Range Rover Electric Prototype Previewed

[350Z]

Land Rover has commenced the testing of the upcoming Range Rover Electric through its paces at extremes of temperatures, from -40°C in the Arctic Circle, to +50°C in the searing deserts of the Middle East.

• The first tests have focused on the capability of the battery and Electric Drive Unit, effectively the vehicle’s core components including transmission, electric motor and power electronics in temperatures as low as –40°C.
• Both the battery and EDU are assembled in house by JLR in a first for the brand. Testing on the frozen lakes of Sweden has also demonstrated Range Rover’s new-in house all-electric propulsion system.
• The new traction control system distributes the wheel slip management task directly to each individual electric drive control unit, reducing the torque reaction time at each wheel from around 100 ms, to as little as 1 ms.
• Innovative software, developed in house by JLR, enables precise Electric Drive Unit (EDU) speed control for accurate management of wheel slip, reducing the need for ABS intervention.
• Traction is maximised on all surfaces with exceptional response and composed refinement, significantly enhancing the drive experience. This system works in harmony with the stability control and chassis systems.

Ford Motor Company have been testing vehicles in Finland at temperatures down to minus 45c for over 60 years. My friend worked there and married a Finish girl 50 years ago !!!
Ford now have an all year inside testing centre in Germany. Temperatures range from -40c to +55c. Vehicle and wind speeds of up to 250kmh at the push of a button, ( category 5 hurricane). They can simulate heavy snow at an altitude of 5,200 metres ( same as Everest base camp). Cross the Sahara desert, and get a 95% humidity soaking like Costa Rica.
28 spotlights with 4kw bulbs !!!! Simulate the sun.

Range Rover Electric prototypes have completed a second successful season of testing and development in the sub-zero conditions of the Arctic Circle.

• A key part of the latest development phase in Arjeplog, Sweden, has been for engineers to validate Range Rover Electric’s new ThermAssist technology.
• The frozen lake tracks also provided invaluable testing conditions for dynamics, including single pedal driving capability and switchable, twin-chamber air-suspension.
• The advanced on-board thermal management system reduces heating energy consumption by up to 40% and aims to recover heat to warm the propulsion system or cabin in ambient temperatures as low as -10C.
• The heat management technology ensures Range Rover Electric delivers optimised driving range, even in the coldest temperatures. It also minimises the impact of extreme temperatures on charging performance.
• The high-voltage 800V battery is the first one to be designed and built in-house at JLR. The 117 kWh battery is fully encased and smartly packaged, consisting of 344 prismatic cells in a double-stacked layout.
• Following its second season in Arjeplog, Range Rover Electric prototypes will continue their demanding testing and development programme ahead of client reservations.
