Solid-state cell with 3-minute charge

Researchers in the US have developed a solid-state lithium metal battery for use in future EVs that would fully charge in as little as 3 minutes (writes Nick Flaherty). The technology, which has a lifetime of 10,000 cycles, has been licensed by Harvard University to Adden Energy to scale up to pouch and then prismatic […]

48 V bidirectional charger for hybrids

EPC has developed a reference design called the EPC9165 for a 2 kW bidirectional charger in 48 V hybrid vehicles using GaN transistors (writes Nick Flaherty). Mild hybrids running on 48 V require a 48 to 12 V bidirectional converter, with power ranging from 1.5 to 6 kW. The EPC9165’s design uses a synchronous buck/boost […]

Hall effect sensors

The Hall effect has been the mainstay of magnetic sensing since it was discovered by US physicist Edwin Hall in 1879. The effect describes the creation of an electric field in a conductor that carries a current and is placed perpendicular to a magnetic field. The fact that the induced voltage is proportional to the magnetic field provides a measurement that is used to control brushless motors and the position of almost anything that rotates.
