BorgWarner said it expects 48-volt mild hybrid technologies to be crucial in delivering the fuel-efficiency, features and performance consumers demand, in addition to systems for full-hybrid and battery electric vehicles (BEVs). The company added that it foresees a global shift in propulsion demands, and has been developing one of the broadest ranges of readily-available technologies for 48-volt mild hybrids in the industry. This is anchored by its 2015 acquisition of Remy International and its agreement to acquire Sevcon later this year, noted BorgWarner. The company is claimed to be focusing its deep systems-level expertise to develop one of the broadest 48-volt portfolios in the industry.

BorgWarner expects 48-volt systems to capture over 60 % of the global hybrid vehicle market, with an annualised production rate of about 25 mn units by 2027. The company’s 48-volt system solutions capture and use waste energy in the most efficient way, providing more power, efficiency and functionality, it explained. It added that mass production of its eBooster solution is currently ramping up with the system launching first with three global automakers, including Daimler’s latest 3 l petrol engine.

BorgWarner is showcasing its range of combustion, hybrid and electric technologies at the International Motor Show (IAA) Cars in Frankfurt, Germany, and Electric & Hybrid Vehicle Technology Expo in Michigan. These technologies include eBooster electrically-driven compressors, iBAS, on- and off-axis P2 modules, eAWD electric drive modules, one-way clutches, electric rear drive modules (eRDMs), electric motors, power electronics and efficient transmissions.

James R Verrier, CEO, BorgWarner, said the company is excited about the demand and opportunity for electrified vehicle technologies – it is a turning point for the industry. “We believe 48-volt systems offer the high-volume economics that will get us to the ultimate destination of a cleaner, more energy-efficient world,” added Verrier.

Operating in multiple 48-volt product areas allows the company to perfect how the individual technologies function as a system, noted Christopher P Thomas, CTO, BorgWarner. An example would be a 48-volt system that incorporates an eBooster electrically-driven compressor and an iBAS to determine the optimal control strategy to most-effectively convert charge in the battery to needs of the propulsion system, he explained. Thomas added that this results in efficiency gains that enable engine right-sizing and more optimal matching of the turbocharger and driveline components, creating opportunities for automakers in packaging space, architecture, design and efficiency.
