As soon as the person elements have been inspected for any injury, the stack is compressed by machine with a drive of 5 tonnes and positioned in a housing. The stack housing is manufactured within the mild metallic foundry at BMW Group Plant Landshut utilizing a sand casting method.

For this, molten aluminium is poured right into a mould comprised of compacted sand blended with resin in a course of specifically designed for this small-series car.

The strain plate, which delivers hydrogen and oxygen to the gasoline cell stack, is comprised of solid plastic elements and light-alloy castings, additionally from the Landshut plant. The strain plate varieties a gas-tight and water-tight seal across the stack housing.

Ultimate meeting of the gasoline cell stacks features a voltage check together with intensive testing of the chemical response throughout the cells. Lastly, all of the completely different elements are fitted collectively within the meeting space to supply the whole system.

Throughout this technique meeting stage, additional elements are fitted, such because the compressor, the anode and cathode of the fuel-cell system, the high-voltage coolant pump and the wiring harness.

Together with a extremely built-in drive unit utilizing fifth-generation BMW eDrive know-how (the electrical motor, transmission and energy electronics are grouped collectively in a compact housing) on the rear axle and an influence battery with lithium-ion know-how developed specifically for this car, the powertrain channels most output of 295kW / 401 hp onto the highway. In coasting overrun and braking phases, the motor additionally serves as a generator, feeding power again into an influence battery.

Manufacturing at Munich pilot plant.
The BMW iX5 Hydrogen is being constructed within the BMW Group’s pilot plant at its Analysis and Innovation Centre (FIZ) in Munich. That is the interface between growth and manufacturing the place each new mannequin from the corporate’s manufacturers is made for the primary time. Round 900 individuals work there within the physique store, meeting, mannequin engineering, idea car development and additive manufacturing.

They’re tasked with making certain that each the product and the manufacturing course of are prepared for collection manufacturing. Within the case of the BMW iX5 Hydrogen, specialists in hydrogen know-how, car growth and preliminary meeting of recent fashions have been working carefully collectively to combine the cutting-edge drive and power storage know-how.

Hydrogen permits speedy re-fuelling.
The hydrogen wanted to provide the gasoline cell is saved in two 700-bar tanks manufactured from carbon-fibre strengthened plastic (CFRP). Collectively these maintain virtually six kilograms of hydrogen, sufficient to offer the BMW iX5 Hydrogen a variety of 504 km (313 miles) within the WLTP cycle. Filling up the hydrogen tanks solely takes three to 4 minutes – so the BMW iX5 Hydrogen may also present the driving pleasure for which BMW is famend over lengthy distances, with just some, quick stops alongside the way in which.
