In view of the evolution of sustainability and technologythe next generation Range Rover Electric It appears as a reference for what should be done regarding electric mobility, since under the vision of high-end performance and luxury, this vehicle is being subjected to demanding temperature tests with the aim of obtaining the highest possible performance.
In that sense, the first prototypes do their thing in some of the most extreme scenarios in the world: glaciers of the Arctic Circle and burning deserts of the Middle East. In this challenging context, the all-electric transmission demonstrates its ability to adapt and excel, ushering in a new era in luxury electric driving for Range Rover.
These test models are subjected to the most challenging environments on the planet, where the first tests have been directed towards evaluation of two fundamental elements of the vehicle: the battery and the electric propulsion unit.
These elements include the transmission, electric motor and power electronics. Thus, the tests have been carried out in extremely cold temperature conditions, dropping to -40°F (-40°C). It is important to note that both the battery and the EDU are being assembled in-house by Jaguar Land Rover for the first time in the brand.
Testing for electrical performance
The tests carried out on the frozen lakes of Sweden have revealed the performance of the Range Rover brand’s new all-electric propulsion system, a development that promises to further elevate the Range Rover’s performance on low-adhesion surfaces.
Thus, the software developed internally by Jaguar Land Rover It allows precise control of the speed of the electric propulsion unit, facilitating wheel slip management and reducing the need for intervention by the anti-lock braking system (ABS).
This translates into a maximizing traction on a wide variety of surfaces, accompanied by a serene response and refinement. These advances contribute significantly to improve the driving experience of the Range Roveroffering a feeling of greater control and security.
Additionally, this system operates with the stability control and chassis systems. “Range Rover with electric propulsion means the usual Range Rover luxury, refinement and capability, plus near-silent all-electric propulsion; with smooth and relaxed journeys without effort”, says Thomas Mueller, executive director of product engineering..
Extreme temperatures: enemy of electric vehicle batteries
Temperature is key to the performance of electric car batteries, since in extremely cold conditions, such as those found in severe winters, they can experience a decrease in their energy storage capacity and power delivery efficiency. .
This is because the chemical reactions inside the battery slow down at lower temperatures, reducing the availability of energy for power the electric motor and other vehicle systems.
On the other hand, in extremely hot climates, such as those found in desert regions, high temperatures can cause a increase in internal resistance of batteriesgenerating greater thermal stress and shortening its useful life.
Additionally, excessive heat can compromise the structural integrity of the battery cells and increase the risk of failure, triggering fires or explosions. Therefore, tests such as those carried out by Range Rover are vital to implement efficient thermal management systems that keep the batteries within an optimal temperature range, ensuring consistent and safe performance of the electric vehicle in any climate.
In response to these challenges, Range Rover is developing the electric propulsion unit, battery capacity, transmission, electric motor and power electronics to prevent freezing and improve performance in cold conditions. Finally, the design of the battery architecture and its location within the vehicle can also influence its ability to withstand and adapt to changes in temperature.
