show (CES) 2020 in Las Vegas , BMW built a test fleet of 20 i3 Urban Suites. In contrast to the production models, they only have two seats, the front passenger seat has been replaced by a footrest.

Registration numbers

Since the introduction of the i3, the annual registration numbers have risen continuously. In Germany, this is due, among other things, to the introduction of the environmental bonus .

In the first year, BMW sold 16,000 i3s worldwide, and in 2019 it should be around 40,000.
