Quantum leap for cell current tests

Researchers in Japan have used a quantum sensor with a wide dynamic range and high sensitivity to measure the current in a battery pack more accurately than traditional techniques (writes Nick Flaherty). The team, from Department of Electrical and Electronic Engineering at the Tokyo Institute of Technology, took a quantum sensor built from artificial diamond […]

High-power modular EV cell cycler

NI has launched a battery cycler that supports testing packs with a power of up to 150 kW (writes Nick Flaherty). The High Power System (HPS) 17000, NI’s highest voltage cycler at 1500 V, is modular to support existing EV architectures while leaving room for future higher-voltage variants. It is used to analyse battery function […]


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.
