POWER TO PERFORM Designed and developed by Jaguar Land Rover, the battery pack and electric motors enable optimum performance, efficiency and range The I-PACE Concept is powered by two synchronous, permanent magnet electric motors integrated into the front and rear axles. Each generates 200PS and 350Nm of torque and is paired with a concentric, single-ratio transmission. The driveshafts pass through the centre of the motors because this is the most space- efficient layout possible: the motors have an outer diameter of just 234mm and measure 500mm long. These compact dimensions deliver packaging benefits within the vehicle, contributing to the I-PACE Concept’s impressive luggage compartment volume. The motors are also light and extremely efficient, making them ideal for this high-performance electric vehicle. Response is immediate, and this instant torque delivery combined with all-wheel-drive traction enable the I-PACE Concept to accelerate from 0-60mph in around four seconds. As soon as the driver lifts off the accelerator pedal, the motors provide regenerative braking, comfortably slowing the vehicle down and recharging the battery in the process. Using the Drive button within the transmission controls integrated into the centre console, the driver can increase the level of regenerative braking, if desired. The corresponding increase in deceleration means that, in stop and go traffic, for example, the driver can drive with just a single pedal, with no need to apply the brakes to halt the car. > ELECTRICMOTORS The I-PACE Concept features a liquid-cooled, 90kWh battery comprising 36 modules enclosed within a structural aluminium housing. Each module contains the latest Lithium-ion pouch cells, which use Nickel-Cobalt-Manganese chemistry. These cells were selected for their combination of high energy density and because they can maintain a higher current for longer, which means that the battery can deliver both range and sustained performance. Compared to some other cell types, they also offer considerable future development potential. The state-of-the-art thermal management system ensures that the battery remains within its optimum operating temperature window for maximum efficiency and durability. A heat pump is an integral part of this system: by scavenging heat from the outside air to help warm the vehicle’s interior, the heat pump can deliver a double-digit increase in range – even in freezing winter conditions, when needed most. > BATTERY PACK 36 37 “The electric motors are hollow permanent magnet machines which, together with the concentric transmission, offer the best power density and efficiency and the lowest weight: they give the I-PACE Concept sports car performance” Dr Wolfgang Ziebart Technical Design Director, Jaguar Land Rover
