Sendyne patents new active cell balancing topology
Sendyne, a maker of battery measurement systems and modeling tools, has been awarded a patent for a novel active cell balancing topology. Active cell balancing is the process of transferring energy to and from individual cells in a battery pack so that all cells will operate at the same State of Charge (SOC). Because individual… Read more »
The DOE’s SBIR/STTR programs offer EV-related R&D funding for small businesses
The DOE has announced a new batch of topics for the 2016 Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) programs. Under the SBIR and STTR programs, federal agencies set aside portions of their R&D budgets for small businesses. Companies that win awards keep the rights to any technology developed, and are encouraged… Read more »
The future of integrated inverters: Press-fit solderless interconnects and smarter design
Interplex, the complex assemblies expert, on power electronics, the automotive industry and the continuous drive for smarter design Power modules containing high-power insulated-gate bipolar transistors (IGBTs) are at the core of most modern inverters. These modules are the electronic muscle of the system. They perform all the switching, and they generate all the heat. But… Read more »
