Shell believes the future of electric vehicles isn’t bigger batteries—it’s smarter cooling. Its new Triple 10 concept aims to prove that lighter, more efficient EVs can charge in under 10 minutes using today’s charging infrastructure.
For years, car manufacturers have largely tackled range anxiety by fitting ever-larger battery packs into electric vehicles. While this has increased driving range, it has also made EVs heavier, more expensive and more resource-intensive to build.
Shell believes there’s another way.
Working alongside several leading British engineering companies, the energy giant has unveiled the Triple 10 concept—a road-ready technology demonstrator designed to show how advanced battery cooling could dramatically improve charging speeds and efficiency without relying on enormous batteries or ultra-high-power chargers.
If the technology reaches production vehicles, it could influence how the next generation of EVs is engineered across our wider EVs & Technology coverage.
What is the Triple 10 Challenge?
The name comes from three ambitious engineering targets:
- Charge Faster: Recharge from 10% to 80% in under 10 minutes.
- Go Further: Achieve an impressive 10 km per kWh of energy efficiency.
- Drive Cleaner: Reduce the vehicle’s lifecycle carbon footprint to around 10 tonnes of CO₂e—roughly half that of many current European electric vehicles.
Rather than focusing solely on battery size, the project concentrates on making every kilowatt-hour work harder.
A Different Approach to Battery Cooling
The biggest innovation is hidden beneath the bodywork.
Most modern EVs use complex water-glycol cooling systems that circulate coolant through pipes and cooling plates attached to battery modules. These systems work well but add weight, cost and complexity.
Shell’s concept replaces this with single-circuit immersion cooling.
Instead of cooling the battery indirectly, the individual battery cells are immersed in a specially developed electrically non-conductive thermal fluid. This allows heat to be removed much more efficiently while eliminating much of the plumbing found in conventional battery packs.
According to the project team, the simpler design reduces battery pack costs by around 25% while also making the vehicle lighter.
Charging in Under 10 Minutes—Without a 350 kW Charger
The headline figure is certainly eye-catching.
The Triple 10 concept can reportedly charge from 10% to 80% in just 9 minutes and 54 seconds.
Perhaps even more significant is how it achieves those speeds.
Unlike some of today’s fastest electric vehicles, which require rare 300–350 kW ultra-rapid chargers to reach their maximum charging rates, the Triple 10 concept delivers its performance using a 175 kW DC fast charger.
That’s important because 175 kW chargers are already far more common across public charging networks than 350 kW units.
If similar technology reaches production cars, drivers could enjoy significantly faster charging without waiting for an entirely new generation of EV charging infrastructure to be installed.
Efficiency Could Be the Bigger Story
While fast charging grabs the headlines, the efficiency figures may prove even more significant.
The concept targets an impressive 10 km/kWh.
For comparison, many current electric vehicles average around 5–6 km/kWh under mixed driving conditions.
That level of efficiency means manufacturers could achieve similar driving ranges using considerably smaller batteries.
Smaller batteries bring several advantages:
- Lower manufacturing costs
- Reduced vehicle weight
- Lower demand for raw materials
- Reduced tyre wear
- Improved overall energy efficiency
Instead of asking drivers to carry around ever-larger battery packs, the project suggests future EVs could become lighter and smarter.
Developed by British Engineering Specialists
Although Shell supplied the immersion cooling technology, the project brought together several respected British automotive engineering firms.
RML Group developed the battery pack architecture, using immersion cooling to simplify the pack and reduce its overall size.
Empel Systems designed a compact, high-performance electric motor and drive system optimised for the new cooling approach.
Vehicle integration and testing were carried out by HORIBA MIRA, which validated the technology under simulated extreme weather conditions using its advanced testing facilities.
The result is more than a laboratory experiment—it’s a fully functioning vehicle designed to demonstrate how the technology could work in the real world.
Shell Recharge Becomes the Focus
Alongside the unveiling of the Triple 10 concept, Shell announced it is consolidating its electric mobility technologies under the Shell Recharge brand.
Charging services, battery technologies and specialist thermal fluids will all sit under the same global identity as the company expands its presence in the EV market.
Tech Torque Media Verdict
The Triple 10 concept doesn’t simply promise another faster-charging electric car—it challenges one of the biggest assumptions in the industry.
For years, the solution to range anxiety has been bigger batteries.
Shell’s engineers are arguing that better thermal management and higher efficiency may be a smarter solution than simply adding more battery capacity.
If production vehicles can deliver sub-10-minute charging using existing 175 kW charging infrastructure while reducing battery size and improving efficiency, it could reshape how manufacturers design electric cars over the coming decade.
The Triple 10 remains a technology demonstrator rather than a production model, but its ideas deserve attention. Sometimes the biggest breakthroughs don’t come from adding more—they come from making better use of what we already have.
