BMW verhoogt de capaciteit van het batterijen pakket van haar BMW i3 en i3s naar 120 kWh. De actieradius wordt daarmee aanzienlijk vergroot. Bovendien krijgt het interieur een make over.
In everyday use, the two models are now able to cover a distance of 260 kilometres*** – an increase of almost 30 per cent. In this way, BMW i is consolidating its position as an innovation leader and trendsetter in the field of pioneering electromobility with hallmark brand driving pleasure and excellent everyday practicality. Since the market launch of the BMW i3, the storage capacity of its high-voltage battery has been doubled, thereby increasing the car’s range as well. At the same time as the introduction of the new battery, a new body finish, a new colour for the optional interior design Loft and adaptive LED headlights with matrix function for the high beam are also available for the BMW i3 and BMW i3s. In future, a sports package will be available for the BMW i3 that includes black wheel arch surrounds and a sports suspension with specific dampers, springs and stabilisers, lowered suspension, a widened track and 20-inch light alloy wheels. The optimised guidance system in the tile design of the iDrive operating system is now available in conjunction with the optional navigation system Business. In future, the options telephony with wireless charging and wireless LAN hotspot will also be available for the BMW i3 and BMW i3s.
Ongoing progress in battery development: increased energy content while dimensions remain the same.
Like the electric motors and power electronics, the high-voltage batteries are an integral part of the BMW eDrive technology used in BMW i automobiles and developed independently by the BMW Group. Its lithium-ion cells are produced exclusively based on specifications defined by the BMW Group. Based on sound research and development work conducted in close cooperation with the manufacturer of the battery cells, consistent optimisation of the storage units is achieved in terms of power output, range, safety and durability. Installed deep in the floor of the vehicle, the high-voltage battery is produced at the BMW plant in
Dingolfing and consists of eight modules, each with twelve storage cells: the latest advancements have resulted in a capacity of 120 Ah along with a gross energy content of 42.2 kWh – while the size remains unchanged. This is yet another major step towards increased range. For comparison: at the market launch of the BMW i3 in 2013, the equivalent figures were 60 Ah and 22.6 kWh, while the second-generation battery introduced in 2016 reaches a level of 94 Ah and 33 kWh. In addition to vehicle weight and the installation space taken up by the highvoltage battery, driving performance and energy consumption likewise remain virtually unaltered by the increased range achieved by the latest advancements.
The BMW i3, powered by a 125 kW/170 hp electric motor, accelerates in 7.3 seconds from zero to 100 km/h, while the BMW i3s with 135 kW/184 hp completes the standard sprint in 6.9 seconds. This means that the two models both set the benchmark for sporty performance within their vehicle segment.
Thanks to spontaneous power delivery as is typical of electric motors, the BMW i3 and BMW i3s even reach the level of sports cars that have a considerably more powerful combustion engine: here the figures are 5.1 and 4.3 seconds respectively for the sprint from 80 to 120 km/h.
The combined power consumption of the BMW i3 (120 Ah) is 13.1 kWh per 100 kilometres*, while the BMW i3s (120 Ah) has a power consumption of 14.6 kWh to 14.0 kWh per 100 kilometres*. The high efficiency of the electric motor and the enhanced battery capacity result in a range that is nearly 30 per cent higher than that of the predecessor models. The range of the BMW i3 (120 Ah) is 359 kilometres* (previously 290 to 300 km) according to NEDC, and 285 to 310 kilometres** (previously 235 – 255 km) according to WLTP. For the BMW i3s (120 Ah), a range of 330 to 345 kilometres* (previously 280 km) has been calculated according to NEDC, and a range of 270 to 285 kilometres** (previously 235 –245 km) according to WLTP. In everyday conditions, both models now achieve a range of 260 kilometres*** (previously 200 km).
The high-quality charging electronics of the BMW i3 and BMW i3s allows fast and flexible refreshment of the energy reserves. The standard charging cable is designed to be plugged into a conventional household socket. Here the battery can be charged to up to 80 per cent of its full power in approximately 15 hours with a charging capacity of 2.4 kW. Connection to the BMW i Wallbox enables rapid three-phase charging with a capacity of 11 kW. Here the time required to achieve an 80 per cent charge of the large-capacity high-voltage battery is 3.2 hours. The power electronics and high-voltage battery in the BMW i3 and BMW i3s can also be used in conjunction with quick-charging stations that run on DC power. Here the charging capacity is 50 kW and the high-voltage battery reaches 80 per cent of its total power in just 42 minutes.
With its battery capacity increased to 42.2 kWh, the latest version of the BMW i3 also follows the brand’s holistic concept, applicable since market launch and geared towards responsible use of resources: this includes not just locally emissions-free power but also material selection and production techniques as well as mobility services. The BMW i3 (120 Ah) and the BMW i3s (120 Ah) have a much more favourable CO2 footprint across the entire vehicle lifecycle – from raw material extraction and manufacture through to use and recycling – and this makes for significantly lower global warming potential than is the case with comparable, conventionally powered automobiles.
