Software predicts future cell health

A machine learning algorithm could help reduce charging times and prolong battery life in EVs by predicting how different driving patterns affect battery performance (writes Nick Flaherty). Researchers from the University of Cambridge in the UK developed a non-invasive impedance-based approach to get accurate data on the state of health (SOH) of a battery. The […]

Modified anodes boost cell cycling

Researchers in South Korea have developed a new method of modifying conventional anodes to improve the cycling performance of a battery cell (writes Nick Flaherty). The team, at the Gwangju Institute of Science and Technology, used a layer of graphene oxide – a single atomic layer of carbon – on a silicon anode to prevent […]

Bespoke chips for drivetrains

STMicroelectronics has launched a family of microcontroller chips designed specifically for electrified drivetrains (writes Nick Flaherty). The Stellar P microcontrollers are automotive qualified and combine the CAN-XL in-car comms standard to handle the demand for more real-time data with actuation functions. The controllers are built on a 28 nm fully depleted silicon-on-insulator (FD SOI) process. […]

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 […]

Ammonia heralds smell of success

Amogy in the US has demonstrated its ammonia-powered technology in a heavy-duty electric vehicle for the first time (writes Nick Flaherty). The 100 kW tractor marks a 20-fold increase in the performance of the technology over the past year. It uses ammonia (NH3) with a fuel cell rather than hydrogen to provide access to a […]

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 […]

Cool approach to efficient air liners

GKN Aerospace has been working on cryogenic technology to boost the efficiency of hydrogen fuel cells and electric motors for aircraft (writes Nick Flaherty). The ‘hyperconducting’ systems proposed by the company use the liquid hydrogen stored in the aircraft as fuel as a heat sink, cooling the electrical conductors to temperatures below -200 ºC to […]
