New Highly Advanced EV: No Brakes
New Highly Advanced Technology Replaces Traditional Brakes
Imagine driving a car with no traditional brakes! New technology called electric motor regeneration is enabling just that. In Paris, luxury automaker DS Automobiles, owned by Chrysler parent company Stellantis, has designed a highly advanced, electric car without conventional brakes. Called the E-Tense concept, the electric vehicle is very powerful and can accelerate from 0 to 62 mph in two seconds. It showcases the future of cars with no brakes. The car brakes and is stopped by using electric motor regeneration, a new technology that DS is deploying in its Formula E race car, the DS E-Tense Performance. The system uses two onboard electric motors to slow the vehicle through regenerative braking and charges the EV in the process when stopping.
How Does It Work?
This technology is fascinating. The DS E-Tense is built on the Formula E racecar's drivetrain and has a beautifully styled, futuristic design. This very classy EV pumps out an incredibly powerful 815 hp and 5900 lb-ft of torque. Regenerative braking slows and stops the car by two electric motors converting the vehicle's waste energy for immediate use or storing it for use when it's needed. During the braking process, the system generates new electricity for the battery. Currently some electric vehicles are using regenerative braking in tandem with traditional brakes. The big question that DS Automobiles is tackling is if regenerative braking is capable of braking the car on its own. There are very strong indications that it is capable. The technology is highly advanced and intelligent. The Formula E race car's regenerative brakes are so effective that they have made the traditional brakes on the car unnecessary and redundant.
Big Potential
The new braking system is inspired by electric car racing. DS is developing it in partnership with TotalEnergies, a France-based global energy company. According to DS, the new tech has "an innovative chemistry and an immersive cooling system for cells, at odds with current technology." In other words, this is potentially a significantly disruptive technology for EVs that could be breakthrough innovation. Some automotive experts believe that electric regenerative braking has the potential to significantly help with recharging the electric car's battery and that it will eliminate the need for traditional brake discs and pads.
