Madhuchhanda Palit, an Automotive Analyst at GlobalData, emphasized the importance of improving battery range for EVs. She stated, “Improving battery range for EVs has been crucial for increasing adoption rates, with regenerative braking emerging as a key innovation. This technology recovers kinetic energy usually lost as heat during braking, converting it into electricity to recharge the battery, thus extending the vehicle’s range. Regenerative braking is also used in hybrid and internal combustion engine (ICE) cars to cut fuel consumption, reduce exhaust emissions, and meet stringent emission standards. Adoption of this technology is steadily growing.”
Palit also noted the growing popularity of specific braking technologies. She explained, “On the other hand, specific technologies are gaining popularity and have already formed a market. For example, resistive braking motors are employed in situations where the motor speed surpasses the speed set by the variable frequency drive (VFD) or when quick deceleration is required. These motors can provide controlled braking with enhanced torque, which makes them especially beneficial in electric vehicles.”
The steady growth in adoption rates of regenerative braking and resistive braking motors showcases the industry's commitment to innovation, safety, and efficiency.
Key companies in the automotive sector, such as Bosch and ZF, are innovating to address various concerns, including emissions and maintenance costs. Bosch's iBooster and ZF's electro-mechanical brake system significantly reduce brake dust emissions and improve braking performance.
Bosch has developed a vacuum-independent regenerative braking system called iBooster. This system aims to significantly reduce brake dust emissions. ZF, on the other hand, has introduced an electro-mechanical brake system. This system generates braking force at each wheel using an electric motor, eliminating the need for a hydraulic system and brake fluid.
“While the electrical braking systems market is expected to grow at a healthy rate, the foundation braking system, i.e, drum and disc brakes market is expected to decline over the forecast period. This is due to stringent emission regulations, as friction-based systems generate brake dust, a major contributor to non-exhaust emissions, and frequent wear and tear increases maintenance costs. Additionally, the rapid growth of electric and hybrid vehicles is set to boost the electrical braking system market,” Palit said.
ZF's system also offers shorter braking distances, better recovery of braking energy, and lower maintenance costs. The overall trend is moving towards electrical braking systems, driven by the growth of electric and hybrid vehicles and stringent emission regulations targeting brake dust.
