BMW adds high voltage battery option for the i3 and the i3s

News
With cell capacity increased to 120 ampere hours (Ah) and a gross energy content of 42.2 kilowatt hours (kWh), a new generation of high-voltage batteries enables the BMW i3 (120 Ah) and the BMW i3s (120 Ah) to achieve a significantly further enhanced range as of November 2018.
Info

In everyday use, the two models are now able to cover a distance of 260 kilometres, an increase of almost 30%.

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.

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.

In addition to vehicle weight and the installation space taken up by the high-voltage 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.

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% 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.

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% 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% 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% of its total power in just 42 minutes.
