Undocumented communication devices, including cellular radios, have been found in solar power inverters and energy storage batteries, according to Reuters. There is little additional information at this time: the news organisation has not been able to discover the identity of the manufacturers affected, and is not naming its human sources. While these undocumented links could simply be alternative routes for ...

Lyon-based ITEN has released more details of its 3.5 x 5.1 x 1.6mm surface-mount micro-battery, intended to be the main store in energy-harvesting wireless IoT nodes, and now due for release in Q3 of this year. Called PWY0150S, it will has a minimum capacity of 150µAh and a nominal 2.3V terminal voltage – actual charge-discharge range is 2.7 to 1.5V, ...

Toshiba has announced a 1.2kWh 27.6Vdc li-ion battery module for electric buses, ships and boats. Called Type4-23 (also FM01202CCB04A), it is electrically similar to the company’s existing Type1-23 in that it is 2P12S (24 cells in two parallel 12 series arrangement) module, but the earlier versions resin baseplate has been replaced by aluminium to improve heat extraction. “When used with ...

University of California San Diego and French lab CEA-Leti have got together to create a novel high-voltage drive for electrostatic and piezoelectric actuators in mini-drones, describing the technique at ISSCC in San Francisco this week. The aim is to deliver tens of miliwatts at tens of volts and ten of hertz into a highly capacitive load, all from a 3 ...

Cambridge-based specialist print head maker Xaar has signed-up two Chinese electric vehicle battery companies for its surface-coating technology. “Our work with Omijia and Shifang highlights Xaar’s commitment to advancing the EV industry by addressing critical challenges in battery manufacturing,” said Xaar CEO John Mills (both photos). Xaar is aiming at replacing traditional coating methods such as PET film with inks ...

Yamaichi is aiming at many-cell battery monitoring with a board-to-cable connector for FFCs (flexible flat cables) or FPCs (flexible printed circuit boards). It is a two part connector: one part for the board, and the other a stiffener assembly through which the flexi threads. The stiffener has a push-button locking mechanism to hold the flexi into the board part (see ...

Aqueous zinc-ion batteries are one potential solution to cost-effective grid-scale energy storage, as the raw materials are cheaper than needed for lithium-ion cells, and the extra weight of zinc is not much of a penalty in static applications. However, as zinc-ions electroplate onto and off of the anode, several destructive processes can occur, including the growth off needle-like ‘dendrites’ (think ...

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called NEH7100BU, it can mediate between a harvesting power source, a USB charger, a battery (or capacitor) and the load. To maximise power extracted from photovoltaic cells, which have variable output impedance, and embedded hill-climbing algorithm homes-in on the best operating point ...

At Electronica 2024 we caught up with Maria Hernández, Senior Product Manager at Qoitech, as part of our promotional coverage for the event. This interview explores how the Otii Product Suite from Qoitech empowers engineers to optimize battery life in IoT and embedded devices. We cover key steps, from device consumption profiling to battery profiling and emulation, helping teams achieve ...

Tokyo University of Science has trained AI with years of electrochemical research results to predict better electrode materials for sodium-ion battery positive electrodes. Sodium-ion batteries are seen as a lower cost alternative to lithium-ion batteries, for grid storage, for example, but the large sodium ions are difficult to store. The university is looking into a class of compounds called transition-metal ...
