The upcoming BMW iX Electric Luxury Sports Activity Vehicle (SAV) has received an EPA range rating of 324 miles (521 km) and over 300 miles even with bigger wheels.
BMW will initially launch a single iX xDrive50 version (twin-engine, all-wheel drive) in Q1 2022, equipped with a 111.5 kWh battery. Depending on the wheel size (20 “is standard), the EPA range will be as follows:
- 20 “rims (235 / 60R20 108H XL): 324 miles (521 km)
- 21 “rims (255 / 50R21 109H XL): 305 miles (491 km)
- 22 “rims (275 / 40R22 107Y): 507 km (315 miles)
The base price of the BMW iX xDrive50 is $ 83,200 (MSRP) plus $ 995 for the destination. After deducting the federal tax credit ($ 7,500), the effective price will start at $ 76,695.
In the future, the company will also introduce a more powerful solution BMW iX M60 model, with more than 600 hp. The entry-level xDrive40 version introduced in Europe will not be offered in the United States (at least not initially).
Let’s summarize the knowledge related to electric vehicles on the BMW iX.
The BMW iX xDrive50 has a large battery of 111.5 kWh (* 105.2 kWh net usable) which consists of prismatic battery cells. It is a standard 400 V battery system.
According to BMW, the gravimetric energy density of the lithium-ion battery has been increased by around 20% compared to the previous generation (no figures were provided).
Depending on the size and type of wheel, the EPA range will range from 305 miles (491 km) to 324 miles (521 km).
The vehicle has an advanced thermal management system – heating and cooling with heat pump. There is a function of preconditioning the battery before fast charging.
âThe heating and cooling system of the BMW iX consists of three cooling / heating circuits which can be interconnected by means of electric valves with a common expansion tank. When driving in low outside temperatures, for example , the excess heat generated by the drive units is used to reheat the high-voltage coil. A two-stage cooling module, a refrigeration compressor, two evaporators, a water condenser and a high-performance control unit together provide optimum temperature control for the BMW eDrive components and the vehicle interior in any operating condition and under all normal weather conditions. “
âThe latest version of the heat pump achieves a high efficiency factor by using ambient heat and heat from dehumidification – as well as waste heat from motors – for energy efficient operation. The integrated heating and cooling system also ensures optimum temperature control of the high voltage battery in very dynamic driving situations with high energy requirements and during rapid charging from a DC charging station. If the route guidance function of the navigation system is active and has programmed a stop at a fast charging station, the management will automatically precondition the battery beforehand.
Heating or cooling the high voltage battery as appropriate means that it will be at the optimum temperature for fast and efficient charging to its maximum capacity upon arrival at the charging station. Thermal management here takes several factors into account, including the current battery temperature, remaining range, expected charge rate, and expected charge amount as part of the overall route calculation. “
The BMW iX is based on BMW’s 5th generation eDrive technology, which includes highly integrated drive units (electric motor, power electronics and single-speed transmission in one housing). The power density of this 5th generation system is around 30% higher than before, according to BMW.
The electric motors – synchronous (without permanent magnets) – were developed and are manufactured in-house by BMW. Their efficiency is 93%.
The BMW xDrive50 specifically has two drive units – one at the front and one at the rear for a total system power of 516 hp (384 kW) and 564 lb-ft (765 Nm) of torque.
An important element that improves the driving dynamics of the all-wheel drive system is the all-new quasi-actuator wheel slip limitation technology.
âThis allows the vehicle to maximize straight-line acceleration even on slippery surfaces, thanks to extremely fast and precise control responses. Specially designed for the supply of instantaneous power to electric motors, this traction control system is integrated into the engine management. Signal paths to the control unit for DSC (Dynamic Stability Control), meaning that corrective inputs to the front and rear wheels are applied much faster and more precisely, with coordination between the front and rear wheels. “
Another valuable feature is advanced adaptive energy harvesting
“Intelligently connected driving management makes it possible to adapt the intensity of the braking energy recovery to the road situation, provided by the data from the navigation system and the sensors used by the assistance systems. When approaching an intersection, for example, the degree of recovery can be increased, while feeding energy back into the high-voltage battery and increasing the deceleration effect. This targeted control of deceleration by energy recovery increases autonomy.
In the United States, the BMW iX has an 11 kW single-phase on-board charger, which can fully recharge (0-100%) in 10 hours and 15 minutes.
DC fast charging power can reach 195kW and 10-80% recharge should take over 40 minutes.
BMW is partnering with EVgo to provide easy access to publicly accessible charging stations through a single app. Buyers and renters will also receive $ 100 in the form of an EVgo recharge credit that can be used at EVgo network stations and partners in all 50 states.
