Delphi announces combined inverter and DC/DC converter for Chinese market

Delphi Technologies plans to introduce what it says is the first combined inverter and DC/DC converter in China. The addition of these components is expected to create a more efficient and cost-effective way to deliver increased power density in a smaller and lighter package. The potential to deliver more efficient electric propulsion systems has already… Read more »

Garnet ceramic electrolyte helps block dendrite formation

Researchers at the University of Maryland have developed a new template that they hope will enable a safer alternative to liquid electrolytes, which have several drawbacks, including flammability, leakage and dendrite formation in the electrodes. In “Lithium-ion conductive ceramic textile: A new architecture for flexible solid-state lithium metal batteries,” published in Materials Today, UMD researchers… Read more »

Toyota develops new magnet cutting the use of rare earth element neodymium in electric motors

Scientists at Toyota have developed a new heat-resistant magnet that uses “significantly less” neodymium, a rare earth element commonly used in magnets for electric motors. Neodymium is critical for maintaining magnetization at high temperatures. The amount of neodymium in Toyota’s magnets has been reduced by up to 50 percent, partially replaced with lower-priced rare earths… Read more »

Sendyne’s new battery simulation tool boasts high accuracy, compact footprint

Battery management specialist Sendyne has unveiled new technology it says can predict cell and pack behavior of lithium-ion batteries with better than 5 percent accuracy in real time. CellMod, a lithium-ion battery simulation tool, has already been deployed by a US battery manufacturer. It’s designed to reduce design time and costs by employing rapid cell… Read more »

ICCT analysis: EVs are cleaner than ICE vehicles

Analysts with the International Council on Clean Transportation (ICCT) recently compared greenhouse gas (GHG) emissions of electric cars to emissions from cars equipped with combustion engines. The findings were not surprising. Among other things, the ICCT analysis indicated that the typical EV produces 50 percent fewer GHG emissions than the average passenger car in Europe…. Read more »
