When it comes to mass electric vehicle (EV) adoption, range anxiety has become one of the biggest roadblocks. A study by Cox Automotive revealed that over 80% of consumers have hesitated to purchase an EV due to concerns about its battery life.

To help ease some of these fears from drivers, Tactile Mobility is developing technology to enhance regenerative braking systems that aim to prolong the lifespan of EV batteries. The concept revolves around harnessing kinetic energy generated during braking and converting it into electrical power to recharge the vehicle’s battery.

“This is something that is a must have, because it’s almost no cost and increases the efficiency of the vehicle and the performance of the vehicle,” Boaz Mizrachi, the co-founder and chief technology officer of Tactile Mobility, told Straight Arrow News.

While this technology is already present in most fully electric and hybrid models, Tactile Mobility seeks to refine its efficiency to new levels. The transportation technology company is incorporating sensors that monitor various aspects of a vehicle’s performance in real time.

“If you can learn a little bit about the performance of your vehicles in different situations, you can extend the range and get better and faster regenerative charging,” Mizrachi said.

The data these sensors collect includes factors tire grip, vehicle weight, road friction and more. Compiling this information then allows the vehicle to make instantaneous adjustments, optimizing the amount of energy harvested through regenerative braking.

“If we can provide the exactly a new level, the exact friction coefficient that you have at each moment, when while you drive on the road, then you can use that and extend the magnitude of power harvesting while braking, the recuperative braking,” Mizrachi said. “And this, in turn will increase the battery range.”

By leveraging these advancements, EV drivers can expect extended driving ranges and reduced recharging costs. Industry experts believe these benefits will help the automotive regenerative braking market become worth over $26 billion by the end of the decade. Officials with Tactile Mobility said this technology will be universally adopted by automakers in the future.

“I think that in 10 years from now, maybe 15 years from now, every car will have a tactile software inside,” Mizrachi said.

PICTURE THIS.

YOU DECIDED TO BUY AN ELECTRIC VEHICLE.
YOU’RE CRUISING DOWN THE HIGHWAY WHEN SUDDENLY YOUR BATTERY RUNS OUT, LEAVING YOU STRANDED ON THE SIDE OF THE ROAD.

THE FEAR IS COMMON – SO MUCH SO IT’S BEEN DUBBED ‘RANGE ANXIETY’.
AND IT’S ONE OF THE BIGGEST CHALLENGES FACING MASS E-V ADOPTION.

A RECENT STUDY FOUND MORE THAN 80 PERCENT OF PEOPLE HAVE HESITATED PURCHASING AN ELECTRIC VEHICLE BECAUSE OF THESE CONCERNS.

BUT LET’S PUMP THE BRAKES A BIT – ONE COMPANY MAY HAVE A PASSIVE SOLUTION.

TACTILE MOBILITY IS WORKING TO PRODUCE REGENERATIVE BRAKING TECHNOLOGY THAT WOULD EXTEND THE LIFE OF A BATTERY.

“This is something that is a must have, okay, because it’s almost no cost and increases the efficiency of the vehicle and the performance of the vehicle.”

A MECHANISM WITHIN THE VEHICLE WOULD CAPTURE THE KINETIC ENERGY CREATED WHEN A DRIVER HITS THE BRAKES.

THAT ENERGY IS THEN CONVERTED INTO ELECTRICAL POWER WHICH CHARGES THE EV’S BATTERY.

WHILE MANY FULLY ELECTRIC AND HYBRID MODULES ALREADY UTILIZE THIS TYPE OF TECHNOLOGY, TACTILE MOBILITY IS TAKING THE EFFICIENCY TO A NEW LEVEL.

USING SENSORS TO MEASURE VARIOUS FUNCTIONS OF A CAR WHILE IT’S ON THE ROAD – THE VEHICLE CAN USE THAT REAL TIME DATA TO MAKE ADJUSTMENTS.
OPTIMIZING THE AMOUNT OF ENERGY CREATED FROM REGENERATIVE BRAKING.

KEEPING EV DRIVERS ON THE ROAD LONGER AND SAVING THEM MONEY ON RECHARGING COSTS.

“You can learn a little bit about the performance of your vehicles in different situations, what is the optimal speed, what is the optimal configuration of my adduction control, etc. And accordingly, you can extend the range and the better and faster regenerative charging.”

TACTILE MOBILITY BELIEVES THIS WILL BE A GAME CHANGER GOING FORWARD.

WITH EV-S PROJECTED TO HIT NEARLY 50 PERCENT OF AMERICAN AUTO SALES COME 20-35, THE COMPANY SAYS HOPES THEIR TECHNOLOGY WILL START BECOMING ALMOST UNIVERSALLY UTILIZED BY THEN.
