In a bid to strengthen its inverter capabilities and offerings, BorgWarner has established an exclusive licensing agreement with PolyCharge America, Inc., a startup company formed to deliver disruptive capacitor products.
With this agreement, BorgWarner secures exclusive rights to bring the PolyCharge NanoLam capacitors in-house for use in the company's extensive selection of inverters. A press release from BorgWarner said that the capacitors enable high-power inverters to be smaller, lighter, and more tolerant to high temperatures.
The PolyCharge capacitors will be taken in-house at BorgWarner's Singapore facility.
PolyCharge's NanoLam capacitor technology utilises super-thin polymer dielectric layers, making them ideal for applications in which weight savings, high-temperature tolerance and packaging space are critically important. NanoLam capacitors are self-healing, prismatic in shape, and offer a 50% reduction in capacitor size and weight, making them ideal for applications with challenging packaging requirements across a broad voltage range.
Compared to traditional polypropylene DC-link capacitors, PolyCharge NanoLam products offer significantly higher energy density, higher ripple current ratings, and lower inductance resulting in improved efficiency and higher power density inverter systems.
Dr Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems, said, 'As a leader in delivering innovative and sustainable mobility solutions, we are constantly assessing our technology portfolio and existing partnerships for potential opportunities to strengthen our technology offerings. This licensing agreement bolsters our relationship with PolyCharge, aligns with our comprehensive electrification strategy, and complements our inverter portfolio. Because the high-voltage inverter market is growing rapidly, given the critical role they play in electrified propulsion, our ability to condense packaging size and weight through PolyCharge's capacitors will give our customers a significant advantage.'
Steven Yializis, Chief Operating Officer and Director of PolyCharge America, said, 'The team at BorgWarner has been instrumental in getting NanoLam technology to the point where it is today. This agreement is a testament to BorgWarner's commitment to sustainable mobility as well as a major step in achieving PolyCharge's mission of 'A NanoLam Capacitor in Every Vehicle.''
