Ricardo to optimize in-car climate control systems to extend the range of electric vehicles

Ricardo has received UK Government funding to optimize in-car thermal and energy management systems to improve electric vehicle range and battery performance. This technology innovation should help accelerate consumer adoption of battery electric vehicles, the company said.

Partnering with Jaguar Land Rover and using a Jaguar I-PACE as a demonstrator vehicle, Ricardo engineers in the TOBEV (Thermally Optimized Battery Electric Vehicle) project will look holistically at whole vehicle thermal management and use state-of the art digital modeling techniques to optimize the thermal and control systems.

The research will optimize energy consumption and driver/passenger comfort, with the aim of increasing electric vehicle range by 5% while reducing overall cost by 10%. The project, with a total cost of £595,195 (US$804,187) has been awarded £297,597 (US$402,093) by the Office for Zero Emissions Vehicles (OZEV) in partnership with Innovate UK.

The UK Government has committed to banning the sale of new petrol and diesel cars by 2030. There is a real need for innovative technology solutions which will drive cost out of electrification and enhance electric vehicle performance, efficiency, safety and cost, to encourage consumer take-up.

Currently, the range of an electric vehicle is affected by hot and cold ambient temperatures. When drivers turn up the heat in their car in winter or enjoy air conditioning in the summer, electrical energy consumption increases, reducing the range of an electric vehicle by almost one third. To reduce thermal system energy consumption, individual technologies have been proposed in isolation without adapting the rest of the vehicle systems to take advantage of them.

In this project Ricardo experts will apply advanced control approaches which automatically establish the best way of integrating new components and thermal system architectures into electric vehicles, taking a system level approach.

Additionally, the project will seek to improve range by reducing energy consumption, product development time and costs through a predictive thermal management system using an electronic horizon. It will also optimize driver/passenger comfort using a ‘comfort controller’: an innovative approach to in-car passenger experience which will regulate heat sources to achieve a comfort level instead of a specified temperature.

This project is the latest in a long series of Ricardo UK Government-funded research and development projects proving technology solutions which help drive cost of out electrification, enhance EV battery performance or build capability and supply chains in critical sustainable electrification components.
