The regular diesel motor and gearbox have been replaced by a 70kW (94bhp), 330Nm electrical motor twinned with a 300-volt, lithium-ion battery with a ability of 27kWh, supplying a assortment of additional than fifty miles. In regular, lower velocity off-street use it can final for up to eight hrs prior to recharging. The battery can be thoroughly charged by a 7kW quickly charger in four hrs, or a transportable 3kW charger in 10 hrs.
The electrical autos (EVs) retain the Defender’s legendary four-wheel push system and differential lock. Simply because the electrical motor delivers most torque from the minute it commences, you will find no want for gear shifting and the transmission comprises a single velocity, two.7:1 reduction gearbox put together with the existing Defender four-wheel push system. A modified model of Land Rover’s Terrain Response® Process has also been included.
The autos were created by Land Rover’s Superior Engineering Staff adhering to thriving trials of the Defender-dependent electrical car or truck, Leopard 1. The vehicles’ ability has been examined in excessive and environmentally sensitive disorders, demonstrating capabilities not shared by typical street-likely EVs. Trials integrated pulling a 12-tonne ‘road train’ up a 13 percent gradient and wading to a depth of 800mm.
In retaining with Land Rover’s ‘Tread Lightly’ philosophy the clean, lower-velocity ability of the electrical drivetrain can make the Electric powered Defenders specifically very well suited to climbing road blocks without damaging the floor unnecessarily.
The battery weighs 410kg and is mounted in the entrance of the Defender in put of the diesel motor. Kerb body weight is 100kg additional than a essential Defender one hundred ten and ranges from 2055kg to 2162kg relying no matter if the entire body type is a decide on-up, difficult major or station wagon.
All the main elements in the electrical powertrain – together with the battery, inverter and motor – are air-cooled somewhat than liquid cooled, conserving a appreciable amount of money of body weight and complexity and including robustness. Regenerative braking has been optimised to this kind of an extent that utilizing Hill Descent Control, the motor can generate 30kW of electrical energy. Simply because the battery know-how can be charged extremely rapidly at a fee of up to 2 times its ability of 54kW without lessening battery everyday living, virtually all of the regenerated vitality can be recovered and saved. Up to eighty percent of the kinetic vitality in the car or truck can be recovered in this way, relying on disorders.
“This task is performing as a rolling laboratory for Land Rover to evaluate electrical autos, even in the most arduous all-terrain disorders. It presents us a prospect to evolve and check some of the systems that may just one working day be introduced into upcoming Land Rover products,” claimed Antony Harper, Jaguar Land Rover Head of Investigate.
Although there are no options for the all-terrain Electric powered Defender to enter collection production, the seven EVs will go into company in expert apps later this yr.
