Jaguar is giving I-PACE customers a complimentary update that will provide increased real-world range. Engineers applied advanced technical insights from the Jaguar
I-PACE eTROPHY race series to optimise the management of battery, thermal and AWD systems to enhance the efficiency of the all-electric powertrain.
The all-wheel drive I-PACE is Jaguar’s first full battery-electric vehicle and has a range of up to 470km (292 miles) from a single charge of its 90kWh Lithium-ion battery (WLTP cycle). While the new software upgrade doesn’t change the official certified range figure, the marginal gains developed will give customers access to an improvement of up to eight per cent dependent on usage – equating to a potential extra 20km (12 miles) of real-world range.
Jaguar in 2018 created the I-PACE eTROPHY series – an all-electric production based international race series – reinforcing its commitment to electric racing whilst leveraging technical expertise to develop future electric road cars as part of its ‘Race to Innovate’ mission. The series puts the all-electric SUV through extreme use conditions and the first competitive season yielded critical learnings for the durability and thermal control of the battery and torque management systems.
In a continual quest to enhance customer experience, Jaguar engineers have also analysed data from more than 80 million kilometres (50 million miles) of real-world journeys from all corners of the world. Every element of the vehicle’s performance is scrutinised to leverage the optimum performance of the systems and maximise efficiency, said the company in News Release.
The changes derived from the eTROPHY race series include:
• All-Wheel Drive: Changes to the torque distribution between the front and rear motors will deliver greater efficiency when driving in ECO mode – the system still delivers permanent AWD traction
• Temperature control: Refinements to thermal management control will make greater use of the active radiator vane system, closing the vanes more frequently to enhance aerodynamic performance more of the time
• Battery Capacity: Updates allow the battery to run to a lower state of charge than previously without affecting driveability, durability or performance
Additional changes derived from real-world data analysis include:
• Regenerative Braking: The vehicle’s brakes will harvest energy more efficiently when the battery is in a high state of charge and the amount of energy recovery has been increased at lower driving speeds to maximise efficiency and range
• Range calculation: Changes to the predictive range calculation algorithm will deliver a more accurate and consistent estimate of vehicle range, while being more reflective of an individual’s driving style
